Went with this thermostat because - my existing conventional thermostat was a Honeywell (battery powered) - compatibility with Ring app (I have Ring doorbells - no security system) Good choice ... clear, concise instructions made installation easy (even with additional C wire - no more batteries), and operation through Ring app is likewise. Good set of features too - home/away temperature settings with geofence perimeter is especially nice. I expect this will pay for itself within a few months of electric bill savings.
