[KEF] [Google Home] How to get my LSX to switch sources?

This is my Home Assistant configuration:

google_assistant:
  project_id: <redacted>
  api_key: <redacted>
  exposed_domains:
    - media_player

media_player:
  - platform: kef
    host: 192.168.3.26
    type: LSX
    name: Speakers
    maximum_volume: 0.6

I can currently turn my speakers on/off (“Hey Google, turn my speakers on/off”) and control the volume (“Hey Google, set the speakers’ volume to 60%”) successfully. What do I say to get my LSX to switch b/w sources? I tried all variants I could think of - “switch my speakers’ source to Wi-Fi”, “change my speakers’ input to Bluetooth”, etc. - but it doesn’t work.

Fwiw Home Assistant already supports changing the speaker source using the widget in the Overview tab. I just need to find a way to make Google Home do it. It would also be convenient if I could use aliases for these sources when talking to Google Home (e.g., “TV” instead of “Opt”, “AirPlay” instead of “Wi-Fi”, etc.).

Hi @indigochild

I’m a noob in Home Assistant. I’ve just installed it.
How did you achieve the control of your LSX with Google Assistant?
Do you know if it’s possible to do the same with Siri, since I’ve some iDevices at home?

Thanks in advance for your reply!

EDIT: for the SIri part, just integrate the LSX speakers via the Homekit integration into Homekit.
So you can turn on/off the LSX speakers, mute them or play/pause music.
