Why does Sonos have a maximum of 32 Sonos devises in one home? Is there a not so cumbersome work around?

You wouldn't believe the time I spent looking at this question and UPNP documents.

Why?

Well, since 32 is half of 64, and 64 is the size of an unsigned byte, I would guess the total # of controllers (32) and total # of devices (32) are mapped to an array with MAX = unsigned byte.

I have 31 units on WiFi. I have two Roam2’s not on WiFi. In order to up-date the Roam2’s I have to take my Move’s x 2 off WiFi or up-date them one at a time which means I have to break them (Roam2’s) as a stereo pair.

To test the 32 unit limit I put both Roam2’s on WiFi which increased the total unit count to 33. Bad idea 😂. Units started disappearing and reappearing. So yes, 32 units is the limit for Sonos.

It used to be because each device had a limit of 32 items in their UPnP event table - this could be verified as the status pages actually showed the event tables, which was a godsend at the time for me writing UPnP event code. Every Sonos device (including controllers) needs a slot in everyone else’s event tables.

In those days devices had tiny amounts of memory.

No idea if that is still the reason for the limit.
