Does a better job than the other smart thermostats I've used and the app gives you all the information you need to make the best use of your home heating dollars.

Love the sleek modern look!

Love the sleek more modern look of these! The ability to control them remotely from your phone, set schedules and lock them is fantastic. You’d never know they were plastic they look and feel so nice.

Love the thermostat

Love the thermostat. Great design. East to use. Only slight issue is the touch screen. To activate the up and down temp selection the area to tap on the arrow is extremely small.

Easy to install and use

Relatively easy to install and like the ability to turn down the brightness of the display, including turning it off completely. App is easy to use.
