It's horrible and extremely complicated to get the wifi setup and on my phone...to think your customers need to push the thermostat and then you have 5 steps on your phone and then need to get in and out of the app is just total chaos and nuts. I also have a Lennox and what a joy and simple vs. this piece of crap!
A great thermostat to use compared to the previous mechanical one I had. Responds perfectly well to temperature changes in the house keeping whatever temperature I program it to. I think it money saving on energy.
I’ve had this installed for a few weeks at this point and overall, I like it. It takes a while to get used to the mode and menu layout and options. The install was done by a contractor but I did the initialization and configuration and I had to run through that process 2 or 3 times before it worked. I still don’t know why. But I had exactly the same issue when I tried to configure the second T6. And it does frequently lose wi-fi connectivity, so it disappears from the app when that happens. But then it eventually finds itself again. Even when it is offline the touch screen controls still work.
