component	Z-Wave	Instructions how to integrate your existing Z-Wave within Home Assistant.	2015-03-23 19:59	true	false	true	true	z-wave.png	Hub

Z-Wave 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:

$ 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.

# 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:

$ ls /dev/ttyUSB*
