Description of problem: I am facing issues with my Sonos integration it seems. This issue occurred after my recent upgrade of HA core. I am wondering if this is a bug in HA, my config or else? Perhaps there is something I can do to assist with debugging of fix it myself?

The issue is reproducible when I use the sonon-card interface to add/join rooms via the room tickbox or the group button I prepared:

The joining/grouping fails and the screen redraws without showing the rooms combined. The browser debug shows the following message:

Please note that when I join/group the rooms via the Sonos app the volume slider IS working and the tick box is set. Volume control is also working now so I can control the device.

"Zithoek" device log shows something strange: "Zithoek changed to Idle triggered by service Media Player: Unjoin" three seconds after the playing starts?

When I search my HA log files for string Sonos I do find one entry:

Subscription renewal failed for Zithoek: Request timed out

Is that the rootcause of my problem? Any suggestion how to fix?

Does join work in the developer page in home assistant?

[simkin]

How does that work exactly? How to initiate the join? (still learning)

[punxaphil]

go to /developer-tools/service (or click "Developer Tools" in the sidebar)

What to select as target?
