<h3>harmony</h3>
<ul>
  Defines a device to integrate a Logitech Harmony Hub based remote control into fhem.<br><br>

  It is possible to: start and stop activities, send ir commands to devices, send keyboard input by bluetooth and
  smart keyboard usb dongles.<br><br>

  Notes:
  <ul>
    <li>JSON has to be installed on the FHEM host.</li>
    <li>For hubs with firmware version 3.x.y &lt;username&gt; and &lt;password&gt; are not required as no authentication
    with the logitech myharmony server is needed for the full functionality of this module.</li>
    <li>For hubs with firmware version 4.x.y &lt;username&gt; and &lt;password&gt; are required for device level control.
    Activit level control is (currently) still possible without authentication.</li>
    <li>activity and device names can be given as id or name. names can be given as a regex and spaces in names musst be replaced by a single '.' (dot).</li>
  </ul><br>
