I have gas baseboard heat and central air
This thermostat let me know that that my boiler wasnt working. It sent me email alerts telling me that the temperature in my house had dropped to where i needed to be concerned. I was 1800 miles away at the time.
I wouldnt trade this device for anything else. Well any other brand. I have friends that bought other (N--t) brands and swapped for this
Sfranci about Total Connect Comfort
