HTTP Binary Sensor
</h1>
</header>
<hr class="divider">
<p>The URL for a binary sensor looks like the example below:</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>http://IP_ADDRESS:8123/api/states/binary_sensor.DEVICE_NAME
</pre></div>
</div>
</div>
<p class="note">
You should choose a unique device name (DEVICE_NAME) to avoid clashes with other devices.
</p>
<p>The JSON payload must contain the new state and can have a friendly name. The friendly name is used in the frontend to name the sensor.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>{<span class="key"><span class="delimiter">&quot;</span><span class="content">state</span><span class="delimiter">&quot;</span></span>: <span class="string"><span class="delimiter">&quot;</span><span class="content">on</span><span class="delimiter">&quot;</span></span>, <span class="key"><span class="delimiter">&quot;</span><span class="content">attributes</span><span class="delimiter">&quot;</span></span>: {<span class="key"><span class="delimiter">&quot;</span><span class="content">friendly_name</span><span class="delimiter">&quot;</span></span>: <span class="string"><span class="delimiter">&quot;</span><span class="content">Radio</span><span class="delimiter">&quot;</span></span>}}
</pre></div>
</div>
</div>
<p>For a quick test <code>curl</code> can be useful to “simulate” a device.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ curl -X POST -H &quot;x-ha-access: YOUR_PASSWORD&quot; \
-d '{&quot;state&quot;: &quot;off&quot;, &quot;attributes&quot;: {&quot;friendly_name&quot;: &quot;Radio&quot;}}' \
http://localhost:8123/api/states/binary_sensor.radio
</pre></div>
</div>
</div>
<p>To check if the sensor is working, use again <code>curl</code> to retrieve the <a href="/developers/rest_api/#get-apistatesltentity_id">current state</a>.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ curl -X GET -H &quot;x-ha-access: YOUR_PASSWORD&quot; \
http://localhost:8123/api/states/binary_sensor.radio
{
&quot;attributes&quot;: {
&quot;friendly_name&quot;: &quot;Radio&quot;
},
&quot;entity_id&quot;: &quot;binary_sensor.radio&quot;,
&quot;last_changed&quot;: &quot;16:45:51 05-02-2016&quot;,
&quot;last_updated&quot;: &quot;16:45:51 05-02-2016&quot;,
&quot;state&quot;: &quot;off&quot;
}
</pre></div>
</div>
</div>
<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. Beside <code>curl</code>.</p>
<h3><a class="title-link" name="using-python-request-module" href="#using-python-request-module"></a> Using Python request module</h3>
<p>As already shown on the <a href="/developers/rest_api/">API</a> page, its very simple to use Python and the <a href="http://docs.python-requests.org/en/latest/">Requests</a> module for the interaction with Home Assistant.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>response = requests.post(
