You have strong perseverance! I recognize a lot of the frustration from when I first started using openHAB.
I don’t use ZWave devices myself. But out of curiosity I had a look.
Your DeviceID is most definetely added to the database. The 6501:000b device ID is added to the References (Type:Id) on the database website. Also I see that these changes were committed to the code base about 3 days ago.
I also see that you recently did a succesful reinstall. Does the device get properly recognized now that you are most likely using a newer build of openHAB?
