You want useful features for the money, and the best value smart thermostat should deliver them without premium extras. App control, schedules, room sensors and geofencing cover most daily needs. Value here means strong daily features, not the longest list of extras.
We looked at manufacturer specifications alongside owner feedback to choose these thermostats. Value shoppers can start with our best budget smart thermostat and best smart thermostat guides. Our Editorial Policy explains how we judged value in these thermostats. Turn off power at the breaker before removing an old thermostat. Thick 120V or 240V wires mean line-voltage heat, so call a licensed electrician.
