Z-Wave integration for Home Assistant allows you to observe and control connected Z-Wave devices. Z-Wave support requires a supported Z-Wave USB stick to be plugged into the host.
There is currently support for switches, lights and sensors. All will be picked up automatically after configuring this platform.
{% linkable_title Installation %}
To allow Home Assistant to talk to your Z-Wave USB stick you will have to compile the OpenZWave library and install the related python-OpenZWave package. This can be done as follows. (Note: The Home Assistant docker image has support for Z-Wave built-in)
Make sure you have the correct dependencies installed before running the script:
$ apt-get install cython3 libudev-dev python3-sphinx python3-setuptools
Then get the OpenZWave files and switch to the python3 branch:
$ git clone https://github.com/OpenZWave/python-openzwave.git
$ cd python-openzwave
$ git checkout python3
$ PYTHON_EXEC=`which python3` make build
$ sudo PYTHON_EXEC=`which python3` make install
Instead of `make install`, you can alternatively build your own python-openzwave package which can be easily uninstalled:
$ sudo PYTHON_EXEC=which python3 checkinstall --pkgname python-openzwave --pkgversion 1.0 --provides python-openzwave
With this installation, your config_path needed below will resemble:
/usr/local/lib/python3.4/dist-packages/libopenzwave-0.3.0b8-py3.4-linux-x86_64.egg/config
{% linkable_title Configuration %}
# Example configuration.yaml entry
zwave:
usb_path: /dev/ttyUSB0
config_path: /usr/local/share/python-openzwave/config
polling_interval: 10000
customize:
sensor.greenwave_powernode_6_port_energy_10:
polling_intensity: 1
Configuration variables:
- usb_path (Required): The port where your device is connected to your Home Assistant host.
- config_path (Optional): The path to the Python Open Z-Wave configuration files.
- polling_interval (Optional): The time period in milliseconds between polls of a nodes value.
- customize (Optional): This attribute contains node-specific override values:
- polling_intensity (Optional): Enables polling of a value and sets the frequency of polling (0=none, 1=every time through the list, 2-every other time, etc)
To find the path of your Z-Wave stick, run:
$ ls /dev/ttyUSB*
Or, on some other systems (such as Raspberry Pi), use:
$ ls /dev/ttyACM*
Depending on what's plugged into your USB ports, the name found above may change. You an lock in a name, such as `/dev/zwave`, by following [these instructions](http://hintshop.ludvig.co.nz/show/persistent-names-usb-serial-devices/).
{% linkable_title Events %}
Some devices can also trigger scene activation events, which can be used in automation scripts (for example the press of a button on a wall switch):
# Example configuration.yaml automation entry
automation:
- alias: Turn on Desk light
trigger:
platform: event
event_type: zwave.scene_activated
event_data:
entity_id: zwaveme_zme_wallcs_secure_wall_controller_8
scene_id: 11
The entity_id and scene_id of all triggered events can be seen in the console output.
