The thermostat is great but the app has very limited functionality! For example I can't switch between slab and air temperature sensing from the app. I may have to return the thermostat because the app does not perform up to expectations. Just make the app the same as the thermostat interface!

Really not that impressive. Think twice. Cant seem to get the app to control 2 different stats...one on east coast and other on west coast....that’s why I bought wifi! Sheesh

The thermostats are great but the app is pretty much useless. When you pay a ton of money for the thermostats it's not unreasonable to expect the app to have the same features as the thermostats. Other than adjusting the temps (you can't turn them on and off with your phone) if you're away. Why aren't there off/on buttons on the app. Go figure. If I'd known the app was this crappy I wouldn't have blown $1500.00 on thermostats.

The app could do so much more. Smart home integration could be so much more complete. Go in with low expectations and let’s hope the vendor improves things over time.
