If i go the oppsite way and open the item first and click on “Add link” i can choose the corresponding Thing but no channels are displayed for it.
This behaviour seems to be apparent for any other Thing i try.
All this has worked before, since i used only the UI for all my links which are currently in place.
The link i need to add now was in principle there before, but due to a re-inclusion of a zwave device i need to re-link the items to a new Thing (new node ID).
All my configurations a re done via Main UI (Items, Link, Thing) except the rules.
My OH3 installation that time back was a complete new installation, just in case that is of interest.
Does anybody know what the problem can be or can support me in narrow further down the cause of this behaviour?
Thanks a lot

If the Channel has a type I think it will only show Items of that type. For example, if the Channel is a switch type Channel, when you go to link it it will only show the Switch Items. It think this changed in OH 4 though as you can use a profile to change the state before it gets to the Item and therefore change the type of Item that the Channel can be linked to.
Do you see a pattern here that fits that description in the Items that it lists?
that is true, the 7 items listed are of the type Contact like the Channel is. Consequently the other way arround, the item i like to link to is of the type DateTime and therfore no channels are shown.
Sorry for obviously not trieng enough
You have answered my original question, but leaves me with the problem that i cannot link the DateTime item to a non matching channel. Yes i did this via Profile, to do the transformation. Here is an example of a other ZWAVE device, where the link is still in place:
Thing - Channel:
There is probably a more elegant way, but I recall having a similar issue some time back (I have a datetime item on every zwave battery channel). I believe I used the “create new item” to set up the datetime and then deleted the old datetime item that was no longer linked to anything.
alright, i changed my existing item first to type Contact linked it to the first Channel and then changed to type Number for the second channel. Finally it was set back to DateTime to be able to apply the Profile.
Not a direct path but a solution! Thanks Rich and Bob for your help. Cheers Henning
