What Real Users Say
R u/hvac_nerd on r/homeassistant"The ecobee Premium is the best thermostat for Home Assistant users. HomeKit integration is rock solid, and the room sensors let you build smart comfort automations."
R u/energy_saver on r/smarthome"Saved 23% on heating in the first winter compared to my old programmable thermostat. The room sensors make a huge difference in a two-story house."
A GreenHomeBuyer on Amazon"Beautiful design and the air quality sensor is a nice bonus. Wish the touchscreen was more responsive though."
The ecobee Smart Thermostat Premium scores 84/100 in community sentiment, making it the top-rated smart thermostat in our database. The combination of room sensors, excellent build quality, and strong Home Assistant compatibility puts it ahead of the competition.
Room Sensors Change the Game
The included SmartSensor is the ecobee’s secret weapon. Place it in the room you’re actually in, and the thermostat adjusts based on that room’s temperature rather than just the hallway where the thermostat lives. Community members with multi-story homes consistently cite this as the feature that justifies the price.
Additional sensors can be purchased to cover more rooms, creating a comfort system that rivals commercial HVAC zoning.
Smart Home Integration
Home Assistant: The ecobee integrates via HomeKit Controller, providing local control without cloud dependency. Climate entities, occupancy sensors, and temperature data all flow into HA natively.
Apple HomeKit: Full support including Siri voice control and Home app automation.
Alexa: Built-in speaker and microphone turn the thermostat into an Echo device. Useful if you’re in the Amazon ecosystem, ignorable otherwise.
Build Quality
The Premium lives up to its name in materials. The zinc alloy body and glass touchscreen look premium on the wall — a significant upgrade from the plastic construction of budget thermostats. The display shows weather, time, and air quality readings when idle.
Energy Savings
Community reports consistently show 15-25% reduction in heating/cooling costs after switching from programmable thermostats. The combination of occupancy detection, room sensors, and smart scheduling drives the savings.
Where to Buy
Bottom Line
The ecobee Premium at 84/100 is worth the investment for homeowners serious about comfort and energy savings. Room sensors, local Home Assistant integration, and proven energy reduction make it the community’s top thermostat recommendation.
