The rpi_gpio sensor platform allows you to read sensor values of the GPIOs of your <a href="https://www.raspberrypi.org/">Raspberry Pi</a>.</p>
|
|
|
|
<p>To use your Raspberry Pi’s GPIO in your installation, add the following to your <code>configuration.yaml</code> file:</p>
|
|
|
|
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
|
|
<span class='line-number'>2</span>
|
|
<span class='line-number'>3</span>
|
|
<span class='line-number'>4</span>
|
|
<span class='line-number'>5</span>
|
|
<span class='line-number'>6</span>
|
|
<span class='line-number'>7</span>
|
|
<span class='line-number'>8</span>
|
|
<span class='line-number'>9</span>
|
|
</pre></td><td class='code'><pre><code class=''><span class='line'># Example configuration.yaml entry
|
|
</span><span class='line'>sensor:
|
|
</span><span class='line'> platform: rpi_gpio
|
|
</span><span class='line'> pull_mode: "UP"
|
|
</span><span class='line'> value_high: "Active"
|
|
</span><span class='line'> value_low: "Inactive"
|
|
</span><span class='line'> ports:
|
|
</span><span class='line'> 11: PIR Office
|
|
</span><span class='line'> 12: PIR Bedroom</span></code></pre></td></tr></table></div></figure>
|
|
|
|
|
|
<p>For more details about the GPIO layout, visit the Wikipedia <a href="https://en.wikipedia.org/wiki/Raspberry_Pi#GPIO_connector">article</a> about the Raspberry Pi.</p>
|
|

|
<p class='note warning'>
|
|
As this requires access to the GPIO, you will need to run Home Assistant as root.
