Can the new Z-Wave JS use a Z-Wave controller board that is plugged on the the Raspberry Pi or does it only work with a USB stick?
It works fine for me with the Razberry GPIO board.
What do you use for the path when the install asks for the path to the USB stick?
In my case the device path is /dev/ttyAMA0
When I go to the configuration screen there’s a device path as opposed to usb stick… Make sure you’re on the latest version available as I seem to recall usb stick was what it was called earlier on.
