Eddystone Beacon
</h1>
</header>
<hr class="divider">
<p>The <code class="highlighter-rouge">eddystone_temperature</code> sensor platform reads temperature information from Bluetooth LE advertisements transmitted by <a href="https://en.wikipedia.org/wiki/Eddystone_(Google)">Eddystone</a> beacons. Your beacons must be configured to transmit UID frames (for identification) and TLM frames (for temperature).
All beacons that support the Eddystone protocol, have a temperature sensor and can transmit TLM frames are compatible with this platform. For example <a href="https://store.gimbal.com/collections/beacons/">Gimbal</a>, <a href="http://estimote.com/">Estimote</a> or <a href="https://kontakt.io/">kontakt.io</a>. For more manufacturers see <a href="https://developers.google.com/beacons/eddystone#beacon_manufacturers">this overview</a> by Google.</p>
<h2>Requirements</h2>
<p>As this platform uses <code class="highlighter-rouge">bluez</code> to scan for Bluetooth LE devices <strong>a Linux OS with bluez installed</strong> is required. In addition to that, the <code class="highlighter-rouge">libbluetooth</code> headers need to be installed:</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo apt-get install libbluetooth-dev
</code></pre>
</div>
<p>Scanning for Bluetooth LE devices also requires special permissions. To grant these to the python executable execute the following:</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo apt-get install libcap2-bin
<span class="gp">$ </span>sudo setcap <span class="s1">'cap_net_raw,cap_net_admin+eip'</span> <span class="k">$(</span>readlink -f <span class="k">$(</span>which python3<span class="k">))</span>
</code></pre>
</div>
<p>To use your Eddystone beacon 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>
<span class="s">sensor</span><span class="pi">:</span>

<p>Configuration variables:</p>
<ul>
<li><strong>bt_device_id</strong> (<em>Optional</em>): The id of the bluetooth device that should be used for scanning (hci<em>X</em>). You can find the correct one using <code class="highlighter-rouge">hcitool dev</code> (default: 0).</li>
<li><strong>beacons</strong> array (<em>Required</em>): The beacons that should be monitored.
<ul>
<li><strong>[entry]</strong> (<em>Required</em>): Name of the beacon.
<ul>
<li><strong>namespace</strong> (<em>Required</em>): Namespace ID of the beacon in hexadecimal notation. Must be exactly 20 characters (10 bytes) long.</li>
<li><strong>instance</strong> (<em>Required</em>): Instance ID of the beacon in hexadecimal notation. Must be exactly 12 characters (6 bytes) long.</li>
<li><strong>name</strong> (<em>Optional</em>): Friendly name of the beacon.</li>
