Once it is set up it works very well and I use it daily to monitor our house and its two thermostats. It took me several loops around the process to get things connected, but that could easily been just been my unfamiliarity with the process. Overall though, very happy with this!
I love my new Pro Smart Thermostat. It is easy to use and works efficiently. I have two thermostats in my home on different floors, and they work very well.
