You can control Home Assistant devices using natural language by routing requests through the Assist API, which handles intent parsing and entity resolution automatically. This removes the need for manual entity lookups and verbose service calls for any HA-integrated device.

Yes, natural language home automation requires the Home Assistant Conversation API endpoint at /api/conversation/process. The Assist API forwards your text commands to this endpoint to parse intents, resolve areas, and execute actions across your integrated devices.

Home Assistant voice control requires setting the HASS_SERVER environment variable to your server URL and a valid HASS_TOKEN for authentication. Additionally, the curl binary must be available on the system to execute the API requests.

Yes, you can query and control multiple smart home devices across rooms with a single natural language command. The Assist API handles area context and entity resolution automatically, supporting lights, thermostats, vacuums, media players, and other HA-integrated devices.

Natural language commands via the Assist API work with any Home Assistant-integrated device, including lights, switches, thermostats, covers, vacuums, and media players. Both control and query tasks are supported across all rooms and areas configured in your Home Assistant setup.

Execution failures for Home Assistant natural language commands usually stem from missing environment variables, an invalid HASS_TOKEN, or lack of the curl binary. Verify that HASS_SERVER is correctly set and your token has the necessary permissions to call the Conversation API.
