I made a new subnet for my 6 Sonos player runing on 192.168.20.1. It has the Vlan nummber 20 and everything seamth to work exept of beeing visible on my openhab system. This is runing on 192.168.1.109 with docker on my synology nas.
I do have a
USG 3P - 188.8.131.5287926 Switch US-16-150W - 184.108.40.20625 Two AP UAP-AC-Pro - 220.127.116.1125
My Sonos are Play 1 S1 11.2.3
The Problem is, that openhab can’t realy see my sonos players anymore and this is a known problem. In the openhab binding for Sonos it tels that I have to change the TTL.
Attention: You might run into trouble if your control system (the binding) is in another subnet than your Sonos device. Sonos devices make use of multicast which in most cases needs additional router configuration outside of a single subnet. If you observe communication errors (COMMUNICATION_ERROR/not registered), you might need to configure your router to increase the TTL of the packets send by your Sonos device. This happens because of a TTL=1 for ALIVE packets send by Sonos devices, resulting in dropped packets after one hop.
Thanks verymuch for the help
