    Consumes HomeBus telemetry for a single <code>PA-44Z</code> smoke detector endpoint and projects it to HomeKit services.

  </p>

  <p>

    Output 3 controls a Node-RED <code>mqtt in</code> node with dynamic subscriptions.

  </p>

  <p>

    On start, the node emits:

    <code>subscribe &lt;site&gt;/home/&lt;location&gt;/+/&lt;accessory&gt;/last</code>,

    <code>subscribe &lt;site&gt;/home/&lt;location&gt;/+/&lt;accessory&gt;/value</code>, and

    <code>subscribe &lt;site&gt;/home/&lt;location&gt;/+/&lt;accessory&gt;/availability</code>.

  </p>

  <p>

    The node keeps <code>.../last</code> subscribed until bootstrap is held open for <code>10s</code>, then emits a complete snapshot and unsubscribes from <code>.../last</code>.

  </p>

  <h3>Capabilities</h3>

  <p>

    Mappings:

    <code>smoke -&gt; Smoke Sensor</code>,

    <code>battery + battery_low -&gt; Battery</code>,

    <code>device_fault -&gt; StatusFault</code>.

  </p>

  <p>

    <code>silence</code>, <code>test</code>, and <code>smoke_concentration</code> are carried on HomeBus but are not exposed to HomeKit by this adapter.

  </p>

  <h3>Outputs</h3>

  <ol>

    <li>Smoke Sensor: <code>{ SmokeDetected, StatusActive, StatusFault, StatusLowBattery }</code></li>

    <li>Battery Service: <code>{ StatusLowBattery, BatteryLevel, ChargingState }</code></li>

    <li><code>mqtt in</code> dynamic control messages: <code>{ action, topic }</code></li>

  </ol>

  <h3>HomeKit Service Setup</h3>
