Troubleshooting Your Configuration
</h1>
</header>
<hr class="divider">
<p>It can happen that you run into trouble while configuring Home Assistant. A component is not
showing up or is acting weird. This page will discuss a few of the most common problems.</p>
<p>Before we dive into common issues, make sure you know where your configuration directory is.
Home Assistant will print out the configuration directory it is using when starting up.</p>
<p>Whenever a component or configuration option results in a warning, it will be stored in
<code>home-assistant.log</code>. This file is reset on start of Home Assistant.</p>
<h3><a class='title-link' name='yaml' href='#yaml'></a> YAML</h3>
<p>Home Assistant uses the YAML syntax for configuration. YAML can be confusing at start but it is really
powerful in allowing you to express complex configurations.</p>
<p>The basics of YAML are lists and lookup tables containing key-value pairs. Lists will have each item
start with a <code>-</code> while lookup tables will have the format <code>key: value</code>. The last value for a key is
used in case you specify a duplicate key.</p>

<p>Indentation is used to specify which objects are nested under one anohter. Getting the right indentation
can be tricky if you&rsquo;re not using an editor with a fixed width font. You can test your
configuration using <a href="http://yaml-online-parser.appspot.com/">this online YAML parser</a>.</p>
<p>To learn more about the quirks of YAML, read
<a href="https://docs.saltstack.com/en/latest/topics/troubleshooting/yaml_idiosyncrasies.html">YAML IDIOSYNCRASIES</a>
by SaltStack.</p>
<h3><a class='title-link' name='my-component-does-not-show-up' href='#my-component-does-not-show-up'></a> My component does not show up</h3>
<p>When a component does not show up, many different things can be the case. Before you try any of
these steps, make sure to look at the <code>home-assistant.log</code> file and see if there are any errors
related to your component you are trying to set up.</p>
<p><strong>Problems with the configuration<br></strong>
<code>configuration.yaml</code> does not allow multiple sections to have the same name. If you want a
specific component to be loaded twice, append a number to the name.</p>

</span><span class='line'> <span class="p-Indicator">[</span><span class="nv"></span><span class="p-Indicator">]</span>
</span></code></pre></td></tr></table></div></figure>
<p>Another common problem is that a required configuration setting is missing. If this is the
case, the component will report this to <code>home-assistant.log</code>. You can have a look at
<a href="/components/">the component page</a> for instructions how to setup the components.</p>
<p>If you find any errors or want to expand the documentation, please
<a href="https://github.com/balloob/home-assistant.io/issues">let us know</a>.</p>
<p><strong>Problems with dependencies<br></strong>
Almost all components have external dependencies to communicate with your devices and services.
Sometimes Home Assistant is unable to install the necessary dependencies. If this is the case, it
should show up in <code>home-assistant.log</code>.</p>
<p>First step is trying to restart Home Assistant and see if the problem persists. If it does, please
<a href="https://github.com/balloob/home-assistant/issues">report it</a> so we can investigate what is going on.</p>
<p><strong>Problems with components<br></strong>
It can happen that some components either do not work right away or stop working after Home
Assistant has been running for a while. If this happens to you, please
<a href="https://github.com/balloob/home-assistant/issues">report it</a> so that we can have a look.</p>
<p class='note'>
Whenever you report an issue, be aware that we are a group of volunteers that do not have access to
every single device in the world nor unlimited time to fix every problem out there.
