Volumio doesn't stay visible as player

Hi there,

I am using Volumio as player for Spotify, iTunes (via AirPlay) and local music.

I was surprisingly successful on integrate Volumio & Spotify to my home assistant installation.

What I’ve done:
1.

-   platform: spotify
    client_id: xxx
    client_secret: xxx
    aliases:
      c6e56cf6b68c07041768b06e2f29a439e7724b0e: 'Volumio'
-   platform: volumio
    host: 192.168.0.88
input_select:
  spotify_source:
    name: 'Volumio'
    options:
      - Volumio

In Node-Red i added a call-service node with service play_playlist and this data (it’s my Discovery Weekly):

{
    "media_content_id": "spotify:playlist:37i9dQZEVXcMxQ6GlVULvC",
    "random_song": "true"
}

This works like a charme when I connect Volumio one time manually via the app.

My problem is that Volumio doesn’t stay visible for home assistant (or better the whole API).

I am using this Spotify plugin on Volumio because I don’t know any other:

I tried to switch from Multiuser to Single User in the plugin but that doesn’t help.

Do you have an idea?

Thank you very much!
