[SOLVED] Strange Error for GroupItem - GenericItemProvider

Hi threre,

When resetting oH I always get the error message below concerning the group “Gtest”

openhab Cannot add "GroupItem" with key "Gtest". It exists already from provider "GenericItemProvider"! Failed to add a second with the same UID from provider "GenericItemProvider"!

Could someone please explain the meaning and maybe how to solve.


Try cleaning the cache and see if that helps.

sudo systemctl stop openhab2

sudo openhab-cli clean-cache

sudo systemctl start openhab2

By way of explanation, it is trying to add an Item named Gtest when one already exists. Maybe you have both PaperUI and xxx.items file definitions, or in more than onexxx.items file, etc.

In deed - this group was in two items files.
