    Defines a device connected to a <a href="#Aurora">Aurora</a>.<br><br>

    The device status will be updated every &lt;interval&gt; seconds. 0 means no updates.
    Groups are updated only on definition and statusRequest<br><br>

    Examples:
    <ul>
      <code>define aurora Aurora 10.0.1.xxx 10</code><br>
    </ul>
  </ul><br>

  <a name="Aurora_Readings"></a>
  <b>Readings</b>
  <ul>
    <li>bri<br>
    the brightness reported from the device. the value can be betwen 1 and 254</li>
