To enable Z-Wave, plug your Z-Wave USB stick into your Raspberry Pi 3 and add the following to your configuration.yaml:

zwave:
  usb_path: /dev/ttyACM0

{% linkable_title RAZBERRY BOARD %}

If you need GPIO on Raspberry Pi 3 for your Z-Wave module, add the following line into config.txt (you have to access that on the SD card directly. Simply plug it into your PC and edit it there. The config.txt is not accessible from your Hass.io system, you may need to open the SD card on a Windows or Linux system.):

dtoverlay=pi3-miniuart-bt

After that, you need to change usb_path to /dev/ttyAMA0 in your configuration.yaml.

zwave:
  usb_path: /dev/ttyAMA0

{% linkable_title HUSBZB-1 %}

zwave:
  usb_path: /dev/ttyUSB0

zha:
  usb_path: /dev/ttyUSB1
  database_path: /config/zigbee.db

{% linkable_title Finding the path %}

If the above defaults don't work, you can check what hardware has been found using the hassio command:

$ hassio hardware info

Or you can use the UI and look in the System section of the Hass.io menu. There you'll find a Hardware button which will list all the hardware found.
