    <h3>Inputs</h3>
    <dl class="message-properties">
        <dt>payload
            <span class="property-type">object</span>
        </dt>
        <dd>
            When the message contains a <code>sid</code> field, the node will filter the input and output only if the <code>sid</code> is the device's sid.<br>
            <hr>
            If the message doesn't contain a <code>sid</code> field, the node will be used to inject <code>sid</code> and <code>gateway</code> fields in the incoming <code>msg</code>.<br>
            <hr>
            Input Gateway node produces message of type <code>read_ack</code>, <code>heartbeat</code> or <code>report</code>.
        </dd>
    </dl>

    <h3>Outputs</h3>
    <ol class="node-ports">
        <dl class="message-properties">
            <dt>payload <span class="property-type">object</span></dt>
            <dd>Data from gateway when used as a filter (see below).</dd>

            <dd>The <code>xiaomi-configurator</code> object where the device is registred.</dd>
        </dl>
    </ol>

    <h4>Details</h4>
    <p>The incoming message is processed if the input <code>sid</code> matches the configured value for this device.</p>
    <p>Sample message:</p>
    <p><pre>{
  cmd: "read_ack"
  model: "sensor_magnet.aq2"
  sid: "158d000112fb5d"
  short_id: 50301
  data: {
    voltage: 3015,
    status: "close",
    batteryLevel: 23
  }
}</pre>
Where <code>status</code> can be <code>"open"</code> or <code>"close"</code>, <code>batteryLevel</code> is a computed percentage of remaining battery.
