This thermostat came with my new house (new build). We moved in a month ago. Since I installed the Honeywell Home app, I have been receiving notifications from the app indicating both thermostats are offline. I set them up using 2.4GHz, the wifi is strong enough to reach both thermostats, I have reset the wifi in both already and the notifications continue at least once a day. So, since the notifications became annoying and they both reconnect after a while, I just uninstalled the app and pretended they are not wifi enabled. What was the point of these thermostats then? Not sure yet.
