Ratings and reviews

Edit: a recent update improved this a lot! It would still be nice to have both thermostats on one screen, but now you can swipe between them easily. ----- Old review: Seems to connect to the thermostat a little more reliably than the old iComfort app. However it makes some of the same UI blunders (only one thermostat viewable at a time) and creates some new ones (switching thermostats takes several extra taps, changing mode takes even more).

Since the last update, the temperature on the thermostat and App don't match. They are off by several degrees. This makes the app useless because since you don't know the real temperature, you have to go to the thermostat to check. I have S40's. I paid a lot of money for my system and the least I expect is to have a functional app. According to customer service "They are working on the issue"

This app and the system it runs are wildly disappointing. It is very difficult to do even the simplest tasks. the thermostat and the app are inaccurate and we have a terrible time getting our home to a comfortable temperature. Reporting in this app is nonexistent. This was a giant step down from our Nest Thermostat and Google app. If we had known what an awful thermostat and app this is we would never have purchased it. So terribly disappointed. At least it doesn't crash my phone.
