Control volume with "variable" custom-component

Installation Home Assistant OS

Hi. Very happy to have discovered the variable custom component by @rogro82

But I am having a small problem on it’s use. I basically have a Google Home that is also my doorbell speaker. It’s volume is usually under 50%, but when the doorbell rings I want to bump it up to 80%, then back to whatever it was previously set to. I’m sure variable can help me do this.

This is my basic declaration:

variable:
  mario_volume:
    value: '0.3'

So, do I capture the current volume with something like this? Or does value_template need to be done from an automation?

variable:
  mario_volume:
    value_template: "{{ is_state_attr('media_player.mario','volume_level','0.3') }}"

And presuming I can this working and I have rung the doorbell at 80%. Do I restore the media player’s volume with something like this in an automation or script?

  alias: Mario Volume Reset
  sequence:
  - delay: '00:00:15'
  - data:
      volume_level:
        value_template: "{{ is_state_attr('variable.mario_volume','value','0.3') }}"
    service: media_player.volume_set

Thanks!

This great custom-component was able to do this. I worked it out and thought I’d post my method in case somebody needs a similar solution one day. My first post’s code is messy - please ignore.

configuration.yaml

variable:
  mario_volume:
    value: '0.4'

script.yaml

mario_vol_read:
  alias: Mario Volume Read
  sequence:
  - data:
      entity_id: media_player.mario
    service: media_player.turn_on
  - delay:
      seconds: 0.5  # ensure the Google Home device is 'awake', after being turned on
  - data:
      value_template: >
        {% if is_state('media_player.mario', 'idle')  %}
          {{ states.media_player.mario.attributes.volume_level }}
        {% elif is_state('media_player.mario', 'playing')  %}
          {{ states.media_player.mario.attributes.volume_level }}
        {% else %}
          0.4
        {% endif %}
      variable: mario_volume
    service: variable.set_variable
mario_vol_write:
  alias: Mario Volume Write
  sequence:
  - delay: 00:00:15  # ensures that my mp3 has had time to fully play before lowering the volume
  - service: media_player.volume_set
    data_template:
      entity_id: media_player.mario
      volume_level: '{{ states.variable.mario_volume.state }}'
doorbell:
  alias: Doorbell
  sequence:
  - data:
      entity_id: media_player.mario
      volume_level: '0.8'
    service: media_player.volume_set
  - data:
      entity_id: media_player.mario
      media_content_id: https://domain.duckdns.org/local/audio/big_ben_doorbell.mp3
      media_content_type: audio/mp3
    service: media_player.play_media

automation.yaml

- id: '1552947283000'
  alias: Doorbell
  trigger:
  - entity_id: binary_sensor.doorbell
    from: 'off'
    platform: state
    to: 'on'
  action:
  - service: script.turn_on
    entity_id: script.mario_vol_read
  - service: script.turn_on
    entity_id: script.doorbell
  - service: script.turn_on
    entity_id: script.mario_vol_write

Hope that helps!!

With sincere thanks to @rogro82
