"The Raumfeld system is a closed system that can only be operated via its own app (except Spotify Connect).
Control via other software is not intended.
The integration of a media server always comes with small restrictions, as Raumfeld then has no direct access to the titles and tags.
This means that one tag or another may not be transferred from the media server and cover images may not be transferred either. It helps to integrate the music collection via a network drive (smb) or USB, as Raumfeld then has direct access to folders and files, as well as their tags.
Since we are aware of the fact that many users would like to use an open system to be able to use their favorite apps, we are currently developing the Teufel Home System.
The Motiv Home is the first speaker of this new generation. More will follow soon. Any app can be used to control this via Chromecast or Airplay2."
This would mean that I probably have to invest in new speakers,what I definitely won't do.
At this stage I have to understand that I now have some really overpriced Bluetooth speakers.
Maybe the answer is similar to what you received from Sonos.
