<p>The <code>configuration.yaml</code> file contains the configuration options for components and platforms. To ensure that the given configuration provided by the user is valid we use <a href="https://pypi.python.org/pypi/voluptuous">voluptuous</a> to check it. Certain entries are optional or could be required for the setup of a platform or a component. Others must be of a certain type or out of an already defined list. This will ensure that the users are notified if something is wrong with a platform or component setup before Home Assistant is running.</p>
|
||
|
||
<p>Beside the <a href="https://pypi.python.org/pypi/voluptuous">voluptuous</a> default types are a bunch of custom types available. To get a full overview take a look at the <a href="https://github.com/home-assistant/home-assistant/blob/master/homeassistant/helpers/config_validation.py">config_validation.py</a> helper.</p>
|
||
|
||
<ul>
|
||
<li>Types: <code>string</code>, <code>byte</code>, and <code>boolean</code></li>
|
||
<li>Entity ID: <code>entity_id</code> and <code>entity_ids</code></li>
|
||
<li>Numbers: <code>small_float</code> and <code>positive_int</code></li>
|
||
<li>Time: <code>time</code>, <code>time_zone</code></li>
|
||
<li>Misc: <code>template</code>, <code>slug</code>, <code>temperature_unit</code>, <code>latitude</code>, <code>longitude</code>, <code>isfile</code>, <code>sun_event</code>, <code>ensure_list</code>, and <code>icon</code></li>
|
||
</ul>
|
||
|
||
<p>To validate plaforms using <a href="/components/mqtt/">MQTT</a> there are <code>valid_subscribe_topic</code> and <code>valid_publish_topic</code> present.</p>
|
||
|
||
<p>Some things to keep in mind:</p>
|
||
|
||
<ul>
|
||
<li>Use the constants which are definded in <code>const.py</code>.</li>
|
||
<li>Import <code>PLATFORM_SCHEMA</code> from parent component and extend it.</li>
|
||
<li>Preferred order is <code>required</code> first, then <code>optional</code>.</li>
|
||
</ul>
