Figuring out how to use it with WiFi took a little time as the directions did not seem very clear to me. Once I figured it out, I have been very pleased with the way it works
I had issues getting this thermostat to connect to my Wi-Fi when it was new. Reconnection should not require opening the app if the connection is lost. I have an older Honeywell Wi-Fi thermostat that puts this one to shame.
