I recently added the Devialet integration which officially only supports Phantom I and Phantom II. However, it can successfully add the Devialet Mania as well. The sad part is that it doesn’t seem to recognize the play/pause functionality.
@fwestenberg : If you would be willing to add support for the Mania as well, please let me know what kind of debug information you need me to supply to make it happen. I’m in the HASS discord (handle: rasssta) if you want to take it by chat instead of here. Also, we can take it in Swedish then
