YAML help needed for intent_script: 'media_player' is undefined when rendering '{{ media_player }}'

[shrewd gorge]

I'm trying to build a custom intent file to control my music. I've followed the guide at https://www.home-assistant.io/voice_control/custom_sentences_yaml/ but I keep getting errors. Been trying for several hours to find the issue but no success.

Hope a fresh set of eyes help:
configuration.yaml:
intent_script: SpotifyPlaylist: speech: text: Okay, ik speel de playlist af in de {{ media_player }}. action: - action: spotcast.start data: force_playback: false random_song: true repeat: "off" shuffle: true offset: 0 start_position: 0 ignore_fully_played: false entity_id: "{{ media_player }}" uri: "{{ playlist_id }}"

custom_sentences/nl/media.yaml:
# Example config/custom_sentences/en/media.yaml language: "nl" intents: SpotifyPlaylist: data: - sentences: - "(Speel|start) [de] (playlist|afspeellijst) {playlist_id} [maar] [af] (in|op) de {media_player}" lists: media_player: values: - in: "slaapkamer" out: "media_player.bedroom" - in: "kinderkamer" out: "media_player.lenn" [..] - in: "deurbel" out: "media_player.g4_doorbell_speaker" playlist_id: values: - in: "len[n][s] favoriet[en]" out: "spotify:playlist:5AP6JNb6Z2dSAkeeJP768d" - in: "lenn" out: "spotify:playlist:54MxfdxhOGO2WEKt2LCF7z" - in: "milenco" out: "spotify:playlist:29aiPfdrGUh6TDEjvsJV3r" - in: "kerst" out: "spotify:playlist:37i9dQZF1DX4dopZ9vOp1t" - in: "top 2000" out: "spotify:playlist:1DTzz7Nh2rJBnyFbjsH1Mh"

The error I'm getting:
Template variable warning: 'media_player' is undefined when rendering '{{ media_player }}'

Have you looked into Music Assistant at all?

There's a repository there for voice control of music 🙂

Could look at https://github.com/music-assistant/voice-support for inspiration, or use Music Assistant if that suits your purposes 🙂

But to answe directly the question about media_player not rendering, you would be better off utilizing slots and domains to automatically target applicable media devices

For example, here's a custom sentence I have to handle muting media players:

language: "en"
intents:
  MediaPlayerControl_ClearPlaylist:
    data:
      - sentences:
          - "Clear playlist on <name>"
        requires_context:
          domain: "media_player"
      - sentences:
          - "Clear playlist"
        requires_context:
          area:
            slot: true

so <name> will automatically populate a name slot with the name of the media player, since it is locked to the media_player domain. So it will trigger on any media player entity

Thanks Nick, I've been doing quite some Google searches today but havent found that one, found two other repos

For what you are trying to do, Music Assistant may simplify things a bit

Using domains, can I then using the Assist aliases I set on entities/devices?

[covert rose]

using the above sentence I made, here's the script that takes that name and maps it to the entity:

description: "Used to clear the playlist on a media player. Takes either the argument 'name' which is the media player to clear the playlist on, or area which is the area the request is made from."
action:
  - service: media_player.clear_playlist
    target:
      entity_id: >-
        {%- if area %}
        {{ states.media_player | selectattr('entity_id', 'in', area_entities(area)) | selectattr('entity_id', 'in', integration_entities('music_assistant')) | map(attribute='entity_id') | join(', ') }}
        {%- else %}
        {{ states.media_player | selectattr('name', 'match', name) | selectattr('entity_id', 'in', integration_entities('music_assistant')) | map(attribute='entity_id') | list | first | default }}
        {%- endif %}
speech:
  text: >-
    Playlist cleared 
    {% if name -%}
    on {{name}}
    {%- endif -%}
    .

Yes, it will consider friendly names and aliases

when using intent scripts/custom sentences

Hmm okay, thanks again

That might work instead of this. I was hoping for a simple thing I've missed since I've been trying for 7 hours 😄
