Sonos: v1 :groups namespaces not supported

Hi,

My Homey setup:

Homey SHS and Homey Bridge.

I have a Sonos Move2 and a IKEA Symfonisk lamp/speaker. When entering the Sonos app in Homey trying to connect the speakers I get the error in the screenshot? Anyone who knows the solution?

Firmware on both speaker and Homey should be up-to-date. And both speakers work in the native Sonos app on iOS.

Edit: In my house (which I took over) there is an Home Assistant installation. I have messed around with it before settling for Homey as primary - and the IKEA speaker was added there and I can find it as an unit in the room where it is placed. But not add it through the sonos app. Could this be the reason?

That seems to be a bug in the Sonos app, you should report it to Athom:

Assuming you are using the official Sonos app for Homey (developed by Athom): there is also an alternative app developed by a community member: Sonos LocalAPI. That app allows you to control your speakers locally; no connection needed to the Sonos-cloud.
