To add to a device to an OH4.3 version your zwave jar needs to be modified to add this file

in a folder named hoppe using this method Update ZWave binding with new/updated device xml - Tutorials & Examples - openHAB Community.
One area of uncertainty for me is there is no hoppe folder in OH4.x, but I’m thinking if you can create one it will still work. (most vendors already have a folder, but this is the first device from hoppe).
I have also had success using edit functions in a compressed file editor to accomplish this task, but it doesn’t seem to be able to add folders.
