It has great features. I particularly like the geofencing. The only thing is that it does not always recognize when I am home and gets stuck on away from home. I haven't figured out if there is something I can do to control/ fix that. I can still control it both at home and on my phone, so it is not a problem.
This thermostat has been amazing! I highly recommend. I like the modes which are energy saving and I really enjoy the app features. I purchased two additional sensors and its useful to see the temperatures throughout the house. I have yet to have a problem with this thermostat and installation was easy, I am a single mom of two toddlers and through the chaos was able to install it within an hour and half.
I now get to stay in bed and start the heater in the a.m. wonderful. I like being able to start the temp control from my phone. The readout is large and this helps with aging vision. The light is so bright that it serves as a hallway nightlight.
Difficult to connect to the Internet. Without an Internet connection it’s basically an old-fashioned dumb thermostat. The programming function doesn’t work without it. I followed the steps three times and even change the settings on my router but to no avail. Finally the AC repair guy came to work on my unit and was able to guide me through the process on my phone. Now it works great but it was very frustrating for two years.
The remote sensor and the master thermostat has no means to recalibrate these devices were that may be needed for some applications. It's not good enough to start that they are factory calibrated.
