<h3>PRESENCE</h3>
<ul>
The PRESENCE module provides several possibilities to check the presence of mobile phones or similar mobile devices such as tablets.
<br><br>
This module provides several operational modes to serve your needs. These are:<br><br>
<ul>
<li><b>lan-ping</b> - A presence check of a device via network ping in your LAN/WLAN.</li>
<li><b>fritzbox</b> - A presence check by requesting the device state from the FritzBox internals (only available when running FHEM on a FritzBox!).</li>
<li><b>local-bluetooth</b> - A presence check by searching directly for a given bluetooth device nearby.</li>
<li><b>function</b> - A presence check by using your own perl function which returns a presence state.</li>
<li><b>shellscript</b> - A presence check by using an self-written script or binary which returns a presence state.</li>
<li><b>event</b> - A presence check by listening to FHEM events of other definitions.</li>
<li><b>lan-bluetooth</b> - A presence check of a bluetooth device via LAN network by connecting to a presenced or collectord instance.</li>
</ul>
<br>
Each mode can be optionally configured with a specific check interval and a present check interval.<br><br>
<ul>
<li>check-interval - The interval in seconds between each presence check. Default value: 30 seconds</li>
<li>present-check-interval - The interval in seconds between each presence check in case the device is <i>present</i>. Otherwise the normal check-interval will be used.</li>
</ul>
<br><br>
<a name="PRESENCE_define"></a>
<b>Define</b><br><br>
<ul><b>Mode: lan-ping</b><br><br>
<code>define &lt;name&gt; PRESENCE lan-ping &lt;ip-address&gt; [ &lt;check-interval&gt; [ &lt;present-check-interval&gt; ] ]</code><br>
<br>
Checks for a network device via PING requests and reports its presence state.<br><br>
<u>Example</u><br><br>
<code>define iPhone PRESENCE lan-ping 192.168.179.21</code><br>
<br>
<b>Mode: fritzbox</b><br><br>
<code>define &lt;name&gt; PRESENCE fritzbox &lt;device-name/mac-address&gt; [ &lt;check-interval&gt; [ &lt;present-check-interval&gt; ] ]</code><br>
<br>
Checks for a network device by requesting the internal state on a FritzBox via ctlmgr_ctl. The device-name must be the same as shown in the network overview of the FritzBox or can be substituted by the MAC address with the format XX:XX:XX:XX:XX:XX<br><br>
<i>This check is only applicable when FHEM is running on a FritzBox! The detection of absence can take about 10-15 minutes!</i><br><br>
<u>Example</u><br><br>
<code>define iPhone PRESENCE fritzbox iPhone-6</code><br>
<code>define iPhone PRESENCE fritzbox 00:06:08:05:0D:00</code><br><br>
<b>Mode: local-bluetooth</b><br><br>
<code>define &lt;name&gt; PRESENCE local-bluetooth &lt;bluetooth-address&gt; [ &lt;check-interval&gt; [ &lt;present-check-interval&gt; ] ]</code><br>
<br>
Checks for a bluetooth device and reports its presence state. For this mode the shell command "hcitool" is required (provided with a <a href="http://www.bluez.org" target="_new">bluez</a> installation under Debian via APT), as well
as a functional bluetooth device directly attached to your machine.<br><br>
<u>Example</u><br><br>
<code>define iPhone PRESENCE local-bluetooth 0a:8d:4f:51:3c:8f</code><br><br>
<b>Mode: function</b><br><br>
<code>define &lt;name&gt; PRESENCE function {...} [ &lt;check-interval&gt; [ &lt;present-check-interval&gt; ] ]</code><br>
<br>
Checks for a presence state via perl-code. You can use a self-written perl function to obtain the presence state of a specific device (e.g. via SNMP check).<br><br>
The function must return 0 (absent) or 1 (present). An example can be found in the <a href="http://www.fhemwiki.de/wiki/Anwesenheitserkennung" target="_new">FHEM-Wiki</a>.<br><br>
<u>Example</u><br><br>
<code>define iPhone PRESENCE function {snmpCheck("10.0.1.1","0x44d77429f35c")}</code><br><br>
<b>Mode: shellscript</b><br><br>
<code>define &lt;name&gt; PRESENCE shellscript "&lt;path&gt; [&lt;arg1&gt;] [&lt;argN&gt;]..." [ &lt;check-interval&gt; [ &lt;present-check-interval&gt; ] ]</code><br>
<br>
Checks for a presence state via shell script. You can use a self-written script or binary in any language to obtain the presence state of a specific device (e.g. via SNMP check).<br><br>
The shell must return 0 (absent) or 1 (present) on <u>console (STDOUT)</u>. Any other values will be treated as an error<br><br>
<u>Example</u><br><br>
<code>define iPhone PRESENCE shellscript "/opt/check_device.sh iPhone"</code><br><br>
<b>Mode: event</b><br><br>
<code>define &lt;name&gt; PRESENCE event &lt;absent-regexp&gt; &lt;present-regexp&gt;</code><br>
<br>
Listens for events of other FHEM definitions to determine a presence state. You must provide two event regexp's in the same style as for the <a href="#notify">notify</a> module.<br><br>
If an event matches one of the provides regexps, the presence state will be changed.<br><br>
<u>Example</u><br><br>
<code>define Presence_John PRESENCE event Door_Switch:off Door_Switch:on</code><br><br>
<b>Mode: lan-bluetooth</b><br><br>
Checks for a bluetooth device with the help of presenced or collectord. They can be installed where-ever you like, just must be accessible via network.
The given device will be checked for presence status.<br>
<br>
<code>define &lt;name&gt; PRESENCE lan-bluetooth &lt;bluetooth-address&gt; &lt;ip-address&gt;[:port] [ &lt;check-interval&gt; ]</code><br>
<br>
The default port is 5111 (presenced). Alternatly you can use port 5222 (collectord)<br>
<br>
<u>Example</u><br><br>
<code>define iPhone PRESENCE lan-bluetooth 0a:4f:36:d8:f9:89 127.0.0.1:5222</code><br><br>
<u>presenced</u><br><br>
<ul>The presence is a perl network daemon, which provides presence checks of multiple bluetooth devices over network.
It listens on TCP port 5111 for incoming connections from a FHEM PRESENCE instance or a running collectord.<br>

It uses the hcitool command (provided by a <a href="http://www.bluez.org" target="_new">bluez</a> installation)
to make a paging request to the given bluetooth address (like 01:B4:5E:AD:F6:D3). The devices must not be visible, but
still activated to receive bluetooth requests.<br><br>
If a device is present, this is send to FHEM, as well as the device name as reading.<br><br>

<u>lepresenced</u><br><br>
<ul>lepresenced is a Perl network daemon that provides presence checks of
multiple bluetooth devices over network. In contrast to presenced,
lepresenced covers <u>Bluetooth 4.0 (low energy) devices, i. e.
Gigaset G-Tags, FitBit Charges.</u>
lepresenced listens on TCP port 5333 for connections of a PRESENCE definition
or collectord.<br>
<PRE>
Usage:
lepresenced --bluetoothdevice &lt;bluetooth device&gt; --listenaddress &lt;listen address&gt; --listenport &lt;listen port&gt; --loglevel &lt;log level&gt; --daemon
lepresenced -b &lt;bluetooth device&gt; -a &lt;listen address&gt; -p &lt;listen port> -l &lt;log level&gt; -d
valid log levels:
LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG. Default: LOG_INFO
Examples:
lepresenced --bluetoothdevice hci0 --listenaddress 127.0.0.1 --listenport 5333 --daemon
lepresenced --loglevel LOG_DEBUG --daemon
</PRE>
To detect the presence of a device, it uses the command <i>hcitool lescan</i> (package:
<a href="http://www.bluez.org" target="_new">bluez</a>) to continuously listen to
beacons of Bluetooth LE devices.
<br><br>
If a device is present, this is send to FHEM, as well as the device name as reading.<br><br>

<h3>PRESENCE</h3>
<ul>
Das PRESENCE Module bietet mehrere M&ouml;glichkteiten um die Anwesenheit von Handys/Smartphones oder anderen mobilen Ger&auml;ten (z.B. Tablets) zu erkennen.
<br><br>
Dieses Modul bietet dazu mehrere Modis an um Anwesenheit zu erkennen. Diese sind:<br><br>
<ul>
<li><b>lan-ping</b> - Eine Erkennung auf Basis von Ping-Tests im lokalen LAN/WLAN</li>
<li><b>fritzbox</b> - Eine Erkennung aufgrund der internen Abfrage des Status auf der FritzBox (nur m&ouml;glich, wenn FHEM auf einer FritzBox l&auml;uft)</li>
<li><b>local-bluetooth</b> - Eine Erkennung auf Basis von Bluetooth-Abfragen durch den FHEM Server. Das Ger&auml;t muss dabei in Empfangsreichweite sein, aber nicht sichtbar sein</li>
<li><b>function</b> - Eine Erkennung mithilfe einer selbst geschriebenen Perl-Funktion, welche den Anwesenheitsstatus ermittelt.</li>
<li><b>shellscript</b> - Eine Erkennung mithilfe eines selbst geschriebenen Skriptes oder Programm (egal in welcher Sprache).</li>
<li><b>event</b> - Eine Erkennung basierend auf Events einer anderen Definition in FHEM. </li>
<li><b>lan-bluetooth</b> - Eine Erkennung durch Bluetooth-Abfragen via Netzwerk (LAN/WLAN) in ein oder mehreren R&auml;umen</li>
</ul>
<br>
Jeder Modus kann optional mit spezifischen Pr&uuml;f-Intervallen ausgef&uuml;hrt werden.<br><br>
<ul>
<li>check-interval - Das normale Pr&uuml;finterval in Sekunden f&uuml;r eine Anwesenheitspr&uuml;fung. Standardwert: 30 Sekunden</li>
<li>present-check-interval - Das Pr&uuml;finterval in Sekunden, wenn ein Ger&auml;t anwesend (<i>present</i>) ist. Falls nicht angegeben, wird der Wert aus check-interval verwendet</li>
</ul>
<br><br>
<a name="PRESENCE_define"></a>
<b>Define</b><br><br>
<ul><b>Modus: lan-ping</b><br><br>
<code>define &lt;name&gt; PRESENCE lan-ping &lt;IP-Addresse oder Hostname&gt; [ &lt;Interval&gt; [ &lt;Anwesend-Interval&gt; ] ]</code><br>
<br>
Pr&uuml;ft ob ein Ger&auml;t &uuml;ber Netzwerk (&uuml;blicherweise WLAN) auf Ping-Anfragen reagiert und setzt entsprechend den Anwesenheitsstatus.<br><br>
<u>Beispiel</u><br><br>
<code>define iPhone PRESENCE lan-ping 192.168.179.21</code><br><br>
<b>Modus: fritzbox</b><br><br>
<code>define &lt;name&gt; PRESENCE fritzbox &lt;Ger&auml;tename/MAC-Adresse&gt; [ &lt;Interval&gt; [ &lt;Anwesend-Interval&gt; ] ]</code><br>
<br>
Pr&uuml;ft ob ein Ger&auml;t welches per WLAN mit der FritzBox verbunden ist, erreichbar durch Abfrage des Status mit dem Befehl ctlmgr_ctl.
Der Ger&auml;tename (Parameter: &lt;Ger&auml;tename&gt;) muss dem Namen entsprechen, welcher im Men&uuml;punkt "Heimnetz" auf der FritzBox-Oberfl&auml;che angezeigt wird oder kann durch die MAC-Adresse im Format XX:XX:XX:XX:XX:XX ersetzt werden.<br><br>
<i>Dieser Modus ist nur verwendbar, wenn FHEM auf einer FritzBox l&auml;uft! Die Erkennung einer Abwesenheit kann ca. 10-15 Minuten dauern!</i><br><br>
<u>Beispiel</u><br><br>
<code>define iPhone PRESENCE fritzbox iPhone-6</code><br>
<code>define iPhone PRESENCE fritzbox 00:06:08:05:0D:00</code><br><br>
<b>Modus: local-bluetooth</b><br><br>
<code>define &lt;name&gt; PRESENCE local-bluetooth &lt;Bluetooth-Adresse&gt; [ &lt;Interval&gt; [ &lt;Anwesend-Interval&gt; ] ]</code><br>
<br>
Pr&uuml;ft ob ein Bluetooth-Ger&auml;t abgefragt werden kann und meldet dies als Anwesenheit. F&uuml;r diesen Modus wird der Shell-Befehl "hcitool" ben&ouml;tigt
(wird durch das Paket <a href="http://www.bluez.org" target="_new">bluez</a> bereitgestellt), sowie ein funktionierender Bluetooth-Empf&auml;nger (intern oder als USB-Stick)<br><br>
<u>Beispiel</u><br><br>
<code>define iPhone PRESENCE local-bluetooth 0a:4f:36:d8:f9:8</code><br><br>
<b>Modus: function</b><br><br>
<code>define &lt;name&gt; PRESENCE function {...} [ &lt;Interval&gt; [ &lt;Anwesend-Interval&gt; ] ]</code><br>
<br>
Pr&uuml;ft den Anwesenheitsstatus mithilfe einer selbst geschriebenen Perl-Funktion (z.B. SNMP Abfrage).<br><br>
Diese Funktion muss 0 (Abwesend) oder 1 (Anwesend) zur&uuml;ckgeben. Ein entsprechendes Beispiel findet man im <a href="http://www.fhemwiki.de/wiki/Anwesenheitserkennung" target="_new">FHEM-Wiki</a>.<br><br>
<u>Beispiel</u><br><br>
<code>define iPhone PRESENCE function {snmpCheck("10.0.1.1","0x44d77429f35c")</code><br><br>
<b>Mode: shellscript</b><br><br>
<code>define &lt;name&gt; PRESENCE shellscript "&lt;Skript-Pfad&gt; [&lt;arg1&gt;] [&lt;argN&gt;]..." [ &lt;Interval&gt; [ &lt;Anwesend-Interval&gt; ] ]</code><br>
<br>
Pr&uuml;ft den Anwesenheitsstatus mithilfe eines selbst geschrieben Skripts oder Programmes (egal in welcher Programmier-/Skriptsprache)<br><br>
Der Aufruf dieses Skriptes muss eine 0 (Abwesend) oder 1 (Anwesend) auf der <u>Kommandozeile (STDOUT)</u> ausgeben. Alle anderen Werte/Ausgaben werden als Fehler behandelt.<br><br>
<u>Beispiel</u><br><br>
<code>define iPhone PRESENCE shellscript "/opt/check_device.sh iPhone"</code><br><br>
<b>Mode: event</b><br><br>
<code>define &lt;name&gt; PRESENCE event &lt;Abwesend-Regexp&gt; &lt;Anwesend-Regexp&gt;</code><br>
<br>
Lauscht auf Events von anderen Definitionen innerhalb von FHEM um die Anwesenheit darzustellen.
Die regul&auml;ren Ausdr&uuml;cke f&uuml;r An- und Abwesenheit entsprechen dabei der Syntax von <a href="#notify">notify</a>.<br><br>
Sobald innerhalb von FHEM ein Event gefeuert wird, welches auf die Abwesend-Regexp bzw. Anwesend-Regexp passt, wird der Status entsprechend in PRESENCE gesetzt.<br><br>
<u>Beispiel</u><br><br>
<code>define Anwesenheit PRESENCE event Tuerschalter:off Tuerschalter:on</code><br><br>
<b>Modus: lan-bluetooth</b><br><br>
Pr&uuml;ft ein Bluetooth-Ger&auml;t auf Anwesenheit &uuml;ber Netzwerk mit Hilfe von presenced oder collectord. Diese k&ouml;nnen auf jeder Maschine installiert werden,
welche eine Standard-Perl-Umgebung bereitstellt und &uuml;ber Netzwerk erreichbar ist.
<br>
<br>
<code>define &lt;name&gt; PRESENCE lan-bluetooth &lt;Bluetooth-Adresse&gt; &lt;IP-Adresse&gt;[:Port] [ &lt;Interval&gt; ]</code><br>
<br>
Der Standardport ist 5111 (presenced). Alternativ kann man den Port 5222 (collectord) nutzen. Generell ist der Port aber frei w&auml;hlbar.<br><br>
<u>Beispiel</u><br><br>
<code>define iPhone PRESENCE lan-bluetooth 0a:4f:36:d8:f9:89 127.0.0.1:5222</code><br><br>
<u>presenced</u><br><br>
<ul>Der presenced ist ein Perl Netzwerkdienst, welcher eine Bluetooth-Anwesenheitserkennung von ein oder mehreren Ger&auml;ten &uuml;ber Netzwerk bereitstellt.
Dieser lauscht standardm&auml;&szlig;ig auf TCP Port 5111 nach eingehenden Verbindungen von dem PRESENCE Modul oder einem collectord.<br>

Wenn dieses Attribut aktiviert ist, wird die Anwesenheitserkennung nicht mehr durchgef&uuml;hrt.<br><br>
M&ouml;gliche Werte: 0 => Erkennung durchf&uuml;hren , 1 => Keine Erkennungen durchf&uuml;hren<br>
Standardwert ist 0 (Erkennung durchf&uuml;hren)<br><br>
<li><a name="PRESENCE_absenceThreshold">absenceThreshold</a></li> <i>(Nicht im Modus "event" anwendbar)</i><br>
Die Anzahl an Checks, welche in "absent" resultieren m&uuml;ssen, bevor der Status der PRESENCE-Definition auf "absent" wechselt.
Mit dieser Funktion kann man die Abwesenheit eines Ger&auml;tes verifizieren bevor der Status final auf "absent" ge&auml;ndert wird.
Wenn dieses Attribut auf einen Wert &gt;1 gesetzt ist, werden die Readings "state" und "presence" auf den Wert "maybe absent" gesetzt,
bis der Status final auf "absent" wechselt.<br><br>
Standardwert ist 1 (keine Abwesenheitsverifizierung)<br><br>
<li><a name="PRESENCE_presenceThreshold">presenceThreshold</a></li> <i>(Nicht im Modus "event" anwendbar)</i><br>
Die Anzahl an Checks, welche in "present" resultieren m&uuml;ssen, bevor der Status der PRESENCE-Definition auf "present" wechselt.
Mit dieser Funktion kann man die Anwesenheit eines Ger&auml;tes verifizieren bevor der Status final auf "present" ge&auml;ndert wird.
Wenn dieses Attribut auf einen Wert &gt;1 gesetzt ist, werden die Readings "state" und "presence" auf den Wert "maybe present" gesetzt,
bis der Status final auf "present" wechselt.<br><br>
Standardwert ist 1 (keine Anwesenheitsverifizierung)<br><br>
<li><a name="PRESENCE_absenceTimeout">absenceTimeout</a></li> <i>(Nur im Modus "event" anwendbar)</i><br>
Die Dauer, die nach einem "absent"-Event gewartet werden soll, bis der Status der PRESENCE-Definition tats&auml;chlich auf "absent" ge&auml;ndert werden soll.
Die Dauer kann dabei im Format HH:MM:SS angegeben werden, wobei Stunden und Minuten optional sind.
Wenn dieses Attribut auf einen g&uuml;ltigen Wert gesetzt ist, werden die Readings "state" und "presence" bei einem "absent"-Event zun&auml;chst auf den Wert "maybe absent" gesetzt.
Sobald das parametrisierte Zeitfenster um ist, wird der Status final auf "absent" gesetzt.<br><br>
Standardwert ist 0 Sekunden (keine Statusverz&ouml;gerung)<br><br>
<li><a name="PRESENCE_presenceTimeout">presenceTimeout</a></li> <i>(Nur im Modus "event" anwendbar)</i><br>
Die Dauer, die nach einem "present"-Event gewartet werden soll, bis der Status der PRESENCE-Definition tats&auml;chlich auf "present" ge&auml;ndert werden soll.
Die Dauer kann dabei im Format HH:MM:SS angegeben werden, wobei Stunden und Minuten optional sind.
Wenn dieses Attribut auf einen g&uuml;ltigen Wert gesetzt ist, werden die Readings "state" und "presence" bei einem "present"-Event zun&auml;chst auf den Wert "maybe present" gesetzt.
Sobald das parametrisierte Zeitfenster um ist, wird der Status final auf "present" gesetzt.<br><br>
Standardwert ist 0 Sekunden (keine Statusverz&ouml;gerung)<br><br>
<li><a name="PRESENCE_retryInterval">retryInterval</a></li> <i>(Nicht im Modus "event" oder "lan-bluetooth" anwendbar)</i><br>
Das Prüfinterval, welches im Falle eines vorzeitig abgebrochenen Checks genutzt wird, um eine Wiederholung auszuführen. Dazu wird im Falle eines abgebrochenen
Checks der nächste Check nach der übergebenen Dauer in Sekunden ausgeführt. Diese sollte geringer sein als das reguläre Prüfinterval.
<br><br>
Standardwert ist 10 Sekunden<br><br>
<li><a name="PRESENCE_retryCount">retryCount</a></li> <i>(Nicht im Modus "event" oder "lan-bluetooth" anwendbar)</i><br>
Die maximale Anzahl an Wiederholungen, sollte ein Check vorzeitig abgebrochen werden. Sobald ein Check vorzeitigabbricht, werden maximal die übergebene Anzahl an Wiederholung
innerhalb des in retryInterval konfigurierten Interval ausgeführt um in kürzerer Zeit ein valides Ergebnis zu erhalten.
<br><br>
Standardwert ist 3 Wiederholungen<br><br>
<li><a name="PRESENCE_pingCount">pingCount</a></li> (Nur im Modus "ping" anwendbar)<br>
Ver&auml;ndert die Anzahl der Ping-Pakete die gesendet werden sollen um die Anwesenheit zu erkennen.
Je nach Netzwerkstabilit&auml;t k&ouml;nnen erste Pakete verloren gehen oder blockiert werden.<br><br>
Standardwert ist 4 (Versuche)<br><br>
<li><a name="PRESENCE_bluetoothHciDevice">bluetoothHciDevice</a></li> (Nur im Modus "local-bluetooth" anwendbar)<br>
Sofern man mehrere Bluetooth-Empf&auml;nger verf&uuml;gbar hat, kann man mit diesem Attribut ein bestimmten Empf&auml;nger ausw&auml;hlen, welcher zur Erkennung verwendet werden soll (bspw. hci0, hci1, ...). Es muss dabei ein vorhandener HCI-Ger&auml;tename angegeben werden wie z.B. <code>hci0</code>.
<br><br>
<li><a name="PRESENCE_fritzboxCheckSpeed">fritzboxCheckSpeed</a></li> (Nur im Modus "fritzbox")<br>
Zus&auml;tzlich zum Status des Ger&auml;ts wird die aktuelle Verbindungsgeschwindigkeit ausgegeben<br>
Das macht nur bei WLAN Ger&auml;ten Sinn, die direkt mit der FritzBox verbunden sind. Bei abwesenden Ger&auml;ten wird als Geschwindigkeit 0 ausgegeben.
<br><br>
M&ouml;gliche Werte: 0 => Geschwindigkeit nicht pr&uuml;fen, 1 => Geschwindigkeit pr&uuml;fen<br>
Standardwert ist 0 (Keine Geschwindigkeitspr&uuml;fung)
<br><br>
<li><a name="PRESENCE_powerCmd">powerCmd</a></li><br>
Ein FHEM-Befehl, welcher das Ger&auml;t schalten kann.<br><br>
Wenn der power-Befehl ausgef&uuml;hrt wird (set-Befehl: power) werden folgende Platzhalter durch ihre entsprechenden Werte ersetzt:<br><br>
<ul>
<li><code>$NAME</code> - Name der PRESENCE-Definition</li>
<li><code>$ADDRESS</code> - Die &uuml;berwachte Addresse der PRESENCE Definition, wie sie im define-Befehl angegeben wurde.</li>
<li><code>$ARGUMENT</code> - Das Argument, was dem Set-Befehl "power" &uuml;bergeben wurde. (z.B. "on" oder "off")</li>
</ul>
<br>
Beispielhafte FHEM-Befehle:<br><br>
<ul>
<li><code>set PowerSwitch_1 on</code></li>
<li><code>set PowerSwitch_1 $ARGUMENT</code></li>
<li><code>"/opt/power_on.sh $ADDRESS"</code></li>
<li><code>{powerOn("$ADDRESS", "username", "password")}</code></li>
