I have this error on my log every now and then.

2022-05-22 09:31:32.070 [WARN ] [ab.core.internal.events.EventHandler] - Dispatching event to subscriber 'org.openhab.core.internal.items.ItemUpdater@f0e993' takes more than 5000ms.

How can I know wich item is not updating?

I coudn’t find anything on the forums or the doc.

Thanks in advance.

It’s not likely to be about a single Item, this is more a symptom of a performance issue. The thing complaining about not getting resource (cpu time) is not the thing that is hogging the resource.

Review your system setup with an eye to performance bottelenecks in the first case. What is your filestore media? How many Items do you have? What persistence have you configured? Got any high-throughput bindings in use?

I had this issue also before I switched from micro SD card to SSD. Adn yes I know… SSDs are not offcial supported by openhabian but I would never switch back again…
