Works great , and controls my new AC/Heater . I would buy other Honeywell products because the app works well . It’s easy to use and has all the features I need like scheduling and monitoring .
better smart thermostats are available (Ecobee) - this one does not even show outside temperature and user interface is not intuitive it won't give you feedback as to better programs/settings, it has no motion detector so has no idea if you are home or not. You can do better
