<p>While the module <a href="#TUL">TUL</a> represents the connection to the KNX network, the KNX modules represent individual KNX devices. This module provides a basic set of operations (on, off, on-until, on-for-timer)
  to switch on/off KNX devices. For numeric DPT you can use value (set &lt;devname&gt; value &lt;177.45&gt;). For string-DPT you can use string (set &lt;devname&gt; string &lt;Hello World&gt;). For other, non-defined 
  dpt you can send raw hex values to the network (set &lt;devname&gt; raw &lt;hexval&gt;).<br> 
  Sophisticated setups can be achieved by combining a number of KNX module instances. Therefore you can define a number of different GAD/DPT combinations per each device.</p>

<p>KNX defines a series of Datapoint Type as standard data types used to allow general interpretation of values of devices manufactured by different companies.
  These datatypes are used to interpret the status of a device, so the state in FHEM will then show the correct value. For each received telegram there will be a reading with state, getG&lt;group&gt; and the sender
  address. For every set, there will be a reading with state and setG&lt;group&gt;.</p>

  <p><a name="KNXdefine"></a> <b>Define</b></p>
  <ul>
    <code>define &lt;name&gt; KNX &lt;group&gt;:&lt;DPT&gt;:&lt[;readingName]&gt; [&lt;group&gt;:&lt;DPT&gt; ..] [IODev]</code>
    
	<p>A KNX device need a concrete DPT. Please refer to <a href="#KNXdpt">Available DPT</a>. Otherwise the system cannot en- or decode the messages. Furthermore you can supply a IO-Device directly at startup. This can be done later on via attribute as well.</p>
	
    <p>Define an KNX device, connected via a <a href="#TUL">TUL</a>. The &lt;group&gt; parameters are either a group name notation (0-15/0-15/0-255) or the hex representation of the value (0-f0-f0-ff).
    All of the defined groups can be used for bus-communication. Without further attributes, all incoming messages are translated into state. Per default, the first group is used for sending. If you want to send
	via a different group, you have to index it (set &lt;devname&gt; value &lt;17.0&gt; &lt;g2&gt;).<br>
	If you use the readingName, readings are based on this name (e.g. hugo-set, hugo-get for name hugo).</p>

    <p>The module <a href="#autocreate">autocreate</a> is creating a new definition for any unknown sender. The device itself will be NOT fully available, until you added a DPT to the definition. The name will be
	KNX_nnmmooo where nn is the line adress, mm the area and ooo the device.</p>

    <p>Example:</p>
      <pre>
      define lamp1 KNX 0/10/12:dpt1
      define lamp1 KNX 0/10/12:dpt1:meinName 0/0/5:dpt1.001
      define lamp1 KNX 0A0C:dpt1.003 myTul
      </pre>

	One hint regarding dpt1 (binary): all the sub-types have to be used with keyword value. Received telegrams are already encoded to their representation. This mechanism does not work for send-telegrams.
	Here on/off has to be supplied.<br>
	Having the on/off button (for send values) without keyword value is an absolutely special use-case and only valid for dpt1 and its sub-types.<br>
	
    <p>Example:</p>
      <pre>
      define rollo KNX 0/10/12:dpt1.008
	  set rollo value off
	  set rollo value on
      </pre>
	
  </ul>
  
  <p><a name="KNXset"></a> <b>Set</b></p>
  <ul>
    <code>set &lt;name&gt; &lt;on, off&gt;</code> [g&lt;groupnr&gt;]
	<code>set &lt;name&gt; &lt;on-for-timer, on-until&gt; &lt;time&gt; [g&lt;groupnr&gt;]</code>
	<code>set &lt;name&gt; &lt;value&gt; [g&lt;groupnr&gt;]</code>
	<code>set &lt;name&gt; &lt;string&gt; [g&lt;groupnr&gt;]</code>
	<code>set &lt;name&gt; &lt;raw&gt; [g&lt;groupnr&gt;]</code>
	
    <p>Example:</p>
    <pre>
      set lamp1 on
      set lamp1 off
      set lamp1 on-for-timer 10
      set lamp1 on-until 13:15:00
      set foobar raw 234578
      set thermo value 23.44
	  set message value Hallo Welt
    </pre>

	<p>When as last argument a g&lt;groupnr&gt; is present, the command will be sent
	to the KNX group indexed by the groupnr (starting by 1, in the order as given in define).</p>
	<pre>
      define lamp1 KNX 0/10/01:dpt1 0/10/02:dpt1
      set lamp1 on g2 (will send "on" to 0/10/02)
	</pre>

	<p>A dimmer can be used with a slider as shown in following example:</p>
	<pre>
      define dim1 KNX 0/0/5:dpt5.001
      attr dim1 slider 0,1,100
      attr dim1 webCmd value
	</pre>
	
	<p>The current date and time can be sent to the bus by the following settings:</p>
	<pre>
      define timedev KNX 0/0/7:dpt10
      attr timedev webCmd value now
      
      define datedev KNX 0/0/8:dpt11
      attr datedev webCmd value now
      
      # send every midnight the new date
      define dateset at *00:00:00 set datedev value now
      
      # send every hour the current time
      define timeset at +*01:00:00 set timedev value now
	</pre>	
  </ul>
 
  <p><a name="KNXget"></a> <b>Get</b></p>
  <ul>  
  <p>If you execute get for a KNX-Element the status will be requested a state from the device. The device has to be able to respond to a read - this is not given for all devices.<br>
	The answer from the bus-device is not shown in the toolbox, but is treated like a regular telegram.</p>

  <p><a name="KNXformat"></a> <b>format</b></p>
  <ul> 
	The content of this attribute is added to every received value, before this is copied to state.
      <p>Example:</p>
      <pre>
      define myTemperature KNX 0/1/1:dpt5
      attr myTemperature format &degC;
      </pre>
  </ul> 

  <p><a name="KNXstateRegex"></a> <b>stateRegex</b></p>
  <ul> 
    You can pass n pairs of regex-pattern and string to replace, seperated by a slash. Internally the "new" state is always in the format getG&lt;group&gt;:&lt;state-value&gt;. The substitution is done every time, 
	a new object is received. You can use this function for converting, adding units, having more fun with icons, ... 
	This function has only an impact on the content of state - no other functions are disturbed. It is executed directly after replacing the reading-names and setting the formats, but before stateCmd
      <p>Example:</p>
      <pre>
      define myLamp KNX 0/1/1:dpt1 0/1/2:dpt1 0/1/2:dpt1
      attr myLamp stateRegex /getG1:/steuern:/ /getG2:/status:/ /getG3:/sperre:/ /setG[13]:/steuern:/ /setG[3]://
	  attr myLamp devStateIcon status.on:general_an status.off:general_aus sperre.on:lock steuern.*:hourglass
      </pre>    
  </ul>	

  <p><a name="KNXstateCmd"></a> <b>stateCmd</b></p>
  <ul>
	You can supply a perl-command for modifying state. This command is executed directly before updating the reading - so after renaming, format and regex. 
	Please supply a valid perl command like using the attribute stateFormat.
	Unlike stateFormat the stateCmd modifies also the content of the reading, not only the hash-conten for visualization.
      <p>Example:</p>
      <pre>
      define myLamp KNX 0/1/1:dpt1 0/1/2:dpt1 0/1/2:dpt1
      attr myLamp stateCmd {$state = sprintf("%s", ReadingsVal($name,"getG2","undef"))}
      </pre>    
  </ul>

  <p><a name="KNXanswerReading"></a> <b>answerReading</b></p>
  <ul> 
    If enabled, FHEM answers on read requests. The content of state is send to the bus as answer.
    <p>If set to 1, read-requests are answered</p>
  </ul>

  <p><a name="KNXlistenonly"></a> <b>listenonly</b></p>
  <ul> 
	If set to 1, the device may not send any messages. As well answering requests although get is prohibited.
  </ul>	 

  <p><a name="KNXreadonly"></a> <b>readonly</b></p>
  <ul> 
	If set to 1, the device may not send any messages. Answering requests are prohibited.Get is allowed.
  </ul>	 

  <p><a name="KNXslider"></a> <b>slider</b></p>
  <ul> 
	slider &lt;min&gt;,&lt;step&gt;,&lt;max&gt;<br>
	With this attribute you can add a slider to any device. 
      <p>Example:</p>
      <pre>
      define myDimmer KNX 0/1/1:dpt5
      attr myDimmer slider 0,1,100
	  attr myDimmer webCmd value
      </pre>
  </ul>  

  <p><a name="KNXdpt"></a> <b>DPT - datapoint-types</b></p>
  <ul>  
  <p>The following dpt are implemented and have to be assigned within the device definition.</p>

<h3>KNX</h3>
<ul>
<p>KNX ist ein Standard zur Haus- und Geb&auml;udeautomatisierung.
  Der Standard begr&uuml;ndet sich haupts&auml;chlich auf twisted pair, findet aber auch zunehmende Verbreitung auf andere Medien (Funk, Ethernet, ...)</p>
  F&uuml;r Anf&auml;nger sei folgende Lekt&uuml;re empfohlen: <a href="http://www.knx.org/media/docs/Flyers/KNX-Basics/KNX-Basics_de.pdf">KNX-Basics</a>

<p>Das Modul <a href="#TUL">TUL</a> stellt die Verbindung zum Bus her, Das KNX-Modul stellt die Verbindung zu den einzelnen KNX-/EIB-Ger&auml;ten her. Das Modul stellt Befehle (on, off, on-until, on-for-timer)
  zum ein- und Ausschalten von Ger&auml;ten zur Verf&uuml;gung. F&uuml;r numerische DPT nutzt bitte value (set &lt;devname&gt; value &lt;177.45&gt;). F&uuml;r string-DPT nutzt bitte string 
  (set &lt;devname&gt; string &lt;Hello World&gt;). F&uuml;r andere, undefinierte DPT k&ouml;nnt Ihr raw hex Werte ans Netzwerk senden (set &lt;devname&gt; raw &lt;hexval&gt;).<br> 
  Komplexe Konfigurationen k&ouml;nnen aufgebaut werden, indem mehrere Modulinstanzen in einem Ger&auml;t definiert werden. Daf&uuml;r werden mehrere Kombinationen aus GAD und DPT in einem Ger&auml;t definiert werden.</p>

<p>Der KNX-Standard stellt eine Reihe vordefinierter Datentypen zur Verf&uuml;gung. Dies sichert die Hersteller&uuml;bergreifende Kompatibilit&auml;t.
  Basierend auf diesen DPT wird der Status eines Ger&auml;tes interpretiert und in FHEM angezeigt. F&uuml;r jedes empfangene Telegramm wird ein reading mit state, getG&lt;group&gt; und der Absenderadresse angelegt.
  F&uuml;r jedes ser-command wird ein Reading mit state und setG&lt;group&gt; angelegt.</p>

  <p><a name="KNXdefine"></a> <b>Define</b></p>
  <ul>
    <code>define &lt;name&gt; KNX &lt;group&gt;:&lt;DPT&gt;:&lt[;readingName]&gt; [&lt;group&gt;:&lt;DPT&gt; ..] [IODev]</code>
    
	<p>Ein KNX-device ben&ouml;tigt einen konkreten DPT. Bitte schaut die verf&uuml;gbaren DPT unter <a href="#KNXdpt">Available DPT</a> nach. Wird kein korrekter DPT angegeben, kann das system die Nachrichten nicht korrekt de- / codieren. 
	Weiterhin kann bei der Ger&auml;tedefinition eine IO-Schnittstelle angegeben werden. Dies kann sp&auml;ter ebenfalls per Attribut erfolgen.</p>
	
    <p>Jedes Device muss an eine <a href="#TUL">TUL</a> gebunden sein. Die &lt;group&gt; Parameter werden entweder als Gruppenadresse (0-15/0-15/0-255) oder als Hex-notation angegeben (0-f0-f0-ff).
    Alle definierten Gruppen k&ouml;nnen f&uuml;r die Buskommunikation verwendet werden. Ohne weitere Attribute, werden alle eingehenden Nachrichten in state &uuml;bersetzt. 
	Per default wird &uuml;ber die erste Gruppe gesendet.<br>
	Wenn Ihr einen readingNamen angebt, wird dieser als Basis für die Readings benutzt (z.B. hugo-set, hugo-get for name hugo).<br>
	Wollt Ihr &uuml;ber eine andere Gruppe senden. m&uuml;sst Ihr diese indizieren (set &lt;devname&gt; value &lt;17.0&gt; &lt;g2&gt;).</p>
	
    <p>Das Modul <a href="#autocreate">autocreate</a> generiert eine Instanz f&uuml;r jede unbekannte Gruppenadresse. Das Ger&auml;t selbst wird jedoch NICHT korrekt funktionieren, so lange noch kein korrekter 
	DPT angelegt ist. Der Name ist immer KNX_nnmmooo wobei nn die Linie ist, mm der Bereich und ooo die Geräteadresse.</p>

    <p>Example:</p>
      <pre>
      define lamp1 KNX 0/10/12:dpt1
      define lamp1 KNX 0/10/12:dpt1:meinName 0/0/5:dpt1.001
      define lamp1 KNX 0A0C:dpt1.003 myTul
      </pre>
	  
	Ein Hinweis bezüglich dem binären Datentyp dpt1: alle Untertypen müssen über das Schlüsselwort value gesetzt werden. Empfangene Telegramme werden entsprechend ihrer Definition automatisch
	umbenannt. Zu sendende Telegramme sind immer min on/off zu belegen!<br>
	Die zur Verfügung stehenden on/off Schaltflächen ohne den Schlüssel value sind ein absoluter Sonderfall und gelten für den dpt1 und alle Untertypen.
	
    <p>Example:</p>
      <pre>
      define rollo KNX 0/10/12:dpt1.008
	  set rollo value off
	  set rollo value on

  <p><a name="KNXformat"></a> <b>format</b></p>
  <ul> 
	Der Inhalt dieses Attributes wird bei jedem empfangenen Wert angehangen, bevor der Wert in state kopeiert wird.
      <p>Example:</p>
      <pre>
      define myTemperature KNX 0/1/1:dpt5
      attr myTemperature format &degC;
      </pre>
  </ul> 

  <p><a name="KNXstateRegex"></a> <b>stateRegex</b></p>
  <ul> 
	Es kann eine Reihe an Search/Replace Patterns &uuml;bergeben werden (getrennt durch einen Slash). Intern wird der neue Wert von state immer im Format getG&lt;group&gt;:&lt;state-value&gt;. abgebildet. 
	Die Ersetzungen werden bei bei jedem neuen Telegramm vorgenommen. Ihr k&ouml;nnt die Funktion f&uuml;r Konvertierungen nutzen, Einheiten hinzuf&uuml;gen, Spaß mit Icons haben, ...
	Diese Funktion wirkt nur auf den Inhalt von State - sonst wird nichts beeinflusst.
	Die Funktion wird direkt nach dem Ersetzen der Readings-Namen und dem ergänzen der Formate ausgeführt.
      <p>Example:</p>
      <pre>
      define myLamp KNX 0/1/1:dpt1 0/1/2:dpt1 0/1/2:dpt1
	  attr myLamp stateRegex /getG1:/steuern:/ /getG2:/status:/ /getG3:/sperre:/ /setG[13]:/steuern:/ /setG[3]://
	  attr myLamp devStateIcon status.on:general_an status.off:general_aus sperre.on:lock steuern.*:hourglass
      </pre>    
  </ul>	
 
  <p><a name="KNXstateCmd"></a> <b>stateCmd</b></p>
  <ul>
	Hier könnt Ihr ein perl-Kommando angeben, welches state beeinflusst. Die Funktion wird unmittelbar vor dem Update des Readings aufgerufen - also nach dem Umbennenen der Readings, format und regex.
	Es ist ein gültiges Perl-Kommando anzugeben (vgl. stateFormat). Im Gegensatz zu StateFormat wirkt sich dieses Attribut inhaltlich auf das Reading aus, und nicht "nur" auf die Anzeige im FHEMWEB.
      <p>Beispiel:</p>
      <pre>
      define myLamp KNX 0/1/1:dpt1 0/1/2:dpt1 0/1/2:dpt1
      attr myLamp stateCmd {$state = sprintf("%s", ReadingsVal($name,"getG2","undef"))}
      </pre>    
  </ul>

  <p><a name="KNXanswerReading"></a> <b>answerReading</b></p>
  <ul> 
	Wenn aktiviert, antwortet FHEM auf Leseanfragen. Der Inhalt von state wird auf den Bus gelegt.
    <p>Leseanfragen werden beantwortet, wenn der Wert auf 1 gesetzt ist.</p>
  </ul>

  <p><a name="KNXlistenonly"></a> <b>listenonly</b></p>
  <ul> 
	Wenn auf 1 gesetzt, kann das Ger&auml;t keine Nachrichten senden. Sowohl Leseanfragen als auch get sind verboten.
  </ul>	 

  <p><a name="KNXreadonly"></a> <b>readonly</b></p>
  <ul> 
	Wenn auf 1 gesetzt, kann das Ger&auml;t keine Nachrichten senden. Leseanfragen sind verboten. Get ist erlaubt.
  </ul>	 

  <p><a name="KNXslider"></a> <b>slider</b></p>
  <ul> 
	slider &lt;min&gt;,&lt;step&gt;,&lt;max&gt;<br>
	Mit diesem Attribut k&ouml;nnt Ihr jedem Ger&auml;t einen Slider verpassen.
      <p>Example:</p>
      <pre>
      define myDimmer KNX 0/1/1:dpt5
      attr myDimmer slider 0,1,100
	  attr myDimmer webCmd value
      </pre>
  </ul>
