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

No need to spin a dial whenever you get home, and your house can pre-heat while you’re commuting at the end of the day. Many smart thermostats tie into home automation systems such as HomeKit, SmartThings, and Wink.
