The first error might be because no XML was pasted in. The second error is normally because this is a new manufacturer (I’m guessing it is LS Control 0x0071) that has to be added. You can open a ticket and include the XML. Only the developer @chris can add that, after it is added, you should be good to go.
There could also be an error for other reasons like a duplicate device, but I’m guessing not, since I assume you already tried to include in OH and are using the XML generated in the userdata/zwave folder. You could check this by using the TYPE:ID hex pair in the search field, something like 0004:035d or whatever.
I would agree that undeleting the device would be the best solution. I don’t know if anyone out in the world would be using OH with that device and would be relying on that db entry to be there even if it’s been subsequently deleted.
Google has very little information about the device and i’ve not been able to find a manual, but there is a page here that has some information.
If you do undelete, add a note saying that the sync button is inside the case, and to open the case you need to pop off the little plastic bump on the top to gain access to the screw which holds the thing together.
