<p>The <code class="highlighter-rouge">template</code> platform supports sensors which breaks out the state and <code class="highlighter-rouge">state_attributes</code> from other entities.</p>
|
||
|
||
<p>To enable Template binary sensors in your installation, add the following to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
|
||
|
||
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>

<p>Configuration variables:</p>
|
||
|
||
<ul>
|
||
<li><strong>sensors</strong> array (<em>Required</em>): List of your sensors.
|
||
<ul>
|
||
<li><strong>friendly_name</strong> (<em>Optional</em>): Name to use in the Frontend.</li>
|
||
<li><strong>sensor_class</strong> (<em>Optional</em>): The <a href="/components/binary_sensor/">type/class</a> of the sensor to set the icon in the frontend.</li>
|
||
<li><strong>value_template</strong> (<em>Optional</em>): Defines a <a href="/topics/templating/">template</a> to extract a value from the payload.</li>
|
||
<li><strong>entity_id</strong> (<em>Optional</em>): Add a list of entity IDs so the sensor only reacts to state changes of these entities. This will reduce the number of times the sensor will try to update it’s state.</li>

<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="sensor-threshold" href="#sensor-threshold"></a> Sensor threshold</h3>
|
||
|
||
<p>This example indicates true if a sensor is above a given threshold. Assuming a sensor of <code class="highlighter-rouge">furnace</code> that provides a current reading for the fan motor, we can determine if the furnace is running by checking that it is over some threshold:</p>

|
||
<span class="s">value_template</span><span class="pi">:</span> <span class="pi">{{</span> <span class="nv">states.sensor.furnace.state > 2.5</span> <span class="pi">}}</span>

|
||
<h3><a class="title-link" name="switch-as-sensor" href="#switch-as-sensor"></a> Switch as sensor</h3>
|
||
|
||
<p>Some movement sensors and door/window sensors will appear as a switch. By using a template binary sensor, the switch can be displayed as a binary sensors. The original switch can then be hidden by <a href="/getting-started/customizing-devices/">customizing.</a></p>
