Casting random Youtube video to device

Configuration
1

Hello,

I’m very new to HA (so apologies if this question isn’t in the right place) but eager to learn.

I’ve set up an automation that, at a time in the morning, will cast a YouTube video to my Google HUB for a bit of ambience. It works great:

action:
  - data:
      media_content_type: cast
      media_content_id: " { \"app_name\": \"youtube\", \"media_id\": \"GyK6w4RVePg\" }"
      enqueue: play
    service: media_player.play_media
    target:
      device_id: 323a99912ae05ec9a79471e420b87103

What I’d like to do though is have it play a random video from a set of possible ones. How would I go about doing that? Would it be a case of stipulating all the possible videos in the automation YAML somehow, or is there a way to pick randomly from a list / DB of some kind?

Thank you.

It you want an reason to learn Node-RED this would be a good example to practice on. You could store the video content params in a JSON structure and then pick one using a random number function. You’ll need some JavaScript in a Function node and then a Call service node to do the casting. I have no clue how this might be achieved using YAML.

I’ve managed to accomplish this with the following YAML:

service: media_player.play_media
data:
  media_content_type: cast
  media_content_id:  '
  { 
  "app_name": "youtube", 
  "media_id": "{{ ["4u0i7UgrUuk", "kD8oLJoCxPk", "TKKfQUkEa7M"] | random }}" 
  }'
target:
  device_id: 323a99912ae05ec9a79471e420b87103
