Wonderful integration with app. The only thing I would wish for would be automatic switch between heat and cool functions so that it keeps a more even temperature.
I love these thermostats. I installed two in a rental house (one per apartment) and can monitor the heat and adjust if needed remotely no matter where I am. Pretty cool! Also, good interface for both me and my tenants.
The app is really poorly architected, I have 2 units and I have tried to configure both except one worked and the 2nd one just times out... Not sure why you have to go back and forth multiple times to verify instead of app' finding the thermostats.
