Had these powered up in our storage facility, we lost power for about 30 seconds and now I have to go back and set all of these back up so they work with the app. What a pain in the behind.
Took 3 different HVAC techs before I found one that could connect my cell up to the thermostat. I had given up on connecting remotely, but a tech that came out for a repair was able to do it. Also, you can't program any of the days as a group but must program each day. Very inefficient as compared to the previous thermostat I had when I replaced the furnace in previous house. I could do M-F & weekends as a group.
