Our Verdict
Based on our scoring, the Ecobee SmartThermostat Premium comes out on top with an overall score of 9.5/10. Ecobee's killer feature is SmartSensors — small wireless sensors placed in bedrooms or living areas that feed temperature and occupancy data to the thermostat. Instead of conditioning air based on the hallway temperature, it averages across all sensors. The included sensor plus the option to add more makes it the best choice for multi-story homes or rooms that are chronically too hot or cold.
