Thermostat works just fine, however, both of the ones I have in my home consistently lose connection with the wi-fi even though there is nothing wrong with the wi-fi signal. I have given up on trying to reconnect them to the wifi because by the next day, it has lost connection. I really liked being able to control temp from my phone but the built in wi-fi technology needs some serious upgrades.
I have 3 zone system in my house and have 3 of these thermostats. They work well. I had a hard time getting the wireless base hooked up to the app, which I had to do for each thermostat. It took numerous attempts to get the thermostat to synch to the app for whatever reason. Other than the difficulty hooking up the base to the app, the only other thing I don't like is that it is not compatible with my alarm system. I want to use one app to control all the devices in my house. The thermostats work well once they are all hooked up and I like controlling it on the Honeywell app on my phone.
