So, I’ve begun transition from OH2->OH3 and I’m building my semantic model:
I defined
Attic
2nd Floor
Office
Master
Etc
1st Floor
Living Room
Dining Room
Etc
Basement
Outside
I then put into each room the appropriate equipment. When I defined one piece of equipment, I accidentally put it into the wrong room on the first floor, so I went to edit it, got some errors and reloaded the page, now my “First Floor” and all of the rooms in it are missing on the semantic model page, but still exists on the Locations page:
Thanks for the quick reply. I guess I don’t know where to do this. In the Semantic model, the first floor doesn’t appear at all, so there is nothing to click on. Is there somewhere else this might appear?
You can find the missing First Floor Group Item there.
It might work to click the “show non-semantic” at the bottom of the Model page. If the Group still exists and is just missing the semantic tag it should show up after checking that box.
OK, assuming you’ve not done anything else since this started happening the easiest thing we can do to get you back to good is to restore from the automatic the backups.
Stop openHAB.
Navigate to $OH_USERDATA/jsondb/backup (e.g. /var/lib/openhab/jsondb/backup).
Identify the backup file that was taken right around the time that the problem first started happening for org.openhab.core.items.Item.json by looking at the timestamps on the files. It will likely be the most recent one.
Double check the ownership and permissions on the file you just copied. Then restart openHAB. That will undo what ever happened to cause the current JSONDB file to be corrupted.
If you are curious you can open the corrupted file (it’s just text) and look for something fishy. Though that will only tell you what, not how or why.
