So was able to Raspberry Pi with Z-Wave JS UI, and adding the keys from the addon did the trick for Z-Wave JS UI to recognize the USB stick and all the paired devices,
now I’m stuck in step 4 of the instructions you posted, and when adding the Z-Wave integration, I uncheck the “Use the Z-Wave JS Supervisor add-on” ,
when I put the Raspberry Pi pi “ws://rapberry.ip:3000” I get “Failed to connect” and I can’t figure out why, no error message
I checked Raspberry Pi and did " lsof -i -P -n | grep LISTEN" and I can see that port 3000 is open
so now I’m trying to figure out why it can’t connect
