Home Assistant Blueprint: Pause Playing Media During Calls

pause_media_during_calls.yaml

blueprint:
  name: Pause Playing Media During Calls
  description: >
    Automatically pause the playing media when you get a call!

    Currently this only works with the Home Assistant Companion app for Android.
  domain: automation
  input:
    phone_state_sensor:
      name: Phone state sensor
      description: >
        Select the sensor that holds the phone state you want to track.
      selector:
        entity:
          domain: sensor
    media_player:
      name: Media player
      description: Select media player to control. This will only work for entities, not areas or devices.
      selector:
        target:
          entity:
            domain: media_player

variables:
  players: !input media_player
  playing: >
    {{ dict((states.media_player|selectattr('entity_id', 'in', players.entity_id)|list )|groupby('state'))['playing']|map(attribute='entity_id') | list }}
trigger:
  platform: state
  entity_id: !input phone_state_sensor
  from: idle

condition:
  condition: template
  value_template: "{{ (playing | count) != 0 }}"

action:
  - service: media_player.media_pause
    data:
      entity_id: "{{ playing }}"
  - wait_for_trigger:
    - platform: template
      value_template: "{{ states[trigger.entity_id].state == 'idle' }}"
  - service: media_player.media_play
    data:
      entity_id: "{{ playing }}"

Here is some inspiration with my version, it uses mute and checks if the person is at home: https://gist.github.com/JackPoint/2375dd5d15f0b4c52161207170c14f60

Nice solution for the multi media player is playing check btw!
