Or you can also just buy an usb based aoetech z-stick or similar and use that 
instead, for example on a pi.
It is already working well with zwavejs2mqtt plus home assistant and doesn't 
need any hw/sw hacking to get it working so probably less effort but of course 
costs a little compared to something you might already have.
