How to choose (and common mistakes)

When selecting a smart thermostat without a C-wire, first check your current system's compatibility. Many modern devices can work without a C-wire, but some may require additional adapters or power accessories. A common mistake is assuming all smart thermostats can operate without this wire. Also, consider the features you need, like remote access, learning capabilities, or energy reports. Don't forget to read reviews and check installation requirements to avoid surprises. Finally, ensure the thermostat you choose is user-friendly, as this will make adjusting settings much easier.
