Thermostat works well at times. At others it seems to have a mind of its own. It jumps ahead to the next period on its own. We replaced one unit because it would not hold the settings. The APP makes this current unit more friendly because it is easy to adjust back to the setting that we wanted. I would really be unhappy if I had to go to the thermostat to figure out what to do.
I returned both thermostats due to the incompatibility of other smart products not working with my Samsung SmartThings. The thermostats worked very well, but the reason for choosing these items was to have one hub that worked for all of my products.
It didn’t work. Would not control HVAC upon installation. Must have been a defective unit. Removed and reinstalled unit a second time double checking all connections made. Same result. Replaced with new Nest E. Worked immediately.
There was a decrease in my monthly electric bill. I can set a schedule that prevents me from getting out bed to a cold house. In knows when no one is hone and sets the temperature to prevent keeping a empty house cold. I love it!
