Discovery of groupable media-players

[dan-s-github]

While working on adding a SourceMediaPlayer Entity to the Triad-AMS Custom Integration I noticed the lack of support for discovering groupable players that a media-player supports. I thought it would be handy if there was an action available that could be called to retrieve a list of groupable speakers for the current entity instead of having to configure them manually inside a card.
Discovery also allows to curate the list which is important in case of a matrix player like the Triad-AMS.

I wonder if this is a useful feature for this and other media player cards?

This would be useful. If you want to do something like this now you basically have to ask users to provide what integration their speakers use, or just straight up (like most cards do) ask users to fill in the speakers manually. It should probably use the same naming as the action to join speakers though. So get_joinable_speakers or something.

that’s what should come out of the architecture discussion, just need to get some more devs adding their thoughts Sent from my iPhoneOn 19/02/2026, at 9:32 AM, Anton T.
