It will not recognize my Wifi. I have tried to connect many many times. Went both ways. Through the app and manually. As a contractor and as a consumer. It won’t work. It may be because I have a 5g 1,000 mbps internet signal and no 2.4 which means this product is behind the times.
This thermostat works fine as a normal programmable stat but I've tried a dozen times to connect it to our wifi following the step by step instructions with the same result, "can't connect". Seems to be wasted money at this point.
We purchased this with our new furnace and as we spend so much time away and at our cottage, the peace of mind we get from the ability to monitor and control remotely is fantastic. We are very happy with the T6.
I have two units which were professionally installed, so I cannot comment on that. My wife and I connected the units to the Honeywell Home app, she on her Apple (iOS) phone and me on Android. The app can be a little esoteric, but once figured out it works well. We also can control it with Amazon Alexa. But be aware, Alexa only can control the thermostat when it is in either heat or cool, but not when it is on auto. One more tip, when you install the second thermostat, you must uninstall then reinstall the app on your phone before it will fully recognize the second unit.
The actual unit appears to work and is simple enough to use. However, the GeoFencing doesn't work well with two iphones X. When one leaves the Geofence area 1 mile, it pushes notification that noone is Home. Yet one is still at home and fortunately the unit keeps the Home setting for temperature. Exhibits issue with either iPhone leaving the area.
