There is currently support for climate, covers, lights, locks, sensors, switches and thermostats. All will be picked up automatically after configuring this platform.
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 and the All In One installer have support for Z-Wave already built-in!)
Make sure you have the correct dependencies installed before running the script:
$ sudo apt-get install cython3 libudev-dev python3-sphinx python3-setuptools git
Make sure you have at least version 0.23 and at the most 0.24.1 of cython.
$ sudo pip3 install --upgrade cython==0.24.1
Then get the OpenZWave files and switch to the
Do not use root to build python-openzwave as it will surely fail.
$ 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
make install, you can alternatively build your own python-openzwave package which can be easily uninstalled:
$ sudo apt-get install -y checkinstall $ 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:
If you followed along with setting up a virtual environment, your path will be:
# Example configuration.yaml entry zwave: usb_path: /dev/ttyUSB0
- usb_path (Optional): The port where your device is connected to your Home Assistant host.
- config_path (Optional): The path to the Python OpenZWave configuration files. Defaults to the folder
configin your Python OpenZWave install directory.
- autoheal (Optional): Allows disabling auto Z-Wave heal at midnight. Defaults to True.
- polling_interval (Optional): The time period in milliseconds between polls of a nodes value. Be careful about using polling values below 30000 (30 seconds) as polling can flood the zwave network and cause problems.
- 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). If not specified then your device will not be polled.
- ignored (Optional): Ignore this entitiy completely. It won’t be shown in the Web Interface and no events are generated for it.
- refresh_value (Optional): Enable refreshing of the node value. Only light component uses this. Defaults to 2 second delay.
- delay (Optional): Specify the delay to wait for refresh of node value if you want other than 2 seconds.
To find the path of your Z-Wave USB stick or module, run:
$ ls /dev/ttyUSB*
Or, on some other systems (such as Raspberry Pi), use:
$ ls /dev/ttyACM*
Or, on some other systems (such as Pine 64), use:
$ ls /dev/ttyS*
Or, on macOS, use:
$ ls /dev/cu.usbmodem*
Depending on what’s plugged into your USB ports, the name found above may change. You can lock in a name, such as
/dev/zwave, by following these instructions.
Security Z-Wave devices require a network key before being added to the network using the
zwave.add_node_secure service. You must edit the
options.xml file, located in your
python-openzwave config_path to use a network key before adding these devices.
<!-- <Option name="NetworkKey" value="0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F 0x10" /> -->
Uncomment the line:
<Option name="NetworkKey" value="0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10" />
An easy script to generate a random key:
cat /dev/urandom | tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g'
Home Assistant will trigger a event when the Z-Wave network is complete. Meaning all of the nodes on the network have been queried. This can take quite some time, depending on wakeup intervals on the battery powered devices on the network.
- alias: Z-Wave network is complete trigger: platform: event event_type: zwave.network_complete
Home Assistant will trigger a event when the Z-Wave network is ready for use. Between
zwave.network_ready Home Assistant will feel sluggish when trying to send commands to Z-Wave nodes. This is because the controller is requesting information from all of the nodes on the network. When this is triggered all awake nodes have been queried and sleeping nodes will be queried when they awake.
- alias: Z-Wave network is ready trigger: platform: event event_type: zwave.network_ready
Home Assistant will trigger a event when the Z-Wave network is set up to be started.
- alias: Z-Wave network is starting trigger: platform: event event_type: zwave.network_start
Home Assistant will trigger a event when the Z-Wave network stopping.
- alias: Z-Wave network is stopping trigger: platform: event event_type: zwave.network_stop
Home Assistant will trigger a event when command_class_basic changes value on a node. This can be virtually anything, so tests have to be made to determine what value equals what. You can use this for automations.
- alias: Minimote Button Pressed trigger: platform: event event_type: zwave.node_event event_data: object_id: aeon_labs_minimote_1 basic_level: 255
The object_id and basic_level of all triggered events can be seen in the console output.
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: object_id: zwaveme_zme_wallcs_secure_wall_controller_8 scene_id: 11
The object_id and scene_id of all triggered events can be seen in the console output.
zwave component exposes multiple services to help maintain the network.
|add_node||Put the Z-Wave controller in inclusion mode. Allows one to add a new device to the Z-Wave network.|
|add_node_secure||Put the Z-Wave controller in secure inclusion mode. Allows one to add a new device with secure communications to the Z-Wave network.|
|change_association||Add or remove an association in the Z-Wave network|
|cancel_command||Cancels a running Z-Wave command. If you have started a add_node or remove_node command, and decides you are not going to do it, then this must be used to stop the inclusion/exclusion command.|
|heal_network||Tells the controller to “heal” the Z-Wave network. Basically asks the nodes to tell the controller all of their neighbors so the controller can refigure out optimal routing.|
|remove_node||Put the Z-Wave controller in exclusion mode. Allows one to remove a device from the Z-Wave network.|
|set_config_parameter||Let’s the user set a config parameter to a node.|
|soft_reset||Tells the controller to do a “soft reset”. This is not supposed to lose any data, but different controllers can behave differently to a “soft reset” command.|
|start_network||Starts the Z-Wave network.|
|stop_network||Stops the Z-Wave network.|
|test_network||Tells the controller to send no-op commands to each node and measure the time for a response. In theory, this can also bring back nodes which have been marked “presumed dead”.|
|rename_node||Sets a node’s name. Requires an
heal_network commands can be used as part of an automation script to help keep a Z-Wave network running reliably as shown in the example below. By default, Home Assistant will run a
heal_network at midnight. This is a configuration option for the
zwave component, the option defaults to
true but can be disabled by setting
auto_heal to false. Using the
soft_reset function with some Z-Wave controllers can cause the Z-Wave network to hang. If you’re having issues with your Z-Wave network try disabling this automation.
# Example configuration.yaml automation entry automation: - alias: soft reset at 2:30am trigger: platform: time after: '2:30:00' action: service: zwave.soft_reset - alias: heal at 2:31am trigger: platform: time after: '2:31:00' action: service: zwave.heal_network
