Random MP3 file

Configuration
1

Hello,

I want to play a random mp3 file from a repository.

until now i use :

media_content_id: /media/local/music/{{range(1,10)|random}}.mp3

if i add 5 mp3 i need to change it to

media_content_id: /media/local/music/{{range(1,15)|random}}.mp3

any idea how this can be dynamic ?

thanks

This sensor will generate a list of mp3 files that you can pick a random one from.

3

But still to know, how i can pick a random file from the folder without putting a range ?

4

Create the folder sensor then show me what the attributes are in Developer Tools / States.

Here is the result

You now have a list of the files in your directory. Pick one at random from that list and play it.

4f81986d33c976ac30717b89ce2bb040e8fc3d96

media_content_id: "{{ state_attr('sensor.media', 'file_list')|random }}"

Note that the file path is part of the file list elements so you donā€™t need to specify it.

EDIT: looking closely at your file list you may not have specified the correct path for the sensor. It probably needs to be /media/local/music/

Thanks for these contributions.
I am also trying to get this working but without success so far. Having trouble with the paths.

Before attempting this I had

homeassistant:
  media_dirs:
    media: /media

and the Media Browser would play .mp3 files from various folders including /media/Music/Playlist. The full path being
/usr/share/hassio/media/Music/Playlist

The developer tool shows this when playing from this folder -

media_content_id: http://192.168.1.29:8123/media/media/Music/Playlist/Ike%20n%20Tina%20Turner%20-%20Nutbush%20City%20Limits.mp3?authSig=....

I set up

homeassistant:
  allowlist_external_dirs:
    - "/media/Music/Playlist"

and

sensor:
  - platform: folder
    folder: "/media/Music/Playlist/"

as the only valid config.yaml allowed.

I get this for the sensor-

so its seeing the tracks I want.

But when I launch my script using
media_content_id: ā€œ{{ state_attr(ā€˜sensor.playlistā€™, ā€˜file_listā€™)|random }}ā€
the developer tool shows

media_content_id: http://192.168.1.29:8123/media/Music/Playlist/Ike%20n%20Tina%20Turner%20-%20Nutbush%20City%20Limits.mp3?authSig=....

i.e with one ā€œmediaā€ folder level short, and the player does not play the track.

If I change media_dirs to this -
media_dirs:
media: /

the developer still shows

media_content_id: http://192.168.1.29:8123/media/Music/Playlist/Ike%20n%20Tina%20Turner%20-%20Nutbush%20City%20Limits.mp3?authSig=....

and the track does not play.

Where to go with this?
TIA

This is my script-

play_random_track:
  alias: Play a Random Music Track
  sequence:
  - service: media_player.play_media
    target:
      entity_id: media_player.living_room_speaker_2
    data:
      media_content_id: "{{ state_attr('sensor.playlist', 'file_list')|random }}"
      media_content_type: music

  mode: single
9

Try this:

media_content_id: "/media{{ state_attr('sensor.playlist', 'file_list')|random }}"
10

Of course. (Slaps forehead).
Thanks.

So how much trickery is required to loop continuously and randomly through the folder until manually stopped. I am not big on scripts as you may have guessed.
I guess it would be check the player state for idle and restart the sequence. Something like

play_again:
  alias: Play Again
  icon: hass:play
  sequence:
        repeat:
          while:
            - condition: state
              entity_id: media_player.living_room_speaker_2
              state: "idle"
            # Don't do it too many times
            - condition: template
              value_template: "{{ repeat.index <= 20 }}"
          sequence:
            - service: script.play_random_track
  mode: single
11

Thatā€™s one way.

Another way would be to automate it:

trigger:
  - platform: state
    entity_id: media_player.living_room_speaker_2
    to: idle
  - platform: state
    entity_id: input_boolean.continuous_play
action:
  - choose:
      - conditions:
          - condition: state
            entity_id: input_boolean.continuous_play
            state: 'on'
        sequence:
          - service: script.play_random_track
    default:
      - service: media_player.media_stop
        entity_id: media_player.living_room_speaker_2

You would have to create the input boolean obviously. When it is toggled on random tracks play continuously, when toggled off the music stops immediately.

The automation works a treat. Thanks.
I didnā€™t get the play_again script to run properly. It stops after playing the one track.
Is there a function to replace random that could play sequentially by name alphabetically?

13

There is a next track service you could use: https://www.home-assistant.io/integrations/media_player/#services

Not sure what happens when either no track or the last track is playing.

Hello Tom,

Sorry for delay, iā€™m almost done, but still have an issue :

here is my config :

  allowlist_external_dirs:
    - /media/aya_nahil/histoires
    - /media/Athan
    - /media/Encore une histoire
    - /media/English Story
    - /media/La puce Ć  l oreille
    - /media/La famille

Here is developer Tools sensor result :

Screenshot 2021-07-31 202216

Here is my automation :

media_content_id: '{{ state_attr(''sensor.la_famille'', ''file_list'')|random }}'

But i had an issue with the URL.

2021-07-31 20:23:18 ERROR (Thread-10) [homeassistant.components.cast.media_player] Failed to cast media https://chuck-norris.duckdns.org:8123/media/La%20famille/48.mp3?authSig=ey... from external_url (https://chuck-norris.duckdns.org:8123). Please make sure the URL is: Reachable from the cast device and either a publicly resolvable hostname or an IP address

i could play all mp3 of those folders with the old way i used :

media_content_id: /media/local/La famille/{{range(1,10)|random}}.mp3

in external dirs : it should be /media/local/La famille or /media/La famille ?

because /media/local/La famille is not working

Any idea?

Thanks alot

Try this:

media_content_id: "/media{{ state_attr('sensor.la_famille', 'file_list')|random }}"
16

Here is the result, as you can see there is /media/media.
I think it should be /media/local/ā€¦
but when i add /media/local/ la famille to the configuration file, the schema didnā€™t pass

Finally got an automation that plays a folderā€™s content in order from the first file to the last.

action:
  - repeat:
      while:
        - condition: template
          value_template: >-
            {{ repeat.index <=
            states.sensor.dire_straits_brothers_in_arms.attributes.number_of_files
            }}
      sequence:
        - service: media_player.turn_on
          target:
            device_id: 9d7c215c6bbeb89d4e6496bxxxxxxxxxx
        - service: media_player.play_media
          target:
            device_id: 9d7c215c6bbeb89d4e6496bxxxxxxxxxx
          data:
            media_content_type: audio/mp3
            media_content_id: >-
              media-source://media_source{{
              states.sensor.dire_straits_brothers_in_arms.attributes.file_list[repeat.index
              - 1]  }}
        - delay:
            hours: 0
            minutes: 0
            seconds: 11
            milliseconds: 0
        - wait_template: '{{ is_state(''media_player.living_room_speaker_2'', ''idle'') }}'
mode: single

Works for sub folders in the path also.
Good option to random playing.

Wow this is complicated! Does it work on SMB shares also? Iā€™m unable to add my NAS share to the allowlist or the Folder sensor.

Have almost the same problem. Did you solve this?

20

Have this setup:

homeassistant:
  media_dirs:
      media: /config/media
    allowlist_external_dirs:
      - /config/media/karacsony
      - /config
    allowlist_external_urls:
      - https://MYDNDNS/config/media/karacsony
    whitelist_external_dirs:
      - /config/media/karacsony

sensor
  - platform: folder
    folder: /config/media/karacsony

Get this:

path: /config/media/karacsony/
filter: '*'
number_of_files: 4
bytes: 27949440
file_list:
  - /config/media/karacsony/03.mp3
  - /config/media/karacsony/02.mp3
  - /config/media/karacsony/01.mp3
  - /config/media/karacsony/@eaDir
unit_of_measurement: MB
friendly_name: karacsony
icon: mdi:folder

On call service working good (you see no config folder)

service: media_player.play_media
data:
  media_content_id: media-source://media_source/media/karacsony/01.mp3
  media_content_type: audio/mp3
target:
  entity_id: media_player.google_home_mini

But if I want to play random mp3 from that folder:

alias: Karacsony
sequence:
  - service: media_player.play_media
    target:
      entity_id: media_player.google_home_mini
    data:
      media_content_id: >-
        media-source://media_source/{{ state_attr('sensor.karacsony',
        'file_list')|random }}
      media_content_type: audio/mp3
mode: single

Get this errors:

Failed to cast media media-source://media_source//config/media/karacsony/01.mp3. Please make sure the URL is: Reachable from the cast device and either a publicly resolvable hostname or an IP address
Failed to cast media media-source://media_source//config/media/karacsony/02.mp3. Please make sure the URL is: Reachable from the cast device and either a publicly resolvable hostname or an IP address

What I see this script:

media_content_id: >-
        media-source://media_source/{{ state_attr('sensor.karacsony',
        'file_list')|random }}

always insert a config path before /media/karacsony/ and thats why cant play the music on my google home. When i call form developer tools not write this config folder only media/karacsony and working good.

But in the configuration files must use config folder because I use Home Assistant in docker and only accept it with config and then the other folders.

How can I solve this problem?
