The only issue I have is with the iOS app; it does not always synchronize properly with the thermostat. Occasionally, I have to force quit the app to get it to update.
Easy to set up and I love the app that you can also use on your phone. You can use it anywhere with Wi-Fi. I have adjusted the temp while away and you can set up a vacation away mode to set the temperature for the days you are gone.
Thermostat works great, but connecting to wifi is finnicky. Took several tries to get it to connect and the process is very slow. Need to fine tune this software. Also, for some unknown reason, it lost the connection after a few weeks and had to be re-programmed. (p.s.. I am using a mesh wifi system and coverage is excellent throughout the house and yard near the house.
