Entity Component Platform Options
</h1>
</header>
<hr class="divider">
<p>Any component that is based on the entity component allows various extra options to be set per platform.</p>
<h3><a class="title-link" name="entity-namespace" href="#entity-namespace"></a> Entity namespace</h3>
<p>By setting an entity namespace, all entities will be prefixed with that namespace. That way <code class="highlighter-rouge">light.bathroom</code> can become <code class="highlighter-rouge">light.holiday_house_bathroom</code>.</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>
<span class="s">light</span><span class="pi">:</span>
<span class="s">platform</span><span class="pi">:</span> <span class="s">hue</span>
<span class="s">entity_namespace</span><span class="pi">:</span> <span class="s">holiday_house</span>
</code></pre>
</div>
<h3><a class="title-link" name="scan-interval" href="#scan-interval"></a> Scan Interval</h3>
<p>Platforms that require polling will be polled in an interval specified by the main component. For example a light will check every 30 seconds for a changed state. It is possible to overwrite this scan interval for any platform that is being polled by specifying a <code class="highlighter-rouge">scan_interval</code> config key. In the example below we setup the Philips Hue lights but tell Home Assistant to poll the devices every 10 seconds instead of the default 30 seconds.</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry to poll Hue lights every 10 seconds.</span>
<span class="s">light</span><span class="pi">:</span>
<span class="s">platform</span><span class="pi">:</span> <span class="s">hue</span>
<span class="s">scan_interval</span><span class="pi">:</span> <span class="s">10</span>
