Exposing devices

To be able to control your devices over a voice command, you must expose your entities to Assist. This is to avoid that sensitive devices, such as locks and garage doors, can inadvertently be controlled by voice commands.

Exposing your devices to Assist

1. Go to Settings > Voice assistants.
2. Open the Expose tab.
3. Select Expose entities.
   1. Select all entities you want to be able to control by voice.
