Sonos devices keep toggling ONLINE/ERROR:COMM

Updated my openhabian setup to openHAB 5.1. My sonos devices keep toggling ONLINE / ERROR:COMM. Rolled back to 5.0.3 and my speakers are stable ONLINE.

Did a fresh install of openhab 5.1 on a barebone Ubuntu 24.04.3 LTS server, installed the sonos add-on, same problem. My sonos devices keep toggling ONLINE / ERROR:COMM.

5.0.3:

5.1.0:

And what is the error ?

I did some further testing as my speakers were added via a things-file with a refresh set to 1 second. As it was for years…. without problems.

I changed the refresh rate to 60 seconds (the default when adding the speaker from the inbox.). Seems to work fine (for) now.

I mark this as solution… Thanks for the fast reply.

Setting this parameter to 1s makes no sense as it floods your Sonos devices with requests … for no reason.

Trying to understand how you could have made such strange decision, I checked the description of this parameter and I was surprised to discover that it doesn’t describe what this parameter is for.

Yes, now I know. I thought the refresh parameter was the interval the values of the channels were read from the devices…
