<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="json-attributes-configuration" href="#json-attributes-configuration"></a> JSON attributes configuration</h3>
<p>The example sensor below shows a configuration example which uses JSON in the state topic to add extra attributes. It also makes use of the availability topic. Attributes can then be extracted in <a href="configuration/templating/#attributes">Templates</a>; Example to extract data from the sensor below ‘{{ states.sensor.bs_client_name.attributes.ClientName }}’.</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>
