<p>The easiest way to get started with <code>haco</code> is to define a simple device and run the client.</p>
<h1 id="installation">Installation</h1>
<p><code>haco</code> can be installed via pip:</p>
<div class="language-bash highlight"><pre><span></span><code>pip<span class="w"> </span>install<span class="w"> </span>haco
</code></pre></div>
<div class="admonition tip">
<p class="admonition-title">MQTT Broker Required</p>
<p><code>haco</code> communicates with Home Assistant via MQTT. Ensure you have an MQTT broker (like Mosquitto) running and accessible.</p>
</div>
<h1 id="basic-usage">Basic Usage</h1>
<p>Here is a minimal example that creates a device with a single button:</p>

<li><strong>Discovery</strong>: When the script runs, it sends discovery messages to Home Assistant.</li>
<li><strong>Entity Created
   </strong>: A new device named "My Cool Device" will appear in Home Assistant with a button entity named "My Awesome Button".</li>
<li><strong>Control</strong>: When you press the button in the Home Assistant UI,
   <code>haco</code> will receive the command. You can then handle this command in your Python script by overriding the
   <code>command</code> method or providing a callback (see <a href="../controls/">Control Types</a> for more details).</li>
