I am using Openhab insid a docker container (with host networking) on a arm device to control my KNX system. This is working fine, but the four Sonos things go offline after some time, maybe an hour or so. Doing a restart bundle:restart org.jupnp in karaf console let the come back online. When online, I am able to control them and their status with OH.
I put my Sonos devices into a seperate network / vlan for security reasons. As Sonos is using multicast for communication, I configured a igmp proxy on my unify equipment (https://durdle.com/2018/12/09/unifi-vlans-sonos-and-igmp-proxy). This is working, sonos apps on Windows, Android and iOS does not see any difference. Also a test install with home assistant is able to control sonos, even after a runtime of 3 days. Only in OH they get offline after some time.
As it seems that I am the only user with this problem I suppose its caused by this non standard setup.
Does somebody have an advice how to throubleshoot this? I dont have any java skills.
It’s not just you; it’s been happening to me for over 9+ months now. I’ve tried everything and nothing seems to completely cure it. I do have a normal setup (OH on a Synology (no docker), everything on the same subnet, using SonosNet and some hardwired, etc.)
I have also tried numerous version of the Sonos binding - same results.
I’m running the latest Sonos patch level across 14 Sonos devices. All of mine comprise of Amps and Sonos 1’s which some are in pairs.
