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

```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):

```
dtoverlay=pi3-miniuart-bt
```

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

```yaml
zwave:
  usb_path: /dev/ttyAMA0
```

### {% linkable_title HUSBZB-1 %}

```yaml
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/commandline/#hardware):

```bash
$ 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.
