Feature Request: Integrate with Home Assistant's Voice Assistant section

[ankushg]

Is your feature request related to a problem? Please describe.
It's often tricky to maintain allowlist/blocklist filters outside of home assistant, especially in homes where people have differing levels of knowledge about the full home automation stack.

Describe the solution you'd like
It would be great if Matterbridge showed up in Home Assistant's built-in voice assistant section and integrated with the integrated GUI to expose/hide entities

Thanks very interesting idea... will check it.

It looks like entities exposed as voice assistant entities are available through the websocket API:

In the below example the light and 3 climate controls are configured as exposed.

Message:

{"type":"homeassistant/expose_entity/list","id":41}

Response:

{
	"id": 41,
	"type": "result",
	"success": true,
	"result": {
		"exposed_entities": {
			"sun.sun": {
				"conversation": false
			},
			"zone.home": {
				"conversation": false
			},
			"climate.airconditioning_living": {
				"conversation": true
			},
			"climate.airconditioning_den": {
				"conversation": true
			},
			"climate.airconditioning_bedroom": {
				"conversation": true
			},
			"switch.smart_plug_multimedia": {
				"conversation": false
			},
			"switch.smart_plug_computer": {
				"conversation": false
			},
			"light.smart_bulb_desk": {
				"conversation": true
			}
		}
	}
}

This looks to be a very interesting way to easily expose devices to matterbridge-hass directly from Home Assistant.

Known assistants as of now are:
KNOWN_ASSISTANTS = ("cloud.alexa", "cloud.google_assistant", "conversation")

Hi,
sorry for the late reply.

What do we do with this api?

[robvanoostenrijk]

Technically it could be used to allow matterbridge-hass to pull a list of configured devices from home assistant.
It might conflict to use this list when its also used for voice assistant white-listing.

Perhaps as an optional data source for matterbridge-hass to take in devices which are supported and where conversation: true?

[Luligu]

How can we do white listing with voice assistant?

My knowledge of ha is limited sorry...

Not my primary controller.

[robvanoostenrijk]

No problem, the process is described here:
https://www.home-assistant.io/voice_control/voice_remote_expose_devices/

Ideally you can just select entities from the full entity list in Home Assistant and mark them as exposed.
The result is then visible in the API response above as { conversation: true } for each item that has been whitelisted.
