"The best reason to get any Ecobee is the Smart Sensors — they detect both temperature and occupancy, so the heat only runs in rooms where people actually are."

"It worked flawlessly. Display was responsive, menus easy to navigate. When temperatures dipped low it reliably turned on my heating."

Additional SmartSensors only come in 2-packs at $99+ — can't buy a single sensor if I only need one more room
Source: Amazon reviewerThe Ecobee SmartThermostat Premium is the most platform-agnostic smart thermostat available — it works simultaneously with Alexa, Google, Siri, and SmartThings without choosing sides, and the included SmartSensor's room-level occupancy detection can noticeably reduce heating and cooling bills. No mandatory subscription. The Eco+ override complaints are worth reading before you enable it, and the built-in speaker is no substitute for a real smart speaker.
