#
# FHEM module to commmunicate with a Sonos-System via UPnP
#
########################################################################################
# !ATTENTION!
# This Module needs additional Perl-Libraries.
# Install:
#  * LWP::Simple
#  * LWP::UserAgent
#  * HTTP::Request
#  * SOAP::Lite
# 
# e.g. as Debian-Packages (via "sudo apt-get install <packagename>")
#  * LWP::Simple-Packagename (incl. LWP::UserAgent and HTTP::Request): libwww-perl
#  * SOAP::Lite-Packagename: libsoap-lite-perl
#
# e.g. as Windows ActivePerl (via Perl-Packagemanager)
#  * Install Package LWP (incl. LWP::UserAgent and HTTP::Request)
#  * Install Package SOAP::Lite
#  * SOAP::Lite-Special for Versions after 5.18:
#    * Add another Packagesource from suggestions or manual: Bribes de Perl (http://www.bribes.org/perl/ppm)
#      * Install Package: SOAP::Lite
#
# Windows ActivePerl 5.20 does currently not work due to missing SOAP::Lite
#
########################################################################################
# Configuration:
# define <name> SONOS [<host:port> [interval [waittime [delaytime]]]]
#
# where <name> may be replaced by any fhem-devicename string 
# <host:port> is the connection identifier to the internal server. Normally "localhost" with a locally free port e.g. "localhost:4711".
# interval is the interval in s, for checking the existence of a ZonePlayer
# waittime is the time to wait for the subprocess. defaults to 8.
# delaytime is the time for delaying the network- and subprocess-part of this module. If the port is longer than neccessary blocked on the subprocess-side, it may be useful.
#
##############################################
# Example:
# Simplest way to define:
# define Sonos SONOS
#
# Example with control over the used port and the isalive-checker-interval:
# define Sonos SONOS localhost:4711 45

# Changelog (last 4 entries only, see Wiki for complete changelog)
#
# SVN-History:
# 10.03.2018
#	Die PlayBase kann nun auch den SPDIF-Eingang aktivieren (wie die PlayBar)
#	Wenn man über Alexa Musik hört, wird das aktuelle Cover nun auch angezeigt.
#	Wenn ein Player nach einem Neustart disabled war, und während des Betriebs enabled wird, wird nun versucht ihn wiederzufinden.
#	Wenn ein Player disabled oder disappeared ist, wird ein Proxy-Cover-Zugriffsversuch auf diesen Player unterbunden.
#	Ein Modify-Befehlsaufruf wird nun am Vorhandensein von $hash->{OLDDEF} erkannt.
#	Bei einigen PERL-Installationen stand im Reading 'currentTrackPositionSimulatedSec' eine Kommazahl (da sie von time() aus berechnet wird). Diese Zahl wird nun gerundet.
# 26.02.2018
#	ComObjectTransportQueue in Client_ReceiveQueue umbenannt.
#	If-Abfrage um die can_read-Schleife im SubProzess eingebaut, Um Signalunterbrechungen zu berücksichtigen.
#	Neuer Getter "WifiPortStatus". Liefert Active, wenn das WLAN aktiviert ist, sonst Inactive.
#	Drei neue (automatisch ermittelte) Readings "Orientation", "WifiEnabled" und "WirelessMode".
#	Warnung mit "unescaped left brace" in Tag.pm wurde korrigiert.
#	ExportSonosBibliothek wird nun in einem eigenen Thread (LongJobs-Thread) ausgeführt. Dadurch bleibt das System steuerbar, auch wenn gerade ein langwieriger Export läuft.
#	Prüfmethode eingebaut, um verlorengegangene Fhem-Prozessverbindungen (aus Sicht des SubProzesses) zu erkennen, und entsprechende Thread-Bereinigungmaßnahmen durchführen zu können.
# 07.01.2018
#	Der Initialwert von LastProcessAnswer (wird beim Start auf 0 gesetzt) wird nun korrekt berücksichtigt
#	Bei ignoredIPs und bei usedOnlyIPs kann jetzt für jedes Komma-Getrennte Element auch ein regulärer Ausdruck stehen. Wird mit // umschlossen, und darf keine Doppelpunkte enthalten.
#	Logausgabe im UPnP-Modul, welche Devices mit welchen Header-Angaben nun akzeptiert wurden (Ausgabe auf Level 5)
# 23.12.2017
#	Subscriptions-Refresh umgebaut.
#	Devicenamen mit Punkt (.) funktionieren nun.
#	Fehler mit "undefined value $value" behoben.
#	GetTrackProvider liefert bei Nichtfinden in der MusicServicesList nun eine leere Angabe, und keine undefined.
#	Die Angabe in LastProcessAnswer ist nicht Zeitumstellungsfest. Der Wert wurde nun umgestellt auf epoch-Zeit.
#	Der Verweis auf %intAt wurde entfernt. Die Variable wurde sowieso nie verwendet.
#	Warnungsunterdrückung von 'mumpitzstuff' eingebaut.

=item summary_DE Modul für die Kommunikation mit einem Sonos-System mittels UPnP
=begin html

<a name="SONOS"></a>
<h3>SONOS</h3>
<p>FHEM-Module to communicate with the Sonos-System via UPnP</p>
<p>For more informations have also a closer look at the wiki at <a href="http://www.fhemwiki.de/wiki/SONOS">http://www.fhemwiki.de/wiki/SONOS</a></p>
<p>For correct functioning of this module it is neccessary to have some Perl-Modules installed, which are eventually installed already manually:<ul>
<li><code>LWP::Simple</code></li>
<li><code>LWP::UserAgent</code></li>
<li><code>SOAP::Lite</code></li>
<li><code>HTTP::Request</code></li></ul>
Installation e.g. as Debian-Packages (via "sudo apt-get install &lt;packagename&gt;"):<ul>
<li>LWP::Simple-Packagename (incl. LWP::UserAgent and HTTP::Request): libwww-perl</li>
<li>SOAP::Lite-Packagename: libsoap-lite-perl</li></ul>
<br />Installation e.g. as Windows ActivePerl (via Perl-Packagemanager)<ul>
<li>Install Package LWP (incl. LWP::UserAgent and HTTP::Request)</li>
<li>Install Package SOAP::Lite</li>
<li>SOAP::Lite-Special for Versions after 5.18:<ul>
  <li>Add another Packagesource from suggestions or manual: Bribes de Perl (http://www.bribes.org/perl/ppm)</li>
  <li>Install Package: SOAP::Lite</li></ul></li></ul>
<b>Windows ActivePerl 5.20 does currently not work due to missing SOAP::Lite</b></p>
<p><b>Attention!</b><br />This Module will not work on any platform, because of the use of Threads and the neccessary Perl-modules.</p>
<p>More information is given in a (german) Wiki-article: <a href="http://www.fhemwiki.de/wiki/SONOS">http://www.fhemwiki.de/wiki/SONOS</a></p>
<p>The system consists of two different components:<br />
1. A UPnP-Client which runs as a standalone process in the background and takes the communications to the sonos-components.<br />
2. The FHEM-module itself which connects to the UPnP-client to make fhem able to work with sonos.<br /><br />
The client will be started by the module itself if not done in another way.<br />
You can start this client on your own (to let it run instantly and independent from FHEM):<br />
<code>perl 00_SONOS.pm 4711</code>: Starts a UPnP-Client in an independant way who listens to connections on port 4711. This process can run a long time, FHEM can connect and disconnect to it.</p>
<h4>Example</h4>
<p>
Simplest way to define:<br />
<b><code>define Sonos SONOS</code></b>
</p>
<p>
Example with control over the used port and the isalive-checker-interval:<br />
<b><code>define Sonos SONOS localhost:4711 45</code></b>
</p>
<a name="SONOSdefine"></a>
<h4>Define</h4>
<b><code>define &lt;name&gt; SONOS [upnplistener [interval [waittime [delaytime]]]]</code></b>
        <br /><br /> Define a Sonos interface to communicate with a Sonos-System.<br />
<p>
<b><code>[upnplistener]</code></b><br />The name and port of the external upnp-listener. If not given, defaults to <code>localhost:4711</code>. The port has to be a free portnumber on your system. If you don't start a server on your own, the script does itself.<br />If you start it yourself write down the correct informations to connect.</p>
<p>
<b><code>[interval]</code></b><br /> The interval is for alive-checking of Zoneplayer-device, because no message come if the host disappear :-)<br />If omitted a value of 10 seconds is the default.</p>
<p>
<b><code>[waittime]</code></b><br /> With this value you can configure the waiting time for the starting of the Subprocess.</p>
<p>
<b><code>[delaytime]</code></b><br /> With this value you can configure a delay time before starting the network-part.</p>
<a name="SONOSset"></a>

In this example there are two groups: the first consists of one player and the second consists of two players.<br />
The order in the sublists are important, because the first entry defines the so-called group-coordinator (in this case <code>Sonos_Wohnzimmer</code>), from which the current playlist and the current title playing transferred to the other member(s).</li>
</ul></li>
</ul>
<a name="SONOSattr"></a>
<h4>Attributes</h4>
'''Attention'''<br />The most of the attributes can only be used after a restart of fhem, because it must be initially transfered to the subprocess.
<ul>
<li><b>Common</b><ul>

</a><br /> Defines the style of the Device in the room overview. <code>Both</code> means "normal" Deviceline incl. Cover-/Titleview and maybe the control area, <code>DeviceLineOnly</code> means only the "normal" Deviceline-view.</li>
<li><a name="SONOS_attribut_disable"><b><code>disable &lt;value&gt;</code></b>
</a><br />One of (0,1). With this value you can disable the whole module. Works immediatly. If set to 1 the subprocess will be terminated and no message will be transmitted. If set to 0 the subprocess is again started.<br />It is useful when you install new Sonos-Components and don't want any disgusting devices during the Sonos setup.</li>
<li><a name="SONOS_attribut_getFavouritesListAtNewVersion"><b><code>getFavouritesListAtNewVersion &lt;value&gt;</code></b>
</a><br />One of (0,1). With this attribute set, the module will refresh the Favourites-List automatically upon changes (if the Attribute <code>getListsDirectlyToReadings</code> is set).</li>
<li><a name="SONOS_attribut_getPlaylistsListAtNewVersion"><b><code>getPlaylistsListAtNewVersion &lt;value&gt;</code></b>
</a><br />One of (0,1). With this attribute set, the module will refresh the Playlists-List automatically upon changes (if the Attribute <code>getListsDirectlyToReadings</code> is set).</li>
<li><a name="SONOS_attribut_getQueueListAtNewVersion"><b><code>getQueueListAtNewVersion &lt;value&gt;</code></b>
</a><br />One of (0,1). With this attribute set, the module will refresh the current Queue-List automatically upon changes (if the Attribute <code>getListsDirectlyToReadings</code> is set).</li>

</a><br />One of (0,1). With this attribute set, the module will refresh the Radios-List automatically upon changes (if the Attribute <code>getListsDirectlyToReadings</code> is set).</li>
<li><a name="SONOS_attribut_getListsDirectlyToReadings"><b><code>getListsDirectlyToReadings &lt;value&gt;</code></b>
</a><br />One of (0,1). With this attribute you can define that the module fills the readings for the lists of Favourites, Playlists, Radios and the Queue directly without the need of userReadings.</li>
<li><a name="SONOS_attribut_getLocalCoverArt"><b><code>getLocalCoverArt &lt;value&gt;</code></b>
</a><br />One of (0,1). With this attribute the loads and saves the Coverart locally (default till now).</li>
<li><a name="SONOS_attribut_ignoredIPs"><b><code>ignoredIPs &lt;IP-Address&gt;[,IP-Address]</code></b>
</a><br />With this attribute you can define IP-addresses, which has to be ignored by the UPnP-System of this module. e.g. "192.168.0.11,192.168.0.37"</li>
<li><a name="SONOS_attribut_pingType"><b><code>pingType &lt;string&gt;</code></b>
</a><br /> One of (none,tcp,udp,icmp,syn). Defines which pingType for alive-Checking has to be used. If set to 'none' no checks will be done.</li>
<li><a name="SONOS_attribut_reusePort"><b><code>reusePort &lt;int&gt;</code></b>

<li><a name="SONOS_attribut_SubProcessLogfileName"><b><code>SubProcessLogfileName &lt;Path&gt;</code></b>
</a><br /> If given, the subprocess logs into its own logfile. Under Windows this is a recommended way for logging, because the two Loggings (Fehm and the SubProcess) overwrite each other. If "-" is given, the logging goes to STDOUT (and therefor in the Fhem-log) as usual. The main purpose of this attribute is the short-use of separated logging. No variables are substituted. The value is used as configured.</li>
<li><a name="SONOS_attribut_usedonlyIPs"><b><code>usedonlyIPs &lt;IP-Adresse&gt;[,IP-Adresse]</code></b>
</a><br />With this attribute you can define IP-addresses, which has to be exclusively used by the UPnP-System of this module. e.g. "192.168.0.11,192.168.0.37"</li>

</ul></li>
<li><b>Proxy Configuration</b><ul>
<li><a name="SONOS_attribut_generateProxyAlbumArtURLs"><b><code>generateProxyAlbumArtURLs &lt;int&gt;</code></b>
</a><br />One of (0, 1). If defined, all Cover-Links (the readings "currentAlbumArtURL" and "nextAlbumArtURL") are generated as links to the internal Sonos-Module-Proxy. It can be useful if you access Fhem over an external proxy and therefore have no access to the local network (the URLs are direct URLs to the Sonosplayer instead).</li>
<li><a name="SONOS_attribut_proxyCacheDir"><b><code>proxyCacheDir &lt;Path&gt;</code></b>
</a><br />Defines a directory where the cached Coverfiles can be placed. If not defined "/tmp" will be used.</li>

<h3>SONOS</h3>
<p>FHEM-Modul für die Anbindung des Sonos-Systems via UPnP</p>
<p>Für weitere Hinweise und Beschreibungen bitte auch im Wiki unter <a href="http://www.fhemwiki.de/wiki/SONOS">http://www.fhemwiki.de/wiki/SONOS</a> nachschauen.</p>
<p>Für die Verwendung sind Perlmodule notwendig, die unter Umständen noch nachinstalliert werden müssen:<ul>
<li><code>LWP::Simple</code></li>
<li><code>LWP::UserAgent</code></li>
<li><code>SOAP::Lite</code></li>
<li><code>HTTP::Request</code></li></ul>
Installation z.B. als Debian-Pakete (mittels "sudo apt-get install &lt;packagename&gt;"):<ul>
<li>LWP::Simple-Packagename (inkl. LWP::UserAgent und HTTP::Request): libwww-perl</li>
<li>SOAP::Lite-Packagename: libsoap-lite-perl</li></ul>
<br />Installation z.B. als Windows ActivePerl (mittels Perl-Packagemanager)<ul>
<li>Package LWP (incl. LWP::UserAgent and HTTP::Request)</li>
<li>Package SOAP::Lite</li>
<li>SOAP::Lite-Special für Versionen nach 5.18:<ul>
  <li>Eine andere Paketquelle von den Vorschlägen oder manuell hinzufügen: Bribes de Perl (http://www.bribes.org/perl/ppm)</li>
  <li>Package: SOAP::Lite</li></ul></li></ul>
<b>Windows ActivePerl 5.20 kann momentan nicht verwendet werden, da es das Paket SOAP::Lite dort momentan nicht gibt.</b></p>
<p><b>Achtung!</b><br />Das Modul wird nicht auf jeder Plattform lauffähig sein, da Threads und die angegebenen Perl-Module verwendet werden.</p>
<p>Mehr Informationen im (deutschen) Wiki-Artikel: <a href="http://www.fhemwiki.de/wiki/SONOS">http://www.fhemwiki.de/wiki/SONOS</a></p>
<p>Das System besteht aus zwei Komponenten:<br />
1. Einem UPnP-Client, der als eigener Prozess im Hintergrund ständig läuft, und die Kommunikation mit den Sonos-Geräten übernimmt.<br />
2. Dem eigentlichen FHEM-Modul, welches mit dem UPnP-Client zusammenarbeitet, um die Funktionalität in FHEM zu ermöglichen.<br /><br />
Der Client wird im Notfall automatisch von Modul selbst gestartet.<br />
Man kann den Server unabhängig von FHEM selbst starten (um ihn dauerhaft und unabh&auml;ngig von FHEM laufen zu lassen):<br />
<code>perl 00_SONOS.pm 4711</code>: Startet einen unabhängigen Server, der auf Port 4711 auf eingehende FHEM-Verbindungen lauscht. Dieser Prozess kann dauerhaft laufen, FHEM kann sich verbinden und auch wieder trennen.</p>
<h4>Beispiel</h4>
<p>
Einfachste Definition:<br />
<b><code>define Sonos SONOS</code></b>
</p>
<p>
Definition mit Kontrolle über den verwendeten Port und das Intervall der IsAlive-Prüfung:<br />
<b><code>define Sonos SONOS localhost:4711 45</code></b>
</p>
<a name="SONOSdefine"></a>
<h4>Definition</h4>
<b><code>define &lt;name&gt; SONOS [upnplistener [interval [waittime [delaytime]]]]</code></b>
        <br /><br /> Definiert das Sonos interface für die Kommunikation mit dem Sonos-System.<br />
<p>
<b><code>[upnplistener]</code></b><br />Name und Port eines externen UPnP-Client. Wenn nicht angegebenen wird <code>localhost:4711</code> festgelegt. Der Port muss eine freie Portnummer ihres Systems sein. <br />Wenn sie keinen externen Client gestartet haben, startet das Skript einen eigenen.<br />Wenn sie einen eigenen Dienst gestartet haben, dann geben sie hier die entsprechenden Informationen an.</p>
<p>
<b><code>[interval]</code></b><br /> Das Interval wird für die Überprüfung eines Zoneplayers benötigt. In diesem Interval wird nachgeschaut, ob der Player noch erreichbar ist, da sich ein Player nicht mehr abmeldet, wenn er abgeschaltet wird :-)<br />Wenn nicht angegeben, wird ein Wert von 10 Sekunden angenommen.</p>
<p>
<b><code>[waittime]</code></b><br /> Hiermit wird die Wartezeit eingestellt, die nach dem Starten des SubProzesses darauf gewartet wird.</p>
<p>
<b><code>[delaytime]</code></b><br /> Hiermit kann eine Verzögerung eingestellt werden, die vor dem Starten des Netzwerks gewartet wird.</p>

<li><b>Gruppenbefehle</b><ul>
<li><a name="SONOS_setter_Groups">
<b><code>Groups &lt;GroupDefinition&gt;</code></b></a>
<br />Setzt die aktuelle Gruppierungskonfiguration der Sonos-Systemlandschaft. Das Format ist jenes, welches auch von dem Get-Befehl 'Groups' geliefert wird.<br >Hier kann als GroupDefinition das Wort <i>Reset</i> verwendet werden, um alle Player aus ihren Gruppen zu entfernen.</li>

<h4>Get</h4>
<ul>
<li><b>Gruppenbefehle</b><ul>
<li><a name="SONOS_getter_Groups">
<b><code>Groups</code></b></a>
<br />Liefert die aktuelle Gruppierungskonfiguration der Sonos Systemlandschaft zurück. Das Format ist eine Kommagetrennte Liste von Listen mit Devicenamen, also z.B. <code>[Sonos_Kueche], [Sonos_Wohnzimmer, Sonos_Schlafzimmer]</code>. In diesem Beispiel sind also zwei Gruppen definiert, von denen die erste aus einem Player und die zweite aus Zwei Playern besteht.<br />
Dabei ist die Reihenfolge innerhalb der Unterlisten wichtig, da der erste Eintrag der sogenannte Gruppenkoordinator ist (in diesem Fall also <code>Sonos_Wohnzimmer</code>), von dem die aktuelle Abspielliste un der aktuelle Titel auf die anderen Gruppenmitglieder übernommen wird.</li>
</ul></li>

<a name="SONOSattr"></a>
<h4>Attribute</h4>
'''Hinweis'''<br />Die Attribute werden erst bei einem Neustart von Fhem verwendet, da diese dem SubProzess initial zur Verfügung gestellt werden müssen.
<ul>
<li><b>Grundsätzliches</b><ul>
<li><a name="SONOS_attribut_coverLoadTimeout"><b><code>coverLoadTimeout &lt;value&gt;</code></b>
</a><br />Eines von (0..10,15,20,25,30). Definiert den Timeout der für die Abfrage des Covers beim Sonosplayer verwendet wird. Wenn nicht angegeben, dann wird 5 verwendet.</li>
<li><a name="SONOS_attribut_deviceRoomView"><b><code>deviceRoomView &lt;Both|DeviceLineOnly&gt;</code></b>
</a><br /> Gibt an, was in der Raumansicht zum Sonosplayer-Device angezeigt werden soll. <code>Both</code> bedeutet "normale" Devicezeile zzgl. Cover-/Titelanzeige und u.U. Steuerbereich, <code>DeviceLineOnly</code> bedeutet nur die Anzeige der "normalen" Devicezeile.</li>
<li><a name="SONOS_attribut_disable"><b><code>disable &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Hiermit kann das Modul abgeschaltet werden. Wirkt sofort. Bei 1 wird der SubProzess beendet, und somit keine weitere Verarbeitung durchgeführt. Bei 0 wird der Prozess wieder gestartet.<br />Damit kann das Modul temporär abgeschaltet werden, um bei der Neueinrichtung von Sonos-Komponenten keine halben Zustände mitzubekommen.</li>
<li><a name="SONOS_attribut_getFavouritesListAtNewVersion"><b><code>getFavouritesListAtNewVersion &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Mit diesem Attribut kann das Modul aufgefordert werden, die Favoriten (bei definiertem Attribut <code>getListsDirectlyToReadings</code>) bei Aktualisierung automatisch herunterzuladen.</li>
<li><a name="SONOS_attribut_getPlaylistsListAtNewVersion"><b><code>getPlaylistsListAtNewVersion &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Mit diesem Attribut kann das Modul aufgefordert werden, die Playlisten (bei definiertem Attribut <code>getListsDirectlyToReadings</code>) bei Aktualisierung automatisch herunterzuladen.</li>
<li><a name="SONOS_attribut_getQueueListAtNewVersion"><b><code>getQueueListAtNewVersion &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Mit diesem Attribut kann das Modul aufgefordert werden, die aktuelle Abspielliste (bei definiertem Attribut <code>getListsDirectlyToReadings</code>) bei Aktualisierung automatisch herunterzuladen.</li>
<li><a name="SONOS_attribut_getRadiosListAtNewVersion"><b><code>getRadiosListAtNewVersion &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Mit diesem Attribut kann das Modul aufgefordert werden, die Radioliste (bei definiertem Attribut <code>getListsDirectlyToReadings</code>) bei Aktualisierung automatisch herunterzuladen.</li>
<li><a name="SONOS_attribut_getListsDirectlyToReadings"><b><code>getListsDirectlyToReadings &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Mit diesem Attribut kann das Modul aufgefordert werden, die Listen für Favoriten, Playlists, Radios und Queue direkt in die entsprechenden Readings zu schreiben. Dafür sind dann keine Userreadings mehr notwendig.</li>
<li><a name="SONOS_attribut_getLocalCoverArt"><b><code>getLocalCoverArt &lt;value&gt;</code></b>
</a><br />Eines von (0,1). Mit diesem Attribut kann das Modul aufgefordert werden, die Cover lokal herunterzuladen (bisheriges Standardverhalten).</li>
<li><a name="SONOS_attribut_ignoredIPs"><b><code>ignoredIPs &lt;IP-Adresse&gt;[,IP-Adresse]</code></b>
</a><br />Mit diesem Attribut können IP-Adressen angegeben werden, die vom UPnP-System ignoriert werden sollen. Z.B.: "192.168.0.11,192.168.0.37"</li>
<li><a name="SONOS_attribut_pingType"><b><code>pingType &lt;string&gt;</code></b>
</a><br /> Eines von (none,tcp,udp,icmp,syn). Gibt an, welche Methode für die Ping-Überprüfung verwendet werden soll. Wenn 'none' angegeben wird, dann wird keine Überprüfung gestartet.</li>
<li><a name="SONOS_attribut_reusePort"><b><code>reusePort &lt;int&gt;</code></b>
</a><br /> Eines von (0,1). Gibt an, ob die Portwiederwendung für SSDP aktiviert werden soll, oder nicht. Kann Restart-Probleme lösen. Wenn man diese Probleme nicht hat, sollte man das Attribut nicht setzen.</li>
<li><a name="SONOS_attribut_SubProcessLogfileName"><b><code>SubProcessLogfileName &lt;Pfad&gt;</code></b>
</a><br /> Hiermit kann für den SubProzess eine eigene Logdatei angegeben werden. Unter Windows z.B. überschreiben sich die beiden Logausgaben (von Fhem und SubProzess) sonst gegenseitig. Wenn "-" angegeben wird, wird wie bisher auf STDOUT (und damit im Fhem-Log) geloggt. Der Hauptanwendungsfall ist die mehr oder weniger kurzfristige Fehlersuche. Es werden keinerlei Variablenwerte ersetzt, und der Wert direkt als Dateiname verwendet.</li>
<li><a name="SONOS_attribut_usedonlyIPs"><b><code>usedonlyIPs &lt;IP-Adresse&gt;[,IP-Adresse]</code></b>
</a><br />Mit diesem Attribut können IP-Adressen angegeben werden, die ausschließlich vom UPnP-System berücksichtigt werden sollen. Z.B.: "192.168.0.11,192.168.0.37"</li>
</ul></li>
<li><b>Bookmark-Einstellungen</b><ul>
<li><a name="SONOS_attribut_bookmarkSaveDir"><b><code>bookmarkSaveDir &lt;path&gt;</code></b>
</a><br /> Das Verzeichnis, in dem die Dateien für die gespeicherten Bookmarks abgelegt werden sollen. Wenn nicht festgelegt, dann wird "." verwendet.</li>
<li><a name="SONOS_attribut_bookmarkTitleDefinition"><b><code>bookmarkTitleDefinition &lt;Groupname&gt;:&lt;PlayerdeviceRegEx&gt;:&lt;TrackURIRegEx&gt;:&lt;MinTitleLength&gt;:&lt;RemainingLength&gt;:&lt;MaxAge&gt;:&lt;ReadOnly&gt; [...]</code></b>
</a><br /> Die Definition für die Verwendung von Bookmarks für Titel.</li>
<li><a name="SONOS_attribut_bookmarkPlaylistDefinition"><b><code>bookmarkPlaylistDefinition &lt;Groupname&gt;:&lt;PlayerdeviceRegEx&gt;:&lt;MinListLength&gt;:&lt;MaxListLength&gt;:&lt;MaxAge&gt; [...]</code></b>
</a><br /> Die Definition für die Verwendung von Bookmarks für aktuelle Abspiellisten/Playlisten.</li>
</ul></li>
<li><b>Proxy-Einstellungen</b><ul>
<li><a name="SONOS_attribut_generateProxyAlbumArtURLs"><b><code>generateProxyAlbumArtURLs &lt;int&gt;</code></b>
</a><br /> Aus (0, 1). Wenn aktiviert, werden alle Cober-Links als Proxy-Aufrufe an Fhem generiert. Dieser Proxy-Server wird vom Sonos-Modul bereitgestellt. In der Grundeinstellung erfolgt kein Caching der Cover, sondern nur eine Durchreichung der Cover von den Sonosplayern (Damit ist der Zugriff durch einen externen Proxyserver auf Fhem möglich).</li>
<li><a name="SONOS_attribut_proxyCacheDir"><b><code>proxyCacheDir &lt;Path&gt;</code></b>
</a><br /> Hiermit wird das Verzeichnis festgelegt, in dem die Cober zwischengespeichert werden. Wenn nicht festegelegt, so wird "/tmp" verwendet.</li>
<li><a name="SONOS_attribut_proxyCacheTime"><b><code>proxyCacheTime &lt;int&gt;</code></b>
</a><br /> Mit einer Angabe ungleich 0 wird der Caching-Mechanismus des Sonos-Modul-Proxy-Servers aktiviert. Dabei werden Cover, die im Cache älter sind als diese Zeitangabe in Sekunden, neu vom Sonosplayer geladen, alle anderen direkt ausgeliefert, ohne den Player zu fragen.</li>
<li><a name="SONOS_attribut_webname"><b><code>webname &lt;String&gt;</code></b>
</a><br /> Hiermit kann der zu verwendende Webname für die Cover-Link-Erzeugung angegeben werden. Da vom Modul Links zu Cover u.ä. erzeugt werden, ohne dass es einen FhemWeb-Aufruf dazu gibt, kann das Modul diesen Pfad nicht selber herausfinden. Wenn das Attribut nicht angegeben wird, dann wird 'fhem' angenommen.</li>
</ul></li>
<li><b>Sprachoptionen</b><ul>
<li><a name="SONOS_attribut_targetSpeakDir"><b><code>targetSpeakDir &lt;string&gt;</code></b>
</a><br /> Gibt an, welches Verzeichnis für die Ablage des MP3-Files der Textausgabe verwendet werden soll</li>
<li><a name="SONOS_attribut_targetSpeakMP3FileConverter"><b><code>targetSpeakMP3FileConverter &lt;string&gt;</code></b>
</a><br /> Hiermit kann ein MP3-Konverter angegeben werden, da am Ende der Verkettung der Speak-Ansage das resultierende MP3-File nochmal sauber durchkodiert. Damit können Restzeitanzeigeprobleme behoben werden. Dadurch vegrößert sich allerdings u.U. die Ansageverzögerung.</li>
<li><a name="SONOS_attribut_targetSpeakMP3FileDir"><b><code>targetSpeakMP3FileDir &lt;string&gt;</code></b>
</a><br /> Das Verzeichnis, welches als Standard für MP3-Fileangaben in Speak-Texten verwendet werden soll. Wird dieses Attribut definiert, können die Angaben bei Speak ohne Verzeichnis erfolgen.</li>
<li><a name="SONOS_attribut_targetSpeakURL"><b><code>targetSpeakURL &lt;string&gt;</code></b>
</a><br /> Gibt an, unter welcher Adresse der ZonePlayer das unter targetSpeakDir angegebene Verzeichnis erreichen kann.</li>
<li><a name="SONOS_attribut_targetSpeakFileTimestamp"><b><code>targetSpeakFileTimestamp &lt;int&gt;</code></b>
</a><br /> One of (0, 1). Gibt an, ob die erzeugte MP3-Sprachausgabedatei einen Zeitstempel erhalten soll (1) oder nicht (0).</li>
<li><a name="SONOS_attribut_targetSpeakFileHashCache"><b><code>targetSpeakFileHashCache &lt;int&gt;</code></b>
</a><br /> One of (0, 1). Gibt an, ob die erzeugte Sprachausgabedatei einen Hashwert erhalten soll (1) oder nicht (0). Wenn dieser Wert gesetzt wird, dann wird eine bereits bestehende Datei wiederverwendet, und nicht neu erzeugt.</li>
<li><a name="SONOS_attribut_Speak1"><b><code>Speak1 &lt;Fileextension&gt;:&lt;Commandline&gt;</code></b>
</a><br />Hiermit kann ein Systemaufruf definiert werden, der zu Erzeugung einer Sprachausgabe verwendet werden kann. Sobald dieses Attribut definiert wurde, ist ein entsprechender Setter am Sonosplayer verfügbar.<br />Es dürfen folgende Platzhalter verwendet werden:<br />'''%language%''': Wird durch die eingegebene Sprache ersetzt<br />'''%filename%''': Wird durch den kompletten Dateinamen (inkl. Dateiendung) ersetzt.<br />'''%text%''': Wird durch den zu übersetzenden Text ersetzt.<br />'''%textescaped%''': Wird durch den URL-Enkodierten zu übersetzenden Text ersetzt.</li>
<li><a name="SONOS_attribut_Speak2"><b><code>Speak2 &lt;Fileextension&gt;:&lt;Commandline&gt;</code></b>
</a><br />Siehe Speak1</li>
<li><a name="SONOS_attribut_Speak3"><b><code>Speak3 &lt;Fileextension&gt;:&lt;Commandline&gt;</code></b>
</a><br />Siehe Speak1</li>
<li><a name="SONOS_attribut_Speak4"><b><code>Speak4 &lt;Fileextension&gt;:&lt;Commandline&gt;</code></b>
</a><br />Siehe Speak1</li>
<li><a name="SONOS_attribut_SpeakCover"><b><code>SpeakCover &lt;Absolute-Imagepath&gt;</code></b>
</a><br />Hiermit kann ein JPG- oder PNG-Bild als Cover für die Sprachdurchsagen definiert werden.</li>
<li><a name="SONOS_attribut_Speak1Cover"><b><code>Speak1Cover &lt;Absolute-Imagepath&gt;</code></b>
</a><br />Analog zu SpeakCover für Speak1.</li>
<li><a name="SONOS_attribut_Speak2Cover"><b><code>Speak2Cover &lt;Absolute-Imagepath&gt;</code></b>
</a><br />Analog zu SpeakCover für Speak2.</li>
<li><a name="SONOS_attribut_Speak3Cover"><b><code>Speak3Cover &lt;Absolute-Imagepath&gt;</code></b>
</a><br />Analog zu SpeakCover für Speak3.</li>
<li><a name="SONOS_attribut_Speak3Cover"><b><code>Speak3Cover &lt;Absolute-Imagepath&gt;</code></b>
</a><br />Analog zu SpeakCover für Speak3.</li>
<li><a name="SONOS_attribut_Speak4Cover"><b><code>Speak4Cover &lt;Absolute-Imagepath&gt;</code></b>
</a><br />Analog zu SpeakCover für Speak4.</li>
<li><a name="SONOS_attribut_SpeakGoogleURL"><b><code>SpeakGoogleURL &lt;GoogleURL&gt;</code></b>
</a><br />Die zu verwendende Google-URL. Wenn dieser Parameter nicht angegeben wird, dann wird ein Standard verwendet. Hier müssen Platzhalter für die Ersetzung durch das Modul eingetragen werden: %1$s -> Sprache, %2$s -> Text<br />Die Standard-URL lautet momentan: <code>http://translate.google.com/translate_tts?tl=%1$s&client=tw-ob&q=%2$s</code></li>
