Read the full review first if you are still deciding: ecobee Smart Thermostat Premium Review .
Getting started
- Install the thermostat and set it up in the ecobee app. Pick the built-in voice assistant you want: Siri (needs a HomePod as a home hub) or Alexa Built-in (ecobee Smart Thermostat Premium ).
- Place the SmartSensor in a room you actually use. It reports temperature and whether the room is occupied (ecobee Smart Thermostat Premium ).
- Set a schedule, then turn on eco+ (ecobee Smart Thermostat Premium ).
- If you use HomeKit, add it to the Home app as well. ecobee lists Apple HomeKit, Alexa, Google Assistant and SmartThings (ecobee Smart Thermostat Premium ).
How the AI works
- Occupancy: the thermostat has radar occupancy and proximity sensing, and the SmartSensor detects occupancy in other rooms (ecobee Smart Thermostat Premium ).
- eco+: ecobee’s set of features that adjusts heating and cooling using occupancy, your schedule and local energy information (ecobee Smart Thermostat Premium ).
- Learning: ecobee says it learns how long your home takes to heat so it can pre-heat before your schedule changes (ecobee Smart Thermostat Premium ).
- Air quality: the Premium includes indoor air quality monitoring (ecobee Smart Thermostat Premium ).
- Subscriptions: ecobee says Smart Security features need a subscription (ecobee Smart Thermostat Premium ).
Home Assistant options
There are two routes. The official ecobee integration uses ecobee’s cloud. Since Home Assistant 2026.3 it signs in with your ecobee username and password, no developer API key needed, and older keys still work (Home Assistant ecobee ). For local control, add the thermostat through the HomeKit Device integration instead (Home Assistant HomeKit Device ).

Can Claude or ChatGPT control it through Home Assistant?
If the device is in Home Assistant, yes, indirectly. Home Assistant’s Model Context Protocol integration makes Home Assistant an MCP server that Claude, ChatGPT, Claude Code and other MCP clients can connect to over OAuth. With the Device control tool set, the agent only sees entities you have exposed to Assist. Cloud agents need your Home Assistant reachable from the internet. Source: Home Assistant MCP server docs .
