# Kopp Free Control protocol module for FHEM
# (c) Claus M.
#
# This modul is currenly under construction and will only work if you flashed your CCD device with hexfile from: 
# svn+ssh://raspii@svn.code.sf.net/p/culfw/code/branches/raspii/culfw/Devices/CCD/CCD.hex
# which includes support for "K" command

# Date		   Who				Comment																												   
# ----------  -------------   	-------------------------------------------------------------------------------------------------------------------------------
# 2014-12-21  Claus M.			V6 (fits to my FHEM.cfg V6) Removed timeout from define command, will add later to set command (best guess yet). 
# 2014-12-13  Claus M.			first version with command set: "on, off, toggle, dim, stop". Added new Parameter ("N" for do not print) 
# 2014-12-08  Claus M.			direct usage of set command @ FHEM.cfg works fine, but buttoms on/off do not appear, seems to be a setup/initialize issue in this routine 
# 2014-09-01  Claus M.			first Version

<h3>Kopp Free Control protocol</h3>
<ul>
  <b>Please take into account: this protocol is under construction. Commands may change till first official "10_KOPP_FC.pm" version is released</b>
  <br><br>

  The Kopp Free Control protocol is used by Kopp receivers/actuators and senders.
  As we right now are only able to send Kopp commands but can't receive them, this module currently only
  supports devices like dimmers, switches and in futue also blinds through a <a href="#CUL">CUL</a> or compatible device (e.g. CCD...). 
  This devices must be defined before using this protocol (e.g. "define CUL_0 CUL /dev/ttyAMA0@38400 1234" ).

  <br><br>
  <a name="KOPP_FCdefine"></a>
  <b>Define</b>
  <ul>
  <code>define &lt;name&gt; KOPP_FC &lt;Keycode&gt; &lt;Transmittercode1&gt; &lt;Transmittercode2&gt;</code>
 
  <br>
   <br><li><code>&lt;name&gt;</code></li>
   name is the identifier (name) you plan to assign to your specific device (actor) as done for any other FHEM device
   
   <br><br><li><code>&lt;Keycode&gt;</code></li>
   Keycode is a 2 digit hex code (1Byte) which reflects the transmitters key
  
   <br><br><li><code>&lt;Transmittercode1&gt;</code></li>
   Transmittercode1 is a 4 digit hex code. This code is specific for the transmitter itself.
   
   <br><br><li><code>&lt;Transmittercode2&gt;</code></li>
   Transmittercode2 is a 2 digit hex code and also specific for the transmitter, but I didn't see any difference while modifying this code.
   (seems this code don't matter the receiver). 
   
   <br><br>Both codes (Transmittercode1/2) are also used to pair the transmitter with the receivers
   <br>(remote switch, dimmer, blind..)
   <br>
   Pairing is done by setting the receiver in programming mode by pressing the program button at the receiver<br>
   (small buttom, typically inside a hole).<br>
   Once the receiver is in programming mode send a command from within FHEM to complete the pairing.
   For more details take a look to the data sheet of the corresponding receiver type.
   <br>
   You are now able to control teh receiver from FHEM, the receiver thinks it is just another remote control.
              
     
   
   <br><br>Examples:
   <ul>
      <code>define DimmerDevice KOPP_FC 65 FA5E 02</code><br>
      <code>define DimmerDevice KOPP_FC 30 FA5E 02</code><br>
    </ul>
  </ul>
  <br>

  <a name="KOPP_FCset"></a>
  <b>Set</b>
  <ul>

    <code>set &lt;name&gt; &lt;value&gt</code>
    <br>
 
   <br><li><code>&lt;value&gt;</code></li>
	value is one of:
    <ul>
    <code>on</code><br>
	<code>off</code><br>
	<code>stop</code><br>
	<code>toggle</code><br>
	<code>dimm</code><br>
	</ul>    
	
    <pre>Examples:
    <code>set DimmerDevice toggle</code> 		# will switch dimmer device (e.g. lamp) on/off
    <code>set DimmerDevice dimm</code> 		# will start dimming process
    <code>set DimmerDevice stopp</code>       	# will stop dimming process
   	</pre>
  </ul>
  <br>
  
 </ul>
