[Z-Wave](http://www.z-wave.com/) support for Home Assistant is very new. We have started now by integrating only the sensors.

Support for Z-Wave can be added by plugging a Z-Wave USB stick into your computer.

To allow Home Assistant to talk to your Z-Wave USB stick you will have to compile `Python Open Z-Wave` yourself. We have made it easy and added a script that will do just that for you: `script/build_python_openzwave`.

Please make sure you have the correct dependencies installed:

```bash
$ apt-get install cython3 libudev-dev python-sphinx python3-setuptools
$ pip3 install "cython<0.23"
```

As an alternative, the Home Assistant docker image has support for Z-Wave built-in.

```yaml
# Example configuration.yaml entry
zwave:
  usb_path: /dev/ttyUSB0
```

Configuration variables:

- **usb_path** (*Required*): The port where your device is connected to your Home Assistant host.

To find the path of your Z-Wave stick, run:

```bash
$ ls /dev/ttyUSB*
```
