The only change you'll need to make in BubbleUPnP (the app) is to play to the proxied Sonos renderer (same name suffixed with '(OpenHome)'), rather than the Sonos renderer itself.

Earlier, I said I should make enquiries about BubbleUpnP settings in the ‘Bubble forum’ – but I’m looking for other info too, particularly about multiple Bubble controllers accessing the same NAS music library – which doesn’t seem to be common in the Bubble community.
I have tried looking at the bubbleupnpserver2 page, the XDA thread and the Google groups,
But despite wading through posts back to 2020, I’m not seeing what I seek – though I can see lots of posts from simbun ;-)

So I’m being cheeky and asking here before launching into one of the three ways above.
If there is an explicit guide to the points below that I’ve missed, please advise.

I have Bubble uPnP on 3 android phones (family control) and 2-4 NexusII tablets (old versions, fixed point control) – with full licence but only 3 Google accounts - but no BubbleuPnP server on the NAS.
To prevent potential chaos when resetting Sonos group ‘lead units’, this thread has highlighted the need to ensure all the android apps all have the same Renderer settings for all the Sonos devices – so that could be a chunk of work to start with.

If I put BubbleuPnP Server on the QNAP NAS, can it be set to act as a ‘Master’ Bubble, with all the tablet/phone Bubbles being ‘slaves’ ? ie the mobile devices tell the NAS Bubble server what is wanted, but the NAS version does all the actual work, communicating what it has done back to all the slaves ?
If so, would it mean I’d only need to set up Renderer settings on the NAS version and inconsistencies in the mobile renderer settings would become irrelevant ?

Another issue we saw some time ago was when one phone had set up a play scenario, the display on another phone still thought the last thing it set up was still valid, when it wasn’t – For example, one track was playing because I’d just asked for it, but the last one Carol had set up still showed as current on her phone.
If the NAS Bubble server updates to all the slaves what it has done, all the 5-7 mobile units will correctly display what is being played.

Could putting BubbleuPnP Server on the NAS achieve this ?
