Unless you have compromising pictures of someone with ZW DB access, adding the device yourself is the norm. The blog here outlines the procedure.
In a nutshell after you register, open a ticket to the developer for write access. Once you have that, upload the XML in your userdata/zwave folder (node??.xml). Then using your manual add the parameters, the documents and association groups and mark for review (on the overview page).
Also of note:
- Not all the multisensor readings are supported (Max is 61).
- if you are on OH3 you will need to download the DB XML when finished and follow this procedure to add it to your binding. Devices are not retroactively added to earlier versions.
