  <b>Color: HSV compared to RGB</b>
  <p>
    Normally, a color may be expressed in the HSV color space as well as in RGB color space.
  <p>
    Colors in the HSV color space usually seem more understandable. 
    To move a Green in the HSV color space a little more toward CYAN, simply increase the HUE value (angle) slightly. 
    In RGB color space, the same task is less intuitive to achieve by increasing blue.
  <p>
    Differences become clear in Transitions however.
    In order to dim BLUE up the HSV Transitions 240,100,0 -> 240,100,100 would be used. 
    To slowly dim RED (brightness 0) to BLUE the Transition in the HSV color space is 0,100,0 -> 240,100,100.
    In RGB color space (# 000000 -> # 0000FF) can not distinguish between the two versions.
    Here (correctly, but probably differently than intended) would appear in both cases, a white (brightness 0) as an initial value.

  <p><b>Meaning of Flags</b></p>
  Certain commands (set) can be marked with special flags.
  <p>
  <ul>
    <li>ramp: 
      <ul>
        Time in seconds for a soft color or brightness transition. The soft transition starts at the currently visible color and is calculated for the specified.
      </ul>
    </li>
    <li>s: 
      <ul>
        (short, default). A smooth transition to another color is carried out in the <a href="#WifiLight_Farbkreis">"color wheel"</a> on the shortest path. 
        A transition from red to green lead by the shortest route through yellow.
      </ul>
    </li>
    <li>l: 
      <ul>
        (long). A smooth transition to another color is carried out in the <a href="#WifiLight_Farbkreis">"color wheel"</a> on the "long" way.
        A transition from red to green then leads across magenta, blue, and cyan.
      </ul>
    </li>
    <li>q: 
      <ul>
        (queue). Commands with this flag are cached in an internal queue and will not run before the currently running soft transitions have been processed. 
        Commands without the flag will be processed immediately. In this case all running transitions are stopped immediately and the queue will be cleared.
      </ul>
    </li>
    <li>event: 
      <ul>
        designator ([A-Za-z_0-9])
        <p>
          WifiLight creates, when using this flag, during transitions to another color messages (events) in the form:
        <p>
        <code>WifiLight &ltNAME&gt programm: &ltEVENT&gt &ltXX&gt</code>.
        <p>
        &ltEVENT&gt is the designator as specified in the flag.<br/>
        &ltXX&gt is the progress (percentage) of the transition.<br/>
        <p>
        Depending on the total duration of the transition, the values from 0 to 100 will not completely go through but for 0% and 100% is guaranteed always a event. 
        To these events can then be reacted within a notify or DOIF to (for example):
        <ul>
          <li>increase the volume of a radio when a lamp is turned on in the morning slowly</li>
          <li>A color transition can be restarted in a notify if it is complete (loop it, even complex transitions)</li>
          <li>Other light sources can be synchronized by individually created color transitions.</li>
        </ul>
      </ul>
    </li>
  </ul>
  <p><b><a name="WifiLight_Farbkalibrierung"></a>color calibration</b></p>
  WifiLight supports two different types of color calibrations:
  <ul>
    <p>
    <b>Correction of saturated colors</b>
    <p>
    background:
    <p>
      YELLOW, for example, is defined as a mixture of red and green light in equal parts.
      Depending on the LED and control used the green channel may be much more luminous.
      If the red and green LEDs are each fully driven, GREEN predominates in this mixture and the desired YELLOW would get a distinct green tint.
      In this example, no yellow would be generated (corresponding to 60 ° in the <a href="#WifiLight_Farbkreis">"color wheel"</a>) for HSV 60,100,100. 
      Instead GREEN would be generated with yellow tinge, perhaps corresponding to an estimated color angle of 80 °. 
      The required correction for yellow would therefore minus 20° (60° target - 80° result = -20° correction). 
      YELLOW may have to be corrected as to -20 °. Possible values per correction point are +/- 29 °.
    <p>
    procedure:
    <p>
      The correction of the full color is controlled by the attribute "color cast". 
      Here 6 (comma separated) values are specified in the range from -29 to 29. 
      These values are in accordance with the angle correction for red (0 °), yellow (60 °), green (120 °), cyan (180 °), blue (240 °) and magenta (300 °). 
      First, the deviation of the mixed colors (60 ° / 180 ° / 300 °) should be determined as in the above example, and stored in the attribute. 
      Following the primary colors (0 ° / 120 ° / 240 °) should be corrected so that the smooth transitions between adjacent pure colors appear as linear as possible. 
      This process may need to be repeated iteratively multiple times until the result is harmonious.
    <p>
    <b>White Balance</b>
    <p>
    background:
    <p>
    Some bulbs produce white light by mixing the RGB channels (for example, LW12). 
    Depending on the light intensity of the RGB channels of the LED strips used, the result is different. 
    One or two colors dominate. 
    In addition, there are various types of white light. 
    Cold light has a higher proportion of blue. 
    In Central Europe mostly warm white light is used for light sources. 
    This has a high red and low blue component.
    <p>
    WifiLight offers the possibility for mixed RGB white to adapt the composition. 
    The adjustment is carried out via the attribute "white point". 
    The attribute expects a value between 0 and 1 (decimal point with) and the three colors are separated by a comma for each of the three RGB channels.
    <p>
    procedure:
    <p>
    A value of "1,1,1" sets all the three channels to 100% each. 
    Assuming that the blue component of the white light should be reduced, a value of "1,1,0.5" sets the third channel (BLUE) in white on 0.5 according to 50%. 
    Before doing a white balance correction the adjusment of the saturated color should be completed.
  </ul>
  <p><b>Attribute</b></p>
  <ul>
    <li>
      <code>attr &ltname&gt <b>colorCast</b> &ltR,Y,G,C,B,M&gt</code>
      <p>   
      <a href="#WifiLight_Farbkalibrierung">color calibration</a> of saturated colors.
      R(ed), Y(ellow), G(reen), C(yan), B(lue), M(agenta) in the range of +/- 29 (degrees)
    </li>
    <li>
      <code>attr &ltname&gt <b>defaultColor</b> &ltH,S,V&gt</code>
      <p>   
      Specify the light color in HSV which is selected at "on". Default is white.
    </li>
    <li>
      <code>attr &ltname&gt <b>defaultRamp</b> &lt0 bis X&gt</code>
      <p>   
      Time in seconds. If this attribute is set, a smooth transition is always implicitly generated if no ramp in the set is indicated.
    </li>
    <li>
      <code>attr &ltname&gt <b>dimStep</b> &lt0 bis 100&gt</code>
      <p>   
      Value by which the brightness at dim up and dim-down is changed. Default is "7"
    </li>
    <li>
      <code>attr &ltname&gt <b>gamma</b> &ltX.X&gt</code>
      <p>   
        The human eye perceives brightness changes very differently to (logarithmic). 
        At low output brightness even a small change in brightness is perceived as very strong and on the other side strong changes are needed at high luminance. 
        Therefore, a logarithmic correction of brightness increase of lamps is necessary so that the increase is found to be uniform. 
        Some controllers perform this correction internally. 
        In other cases it is necessary to store this correction in the module. 
        A gamma value of 1.0 (default) results in a linear output values. 
        Values less than 1.0 lead to a logarithmic correction.
    </li>

  <p><b>Farbangaben: HSV gegenüber RGB</b><p>
        <p>
        Im Normalfall kann eine Farbe im HSV Farbraum genauso wie im RGB Farbraum dargestellt werden.
        <p>
        Farben im HSV Farbraum wirken meist verständlicher. 
        Um ein Grün im HSV Farbraum etwas mehr in Richtung CYAN zu bewegen wird einfach der HUE Wert (Winkel) etwas erhöht. 
        Im RGB Farbraum ist die gleiche Aufgabe weniger intuitiv durch eine Erhöhung von BLAU zu erreichen. 
        <p>
        Unterschiede werden jedoch bei Transitions deutlich. 
        Um BLAU langsam auf zu dimmen lauten die HSV Transitions 240,100,0 -> 240,100,100. 
        Um von ROT (Helligkeit 0) langsam auf BLAU zu dimmen wird im HSV Farbraum 0,100,0 -> 240,100,100 verwendet. 
        Im RGB Farbraum (#000000 -> #0000FF) kann nicht zwischen den beiden Varianten unterschieden werden. 
        Hier würde (richtiger weise, vermutlich jedoch anders als beabsichtigt) in beiden Fällen ein Weiß (Helligkeit 0) als Startwert erscheinen.

  <p><b>Bedeutung der Flags</b></p>
  Bestimmte Befehle (set) können mit speziellen Flags versehen werden.
  <p>
  <ul>
    <li>ramp: 
      <ul>
        Zeit in Sekunden für einen weichen Farb- oder Helligkeitsübergang. Der weiche Übergang startet bei der aktuell sichtbaren Farbe und wird zur angegeben berechnet. 
      </ul>
    </li>
    <li>s: 
      <ul>
        (short, default). Ein weicher Übergang zu einer anderen Farbe wird im <a href="#WifiLight_Farbkreis">"Farbkreis"</a> auf dem kürzesten Weg durchgeführt.</br>
        Eine Transition von ROT nach GRÜN führt auf dem kürzesten Weg über GELB.
      </ul>
    </li>
    <li>l: 
      <ul>
        (long). Ein weicher Übergang zu einer anderen Farbe wird im <a href="#WifiLight_Farbkreis">"Farbkreis"</a> auf dem "langen" Weg durchgeführt.</br>
        Eine Transition von ROT nach GRÜN führt dann über MAGENTA, BLAU, und CYAN.
      </ul>
    </li>
    <li>q: 
      <ul>
        (queue). Kommandos mit diesem Flag werden in einer internen Warteschlange zwischengespeichert und erst ausgeführt nachdem die aktuell laufenden weichen Übergänge
        abgearbeitet wurden. Kommandos ohne das Flag werden sofort abgearbeitet. Dabei werden alle laufenden Übergänge sofort abgebrochen und die Warteschlange wird gelöscht.
      </ul>
    </li>
    <li>event: 
      <ul>
        Beliebige Bezeichnung ([A-Za-z_0-9])
        <p>
        WifiLight erzeugt bei Verwendung dieses Flags im Verlauf weicher Übergange zu einer anderen Farbe Nachrichten (events) in der Form:
        <p>
        <code>WifiLight &ltNAME&gt programm: &ltEVENT&gt &ltXX&gt</code>.
        <p>
        &ltEVENT&gt entspricht dem Namen so wie im Flag angegeben.<br/>
        &ltXX&gt ist der prozentuale Fortschritt des Übergangs.<br/>
        <p>
        Je nach Gesamtdauer des Übergangs werden die Werte von 0 bis 100 nicht komplett durchlaufen wobei jedoch für 0% und 100% immer ein event garantiert ist. Auf diese events kann dann innerhalb von notify oder DOIF reagiert werden um zum Beispiel:
        <ul>
          <li>die Lautstärke eines Radios anzupassen wenn eine LED morgens langsam hochgedimmt wird</li>
          <li>ein Farbübergang kann in einem notify neu gestartet werden wenn er komplett ist (loop)</li>
          <li>andere Leuchtmittel können mit erstellten Farbübergängen synchronisiert werden</li>
        </ul>
      </ul>
    </li>
  </ul>
  <p><b><a name="WifiLight_Farbkalibrierung"></a>Farbkalibrierung</b></p>
  WifiLight unterstützt zwei unterschiedliche Formen der Farbkalibrierungen:
  <ul>
    <p>
    <b>Korrektur gesättigter Farben</b>
    <p>
    Hintergrund:
    <p>
    GELB, zum Beispiel, ist definiert als Mischung aus ROTEM und GRÜNEM Licht zu gleichen Teilen. 
    Je nach verwendeter LED und Ansteuerung ist der GRÜNE Kanal nun möglicherweise viel leuchtstärker.
    Wenn jetzt also die ROTE und GRÜNE LED jeweils voll angesteuert werden überwiegt GRÜN in dieser Mischung und das gewünschte GELB bekäme einen deutlichen Grünstich.
    In diesem Beispiel würde jetzt für HSV 60,100,100 kein Gelb (entsprechend 60° im <a href="#WifiLight_Farbkreis">"Farbkreis"</a>) erzeugt. 
    Stattdessen würde GRÜN mit GELBSTICH erzeugt das vielleicht einem geschätzten Farbwinkel von 80° entspricht.
    Die erforderliche Korrektur für GELB würde also minus 20° betragen (60° SOLL - 80° IST = -20° Korrektur). 
    GELB müsste als um -20° korrigiert werden. Mögliche Werte pro Korrektur-Punkt sind +/- 29°.
    <p>
    Vorgehen:
    <p>
    Die Korrektur der Vollfarben wird über das Attribut "colorCast" gesteuert. Dabei werden 6 (Komma getrennte) Werte im Bereich -29 bis 29 angegeben.
    Diese Werte stehen entsprechen der Winkelkorrektur für ROT (0°), GELB (60°), GRÜN (120°), CYAN (180°), BLAU (240°) und MAGENTA (300°).
    Zuerst sollte die Abweichung für 60°/180°/300° (die Mischfarben) so wie in obigem Beispiel ermittelt und im Attribut hinterlegt werden.
    Im Anschluss sollten die Primärfarben (0°/120°/240°) so korrigiert werden das die weichen Übergänge zwischen benachbarten reinen Farben möglichst linear erscheinen.
    Dieser Vorgang muss eventuell iterativ mehrfach wiederholt werden bis das Ergebniss stimmig ist. 
    <p>
    <b>Weißabgleich</b>
    <p>
    Hintergrund:
    <p>
    Einige Leuchtmittel erzeugen weißes Licht durch Mischung der RGB Kanäle (zum Beispiel LW12). 
    Je nach Leuchtstärke der RGB Kanäle der verwendeten LED Streifen unterscheidet sich das Ergebnis und eine oder zwei Farben dominieren. 
    Zusätzlich gibt es verschiedene Formen weißen Lichtes. Kaltes Licht hat einen höheren Blauanteil. 
    Dagegen wird in Mitteleuropa für Leuchtmittel meist warm-weiß verwendet welches einen hohen ROT- und geringen BLAU Anteil hat.
    <p>
    WifiLight bietet die Möglichkeit bei RGB gemischtem Weiß die Zusammensetzung anzupassen. Die Anpassung erfolgt über das Attribut "whitePoint".
    Dieses erwartet für jeden der drei RGB Kanäle einen Wert zwischen 0 und 1 (ein Komma wird als Punkt angegeben). Die drei Werte werden mit einem normalen Komma getrennt.
    <p>
    Vorgehen:
    <p>
    Eine Angabe von "1,1,1" setzt alle die drei Kanäle auf jeweils 100%. Angenommen der BLAU Anteil des weißen Lichtes soll nun verringert werden. 
    Ein Wert von "1,1,0.5" setzt den dritten Kanal (BLAU) bei Weiß auf 0.5 entsprechend 50%. Vor einem Weißabgleich sollte die Korrektur der Vollfarben abgeschlossen sein.  
  </ul>
  <p><b>Attribute</b></p>
  <ul>
    <li>
      <code>attr &ltname&gt <b>colorCast</b> &ltR,Y,G,C,B,M&gt</code>
      <p>   
      <a href="#WifiLight_Farbkalibrierung">Farbkalibrierung</a> der voll gesättigten Farben.
      R(ed), Y(ellow), G(reen), C(yan), B(lue), M(agenta) im Bereich +/- 29
    </li>
    <li>
      <code>attr &ltname&gt <b>defaultColor</b> &ltH,S,V&gt</code>
      <p>   
      HSV Angabe der Lichtfarbe die bei "on" gewählt wird. Default ist Weiß.
    </li>
    <li>
      <code>attr &ltname&gt <b>defaultRamp</b> &lt0 bis X&gt</code>
      <p>   
      Zeit in Sekunden. Wenn dieses Attribut gesetzt ist wird implizit immer ein weicher Übergang erzeugt wenn keine Ramp im set angegeben ist. 
    </li>
    <li>
      <code>attr &ltname&gt <b>dimStep</b> &lt0 bis 100&gt</code>
      <p>   
      Wert um den die Helligkeit bei dimUp und dimDown verändert wird. Default 7.
    </li>
    <li>
      <code>attr &ltname&gt <b>gamma</b> &ltX.X&gt</code>
      <p>   
      Das menschliche Auge nimmt Helligkeitsänderungen sehr unterschiedlich wahr (logarithmisch). 
      Bei geringer Ausgangshelligkeit wird schon eine kleine Helligkeitsänderung als sehr stark empfunden und auf der anderen Seite sind bei großer Helligkeit starke Änderungen notwendig.
      Daher ist eine logarithmische Korrektur des Helligkeitsanstiegs der Leuchtmittel erforderlich damit der Anstieg als gleichmäßig empfunden wird.
      Einige controller führen diese Korrektur intern durch. In anderen Fällen ist es notwendig diese Korrektur im Modul zu hinterlegen.
      Ein gamma Wert von 1.0 (default) führt zu einer linearen Ausgabe der Werte. Werte kleiner als 1.0 führen zu einer logarithmischem Korrektur.
