Send spotify playlist to google audio

Configuration
1

Hi! I would be great to send a Spotify playlist throw HA, but can’t get it to work.

alias: Chromecast audio on - lungt & skönt i köket
trigger:
  platform: state
  entity_id: input_boolean.spotify_lungtochskont
  state: 'on'
action:
  - service: switch.turn_on
    entity_id: switch.google_audio_koket
  - service: media_player
    entity_id: media_player.spotify
    media_content_id: spotify:user:spotify:playlist:37i9dQZF1DXcwkNsfYPDPQ
    media_content_type: playlist
  - service: media_player
    entity_id: media_player.spotify
    source: media_player.kok

Any idea? Or solution to my request?

One problem could be that the spotify component can’t “see” the chromecasts unless you have started playing on them from an other source already, for example an android phone, at least that how it workes for my regular chromecast and google home.

A second point is the:

- service: media_player
    entity_id: media_player.spotify
    source: media_player.kok

I think it should be:

    - service: media_player.select_source
      data:
        entity_id: media_player.spotify
        source: Name_of_your_chromecast

Here is a script I have which i know works, but only when my Chromecast is already playing something from spotify, or recently has:

spotifydemo:
  alias: 'Spotify on Home'
  sequence:
    - service: media_player.select_source
      data:
        entity_id: media_player.spotify
        source: Living room Home
    - service: media_player.shuffle_set
      data: 
        entity_id: media_player.spotify
        shuffle: 'true'
    - service: media_player.play_media
      data:
        entity_id: media_player.spotify
        media_content_type: playlist
      data_template:
        media_content_id: 'spotify:user:trisk3lion:playlist:1KH7pw5kxsppOdINedp8Ub'

I figured out a work around over on Spotify Playlist Player
