<h3>HMLAN</h3>
<ul>
  <tr><td>
  The HMLAN is the fhem module for the eQ-3 HomeMatic LAN Configurator.
  <br><br>
  The fhem module will emulate a CUL device, so the <a href="#CUL_HM">CUL_HM</a>
  module can be used to define HomeMatic devices.<br><br>

  In order to use it with fhem you <b>must</b> disable the encryption first
  with the "HomeMatic Lan Interface Configurator" (which is part of the
  supplied Windows software), by selecting the device, "Change IP Settings",
  and deselect "AES Encrypt Lan Communication".<br><br>
  This device can be used in parallel with a CCU and (readonly) with fhem. To do this:
  <ul>
    <li>start the fhem/contrib/tcptee.pl program
    <li>redirect the CCU to the local host
    <li>disable the LAN-Encryption on the CCU for the Lan configurator
    <li>set the dummy attribute for the HMLAN device in fhem
  </ul>
  <br><br>

  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; HMLAN &lt;ip-address&gt;[:port]</code><br>
    <br>
    port is 1000 by default.
    If the ip-address is called none, then no device will be opened, so you
    can experiment without hardware attached.<br>
