How to count media players playing?

[Heijt771]

Hi all,

I currently use the below code to count the amount of lights that are on in my place:

  - platform: template
    sensors:
      lights_on:
          value_template: >
           {% set lights = [
             states.light.tv_light,
             states.light.table_light,
             states.light.kitchen_light,
             states.light.bedroom_light,
             states.light.wardrobe_light,
             ] %}
           {{ lights | selectattr('state','eq','on') | list | count }}

However when I tried adapting it to count media players playing, it does not work. As I do not fully understand how to work with templating I was hoping someone could tell me how to count the currently active media players.

This is my non-working code:

  - platform: template
    sensors:
      media_players_active:
          value_template: " {{ states.media_player | selectattr('state','eq','on') | selectattr('state','eq','playing') | list | count }}"
           {% set states.media_player = [
             states.media_player.bed_room_display,
             states.media_player.bedroom_tv,
             states.media_player.kitchen_speaker,
             states.media_player.living_room_speaker,
             states.media_player.living_room_tv,
             states.media_player.shield_tv,
             ] %}
             

Looking forward to your replies.

Cheers

Try this:

  - platform: template
    sensors:
      media_players_active:
          value_template: >
            {% set media_players = [
              states.media_player.bed_room_display,
              states.media_player.bedroom_tv,
              states.media_player.kitchen_speaker,
              states.media_player.living_room_speaker,
              states.media_player.living_room_tv,
              states.media_player.shield_tv,
              ] %}
            {{ media_players | selectattr('state','eq','playing') | list | count }}

Thanks a lot Tom!!

That did the trick.

Out of curiosity:
{{ media_players | selectattr(‘state’,‘eq’,‘playing’) | list | count }}

The media_players part, how is this syntax defined? I now know that you have media_players and lights, does that then mean that you also have scripts, automations etc…? Whereis this value defined?

Thanks again for the help

The first bit is just a variable used to store the list of media players. It can be named anything, e.g.

  - platform: template
    sensors:
      media_players_active:
          value_template: >
            {% set brown_trousers = [
              states.media_player.bed_room_display,
              states.media_player.bedroom_tv,
              states.media_player.kitchen_speaker,
              states.media_player.living_room_speaker,
              states.media_player.living_room_tv,
              states.media_player.shield_tv,
              ] %}
            {{ brown_trousers | selectattr('state','eq','playing') | list | count }}

It makes more sense to call the variable after what it is storing though.

I followed exactly what you said but it’s not working damn.

Anyone has a solution for this? Doesn’t seem to work, I’m guessing the formatting has changed over the years.

This still works on latest version:

{{ states.media_player | selectattr('state','eq','playing') | list | count }}

It does grab all media_players though so adjust the first part if you only want to include specific entities.
