Yes, it is the same in OH2. For me with remoteopenhab looking at an OH2 Docker container on the same host it is really annoying. I set the Thing to use the local ip address of the host but the Inbox finds the Docker address which can change for every reboot.
I’d agree that this is a bug. My Harmony Hub and OpenWeatherMap things keep reappearing after reboots, so it seems as if the ignored history is not being retained.
It doesn’t bother me, since I’m rarely in the inbox.
Since it seems to affect some items but not others, it’s more likely a bug in the respective bindings that causes them to rediscover the ignored items.
I found that for me also unexpectedly some other items (even from other bindings) show up as ignored instead of the ones I did ignore. Is that also the case for you?
Just want to throw in that it happens here the same way. Randomly ignoring things, but not binding specific. I had all things ignored “except” the shelly yesterday
