I had to switch form my beloved Nest to this thermostat when swapped out my furnace/AC. It lacks nice features like voice activation and connection with google mini. the Phone app is also not very friendly and annoyingly doesn't seem to have an option for giving temps in Celsius. Definitely a step down...
Two problems with the product. The product uses an external sensor to measure the outdoor temperature but does not display the outdoor temperature which would be nice to have in a future software release. Also the product has lost the WIFI signal twice already in six weeks and needed to be reset.
As far as the thermostat itself goes, it works great. It's only the problems with the app that prevent me from giving it all five stars! I've submitted help requests to no avail.
Am so thrilled to be able to control my home temperature from anyplace in the world. My unit has big bold numbers that we can easily see and the unit is so easy and simple to understand.
