This topic can be used to discuss problems/experiences/questions on the openHAB 5.0 release as announced in this topic .

I’m not so sure this is an OpenHab 5.0 release issue. I have had this issue for years now (probably since Ubuntu 22.04, but definitely since 24.04, running OpenHab 4.x)., and I think it appeared after an Ubuntu upgrade, not an OpenHab update. I’d probably agree with @mstormi that this is worthy of…

I wasn’t looking for it, so maybe it’s been going on for quite some time, indeed. I’ll make a separate issue. But in which subforum…?

Strangely not all links of my MQTT-items were broken. Did this happen to someone else as we…
