Best Overall
ecobee Smart Thermostat Premium
Our verdict: Wi-Fi, a Smart Sensor and built-in Siri and Alexa, in one of the most complete packages here.
The Premium is ecobee's flagship, combining Wi-Fi, a Smart Sensor and built-in Siri and Alexa voice control. It is the only model here that lets you talk to the thermostat itself, with no separate speaker needed.
It takes first place because the sensor changes how the system behaves. A thermostat measures temperature only where it hangs, which is usually a hallway, so a remote sensor lets the system read the room you actually live in. That is a real comfort gain in a house with a hot upstairs or a cold bedroom. It sits above the Nest on feature depth, and above the Essential on the sensor and voice built-in.
Buy it if you want the most capable all-round unit. The tradeoff is price: it sits in the $200 to $500 bracket, the most expensive tier in this list.
