How to choose
1
Check for a C-wire
Most smart thermostats need a common (C) wire for power. If you don't have one, use an adapter or a model that works without it.
2
Sensors fix cold rooms
If some rooms are always colder, a thermostat with room sensors helps more than a fancy screen.
3
Look for utility rebates
Many energy companies offer rebates on smart thermostats. Check before you buy.

FAQ
Can I install a smart thermostat myself?
Usually, if your system is standard low-voltage. Turn off power first and follow the app's wiring guide. Call a professional for high-voltage systems.
Nest or ecobee?
ecobee is best for homes with uneven room temperatures thanks to sensors. Nest is best for simple, set-and-forget use.
