I found the solution (NUT-Plugin): [ugreenups] driver = usbhid-ups port = auto vendorid = 2b89 productid = ffff subdriver = Arduino desc = "Ugreen US3000 via USB"
The little UPS is really cute and works great with UGOS. In Unraid I have activated it as APC and USB. But unfortunately it is not recognized. Has anyone managed to fix this?
