<h3>PRESENCE</h3>
<ul>
  <tr><td>
  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>lan-bluetooth</b> - A presence check of a bluetooth device via LAN network by connecting to a presenced or collectord instance</li>
  </ul>
  <br><br>
  <a name="PRESENCEdefine"></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>
    <b>Mode: fritzbox</b><br><br>
    <code>define &lt;name&gt; PRESENCE fritzbox &lt;device-name&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<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>
    <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 &lt;ip-address&gt;[:port] &lt;bluetooth-address&gt; [ &lt;check-interval&gt; ]</code><br>
    <br>
    The default port is 5111 (presenced). Alternatly you can use port 5222 (collectord)<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>
<PRE>
Usage:
  presenced -d [-p &lt;port&gt;] [-P &lt;filename&gt;]

    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>
    
    The presenced is available as:<br><br>

    Before the collectord can be used, it needs a config file, where all different rooms, which have a presenced detector, will be listed. This config file looks like:
    <br><br>
<PRE>
       	# room definition
       	# ===============
	#
	[room-name]              # name of the room

	port=5111                # tcp port which should be used (5111 is default)
	presence_timeout=120     # timeout in seconds for each check when devices are present
	absence_timeout=20       # timeout in seconds for each check when devices are absent

	[living room]
	address=192.168.0.11
	port=5111	
	presence_timeout=180
	absence_timeout=20

    If a device is present in any of the configured rooms, this is send to FHEM, as well as the device name as reading and the room which has detected the device.<br><br>

<h3>PRESENCE</h3>
<ul>
  <tr><td>
  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>lan-bluetooth</b> - Eine Erkennung durch Bluetooth-Abfragen via Netzwerk (LAN/WLAN) in ein oder mehreren R&auml;umen</li>
  </ul>
  <br><br>
  <a name="PRESENCEdefine"></a>

  <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>
    <b>Modus: fritzbox</b><br><br>
    <code>define &lt;name&gt; PRESENCE fritzbox &lt;device-name&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;device-name&gt;) muss dem Namen entsprechen, welcher im Men&uuml;punkt "Heimnetz" auf der FritzBox-Oberfl&auml;che angezeigt wird.<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>
    <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 &lt;IP-Adresse&gt;[:Port] &lt;Bluetooth-Adresse&gt; [ &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>presenced</u><br><br>
    <ul>Der presenced ist ein Perl Netzwerk Dienst, 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>

    Zur Bluetooth-Abfrage wird der Shell-Befehl "hcitool" verwendet (Paket: <a href="http://www.bluez.org" target="_new">bluez</a>) 
    um sogenannte "Paging-Request" an die gew&uuml;nschte Bluetooth Adresse (z.B. 01:B4:5E:AD:F6:D3) durchzuf&uuml;hren. Das Ger&auml;t muss dabei nicht sichtbar sein, allerdings st&auml;ndig aktiviert sein
    um Bluetooth-Anfragen zu beantworten.
    <br><br>
    
    Wenn ein Ger&auml;t anwesend ist, wird dies an FHEM &uuml;bermittelt zusammen mit dem Ger&auml;tenamen als Reading.<br><br>
