Good functionality but went off line when we were traveling. Had to reset the router when we returned home to get the thermostat communicating with the app. I think the purpose was to be able to communicate remotely. Hopefully it doesn't happen again.
This thermostat is so simple to program the Wi-Fi and password, The thermostat also has humidity on the screen along with accessing the clock set from the Internet. The phone app let you control everything to do with the thermostat right from your couch.
It is sleek and small. We are remodeling our kitchen and dining room and had to relocate the thermostat to another wall, right in front of the new cabinets being installed. This fits in perfectly. The app works great as we can adjust the settings while away! Great smart thermostat!
Really easy to use. Controls our HVAC just like we wanted it to work. Keeps our home temperature almost exactly where we set it at. Completely happy with this controller.
