Raspberry PI GPIO sensor

<hr class="divider">
<p>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&rsquo;s GPIO in your installation, add the following to your <code>configuration.yaml</code> file:</p>
<pre><code class="yaml"># Example configuration.yaml entry
sensor:
platform: rpi_gpio
ports:
11: PIR Office
12: PIR Bedroom
pull_mode: "UP"
value_high: "Active"
value_low: "Inactive"
</code></pre>
<p>Configuration variables:</p>
<ul>
<li><strong>ports</strong> array (<em>Required</em>): Array of used ports.
<ul>
<li><strong>port: name</strong> (<em>Required</em>): Your username for the Edimax switch.</li>
</ul>
</li>
<li><strong>pull_mode</strong> (<em>Optional</em>): The internal pull to use (UP or DOWN). Default is UP.</li>
<li><strong>value_high</strong> (<em>Optional</em>): The value of the sensor when the port is HIGH. Default is &ldquo;HIGH&rdquo;.</li>
<li><strong>value_low</strong> (<em>Optional</em>): The value of the sensor when the port is LOW. Default is &ldquo;LOW&rdquo;.</li>
<li><strong>bouncetime</strong> (<em>Optional</em>): The time in milliseconds for port debouncing. Default is 50ms.</li>
</ul>
<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'>
If you are not running Raspbian Jessie, you will need to run Home Assistant as root.
</p>
<p class='note warning'>
To avoid having to run Home Assistant as root when using this component, run a Raspbian version released at or after September 29, 2015.
