For a first smart thermostat, the best smart thermostat should be easy to set up and use daily. App control, clear schedules and a readable display matter more than extra features at first. Learning control, occupancy sensing and touchscreens all appear in the six models.
We reviewed manufacturer specifications and owner feedback to pick these thermostats. First-time buyers can start with our best smart thermostat 2026 and smart thermostat reviews guides. Our Editorial Policy lays out how we chose these first 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.
