Companion app as media_player entity

[bverkron]

Is your feature request related to a problem? Please describe.

No

Describe the solution you'd like

I would like to be able to "cast" media to the Home Assistant companion app on Android so I can play cloud TTS messages (from Nabu Casa or Google TTS) instead of just the "built-in" TTS that sounds very robotic. This could also serve as a media player for other audio as well.

Describe alternatives you've considered, if any

browser_mod which I can't seem to get working, is clunky, and has limitations and awkward workarounds.

Additional context

Before the companion app can look into this request the mobile_app integration needs to first support the media_player domain. Please create a feature request for HA core so they can fulfill that before we can proceed here.

I agree this would be useful.

I confirm, it would be a cool feature. @bverkron, tell me, did you create a task in the core project?

Agreed this would be sweet, made a feature request on the Home Assistant Forum, https://community.home-assistant.io/t/companion-app-as-media-player/611326
