Constantly have to reconnect my thermostat to the app. Every few weeks my Lyric Thermostat disappears from the app and I have to reconnect it. This happens for no apparent reason. In the 2.5 years I've been using it I've probably had to reconnect it over 10 times. I never had this problem with the Nest I used to have at my old home. Even more frequently than that, it loses connection with Google. On top of that, I frequently have to try multiple times to set it up again. Update: I am tech support.
