What Makes Smart Thermostats So Smart?

The idea behind smart thermostats is that they can make heating or cooling our homes a more efficient process.
Because smart thermostats are Wi-Fi enabled, they may be controlled wirelessly, allowing the user to adjust the set points through your smart phone. So you can turn your heating on when you're on your way back from a weekend away, or off when you pop out unexpectedly.
Use the below table to better compare what options are available, and what you might want to utilize in your home. Please ensure they are compatible by utilizing the System Compatibility checkers below as well!

Smart Thermostats Return Policy:

Smart thermostats must be compatible with your existing heating system to install and use. Please check to see if your heating system is compatible before purchasing and opening.
