#
#     Fhem Perl module for controlling the Yamaha PianoCraft(TM) HiFi
#     Network Audiosystem MCR-N560(D) over Ethernet.
#     The system is also marketed as CRX-N560(D).
#
#     The module might also work with other devices such as
#     NP-S2000, CD-N500, CD-N301, R-N500, R-N301 or any other device
#     implementing the Yamaha Network Player Controller(TM) protocol:
#
#     i*S:
#     https://itunes.apple.com/us/app/network-player-controller-us/id467502483?mt=8
#
#     Andr*id:
#     https://play.google.com/store/apps/details?id=com.yamaha.npcontroller
#
#     Since the used communication protocol is undisclosed the module bases on
#     entirely reverse engineered implementation.
#     Some features may be unavailable.
#     (Online check for new firmware was excluded intentionally.)

      define &lt;name&gt; YAMAHA_NP &lt;ip-address&gt; [&lt;status_interval&gt;]<br><br>

    This module controls a Yamaha Network Player (such as MCR-N560, MCR-N560D, CRX-N560, CRX-N560D, CD-N500 or NP-S2000) via Ethernet.
    Theoretically, any device understanding the communication protocol of the Yamaha Network Player App should work. 
    <br><br>
    Currently implemented features:
    <br><br>
    <ul>
      <li>Power on/off</li>
      <li>Timer on/off</li>
      <li>Input selection</li>
      <li>Timer on/off</li>
      <li>Volume +/-</li>
      <li>Mute on/off</li>
      <li>System Clock Update</li>
      <li>Tuner: tune +/-, preset +/-, Station information (FM/DAB)</li>
      <li>Stand-by mode: eco/normal</li>
      <li>Player (play, stop, next, prev, shuffle, repeat)</li>
      <li>Menu navigation</li>
      <li>...</li>
    </ul>
    <br>
    Defining a YAMAHA_NP device will schedule an internal task (interval can be set
    with optional parameters &lt;off_status_interval&gt; and &lt;on_status_interval&gt; in seconds.<br>
    &lt;off_status_interval&gt; is a parameter used in case the device is powered off or not available.<br>
    &lt;on_status_interval&gt; is a parameter used in case the device is powered on.<br>
    If both parameters are unset, a default value 30 (seconds) for both is used.<br>
    If &lt;off_status_interval&gt; is set only the same value is used for both parameters.
    <br>
    The internal task periodically reads the status of the Network Player (power state, selected
    input, volume and mute status etc.) and triggers notify/filelog commands.
    <br><br>    
    Example:<br><br>
    <ul><br>
      Add the following code into the <b>fhem.cfg</b> configuration file and restart fhem:<br><br>
      <code>
      define NP_Player YAMAHA_NP 192.168.0.15<br>
      attr NP_player webCmd input:volume:mute:volumeDown:volumeUp<br><br>

    </ul><br><br>
    A typical example is powering the device remotely and tuning the favourite radio station:<br><br>
    Add the following code into the <b>fhem.cfg</b> configuration file:<br><br><br>
    <ul>
      <code>
        define NP_player YAMAHA_NP 192.168.0.15 30 5<br>
        attr NP_player webCmd input:volume:mute:volumeDown:volumeUp
      </code>
    </ul><br><br>
    Add the following code into the <b>99_MyUtils.pm</b> file:<br><br>
    <ul>
      <code>
        sub startMyFavouriteRadioStation()<br>
        {<br>
          &nbsp;&nbsp;fhem "set NP_player on";<br>
          &nbsp;&nbsp;sleep 1;<br>
          &nbsp;&nbsp;fhem "set NP_player input tuner";<br>
          &nbsp;&nbsp;sleep 1;<br>
          &nbsp;&nbsp;fhem "set NP_player tunerPresetDAB 1";<br>
          &nbsp;&nbsp;sleep 1;<br>
          &nbsp;&nbsp;fhem "set NP_player volume 30";<br>
        }
      </code>
    </ul>
    <br><br>
    It's a good idea to insert a 'sleep' instruction between each fhem commands due to internal processing time of the network player. During that time the following commands might be ignored...<br><br>
    Now the function can be called by typing the following line in the FHEM command line or by the notify-definitions:<br><br>
    <ul>
      <code>
        {startMyFavouriteRadioStation()}<br><br>
      </code>
    </ul>
  </ul>

  <b>Get</b>
  <ul>
    <code>
      get &lt;name&gt; &lt;reading&gt;
    </code>
    <br><br>

  <b>Implementer's note</b><br><br>
    <ul>
    Trivial: In order to use that module the network player must be connected to the Ethernet.<br>
    The device must be in standbyMode "Normal" in order to power on.<br>
    However, even if the standbyMode is set to "Eco" the device can be powered off. In that case it has to be switched on manually.<br>

    Mit Hilfe dieses Moduls lassen sich Yamaha Network Player (z.B. MCR-N560, MCR-N560D, CRX-N560, CRX-N560D, CD-N500 or NP-S2000) via Ethernet steuern.<br>
    Theoretisch sollten alle Ger&auml;te, die mit der Yamaha Network Player App kompatibel sind, bedient werden k&ouml;nnen.<br><br>
    Die aktuelle Implementierung erm&ouml;glicht u.a. den folgenden Funktionsumfang:<br><br>
    <ul>
      <li>Power on/off</li>
      <li>Timer on/off</li>

    Eine YAMAHA_NP Definition initiiert einen internen Task, der von FHEM zyklisch abgearbeitet wird.<br>
    Das Intervall (in Sekunden) kann f&uuml;r die Zust&auml;nde &lt;on_status_interval&gt; und &lt;off_status_interval&gt; optional gesetzt werden.<br>
    &lt;off_status_interval&gt; steht f&uuml;r das Intervall, wenn das Ger&auml;t ausgeschaltet/abwesend ist.<br>
    &lt;on_status_interval&gt; steht f&uuml;r das Intervall, wenn das Ger&auml;t eingeschaltet/verf&uuml;gbar ist.<br>
    Wenn keine Parametere angegeben wurden, wird ein Default-Wert von 30 Sekunden f&uuml;r beide gesetzt.<br>
    Wenn nur &lt;off_status_interval&gt; gesetzt wird, gilt dieser Wert f&uuml;r beide Zust&auml;nde (eingeschaltet/ausgeschaltet).<br>
    Der Task liest zyklisch grundlegende Parameter vom Network Player wie z.B. (Power-Status , gew&auml;hlter Eingang, Lautst&auml;rke etc.) und triggert notify/filelog Befehle.<br><br>

      Ein typisches Beispiel ist das Einschalten des Ger&auml;tes und das Umschalten auf den Lieblingsradiosender:<br><br>
      Beispieldefinition in der <b>fhem.cfg</b> Konfigurationsdatei:<br><br><br>
      <ul>
        <code>

          attr NP_player webCmd input:volume:mute:volumeDown:volumeUp
        </code>
      </ul><br><br>
      Folgender Code kann anschlie&szlig;end in die Datei <b>99_MyUtils.pm</b> eingebunden werden:<br><br>
      <ul>
        <code>
          sub startMyFavouriteRadioStation()<br>

            &nbsp;&nbsp;fhem "set NP_player on";<br>

      <i>Bemerkung: Aufgrund der relativ langsamen Befehlsverarbeitung im Network Player im Vergleich zur asynchronen Ethernet-Kommunikation, kann es vorkommen, dass veraltete Statusinformationen zur&uuml;ckgesendet werden.<br>
      Aus diesem Grund wird empfohlen, w&auml;hrend der Automatisierung zwischen den 'set' und 'get' Befehlen ein Delay einzubauen. Speziell beim Hochfahren des Network Players sollte dies beachtet werden.</i><br><br>

    Das Ger&auml;t muss sich im standbyMode "Normal" befinden, um es fergesteuert einzuschalten.<br>
