Which ecobee smart thermostats should I buy?

ecobee's current thermostats are the Smart Thermostat Premium, Enhanced, Essential and Lite.

Only the Premium has built-in voice (Alexa or Siri), an air quality monitor and a SmartSensor in the box. None of the four is Matter-certified. Premium and Enhanced have radar occupancy sensing and include the Power Extender Kit. An Essential or Lite takes SmartSensors for occupancy, and the kit is sold separately. All four list HomeKit, Alexa and Google Assistant. ecobee sells the Lite only through professionals. It no longer sells the SmartThermostat with voice control, ecobee4, ecobee3 lite or ecobee3 new.

Lite Pro is not a separate model. It is the Smart Thermostat Lite, which ecobee sells to both homeowners and contractors with the same specs.

Older models. ecobee no longer sells the SmartThermostat with voice control, ecobee4, ecobee3 lite or ecobee3 new. All four still work with SmartSensors, and ecobee still sells the ecobee3 lite certified refurbished. Only the voice-control model and the ecobee4 have Alexa built in. The Power Extender Kit works with the Premium, Enhanced, ecobee3 lite, voice control, ecobee4 and ecobee3. It also works with the Essential and Lite, which do not include one.

Matter. No ecobee thermostat is in the Matter certified-product database. HomeKit, Alexa and Google reach these thermostats through each platform's own ecobee link.
