Description of Issue

I have another thread open, where Roon keeps losing all of my Sonos devices.

This issue relates to adding a Sonos device. I have added another Play:1 which is recognised and available in Sonos but after rebooting the Core several times Roon doesn’t find the new device

Closing in favor of the other thread below.

Sonos system keeps disconnecting

It’s been stable for a few days now, running on the headless Mac mini. Has anything changed at Roon as nothing has changed here - for example, does Roon auto update software? I have ordered a new router to replace the BT Home Hub (although this brings it’s own problems as using a non BT router means I will lose my home landline phone, if you can believe it!) and I will wire the Mac Mini direct to the new router.
