I keep seeing the error below every 30 mins. No visible impact so far.
Not sure but i think it started after I deleted the thing of a device that does no longer exist on my network.
EDIT: restarted OH and now removed that device from the controller, too.
Didn’t happen again so far but will need to wait another 30 mins.
