The app frequently disconnects. I paired it successfully but then it disconnected and when I tried to repair, it was not accepting. Then it would, and redisconnect. I deleted the app and reinstalled only to have it disconnected again. It’s too unpredictable. I’ll stick to manual control
Fairy good thermostat, however it loses wifi connection from time to time. Sometimes there's WiFi connection, but it won't recognize my phone. This is a bit unconvincing but it is sporadic.
Stopped working after having it a little over a year and when I contacted support, I was told it wasn't my thermostat but my HVAC system. Had someone come out and it was the thermostat. So I replaced it with something more reliable.
