I’ve migrated from OH2.5 to 3 on a new system.
After the setup i switched the main system and copied the item persistence files to OH3.
In my sitemaps with chats the old and new written persistence Data is shown but in the OH3 schematics UI when I select an Item only the data written on the new system is shown.
Some additional information that could help to find the problem:
I first copied the rrd4j.persist but as this overwrites the standard OH3 setup I deleted (renamed it for now) it and since then all items are saved.
With the old config the sitemap charts also worked and the new UI didn’t not even for the items set in the config.
No the affected Items were all copied with their .item files.
I copied the .rrd files to /var/lib/openhab/persistence/rrd4j
like described here: OH 3 migration of historical persistence data
Also first copied the rrd4j.persit file to /etc/openhab/persistence , later deleting it to use the default OH3 behavior and getting the new UI working at all.
This was the old rrd4j.persit config:
Ok, it seems to be an error / misunderstanding on my site.
The items affected are defined in .items files.
Items from these files cannot be added in the Semantic Model??
Add point from thing will create a new item and not use the already existing one.
Is there any way to use the items from the .items files in the model?
I would like to keep using the files for the ease of use.
