<p>The <code>proximity</code> component allows you to monitor the proximity of devices to a particular <a href="/components/zone/">zone</a> and the direction of travel. The result is an entity created in Home Assistant which maintains the proximity data.</p>
<p>This component is useful to reduce the number of automation rules required when wanting to perform automations based on locations outside a particular zone. The <a href="/components/automation/#zone-trigger">zone</a> and <a href="/components/automation/#state-trigger">state</a> based triggers allow similar control but the number of rules grows exponentially when factors such as direction of travel need to be taken into account.</p>
<p>Some examples of its use include:</p>
<ul>
<li>Increase thermostat temperature as you near home</li>
<li>Decrease temperature the further away from home you travel</li>
</ul>
<p>The Proximity entity which is created has the following values:</p>
<ul>
<li><code>state</code>: Distance from the monitored zone (in km)</li>
<li><code>dir_of_travel</code>: Direction of the closest device to the monitoed zone. Values are:
<ul>
<li>not set</li>
<li>arrived</li>
<li>towards</li>
<li>away_from</li>
<li>unknown</li>
<li>stationary</li>
</ul>
</li>
<li><code>dist_to_zone</code>: Distance from the monitored zone (in km)</li>
</ul>
<p>To enable this component 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">proximity</span>:

<p>Configuration variables:</p>
<ul>
<li><strong>zone</strong> (<em>Optional</em>): The zone to which this component is measuring the distance to. Default is the home zone.</li>
<li><strong>ignored_zones</strong> array (<em>Optional</em>): Where proximity is not calculated for a device (either the device being monitored or ones being compared (e.g. work or school).</li>
<li><strong>devices</strong> array (<em>Optional</em>): A list of devices to compare location against to check closeness to the configured zone.</li>
<li><strong>tollerance</strong> (<em>Optional</em>): The tolerance used to calculate the direction of travel in meters (m) to filter out small GPS coordinate changes.</li>
