Setup went relatively easy. The problem is with the app. After about two weeks the statistics page no longer works. It no longer shows temp or running time. Have tried uninstalling and reinstalling with no success. It is a shame because I like the thermostat, but because of the app it brings down the quality of the product.

The app is easy to use. It's really too bad it doesn't do anything though. It doesn't update the temp so when I'm away from home I'm unable to check. I'm also unable to make any changes from the app. The app shows these changes but the thermostat never does. It is connected and I've restarted everything. Again the app is easy to use it just doesn't work.

It finally connects and is working but I still don't like the set up. I liked the simple up and down buttons to set the temperature. And also I had it set to 75°. A bit later it was getting very warm. Checked the app and it set itself to 82°. I wish they just kept with the old app.
