20 Best Smart Thermostat No C Wire (2022 Updated)

When you shop through links on our site, we may earn an affiliate commission. This educational content is not intended to be a substitute for professional advice.

A smart thermostat is a thermostat that can be controlled remotely via a smartphone or other device. Many smart thermostats also have additional features such as energy monitoring and automatic scheduling.

A “c-wire” is a common type of electrical wiring used for thermostats. It stands for “common wire” and provides a constant flow of electricity to the thermostat. Some older homes may not have a c-wire, which can make installing a smart thermostat more difficult.

However, there are a few different ways to work around this issue. One option is to use a battery-powered smart thermostat. Another option is to install a bridge device that can create a c-wire connection.

Conclusion

If your home doesn’t have a c-wire, you can still use a smart thermostat, but you may need to buy a battery-powered thermostat or use a thermostat that doesn’t require a c-wire. You can also install a c-wire yourself, but it’s important to note that this is a more complicated installation process.
