|
||
<p><a href="http://www.z-wave.com/">Z-Wave</a> integration for Home Assistant allows you to observe and control connected Z-Wave devices. Z-Wave support requires a <a href="https://github.com/OpenZWave/open-zwave/wiki/Controller-Compatibility-List">supported Z-Wave USB stick</a> to be plugged into the host.</p>
|
||
|
||
<p>There is currently support for switches, lights and sensors. All will be picked up automatically after configuring this platform.</p>
|
||
|
||
<h3><a class="title-link" name="installation" href="#installation"></a> Installation</h3>
|
||
|
||
<p>To allow Home Assistant to talk to your Z-Wave USB stick you will have to compile the OpenZWave library and install the related <a href="https://github.com/OpenZWave/python-openzwave">python-OpenZWave package</a>. This can be done as follows. <em>(Note: The Home Assistant docker image and the All In One installer have support for Z-Wave already built-in!)</em></p>
|
||
|
||
<p>Make sure you have the correct dependencies installed before running the script:</p>
|
||
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|
||
<div class="code"><pre>$ sudo apt-get install cython3 libudev-dev python3-sphinx python3-setuptools
|
||
</pre></div>
|
||
</div>
|
||
</div>
|
||
|
||
<p>Make sure you have at least version 0.23 of cython.</p>
|
||
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|
||
<div class="code"><pre>$ sudo pip3 install --upgrade cython
|
||
</pre></div>
|
||
</div>
|
||
</div>
|
||
|
||
<p>Then get the OpenZWave files and switch to the <code>python3</code> branch:</p>
|
||
<p class="note warning">Do not use root to build python-openzwave as it will surely fail.</p>
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|
||
<div class="code"><pre>$ git clone https://github.com/OpenZWave/python-openzwave.git
|
||
$ cd python-openzwave
|
||
$ git checkout python3
|
||
$ PYTHON_EXEC=$(which python3) make build
|
||
$ sudo PYTHON_EXEC=$(which python3) make install
|
||
</pre></div>
|
||
</div>
|
||
</div>
|
||
<p class="note">
|
||
Instead of <code>make install</code>, you can alternatively build your own python-openzwave package which can be easily uninstalled:
|
||
|
||
<code>$ sudo PYTHON_EXEC=$(which python3) checkinstall --pkgname python-openzwave --pkgversion 1.0 --provides python-openzwave</code>
|
||
|
||
</p>
|
||
|
||
<p>With this installation, your <code>config_path</code> needed below will resemble:</p>

<p>Configuration variables:</p>
|
||
|
||
<ul>
|
||
<li><strong>usb_path</strong> (<em>Required</em>): The port where your device is connected to your Home Assistant host.</li>
|
||
<li><strong>config_path</strong> (<em>Optional</em>): The path to the Python Open Z-Wave configuration files.</li>
|
||
<li><strong>autoheal</strong> (<em>Optional</em>): Allows disabling auto ZWave heal at midnight. Defaults to True.</li>
|
||
<li><strong>polling_interval</strong> (<em>Optional</em>): 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.</li>
|
||
<li><strong>customize</strong> (<em>Optional</em>): This attribute contains node-specific override values:
|
||
<ul>
|
||
<li><strong>polling_intensity</strong> (<em>Optional</em>): 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.</li>
|
||
</ul>
|
||
</li>
|

<p>To find the path of your Z-Wave stick, run:</p>

<div class="highlighter-coderay"><div class="CodeRay">
|

<div class="code"><pre>$ ls /dev/ttyUSB*
|
||
</pre></div>
|

</div>
|
||
</div>
|
||
|
||
<p>Or, on some other systems (such as Raspberry Pi), use:</p>
|
||
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|
||
<div class="code"><pre>$ ls /dev/ttyACM*

Depending on what’s plugged into your USB ports, the name found above may change. You can lock in a name, such as <code>/dev/zwave</code>, by following <a href="http://hintshop.ludvig.co.nz/show/persistent-names-usb-serial-devices/">these instructions</a>.

<h4><a class="title-link" name="events" href="#events"></a> Events</h4>
|
||
|
||
<p>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):</p>

||
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|

<div class="code"><pre><span class="comment"># Example configuration.yaml automation entry</span>

<p>The <em>entity_id</em> and <em>scene_id</em> of all triggered events can be seen in the console output.</p>
|

<h4><a class="title-link" name="services" href="#services"></a> Services</h4>
|
||
|
||
<p>The Z-Wave component exposes four services to help maintain the network.</p>
|

<table>
|

<th>Service</th>
|

<th>Description</th>
|

</tr>
|
||
</thead>
|
||
<tbody>
|
||
<tr>
|
||
<td>add_node</td>
|
||
<td>Put the zwave controller in inclusion mode. Allows one to add a new device to the zwave network.</td>
|
||
</tr>
|
||
<tr>
|
||
<td>remove_node</td>
|
||
<td>Put the zwave controller in exclusion mode. Allows one to remove a device from the zwave network.</td>
|
||
</tr>
|
||
<tr>
|
||
<td>heal_network</td>
|
||
<td>Tells the controller to “heal” the network. Bascially asks the nodes to tell the controller all of their neighbors so the controller can refigure out optimal routing.</td>
|
||
</tr>
|
||
<tr>
|
||
<td>soft_reset</td>
|
||
<td>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.</td>
|
||
</tr>
|
||
<tr>
|
||
<td>test_network</td>
|
||
<td>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”.</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
|
||
<p>The soft_reset and heal_network commands can be used as part of an automation script<br />
|
||
to help keep a zwave network running relliably. For example:</p>
