after updating my openhab docker image to 2.3.0 I found that auto discovers finds all my homematic things again, but with a different id, which worries me a bit.
When I added the newly discovered things I ended up with all of my things duplicated, the new things having a different id as the “old” ones. Of course the new things weren’t linked to anything, which is why they did not work, but the old ones still did as before.
I found out that I also had the CCU bridge duplicated the “old” one appears as
with the serial number “MEQ1491XXX” in its properties
whereas the “new” (both are same physically) one appears as
eQ3-HM-CCU2-App - 192.168.XXX.XXX
After deleting all the duplicated things, they of course showed up in discovery again, but after deleting the “new” bridge as well, the disappear (which makes sense to me if the bridge is deleted)
I can overcome this problem by just hiding the discovered new bridge in discovery.
It seems to me that the homematic binding was changed somehow to now use the serial number of the CCU2 as the id as opposed to using something else before.
Besides that it is a bit annoying being careful not accept the duplicated bridge, I am wondering if I need to do something about this? Could I be running into problems with later updates?
I do not want to change all my things manually to the new bridge definition to have them all with the new ids, since, having 50+ homematic things, I not only have to update alle the things, but also recreate the 150+ links to their items.
Has anyone else stumbled upon this behaviour?
I’ll attach a screenshot where I have added to of the new things that got duplicated to show what I mean:
