Can i start a specific cast stream, on a specific device, using one button?
Pretty straight forward question.

I wanna start the TV, and then start a stream. Using one button.

Please
:v:t2::joy:

Don’t know if you still need it, but yes you can :slight_smile:
This code will send a given stream or audio/video file to say a defined chromecast.
yet i don’t have a clue on starting your tv first :wink: but this should get you started:

type: button
tap_action:
  action: call-service
  service: media_player.play_media
  service_data:
    media_content_type: audio/mp3
    entity_id: media_player.woonkamer
    media_content_id: https://stream.slam.nl/web16_mp3
    extra:
      metadata:
        metadataType: 3
        title: Housuh in de Pauzuh
        artist: Slam!

Just change the target device-id and off you go.
