I have this Honeywell thermostat and love it. I installed it myself and have had it a few years with no issues.

I can't remember what brand mine is without looking at it. Not a Nest. Nice to be able to check it from my phone; my app is set to automatically set it to "Away" status if my phone goes more than a mile from my house. Which is fine since I live alone.

I installed the Ecobee 4 about six month ago and like it. Can voice command from couch.
