The App stops working. It shows the thermostat is offline while the thermostat shows a good connection. The only solution that works for me is to repeat the configuration of the thermostat, a slow and unpleasant process.
Works well, installation generally ok but uses own wifi to connect to phone vs Bluetooth likenother smart home devices. Makes installation more clumbsy and error prone. Had one problem for whick I called support. They were very responsive
I have started using the Honeywell Home App. after my electric Bill jumped to twice my usual amount. With the App I can control and use electricity saving temperatures during SLEEP Mode and also make changes to the Wake Time, HOME Time, and also the temperatures during these Modes. I will know the effect of these Changes and Controls after I get my next Billing Statement.
