How can I configure a item as "Liter" in Openhab4


i’ve found this unit of measument concept.

Unfortunately I cannot see how to apply it to my item.

When i set it to Number:Volume i get m³ and i have no idea how to switch it to liters.


Sorry but somehow I guess I miss something here.


I would guess you need to set the unit to:

Type Unit Symbol
Volume Litre l

Yes this seems to be clear after reading the concept.
The question is just where.

Add Unit meta data to the item.

Thx, that did the job
