Lovelace: Mini Media Player

Is anybody here who done it with the platform musiccast_yamaha? What is the path to the radio station?
i can’t get it to work… e. g. Radio>Favoriten>1LIVE doesnt work… i have a german receiver.

Here is my code:

delete

EDIT:
Here is my Solution for my Problem. It isnt compatible with musiccast_yamaha. It only works with the platform yamaha. To see the entity, the receiver has to enter in the config.yaml with platform yamaha and the ip.

Here is my Code for the Script:

alias: inselradio_receiver
sequence:
  - service: media_player.turn_on
    data: {}
    entity_id: media_player.yamaha_receiver
  - service: media_player.volume_set
    data:
      volume_level: '0.50'
      entity_id: media_player.yamaha_receiver
  - service: media_player.select_source
    data:
      entity_id: media_player.yamaha_receiver
      source: NET RADIO
  - service: media_player.play_media
    data:
      entity_id: media_player.yamaha_receiver
      media_content_id: Radio>Favoriten>Das Inselradio Mallorca
      media_content_type: NET RADIO
mode: restart
