<p>The dht sensor platform allows you to get the current temperature and humidity from a DHT11, DHT22, or AM2302 device.</p>
|
||
|
||
<p>To use your DHTxx 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.yaml entry</span>
|

<span class="key">sensor</span>:
|
||
<span class="key">platform</span>: <span class="string"><span class="content">dht</span></span>
|
||
<span class="key">sensor</span>: <span class="string"><span class="content">DHT22</span></span>
|
||
<span class="key">pin</span>: <span class="string"><span class="content">23</span></span>
|

<span class="key">monitored_conditions</span>:
|

|

</pre></div>
|

</div>
|

</div>
|
||
|
||
<p>Configuration variables:</p>
|
||
|
||
<ul>
|
||
<li><strong>sensor</strong> (<em>Required</em>): The sensor type, supported devices are DHT11, DHT22, and AM2302</li>
|
||
<li><strong>pin</strong> (<em>Required</em>): The pin the sensor is connected to.</li>
|
||
<li><strong>monitored_conditions</strong> array: Conditions to monitor.
|
||
<ul>
|
||
<li><strong>temperature</strong>:</li>
|
||
<li><strong>humidity</strong>:</li>
|
||
</ul>
|
||
</li>
|
||
</ul>
|
||
|
||
<p>Available conditions are only <em>temperature</em> and <em>humidity</em>.</p>
|
||
|
||
<p>The name of the pin to which the sensor is connected has different names on different platforms. ‘P8_11’ for Beaglebone, ‘23’ for Raspberry Pi.</p>
|
||
|
||
<p class="note warning">
|
||
As this requires access to the GPIO, you will need to run Home Assistant as root.
