Strange warning regarding type conversion coming from Shelly binding

Setup, Configuration and Use Beginners
1

Hello, I’m just looking through all the logs - and I find this warning here:

19:57:11.231 WARN org.openhab.core.library.items.NumberItem
Failed to update item 'Shelly_Heizung_shellypro1pmec62608abd4419216810242_Stromstarke' because '0.533 A' could not be converted to the item unit 'V'

I don’t quite understand the message, because I would interpret it to mean that the Shelly Binding delivers ‘0.533 A’ here - but openHAB obviously wants it in volts.
The channel is defined (by the binding, not by me!) as Number:ElectricPotential >Measurement > Current - and there are no special settings for the item itself.

What has happened - and what can I do to prevent this from happening again?

Note: I have around 40 Shelly’s installed in the house - and that’s the only device that’s making trouble. Thank you!

The Channel is defined as Number:ElectricCurrent and the default unit for that is indeed A.

Your Item is defined as Number:ElectricPotential and the default unit for that is V.

Your Item needs to be Number:ElectricCurrent, not Number:ElectricPotential.

When using “create equipment from thing”, “add equipment to model”, “add points to model”, or create new Item when linking the Channel, the correct Item type should be configured automatically.

What process did you use to create this Item and link it to the Channel?

Can’t remember to be honest, but I changed the type and now the error is gone. Thank you for your help!
