[SOLVED] Help and advice wanted and appreciated: migrated from 3.4.4 to 4.0.2

HWL · August 23, 2023, 9:12am

Hi all,

I am running Openhab on a NAS in a docker environment which is running fine. Nearly all of my items / things are MQTT based. As persistence I use a MySQL database on the same NAS.

This week I prepared the migration from 3.4.4 towards 4.0.x. As advised I added ‘unit’ (UoM) to all items, made a backup of my database and configfiles and even configured a new dockercontainer to which I copied all of the config files (to be able, in case of issues, to rollback easily).

As hoped: the migration went rather smooth. Though not all unit definitions were migrated (didn’t bother to sort out why, the amount was not that large and maybe I missed some of the items since I have nearly 700 of them). Anyway: I found that I made some definitions that weren’t that smart (defining an energy item and then correct that by the state definition since it should be power. Sometimes migrations are a good thing to fix this kind of ‘design issues’).

What’s the issue? When starting openhab, I see in the logs:

I have no clue what is going on. I am used to get some errors while restarting since not all bindings start quick enough, but these errors I have not seen on 3.4.4 (or before). However: I didn’t restart 3.4.4 after adding the units (UoM) and migrating to 4.0.2.

Just to mention: the ‘…’ in the logs are repeating lines I removed.

Could anyone help me how to tackle these? On the other hand: everything is working as expected and there seems to be no issue.

Thanks, best regards,

HWL

These errors have nothing to do with UoM.

It kind of looks like they may have to do with your semantic model. Do you see anything odd in Settings → Model?

HWL · August 23, 2023, 5:04pm

Hi Rich,

Thanks for your response. I was thinking in that direction, but since I didn’t change anything, I didn’t check it out.

I very seldom use the semantic model and now you mention it, I took a look: it’s gone. Since it was there in 3.4.4 I assume there will be an error somewhere in my setup.

How to proceed? Or just start all over? Starting all over isn’t that big an issue (since I was figuring out how to use it), but I would like to get rid of the error message (like to keep my systeem clean and an error or warning should be taken seriously).

??

rlkoshak · August 23, 2023, 5:07pm

The usual suspects include:

Item names that start with a digit
Cyclical Group memberships
One Item being a member of one or more semantically tagged Group

HWL · August 24, 2023, 6:52am

I won’t be asking why it wasn’t an issue before in 3.4.4, or would that make any sense?

From your list, I can exclude points 1 (starting with a digit) and 2 (cyclical) but am pretty sure it is at least 3 (items belonging to more than 1 group).

I did create that since I coupled the thermostats to both a room as well as a general thermostat group.

Can the semantic model be deleted easily or can the issue be found somewhere easy to solve at least the error and start rebuilding the model? Or do I have to walk through all of the items? (I assume I did not do this only with the thermostats).

rlkoshak · August 24, 2023, 1:49pm

The model is implemented by tags on Items and Group membership. It does not exist as a separate thing.

I know of no easy way to find such a problem except to check your Point tagged Items and make sure they are not members of more than one semantically tagged Group. It’s allowed to be members of multiple Groups, but only one of them can have a semantic tag.

HWL · August 25, 2023, 5:54am

Hi Rich, thanks for pointing out. Lots of handwork upcoming I am afraid .

I will start cleaning it and if necessary (error remains) will come back to this thread.

HWL · August 25, 2023, 1:43pm

Hi Rich, deleted all of the tags and the ERROR is gone. Thanks for helping out. Now have to start to recreate the model again.

Still puzzled why this didn’t show up before (on 3.4.4). But anyway: looking forward.

rlkoshak · August 25, 2023, 2:00pm

There were lots and lots of changes to OH between the two. It’s never been supported to have an Item be a member of more than one semantically tagged Group so I would not be surprised if there was a change made somewhere that was made under that assumption.
