Yes it does help actually. Still not 100% what I am after but now I have:
intents:
PlayerPauseArea:
data:
- sentences:
- "hold the music"
requires_context:
area:
slot: true
intent_script:
PlayerPauseArea:
action:
service: "media_player.media_pause"
data:
entity_id: "{{ expand(states.media_player) | selectattr('entity_id', 'in', area_entities(area)) | select('search', 'ma_') |map(attribute='entity_id') | join }}"
speech:
text: "Paused"
I love progress! Now to play with it some more so I can either call for a specific player or the area will be recognised but have it all in one intent. BTW the search is used to find the music assistant player as I have prefixed all their entity ids with ma_
