Why upgrade to a smart thermostat?

ADJUST THE TEMPERATURE FROM THE SOFA!

No need to get up (or even be home) – now you can adjust the temperature from your smartphone or by speaking to a smart assistant, including Alexa and Google Home.

OPTIMIZE YOUR ENERGY USAGE TO SAVE MONEY

Smart thermostats make it easy to set a heating and cooling schedule that adapts to the current weather, the changing seasons, and your own schedule to save you money.

AUTOMATE YOUR HOME’S COMFORT
