Very Easy to Get Up and Running
This device was very easy to install and get working, which is good for someone like me, who is not exactly technically proficient. The sensor was also a walk in the park. We are still trying to figure out how to use it best, but it certainly does appear to do the job very well. It will be interesting to see if it helps with the electric bills.

Works as expected. upgraded to wifi.
Great upgrade to wifi thermostat. We added a 3 wire thermostat wire ourselves and mounted this to the wall with included hardware. Powered on, linked with our home router, downloaded the app and added a second room in minutes.

Solved a problem from a bad HVAC install
My home has a poorly placed thermostat directly below a HVAC vent (previous owner install). Rather than moving the old thermostat, this product made it super simple. I replaced the old thermostat with this one and installed the extra sensor in a hallway in the middle of the house, away from vents. I was then able to set the priority of the temperature reading to come from the extra sensor, not the primary thermostat (still located under a HVAC vent). My AC and Heating units now work a lot better!

Initial impression fair but will let you down shortly after
My home did not have programmable thermostat so I purchased this one and two additional sensors. First the box did not come with the setup instructions like it was a open item but I did not purchase that.
After a longer than normal setup I had the sensors connected and went to get it working with my phone. Another hour wasted because the app need to be restarted after it days the app could not find/connect with the thermostat. All was well for there weeks until the app and thermostat got out of sync. The thermostat is correct but the app is showing a different temperatures and humidity by 5 degrees or more. I went with brand since they had some good reviews and I watched some diyers talk about the features and price point. Will return and buy a Nest and suggest that you save yourself the frustration and do the same.

Has been working good
Took me a while to install, although I had 24.5 VAC at the thermostat when I plugged it in I got nothing. After two evenings of trying to get this working I decided to buy a 24 volt transformer tucked my c-wire back into the wall and connected the transformer wires to the C and Rh terminal and added a jumper between the R and Rh. Now it works perfectly although the geofence did not work once. Hope this helps someone with a similar problem getting it installed.
