Haseman R4D4 driver?

Haseman R4D4 is a nice little DIN box: 4 dimmers + 4 switches in a single box; both cost- and space-effective. Does anyone know if it is compatible, has tried it, or know of a community-driver? I've seen that @AdamV has created drivers for their relay controllers - did you see anything for the R4D4 during your work?

Hello

I bought one to try it, can only det one relay to work when adding it as a generic z-wave switch.
Also tried the Universal Z-wave parent driver (this works with another DIN relay I have) but cannot get it to work with R4D4.

No ideas on how to make it work, so guess it goes to the box on the shelf with the other stuff.
