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.
I received this Thermostat with my new HVAC system. Two major problems. The first, although it only affects some counties/states, it ASSuMEs that your location observes Daylight Savings (really dumb). The second is that it "LEARNS". Well, I don't want something that "LEARNS". Again Honeywell ASSUMES that I want my system to start up before the time that I set. I DON'T. Honeywell has no idea where the system is located in relation to master bedroom or other bedrooms. Some people have very sensitive hearing. I don't but I hear when the system comes on and it does it as much as 45 minutes before my set time. Stay away from this product.
