It took a few tries at first to figure it out. Now that I have the hang of it I love it. I just ask alexa for the temp. in a room and I get it, or to change the settings on the thermostat she does it. I don't have to get up each time now.
Very difficult to connect to my wifi however once I got it connected it works great. It stays connected fine, just the initial connection was difficult.
Setting the unit up was a little tricky. When a problem was encountered the Android app had to restart from the beginning. Could have been me. Now that is complete, works great.
