ecobee Smart Thermostat Premium

The ecobee Smart Thermostat Premium combines climate control with a built-in air quality monitor and smart speaker powered by Siri and Alexa. Its standout feature is the included SmartSensor that detects occupancy and temperature in different rooms, automatically adjusting to keep occupied spaces comfortable.

While ecobee provides a well-documented REST API for developers, the thermostat relies on cloud connectivity for most smart features including scheduling optimization and energy reports. Basic heating and cooling schedules continue to work during internet outages.

The Premium model adds a zinc and glass design, built-in air quality monitoring for VOCs and CO2, and a speaker with microphone for voice control. It works with HomeKit, Alexa, Google Home, SmartThings, and IFTTT.
