<p>This <code>mqtt</code> sensor platform uses the MQTT message payload as the sensor value. If messages in this <code>state_topic</code> are published with <em>RETAIN</em> flag, the sensor will receive an instant update with last known value. Otherwise, the initial state will be undefined.</p>
|
||
|
||
<p>To use your MQTT sensor in your installation, add the following to your <code>configuration.yaml</code> file:</p>
|
||
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|

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

</div>
|
||
|
||
<p>Configuration variables:</p>
|
||
|
||
<ul>
|
||
<li><strong>state_topic</strong> (<em>Required</em>): The MQTT topic subscribed to receive sensor values.</li>
|
||
<li><strong>name</strong> (<em>Optional</em>): The name of the sensor. Default is ‘MQTT Sensor’.</li>
|
||
<li><strong>qos</strong> (<em>Optional</em>): The maximum QoS level of the state topic. Default is 0.</li>
|
||
<li><strong>unit_of_measurement</strong> (<em>Optional</em>): Defines the units of measurement of the sensor, if any.</li>
|
||
<li><strong>value_template</strong> (<em>Optional</em>): Defines a <a href="/getting-started/templating/">template</a> to extract a value from the payload.</li>
|
||
</ul>
|
||
|
||
<h2><a class="title-link" name="examples" href="#examples"></a> Examples</h2>
|
||
|
||
<p>In this section you find some real life examples of how to use this sensor.</p>
|
||
|
||
<h3><a class="title-link" name="get-battery-level" href="#get-battery-level"></a> Get battery level</h3>
|
||
|
||
<p>If you are using the <a href="components/device_tracker.owntracks/">Owntracks</a> and enable the reporting of the battery level then you can use a MQTT sensor to keep track of your battery. A regular MQTT message from Owntracks looks like this:</p>
|
||
|
||
<div class="highlighter-coderay"><div class="CodeRay">
|
||
<div class="code"><pre>owntracks/tablet/tablet {"_type":"location","lon":7.21,"t":"u","batt":92,"tst":144995643,"tid":"ta","acc":27,"lat":46.12}
|
||
</pre></div>
|
||
</div>
|
||
</div>
|
||
|
||
<p>Thus the trick is extract the battery level from the payload.</p>
