A smart thermostat without a c wire is a thermostat that does not require a c wire to function. While a c wire is not required, it is recommended as it provides a more reliable connection and allows the thermostat to communicate with other devices in your home.
20 Best Smart Thermostat Without C Wire

Very good value. Appeared to be new in box. Very easy install. I had a little trouble at first pairing it with my iPhone. Then I figured out all that was needed was to do a Firmware Update. I have been using it for only a week but so far so good.
1 big reason I chose the lux t-stat was for the adjustable Swing. I had a Honeywell and it seemed like you would walk by it and would turn on. I have had lux in the past and had good luck.
Thermostats are not complicated to replace. This thermostat isn’t either but there is a but. Assuming you have a new house our furnace you may not need to worry. This thermostat does not have a battery for power or backup and used the C wire (black or blue wire on t-stat) for its power.
So you should have 5 wires going to your thermostat, red, yellow, green, white, and blue/black, you may also have two red wires depending on your setup. If you have 4 wires, this unit comes with an adapter that you have to hook up to the furnace then to the t-stat wiring.
Its not difficult and the book tells you what to do or technical support is very helpful with this also but not everyone is going to want to crawl into their attic or wherever their furnace is at. Just because your C wire is behind the t-stat doesn’t mean it is connected to your furnace.
This was my issue and required rewiring at the furnace to make the t-stat work properly. So it took a 5 minute project take a few hours. Once everything was hooked up, the fan was on. Downloaded the app, and was able to control everything from that.
Not sure if it defaults to turn the fan on but just a FYI if it happens to you. It is nice to be able to control from my phone so if I am away or to lazy to change the temp. You can still control by the knob on the front.
You can also program a schedule and lock the thermostat from sticky fingers trying to change the temp. No fees associated with the app. I think this will help say some money in the summer time and can always be removed and taken to a new home.
I was a bit nervous about buying this Kono Lux, but after few research and clicks on the web, I went ahead! It has been three weeks and counting, I have never experienced any issue. Set up was way smoother than I expected – (I watched many youtube video on how to set it up before and while I was installing the unit).
If you follow the instruction carefully, there will be no issue. The thermostat unit needs to be a lot more firm with its wall frame, – my old Honeywell thermostat requires a lot more effort to remove than this Kono Lux.
It can literally come-off with no effort while holding it – this happens many times while I was going through the installation and setup process, but its firm enough to stay as long as you do not touch it.
The best part is. I can ask Alexa to adjust house temperature without lifting a finger!.
Smart Room Sensors help you experience the right temperature in the right rooms. When paired with the T9 Smart Thermostat, sensors let you prioritize living areas during the day and bedrooms at night for comfort where you want it, when you need it.
Adjust your thermostat from anywhere, or let the home react to your schedule with geofencing. Smart alerts let you know if the home is too hot or too cold. Balance the temperature of multiple rooms, creating a more comfortable home.
With people detection, Smart Room Sensors can know when a room becomes occupied, automatically adjusting the room’s temperature when you enter. The T9 Smart Thermostat’s simple, sharp touch display allows you to scroll menus right on the thermostat, personalizing your controls.
The T9 Smart Thermostat is easy to install yourself, especially with Honeywell Home support available. Its CWire solution also means it’s compatible with most homes.

Reviews From Real Customers
I had previously owned the Honeywell T5 Smart Thermostat and was happy with how it operated for the most part for a number of years. When it started to have some connectivity issues I decided it was time to upgrade.
I debated getting the “Amazon Smart Thermostat” since it was created by Honeywell, and the price was good, but I was swayed over the to the T9 because of some the Amazon Thermostat limitations, and I liked some of the additional features the T9 has.
First off if you are upgrading from any of the Honeywell T-Series thermostats (or the Amazon one for that matter) the wall plate is exactly the same so you just unplug the old one and plug the new one in.
in my house I have a radiant heat boiler for heating, and a forced draft AC. So basically two separate systems for heating a cooling. The T9 not only is able to combine them in a single thermostat, but it is able to understand that the blower fan should not come on when the heater is working.
Also during the set up it verified if it was a hot water or steam heat system. That was a first for any of my thermostats past or present. Setting the thermostat up is pretty straight forward. It connected to my wireless (2,4Ghz) just fine, even though I have a mesh WiFi network, and that is not always the case with many devices that require 2.
4Ghz). It also completed the set up BEFORE it performed a software upgrade. So I did not have a three minute pause in the middle waiting for software updates. I already had the Honeywell home application on my cellphone, so adding the new thermostat to my account was a breeze.
It would have been nice if there was a way to clone my schedule over from the old one, but that is not really a big deal. Overall it works great and looks nice on the wall, and so far I am not having any of the connectivity issues that showed up on the T5.
Other thoughts: – I appreciate that you can use the thermostat to perform a majority of the settings instead of being forced to use the phone app like a lot of other units like the Nest line. Exceptions being things like Geofencing that is tied to the cell phone, or Honeywell account settings.
– The display is bright by default. I mean really bright. I ended up turning my non-active display all the way down to 10% (from 70%) and the sleep mode to 0% at night since there is no reason for it to light up the room after 9:30 at night if you are not interacting with it.
– Alexa works great with the T9, and if you have remote sensors, you ask Alexa the temp in the individual rooms you have them installed. – If you use the remote sensors you can prioritize the heating an cooling a few different ways such as the average temp in you select it to throughout the house, the temp in the room you have sensors if it detects movement, or you can pick one sensor and make it the room that the thermostat uses to manage it’s heating and cooling.
If you have multiple people living in the house, you will need everyone to have the app installed if you want to use Geofencing properly, or else the one phone you have it installed on, will control the home/away mode.
Overall, this smart thermostat works well. With the optional additional temperature sensors that can be placed around the house, I am able to program the thermostat to respond to temperature in different areas of my two story home depending on the time of day.
The upstairs is always warmer than the downstairs, but I can have the control respond to the downstairs temperature during the day and the upstairs temperature at night. I can also program the A/C fan to run on call, intermittently, or continuously – something I was not able to do with my previous smart thermostat.
That helps even out the temperature across the two stories as I transition from day to night. The reason for 4 stars instead of 5 is that the interface on the app and on the thermostat itself needs some improvement.
The app always shows the main thermostat on the first screen instead of the sensor that it is using to control the AC. You have to click through two screens to see all the sensors. It has 4 default schedule blocks that you can’t rename (but you can disable), but you can add your own additional schedule blocks.
The thermostat itself shows the set temperature. You have to touch it to see the actual temperature. Otherwise, it works great and has all the standard features of other smart thermostats. Temps reported on the main unit and the sensor seem to be accurate to within 1 degree of a bulb thermometer.
I installed it myself, but had to add the C wire, so it took about an hour overall. I’ve had it a month now, and am satisfied overall. I haven’t tried the geofencing, and so far it’s just been doing cooling (no heating).
I’ve also used the vacation setting, and was able to check on the temperatures in house while I was across the country.
My system: Geothermal Heat Pump with Energy Recovery Ventilator and electric Aux heat This is a very good thermostat, but the reason I can’t give it five stars is because the built in temperature differential (1.
5 degrees F) and cycle rate are not quite adequate for a geothermal system. I appreciate that you can select a geothermal system in the settings, but it seems like the cycle rate is about 3 times per hour when selected.
It should be less. Here’s why: Geothermal systems take a lot of time to heat up/cool down when the system turns on. In heat mode, for instance, it may take 10-12 minutes for the output air to go from 70 degrees to 100 degrees.
If the thermostat only stays on for 7 or 8 minutes, it never achieves maximum efficiency. And no one buys a geothermal system unless they want maximum efficiency. With short cycle times on a geothermal system, you are taking an incredibly efficient and expensive heat pump system and running it at 50% efficiency.
For Geothermal heat pumps, the thermostat should keep the system on for at least 15 minutes. At a minimum, the user should be able to select a higher temperature differential (up to 3. 5 degrees?) manually, or a minimum on or off time, or a lower cycle rate.
This could be a simple software update for existing thermostats. For most systems, the default settings on this thermostat are perfectly sufficient. But for Geothermal, it would be nice to have the option to change them.
That would make the T9 thermostat 5 stars for sure. Please update the software with these options for geothermal heat pumps!.

It works as advertised. Installation straightforward, but you will need to add a C-wire if you don’t have one already—not a big issue if you have an extra wire in your cable in the wall. The user interface is clean and easy to navigate.
The scheduling is sufficient for me, but it is limited to 4 intervals max, some people might want more. The weird thing is that both the temperature measurement and humidity measurements were significantly wrong, temperature by 2 deg and humidity by a whopping 12%.
I checked this with three other temps/hygrometers, and the Honeywell was definitely in error. Since measuring temp and humidity would seem to be the most basic and important functions of a thermostat, you would think they would be accurate out of the box.
Talked to support about it, and they said the unit must be defective. The only option they had to replace it was return to purchaser, which since I bought it online from my utility was very inconvenient.
They should have direct warranty replacement. I subsequently found by reading the manual that there are offsets in the advanced settings which can be set to calibrate the temp/humidity, so that is what I did, although the offset I had to use for humidity was the max available at 12%.
Scheduling functions as advertised, and it does have the option to “anticipate” to pre-cool or pre-heat to get to the target temp you set by the target time. Connection to WiFi was straightforward, and the iOS app is fine, although it doesn’t include all the functionality that you can get using a PC, such as setting alert limits and notifications.
Curiously, sometimes the remote display on the phone does not match the actual thermostat—apparently it only updates at some pre-set interval, and sometimes they are out of synch. Overall, I think it’s pretty good, but I am taken aback by the poor temp/humidity measurement and the lackluster warranty support arrangements.
I will keep it, but if I was starting from scratch, I think I would consider other options.
I guess I didn’t do enough homework when I was looking at smart thermostats. What I was hoping to get was the ability to also use it as a remote thermometer in my garage where I have it installed. However, I found out that, for reasons I don’t entirely understand the thermostat thermometer will not show below 35 degrees.
I understand not being able to set it below 35, but I don’t understand not being able see the actual temperature of the space below 35. There are times where I’d like to turn off my heater and know how cold is in the detached garage.
However I was told that the thermostat won’t work right below that temperature. However, that doesn’t make sense and is demonstrably not true, as when it is well below 35 in the garage, the thermostat will run the furnace just fine until it reaches the set point.
Also, there are alerts in MyTotalConnectComfort which are basically useless because of this, as I can set alerts to tell me when the temp drops below 35, but the thermostat will never actually go below 35 to send me the alert, which is not at all useful to me.
I would also love the ability schedule my thermostat to be off and from what I can tell from reading around forums on the internet, a lot of other people would love this too. I understand there are situations where this would cause huge problems, like in a house, but there are plenty of other scenarios, like detached garages and shops where this makes perfect sense and doesn’t seem to be possible with any smart thermostat on the market, which is pretty frustrating.
Overall, this thermostat is decent at what it says it will do. The touch screen isn’t terribly responsive, but I pretty much run it through the app. It’s nice to have the outside temp and forecast. It’s easy to read from far away.
Nice to be able to change colors. Really, though, would love to have the ability to see the actual temp below 35 if furnace is off and also the ability to schedule heat “off” times and not just down to 40 degrees.
Even better would be the ability to set a low limit to turn it back on if it drops below say 20 degrees, or some temp I can pick.
I purchased two of these. After returning the first because the room temperature was off by between 2-4 degrees compared to my old 1980’s Honeywell thermostat. The Honeywell tech said that it was because the new thermostat measures both ambient and radiant heat.
This answer didn’t help me with the thermostat going on or off when I want it to. I returned it and replaced with the same model to test. The new thermostat was spot on with my control thermostat. Clearly the first was defective.
The heating season has just started and I am now having a different issue with the new thermostat. I set the temp for 72 with a room temp of 69. The boiler kicked in as it should and ran continuously for about 30 minutes when I noticed it seemed warmer than 72 in the house.
I checked the thermostat and it read 72. I checked my control thermometer and it read 75. I went to the basement to check the boiler and the high pressure releif valve on the system was releasing water.
The pressure in the system was over 30psi. I changed the thermostat setting from 72 to 71, the boiler turned off as it should but then something strange happened. The the room temperature reading on the new wifi thermostat immediately jumped from 72 to 74 degrees.
What’s up with that? Clearly there is something wrong with these thermostats. Either the temperature sensor, the algorithm, or both. My guess is that because the wifi thermostat creates its own heat (approximately 10 degrees warmer than the wall it is attached to when measured using an infrared thermometer), there must be an issue with the algorithm used in conjunction with the temp sensor to compensate for the heat generated by the thermostat causing the temp reading to be sticky and jump around.
My 1980’s Honeywell Cronotherm thermostat still works perfectly after 40 years. I only took it down because I wanted to update the look and have wifi capability. Its going back on the wall until I can figure something else out.
Enjoy smart temperature control at home or office with this T9 smart thermostat. An intuitive color graphical LCD touch screen gives you control over settings, while smart sensors installed in every room help monitor conditions and relay information to the central unit.
This T9 smart thermostat is compatible with most smartphones and tablets.
Two days after installing my T9 thermostat and two remote sensors, Resideo pushed down new firmware that caused “a limited number of devices” to revert to the factory defaults, and require a complete setup as if it was new out of the box.
Unfortunately, mine was one of those affected. I got it reconfigured, but the next day it displayed a “Memory Error”, and said I should contact customer service for replacement. I did that, but was told to clear the error, reset the remote sensors, and to turn off WiFi until new firmware was released.
It’s been over two weeks, and no new firmware has been released. While the thermostat and remote sensors are working using the daily schedule I setup, I can’t monitor or control the device using the app, the thermostat of course can’t access the Accuweather website for the local weather, and I had a very difficult time disabling geofencing and getting the time and date set in the thermostat after turning off WiFi.
While I very much liked the thermostat and it’s functionality for the two days it was working prior to new firmware download that broke it, I have been very disappointed with the length of time it has taken for Resideo to fix it! This isn’t rocket surgery, assign a couple of coders to it and get it fixed! At this point, the thermostat has been kneecapped to only performing it’s most basic function, which is controlling the temperature.
I could reinstall the old thermostat and have the same thing. This was not an inexpensive device with its two remote sensors, and at this point I have none of the advanced functions that I bought it for.
The broken firmware should have been fixed by now, or my thermostat should have been replaced.
Our first smart/wifi thermostat (also Honeywell) stopped working (repeatedly reset/rebooted and inside temperature readings were way off) after about 7 years, 2 years after it moved with us to our current home.
We picked up a T9 to replace it since that was the model I’d been considering when we moved had we left the old thermostat behind. The remote temperature sensors are a nice improvement which we have in the bedrooms to keep them more comfortable at night (before that the bedrooms dropped about 4 degrees below the living area where the thermostat was located).
Aside from the remote sensors and cleaner/modernized UI not a huge difference from the old landscape orientation thermostat. I kind of miss having all the information visible without tapping the screen (just the indoor temperature and some oudoor weather icon I think show most the time).
We’ve only had it a few weeks now and I haven’t gone through every setting to see if that is configurable; I definitely want to go in and dim the display. Some minor wifi connection issues with our Eero mesh, but I expect that will be worked out eventually on the router end.
It’s dropped connection twice so far, but connected on it’s own again. One time it didn’t connect right away so I had to manually set up the date/time on the thermostat for it to continue working offline, apparently it doesn’t remember the last date/time it had when last online.
The app/programming is pretty intuitive for the most part. My only complaint is that it isn’t always clear when changing the schedule for a single day, will also change make the same change on other days.
I worked around that problem by adding custom time ranges on weekend to have the later wake and up times without affecting weekdays.

It reads temperature and movement in whatever room it is placed in for complete home monitoring and energy savings (SmartSensor sold separately).
One difference between the Premium thermostat enhanced thermostat is the air quality monitor. The thermostat is fine. The air quality monitor is mostly useless. TL;DR: save your money, don’t buy the “premium thermostat” for the air quality sensor.
It has two problems: 1) It measures only volatile organic compounds. If you’re astute, you’ll see that ecobee infers CO2 concentration based on an average correlation from human breath or something. This is a fancy way of saying they take one number, and then it multiplies and divides and adds and subtracts to get another number.
(It may be a nonlinear transformation, but it’s still just a deterministic transformation. ) Imagine if Ecobee marketed separate measurements of Fahrenheit and Celcius using “the average correlation between the two measures on the surface of the earth.
” Even if literally true, it’s a fancy way of saying that they derive two numbers from one number. (My day job is a statistician. Most of statistics is to take many numbers and reduce it to fewer numbers.
This is doing the opposite. ) 2) The sensor is a relative sensor. Ecobee admits to this. This in itself is not bad–even your alcohol thermometer that you measure fevers is a relative sensor–the key difference is that your alcohol thermometer is calibrated.
The Ecobee air quality sensor is both not calibrated and worst of all, the calibration changes, so it’s impossible to infer when your house is relatively polluted. What this means in practice is that when I open the window, the sensor shows “Clean” and when I close it, it shows “Poor.
” During humid east coast summers when opening a window would let in a lot of humidity, “Poor” changes into “Fair” into “Clean” over the course of several weeks. If you open a window for a few hours and then close it, it immediately goes back to “Poor.
” Ecobee technical support suggested that I expose the sensor to indoor air pollutants. I’ve done this with all the detergents I could possibly find in my house. Nothing changes. “Poor” air quality stays “Poor.

1. It is difficult to setup and troubleshoot since some settings are only available on a person’s web account, others only on the phone app, and still others only on the device itself. Why aren’t all settings available in one place, preferably the phone app? 2.
The device display is confusing. It appears to show the heating range but actually it is a combination of the heating and cooling temps in one graphic. This information is not useful. It would be better to have the info in two separate ranges, maybe showing only the applicable range; such as the heating temperature range when the furnace is being used or the cooling temperature range when the air conditioner is being used.
3. Finding answers to questions and problems is difficult. A good source would naturally be a searchable user’s manual available through the app but it is not easy to find or use. I couldn’t figure out why my furnace was overheating the house to 85°F in the middle of the night.
Turns out, an extra sensor accidentally fell into the garbage and was taken out with the trash. Since the Ecobee averages temps among sensors, it was averaging the outside and inside temps and trying to heat up the house since it was cold outside.
I had to figure out this on my own since I couldn’t get assistance online or from the app. Overall this could be a nice piece of equipment but it isn’t terribly user-friendly and help isn’t easy to find.
Amazon Smart Thermostat is ENERGY STAR certified. Easily switch your traditional thermostat and help reduce energy usage. For on-the-go comfort, let Alexa set the temperature, or set it yourself from anywhere with the Alexa app.
Amazon Smart Thermostat is compatible with most 24V HVAC systems (like conventional force air, heat pump, radiant boilers, etc). It does not work with 110-240V HVAC systems (like electric baseboard heat).
Smart Thermostats require a C-wire (most homes have one) or a C-wire adapter kit (sold separately). Guided installation instructions are included in the Alexa app, and will walk you through checking for a C-wire or options for powering your thermostat.
The Amazon Smart thermostat is a simple, modern looking unit that is setup through step-by-step guidance on the Alexa app. It’s priced well and the remote connectivity seems to work great, which was my main purpose of purchasing.
A $50 rebate was available through electric company making this almost free. Two things that were not perfect for me. One is my fault. Pay attention to the wiring on your current thermostat and understand if you have a heat pump or other non-conventional setups as sometimes old units use the same terminal for more than one thing.
The second seems to be a lack in design features at this point and that’s related to the ‘hunches’ that would allow the thermostat to be smart. I am not the only one living in the house but it was only reacting to away when I was gone.
That’s fine except when another person is home and the temp auto bumps up to our away warmer A/C setting. It also didn’t seem to pickup on sleep very well, which is when we like it cooler. Until the features are improved, we will just use it as a dummy thermostat with a schedule, and continue trying to save some money by bumping up when away but with the luxury of turning back to “home” temp before returning home.
Just purchased (great price!) and installed the Amazon Smart Thermostat and regrettably will un-install it. Firstly, I question how smart it is in that you need the Alexa app to do anything. It appears the thermostat gets dumb if I uninstall the app after setting the thermostat up.
More importantly, however, is the designer/s of the thermostat failed to consider a separate power source for the C-wire. I have 2 wires going to the thermostat. one from the heater control board and one to a 24 volt power transformer.
Wire from control is pretty straight forward but there are no instructions or guidelines for the wire from the transformer. If you follow the instructions explicitly, the thermostat will NOT be powered by simply connecting transformer wire to C-terminal.
the second wire of the transformer NEEDS to be connected to the RC terminal to power the thermostat. To do this, you need to lower the small switch to expose RC connection. In doing so, you disconnect the ability of the thermostat to control the AC unit.
Not a good design!Additionally, the Alexa app is not intuitive regarding setting a schedule. Finally, I could find no place to HOLD a temperature setting if I was to be away for several days. SignedDisappointed.

The installation instructions for homeowners who already have 5 wire systems are straightforward, a very easy installation. However, if you have an older 4 wire system that supports the old Honeywell round thermostat or a thermostat that is battery operated, you may need an electrician to install this thermostat.
TBF, the site indicates a “C” wire requirement, typical of 5 wire systems (who knew?). Since my electrician wanted $800 to fish a new 5 wire and install the required 24v transformer, I told him to get lost and went to YouTube for advice on using 4 wire with a 5 wire thermostat.
There are a couple of extremely helpful videos, with a simple workaround that facilitated the install. I did lose some functionality since I can no longer control the fan motor separately from the heat or A/C control, definitely not a show-stopper.
The burner control unit already had a 24v transformer installed, so I was good to go with the workaround. With the thermostat successfully installed, the device is very handy and easy to program, both on-screen and viable the downloadable app.
I can’t wait to try out the Alexa functionality. Not only would I recommend this thermostat, but I am also purchasing a second unit today for another zone.
With any Wi-Fi enabled technology, it’s equally as important to include the app in your rating since after all, that’s probably half the reason you purchased the product. I am not going to lie, I’m pretty disappointed in my purchase.
The hardware itself is perfectly fine. The screen is a bit smaller than I’d like but aside from that, it functions as it should, setup was relatively easy and it does its job just as well as my last Honeywell thermostat.
The app however, is extremely outdated and has little to no features. I was expecting to see, at minimum, analytics regarding usage and run time. An added bonus would be the ability to enter details about your AC system which the app could then compute estimated energy usage, and more.
Overall, the only difference between this thermostat and the Honeywell I had prior is; 1. Shows relative humidity. 2. Shows outside temperature and 3. I can now turn the temperature up or down while sitting on the couch rather than having to stand up and walk 2 feet.
In my opinion, not worth $170 just so I can be lazy.
The Honeywell 9000 is a nice looking wifi thermostat but in my opinion it’s much more complicated than it needs to be. The LCD itself is quite nice but it never dims. For us that’s fine because it’s in a hallway.
For others this could be a problem. My biggest issue is when adjusting the temperature while in Hold mode you always have to “confirm” your change(s) by pressing the Done button. In general it always asks you to confirm inputs.
Why? Just let me change it (the phone App requires the same confirmations). They have a Vacation mode – but it requires you to enter the dates you’re going to be gone. Why? Just let me enter an “Away” mode with a Cool temp and a Heat temp.
People change their vacation dates all the time but once you leave your house (after putting it into Vacation mode) the dates can’t be modifed from the App. The theromostat does everything I need it to but they’ve made the interface more complicated than it should be.
The phone App is okay and generally lets you do normal day changes (but will not let you enter vacation mode). They should really spend some time looking at the Lennox thermostat and associated Phone App – much cleaner, simpler to use and yet has more functionality.
Ecobee’s Smart Thermostat Premium is brilliant at savings and comfort, allowing you to optimize your energy use through superior intelligence and technology. Included SmartSensor eliminates hot and cold spots and adjusts the temperature in the rooms that matter most.
A built-in air quality monitor, smoke alarm detection, and geofencing technology to understand occupancy are just a few of the features that make saving energy just the beginning. *Apple home hub required to enable Siri.

I bought 2 Honeywell Thermostats and the first one I bought was able to function my A/C when it was installed it but, when winter came, my heating wasn’t kicking in. I bought another Honeywell thermostat and the same problem occurred.
My home didn’t have the C wire that caused the issue for both thermostats not to work. Had to put the original thermostat back on. My furnace was working fine for winter and when I switched to A/C mode, it wasn’t kicking in.
My HVAC guy didn’t rewire the thermostat correctly and I was losing it!!! The summer has been brutally hot over the last 2 weeks. I saw the Google Nest Thermostat on sale and before I decided to purchase it, I watched some videos that inspired me to try and install this device on my own.
I also bought the trim kit and performed a DIY. I missed a step when I snapped the the thermostat to the base as I wasn’t seeing any power to the thermostat. I didn’t realize there were 2 batteries that needed my attention where I had to remove a sticker.
Once the thermostat powered up, I followed the instructions and it conducted a test. I heard my A/C compressor kicking in and my furnace fan going on. The Wi-Fi connection was also a success and I was jumping for joy!!! It’s amazing that I’m also able to control the temperature anywhere from my mobile device and that it goes into eco mode when nobody is home with presence sensing.
I regret not buying this thermostat a few years back. It’s pure brilliance and I’m loving it!!!.
Very happy with the performance of the device and the interaction with my smart home ecosystem. Price is high, but with the rebates from my town and state, it isn’t much more than a typical thermostat.
The main downside for us was two issues: 1 – we don’t have a common wire in the locations our thermostats are located and can’t use the adapter sold separately, so we had to pay an electrician to run new wire.
The only reason for a common wire is to power the more hungry Nest. Not sure why they couldn’t just include a rechargable battery or even have one as an add-on. 2- We have radiant hydronic floor heating in one room and this Nest is not compatible with the Tekmar control system which regulates that room.
While I realize these are different brands and compatibility is not required, it would be nice if they could work a software patch that would allow the Nest to interact. The patch could be sold for a reasonable price with the proceeds getting split between the manufacturers.
One other annoyance is we wish we could set each thermostat to respond to individuals not being home. Currently if everyone isn’t home, it will go into ECO mode and stop heating/cooling according to the temperature range you set.
However, my teenage daughter has her own thermostat and it would be great if that one thermostat would shutoff the system when she left for work or school.
I installed the Nest about a year ago and it worked fine, up until three weeks ago when it would short cycle my AC. My AC unit would click on and off constantly, sometimes it would turn on and be fine other times it would continue the short starting pattern.
When my AC repair person came out, he told me Nest are only good for about a year – two years, then something like the issue I am having will happen. I thought he had an axe to grind with Nest so I shrugged off his comment and stuck with the Nest after he did his routine maintenance.
It worked or about two weeks and then the issue came back. I decided to put my old thermostat back on and it worked, no problems. For anyone wondering, I had all the proper wires, it was running 27 volts, no coolant leaks, and the coils weren’t frozen.
The issue was the Nest. I contacted customer service and they told me that I wasn’t eligible for a refund but they would send me a base replacement unit. Maybe that would solve the problem, but should a thermostat really only be good for two years? What if this happened during a snow storm? What a liability this could be for them.
I’m disappointed in Nest as I had hoped for a better outcome but just another example of a bigger company getting away with a poorly made product. I know Nest’s are trendy but please save the 200 dollars and go with another system.
The Wi-Fi 7-Day Programmable Thermostat connects to your home’s Wi-Fi connection to give you remote access from any Wi-Fi-enabled device. You can also download the free app to your smartphone or tablet for virtual access to your thermostat.
From your connected device, you can program for comfort and energy savings. Additionally, you can access the thermostat’s functions using the large, easy-to-read display.
This review is for the RTH6580WF1001/W. After purchasing and setting up two of these, I’m convinced most of the complaints here are people that don’t read the manual. For example, one user said they were frustrated about how the set point has a delay built in.
That is a setting in some installer menus that is described in the accompanying manual and easy to turn off. Connecting to my Wifi was a breeze for me and only took a couple minutes for each one. The remote connectivity is great and you can set the whole schedule on the app, for all 7 days and each interval setting, which is way easier than stepping through that on a thermostat’s physical interface.
I like that this looks like a more typical thermostat. I’m not for the crazy hi tech looking ones, despite being a high tech person. I just want a more traditional looking thermostat. The other thing I really like is that these don’t have any batteries.
It gets its power from the furnace, which does require you to have a common/C wire from the furnace. Never having to replace batteries again is a minor but refreshing feature. If power goes out, your furnace doesn’t work anyway.
Once power is restored, it uses a stored set point until it can establish a Wifi connection, then synchronizes with internet time and begins using your schedule. This was good to see happen, as when you initially configure, it asks you to set the time, which led me to believe it may not synchronize time when lower is restored.
I bought this specific Wifi thermostat because my existing non-Wifi thermostat looked almost identical and I assumed that would make physical installation easier. I was correct, this Wifi model snapped right onto my existing wall plate and worked great.
Zero additional wiring. Problem is, all the time I saved with installation was lost during set-up. Setting this up with my home Wifi was a NIGHTMARE and I work with computer systems daily. Took me two hours to figure out (while in the cue waiting for a customer service rep on the phone.
never got to talk to one) but I finally figured it out. Took 20 attempts but it finally registered with my laptop and I was able to get the setup page to finally load so I could carry on. UGH. And now that it’s all set up and working, I’ve noticed that the sensor in the thermostat is reading at least 2 degrees colder than ambient temp, verified with other digital instruments in the same hallway.
So now, mentally I have to remember that this one reads low and account for that when setting temperatures in my home zoning system up. UGH. I expected better for $70 bucks on sale! OH, and there’s no battery backup!.
I bought a vacation rental about a 13 hour drive from my home and wanted a way to ensure I had control of the thermostat. I purchased this and had it installed in the house I live in for about a month.
Everything worked great. I moved to the rental location and after resetting the WIFI configuration, it connected right away and now I can control everything from my phone. The app connects within a few seconds and provides me with the information I would expect.
I can turn the furnace on or off while sitting in my house so far away. A couple of notes, if you move this to a different network you will need to reset the WIFI configuration on the T-Stat. I didn’t see any instructions in the box on how to do this, so I had to go the help section of the Honeywell Home site to figure that out.
Also, the furnace I moved this to did not have a C-wire however I used the provided jumper and rewired the terminals on the furnace and it worked just fine. However, when you do this you lose the option to run the fan by itself.
Not terrible but not great. That is a furnace issue, not a T-stat issue.

I just finished reading the reviews for this product because I was wondering if it was for the same model that I own. If I’m not mistaken and if the reviews are in fact for the RTH9580WF1005 model, then there must be a reason.
But anyway, I was trying to figure out why people would under-rate this thermostat which I have owned now for 8 years without any problems. The only thing that I keep seeing is that most people did not install this themselves.
I know people said they hired HVAC pros to do it for them and I could have done the same, but I always remember that if I do something myself with the help of a video guide, it always comes out better because I actually care about the job being completed correctly.
I’m not by any means a handyman, electrician, let alone an HVAC pro, but I can follow video instructions and they are pretty straight forward. I’m very happy with this product, I would recommend it any day, I would buy it again and I love the ease of use both on the actual unit and via the smartphone application.
I chose this model back when other companies were making other products that have a more modern look. But I liked all of the extra information that this model displays for you versus the lack of information you get from the other companies.
The RTH9580WF1005 doesn’t seem to be manufactured anymore, but I think Honeywell makes an updated version now. I’m sure its a solid product since Honeywell has been in this game since apparently 1906 and the other guys just started after the turn of the last century! The only thing that I wish that this particular model had was Apple HomeKit compatibility.
I believe the newer models include it now so I’m not going to knock it for that. Other than that, it gets 5 stars from me.
Our home is 15 years old and has 4 heat pumps. One of our old thermostats failed and I saw this Honeywell touchscreen smart thermostat online. Such a good price I decided to buy 3. I’m reasonably handy, but no knowledge of hvac.
It took 30 minutes to install the first unit. 15 minutes each for the other 2. WiFi pairing was simple. I was very impressed with the features and the ease of use. After a month I bought another one for my cabin! Cabin installation was a little more complicated because it had no common wire, I had to go back the the air handler and hook it up.
But the process was entirely workable. Now my wife and I can check the status of my home units and my cabin unit and control all with my phone from anywhere. in a snap. It is especially great for the cabin as it is frequently loaned to friends and family.
I can periodically check to make sure thermostat properly adjusted when they leave. The units at my home have been installed for 2 months. I have had zero issues. They work perfectly. I highly recommend this product.
This is a great device and I highly recommend this unit**** BUT the instructions tell the owner that automatic updates occur using the red-link Wi-Fi router. THIS is not true. Honeywell no longer uses the Wi-Fi for updates.
You have to download the update and save it to your computer and then download the update to the thermostat. IF You download this update do not rename it, so you can easily find it. You must keep the same document name for the thermostat to download it.
The thumb drive location on the thermostat is on the bottom front edge of the display, the thermostat must remain attached to the backing plate. You can find the URL address on the web. good luck.
This easy-to-install smart thermostat helps save on energy costs by allowing you to control and schedule the temperature of your home anywhere through the Nest app. The clean, frosted display blends in nicely with the surroundings, lighting up the temperature as you approach and disappearing when you walk away.
This seems to be the one Nest thermostat that doesn’t have the C wire issue like the previous one I bought had. I have an older heating system (35 years old) that doesn’t have a common wire. I tried the Google Nest power connector to simulate a C wire and I couldn’t get it to work.
So back it went. I was thinking of using Google’s recommended HVAC company, but after talking to my normal HVAC guy he mentioned that Nest had a later generation thermostat that didn’t require a C wire.
I googled smart thermostats that don’t have the C wire issue; found this one on a blog and Walmart had the cheapest price on it. Works much better and no C wire issues like on the previous one. For example, I noticed on my previous Nest thermostat, the display didn’t come on upon approaching it.
On this one, it works correctly. The overall fit and finish on this one is superior to the older cheaper one I bought from my gas company. As is so often the case, it pays to spend a little more money to get the product that works right.
DON’T BUY THIS!!! Definely not even worth one star based on my experience! The product was so bad out of the gate. It didn’t work upon arrival. After countless hours with their India support team, still couldn’t get it to work.
Finally after hours of frustration, we determined the replacement base was defective. So I got a replacement. Problem still not over. The replacement had a defective faceplate. in order to make it work, I had to use one working base and a faceplate from the first device.
So then, after properly installing it, I realized product’s wifi doesn’t work. The app will not connect. After year the faceplate is now not charging anymore. I called support so any times I’ve stopped trying.
I have reset this product at least 50 times since I’ve owned it. Otherwise I’m left without an AC and I live in hot weather. Just a complete failure of a product. I had a Honeywell $30 thermostat in here for 12 years that worked like clockwork before this garbage Google product.
I’m not surprised to see so many one star reviews. I imagine they’d all be ZERO stars if Google allowed it. The product absolutely sucks.
Called today to try and get support or help for this. After an update, it just stopped working. It only has a white screen. Support determined that it is “broken”. Support suggested I try to contact the store I bought it from to obtain a purchase date.
I am not sure exactly when I bought it. If it is over 2 years ago I was basically told I wasted my money. SO if this is 3 years old— Google says “oh well it’s broken and by the way, you can’t just buy the screen you have to replace the whole thermostat.
“The expected lifetime of this unit was at least 10 years, but 2 to 3 years in it can fail and Google has no support or help for a customer. I know the company doesn’t care. But if you are considering trying the nest thermostat because you believed, like me, it would be easy or save you money then look at other devices.

I absolutely hate Google thermostat!!!! It was installed in the apartment units where I live and I know it is only there to spy on people, hence “GOOGLE”, but not only that-it CONTROLS when it shuts off and comes on!!! I DON’T appreciate that!!!!! Who are you to turn the heater on when I don’t want it on??!!! I have ASTHMA and HEAT exacerbates my condition!!!! And when I turn the thermostat to a certain temperature for the A/C, GOOGLE turns it up or off!!!!! So then it gets HOT in my apartment!!! Then Google will turn it on early in the morning when I don’t want it on because it’s NOT hot enough, now I’m TOO cold -when I NEEDED it on at night to sleep BETTER!!! I had to reset it a couple of times, but Google STILL HAS CONTROL and I WISH I CAN SUE THEM for making my ASTHMA WORSE and making me UNCOMFORTABLE in my living space!!!! Who are you to turn the A/C off a few minutes later after I turn it on??!!! UGH!!!!😡 I want the thermostat that I CAN CONTROL !!!!!! I ABSOLUTELY HATE GOOGLE THERMOSTAT!!!!!!!! Let’s see if you KEEP this review “on/up” since you have ALL the CONTROL!!!!🤬😰🤒.
I purchased this thermostat after buying a new home. I had one previously in a condo and it worked well enough for what I needed then in a tiny home. I enjoy the features of being able to change the temperature from my phone.
It’s been useful when coming home from a long trip and being able to have my house cooled before arriving or even changing the temperature from another part of the house. However, I honestly have come to HATE these Nest thermostats.
I have owned the original Nest as well as three of these models. I purchased two of these in October of 2020 to replace our upstairs and downstairs thermostats. By January 2021, the upstairs thermostat would not connect to hardwired power and could only be charged with a micro USB.
It then dropped all WiFi communication which is the main reason I wanted the thermostat. I had to call Google and replace it under warranty. The downstairs unit was even more of a nightmare. I learned a long time ago that the “learning” feature is garbage for me and my family.
I had a simple schedule set up in the app. The thermostat stopped using the schedule and kept switching itself to eco mode even though I was always home and had all learning/eco settings switched off.
It constantly had a mind of its own and tried to change the temperature. It didn’t even recognize me as being home even though I had the location services settings enabled. I reset it, ensured the schedule was how I wanted it, etc.
but it did not respond. Now, the nest will only run the air conditioner at night and will not control the unit during the day. I got so frustrated with it, I ripped it out of the wall and re-installed the junky 20 year old thermostat that came with the house.
The only reason I give this unit 2 stars is for the WiFi/app features. I loved that. Other than those two things, Nest can pound sand and enjoy sitting in the landfill. Worthless and a waste of money.

I bought one from JL to replace a Drayton wireless thermostat which had controlled the boiler for 30 years. Why replace? Because I wanted to be able to programme the thermostat to control my new heat pump.
It looked the part but it didn’t work. I couldn’t get a satisfactory wireless connection to the heat link which controls the heat pump (or boiler). That seemed poor since the Drayton had never had a problem over that distance – it was 11m and the Nest is supposed to work up to 30m.
The Nest helpline instructed me that I had to mount the heat link at least 30cm from any structure including the junction box controlling the heat pump and the shelves on the wall as in the instructions.
The instructions only said 30cm of space from the boiler. Nevertheless another costly elctrician visit and the heat link was resited. But the wireless connection was still unsatisfactory. I had the choice of sending the Nest back or accepting that it wouldn’t work with the thermostat 11m away.
I decided to resite the thermostat into the room next door to the heat link and given that the distance now was less than a metre, it has worked perfectly. It controls the heat pump and is programmable.
Nest may say the 30m distance doesn’t take into account the number or thickness of the intervening walls, but having said that the much cheaper and reliable Drayton Digistat coped.
So this is what I experience with this device support. My head unit was not holding the charge, so I manually had to charge the head unit and run my thermostat. Then I contact this Google store Nest Thermostat support team and we did all kind of long hour technical troubleshooting, then they convinced that the head unit is defectives.
It was under warranty, so they agreed to replace it. they sent me the return label end of August 2022. but the weather and temperature at that time was not in favor for me to sent the head unit back, cause till I get my replacement head unit I will have no COLD or Hot air in my house, so I decide to wait till the weather condition is bit favorable and sent my head unit back to the store by September 20th.
Till today, it is September 27th 2022 did not receive my replacement head unit back. I am in contact with the team and they said another 5 business days to get some response from them. they also said they are escalating this issue and this 5 business days is there escalated SLA.
now my question to the community, which organization in the world rather than Google Nest had this 5 business days for Escalation SLA ? I did not experience this kind of SLA in my entire life so far.
Today I give up with my afford and decide to move on with another product, I guess I will learn something new form that company as well 🙂 just letting you people know, so that you guys can take the right decision before purchasing this product.

We bought one for our first home because the electric company was offering a rebate and we wanted to make our home a little smarter. We did like it, but beware that your local HVAC person hates these things.
It was easy enough to install that we did it ourselves with no issues. However, these do not use/require your “c” (common) wire. What does that mean? Instead of providing continual, low voltage power, without the common your system takes a big gulp of power when starting up your heating/cooling.
The ease of controls were nice and I liked that I could monitor and control the temperature from my phone (for my pets) while away at work. What I did NOT like was the “away” setting itself. Basing on your phones location, it goes into either eco or the minimum/maximum temperatures that you set but their is not a lot of leeway to choose those.
For example, we went on vacation so no one’s phone was near the house but we had the pets there and a sitter coming 3x a day to check on them. Our setting was 68 at all times. Because of “away” mode, the sitter informed us our thermostat was reading 80 now – no good, especially in Louisiana because of the heat and humidity! The system was working fine, it just sensed that we were away and wasnt running (trying to save energy?) to maintain temperature settings.
It would also start these “energy saving campaigns” on its own and ignore its settings and just stay at eco all the time at some times. It ended up adding a small bit value to our home when we sold the house, so thats a plus but we don’t necessarily miss it.
We didn’t see a significant amount of savings on our electricity. I would like to try another smart style thermostat in our new home but maybe not the smartest one that is programmed to outsmart you and thinks it knows best.
After having this device for about 7 months I can safely say that this device is not what it’s all cracked up to be. Aesthetically it looks really nice on my wall, gives it a pretty modern look. Also being able to control the climate via phone is pretty handy but other than that it’s not very useful.
First it’s auto scheduling is very unpredictable and impractical. As a person that already keeps the thermostat at 78 degrees there doesn’t seem to be anything this thing can do to save energy while also keeping the house at a comfortable temperature.
It will try to put the house a 83 degrees sometimes and you have to switch it back up. The auto scheduling will eventually switch it back down and it’s a constant fight with this device, which ends up using more power to cool the house 6 degrees.
If you try to set up your own schedule like turning down the AC during peak hours, it will make its own with worse temperatures at random times. At the end I have not seen a change in my electric bill compared to last years kWh usage after 7 months with me allowing it to auto schedule.
Despite the uncomfortable temperatures it set my house too. I ended up turning it off, which defeats the purpose then it just becomes a regular $30 thermostat for $250. Luckily my local electric company has a rebate program that gives you a $85 credit to your bill which brings down the price but not enough to justify the cost compared to my old thermostat.
Your better off just keeping your thermostat at 78 and just leaving it there because it’s more energy efficient to keep a house cool that to cool it down from a high temperature.
I bought this unit to upgrade from Gen 2 because it can both make use of the sensors and it has dual-band WiFi for a stronger signal. It was very easy to install, it looks great, and it’s very intuitive to use, either on the wall, with your phone, or via a voice assistant.
I’ll ding it a little bit because the sensor schedule—that is, when the device can be told to use which sensor—can’t be customized. You have 4 pre-set blocks to choose from, and that’s it. But then the trouble started.
First I got a dreaded W5 error, meaning it’s WiFi radio was no longer working. I contacted Google for a replacement, which arrived promptly… but it kept getting caught in a boot loop and I couldn’t set it up.
A second replacement arrived and wouldn’t correctly read my (very straightforward!) wiring, despite the fact that the one with the W5 error still could. The third replacement had the same issue, at which point I was advised to spend $130 to have a technician inspect my system to verify it was in fact the thermostat that wasn’t working.
So after 6 total hours on the phone with customer support and HVAC technicians, and 3 replacement thermostats, I finally got my fourth one: an ecobee. I had it on and functioning in 20 minutes. My experience is probably very far outside the norm.
I most likely just had a run of bad luck; I know when I see reviews like this for something I have maybe already talked myself into, I think, “ah but that’s just one guy; he’s unlucky or he did something wrong; that won’t happen to me.
” And it probably won’t! But given the sheer number of issues I encountered—from failing components to annoying limitations to inept and sometimes contradictory customer support (who, at the end of the day, are call-center employees and decidedly *not* HVAC technicians)—I’d urge you to strongly consider other smart thermostats.
This one is just not worth the risk or the headaches.
The Nest Learning Thermostat is a smart thermostat that learns your schedule and programs itself to help save energy. You can control it from anywhere with the Nest app, and it works with Alexa and Google Assistant so you can adjust the temperature with your voice.
And it’s beautifully designed, with a big, bright display and metal finishes to suit any home’s style. Remote control and mobile notifications require working internet and Wi-Fi. Alerts can notify you of a potential issue with eligible HVAC systems.
They’re meant to provide helpful information, not an endorsement or representation of any kind about the health of your HVAC system. Alerts aren’t intended to replace a diagnosis by a qualified HVAC professional.
Energy savings are not guaranteed and depend on energy usage, weather, and other factors. Voice control requires a compatible device, and working internet and Wi-Fi. Independent studies showed that Nest thermostats saved people an average of 10% to 12% on heating and 15% on cooling.
This thermostat looks nice, better than any other thermostat. The installation and general setup is OK, it takes about about 30 minutes if all wiring is there. It also easily integrates with Samsung SmartThings v2.
But the functionality is not as advanced as for instance Ecobee’s. The occupancy sensor in Nest thermostat is pretty much useless. I was home moving around, and the Nest thermostat would switch to Away state thinking that there is noone home.
The remote sensor that came with it does not have an occupancy detection, so all you can count on for occupancy detection is really the smartphones of the people that live in the house, which is not a really nice way of detecting home occupancy.
If you have multiple sensors in the house you only can pick one at the time to regulate on its measure temperature, there is no possibility of averaging in this thermostat. Also, the history view is really poor for Nest, Ecobee did a much better job on this.
And if you download the history data from the website, the status data is in JSON format and it is impossible to interpret. Also, the deadbands are not adjustable for Nest, at least I could not find it.
I did not try its learning feature myself since it already had a lot of negative comments. So, I think if one wants to buy a nice stylish looking thermostat for a very basic use, Nest Learning Thermostat is a very good choice.
But if one wants a highly customizable thermostat which one can also regularly monitor and adjust, then there are better choices , like Ecobee.

I love the ecobee smart thermostat premium. I can easily control on the touch screen, with my Alexa show products, and on the app. It offers personalized schedules allowing me to control when my unit needs to run more/less.
For example when on vacation, while at work. It also offers maintenance notifications and let’s me know when I need to change my filter or have my HVAC unit serviced, saving money on routine HAVC service calls.
I have a UV light for better air quality, this is the first system I have seen that notifies me when the UV light needs changed. I love that it shows my homes air quality, weather outside 4 days in advance.
It learns my perferred settings to ensure my home is always at a comfortable temperature without overworking my system. The smart sensor is a great addition as it allows you to control hot/cold spots throughout the home.
Ours is our master bedroom and I have noticed it now stays the same temperature throughout the home. It took my husband and I about an hour from start to finish to install the system. We do have an older home with a gas furnace and did not run into any issues while installing.
The ecobee smart thermostat premium gives you complete control over your home’s heat and air while keeping it easy to control from anywhere. Another great point is it being energy efficient, saving upto 26% annually on cost.
We upgraded from a plane Jane thermostat to this smart thermostat. It was easy to install and comparable to other smart thermostats on the market. The price was great compared to other smart thermostats.
It has a lot of features, and can be used to cut back on costs. However, it can be difficult to turn a lot of the extra off. This thermostat wasn’t triggering our aux heat to come on and it was making the unit run constantly.
Our heating and cooling guy recommended we return this thermostat and get a different one.
The reason I have to give this one star, is because I use this for a business. We have multiple offices, and so the app that goes with this was really appealing. Well the server/app doesn’t work a good amount of time.
And I know it’s actually ecobee, because I chat or call almost every time it happens (that I notice it), and they always tell me it’s their issue. Now normally it’s not that big of a deal. But during spring and fall, switching between heat and a/c is a regular occurrence where I live until we are in the winter or summer seasons.
Another reason I got these was so that employees weren’t constantly messing with it. But when the servers go down, and you can’t change anything remotely, it forces me to give someone the code so they can switch it.
And this has been a 3 year long issue. They have no intention on improving. If you’re using these in your own home, you probably wouldn’t even know how often the servers go down. But I still wouldn’t recommend this company to anyone.

If you don’t have a c wire, you can still use a smart thermostat, but you may not be able to use all of the features. For example, you may not be able to use features that require constant power, like some scheduling features or remote access.
