Temporary UoM error when adding Item to a Group

[mboremski]

I added a Shelly EM3 to my Things and created the corosponding items. They where working fine for some days, also with persistence.

Than I decidet to sort my new items a bit more in groups. I created a group insidemy already existend model and acalled it Energy:

When i than added my items to the new group the UoM seem to fail:

This is only happening until the next item-update comes in. After the next value comes from my shelly this gets back to normal.

This is not a big dealfor items that update often. Some Items only update once everyday what may confuse people.

That is a curious effect, may be UI related. Worth using API Explorer to examine the actual state of an Item while display is in "Err" state.

Do you see something like Exception while formatting value '{}' of item {} with format '{}': {} in the log? It should be logged at WARN level. I can't reproduce the issue with latest code.
