# 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
#
# Published under GNU GPL License, v2
#
# Date		   Who				Comment																												   
# ----------  -------------   	-------------------------------------------------------------------------------------------------------------------------------
# 2016-01-30  RaspII			Now also Blinds and Switches are implemented (all actuators I have). 
# 2016-01-12  RaspII			Implemented Dimmer Commands for 1&3 key remote, removed toggle	
# 2015-06-02  RaspII			Now can also Handle multiple devices with same code, next step: implement all commands (on, off, toggle... for KOPP_FC_Parse)
#								Missing is also 2 key commands (e.g. key1=on Key2=off for Dimmmers, key1=up key2=down for blinds)
# 2015-05-21  RaspII			Beim FS20 Modul sind die möglichen Set Commands abhängig vom "model" Attribute !! hier weitersuchen
#								Seit die Return SerExtensions eingebaut ist, lässt sich bei Taste2Rad4 dass Commando Off nicht mehr absetzen (hat was mit dem Modul SerExtensions zu tun)
# 2015-05-02  RaspII			Try now to receive Kopp Messages, also
# 2015-04-13  RaspII 			Modified some typos (help section)
# 2015-02-01  RaspII			use small "k" to start Kopp FW, "K" was already used for raw data
# 2014-12-21  RaspII			V6 (fits to my FHEM.cfg V6) Removed timeout from define command, will add later to set command (best guess yet). 
# 2014-12-13  RaspII			first version with command set: "on, off, toggle, dim, stop". Added new Parameter ("N" for do not print) 
# 2014-12-08  RaspII			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  RaspII			first Version

<h3>Kopp Free Control protocol</h3>
<ul>
  <b>Please take into account: this protocol is under construction. Commands may change </b>
  <br><br>

  The Kopp Free Control protocol is used by Kopp receivers/actuators and senders.
  This module is able to send commands to Kopp actuators and receive commands from Kopp transmitters. Currently supports devices: dimmers, switches and blinds.
  The communication is done via 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" and "attr CUL_0 rfmode KOPP_FC" ).

  <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; [&lt;Keycode2&gt] [&lt;Keycode3&gt]</code>
 
  <br>
   <br><li><code>&lt;name&gt;</code></li>
   name is the identifier (name) you plan to assign to your specific device (actuator) 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>Both codes (Transmittercode1/2) are also used to pair the transmitter with the receivers (remote switch, dimmer, blind..)
  
   <br><br><li><code>[&lt;Keycode2&gt;]</code></li>
   Keycode2 is an opional 2 digit hex code (1Byte) which reflects a second transmitters key
  
   <br><br><li><code>[&lt;Keycode3&gt;]</code></li>
   Keycode3 is an opional 2 digit hex code (1Byte) which reflects a third transmitters key
   <br>
   Some receivers like dimmers can be paired with two addional keys, which allow to switch the dimmer directly on or off.
   That means FHEM will always know the current state, which is not the case in one key mode (toggling between on and off)
   
   <br><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 (or two, see dimmer above) 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 the receiver from FHEM, the receiver handles FHEM just linke another remote control.
</ul>         

  <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>dimm</code><br>
	<code>stop</code><br>
	</ul>    
	
    <pre>Examples:
    <code>set DimmerDevice on</code> 		# will toggle dimmer device (e.g. lamp) on/off
    <code>set DimmerDevice dimm</code> 		# will start dimming process
    <code>set DimmerDevice stop</code>       	# will stop dimming process
   	</pre>
  </ul>
  <br> 

  <a name="KOPP_FCattrib"></a>
  <b>Attributes</b>
  <ul>
    <code>attr CUL_0 rfmode KOPP_FC</code> 
    <br>
  	
	This attribute will switch the Kopp protocol on for device CUL_0<br>
	You can not use a second protocol on this device
    
  </ul>
  <br>
  
  <br><br>Example: FHEM Config for Dimmer via 1 Key remote control:
  <ul>
      <code>define Dimmer KOPP_FC 65 FA5E 02</code><br>
	  <code>attr Dimmer IODev CCD</code><br>
	  <code>attr Dimmer devStateIcon OnOff:toggle:dimm dimm:dim50%:stop stop:on:dimm off:toggle:dimm</code><br>
	  <code>attr Dimmer eventMap on:OnOff dimm:dimm stop:stop</code><br>
	  <code>attr Dimmer group Dimmer_1KeyMode</code><br>
  	  <code>attr Dimmer model Dimm_8011_00</code><br>
	  <code>attr Dimmer room Test</code><br>
	  <code>attr Dimmer webCmd OnOff:dimm:stop</code><br>
  </ul>
