Zwave trouble


I installed HASS on an RPI3 with Raspbian light using the AIO script. When trying to initialize the Open-Zwave usb stick I get:

What am I doing wrong ? The Open-zwave stick is working fine on my Ubuntu machine.

Are you sure you’ve got the correct usb_path: in your config? Depending on your PI and the particular USB slot that you inserted the controller into, that can change. With RPI3’s, you’ll have /dev/ttyACMX - but X can change if you plug into a different port.

This command will tell you which port you’ve got:
ls /dev/ttyACM*

path is correct. Found another post suggesting I should stop HASS before trying to initialize the zwave-stick. Will try that when I’m home. Thnx for the reply.

Oh. Yeah. That. If HASS is on, it holds access to the device.
