<h3>autocreate</h3>
<ul>

  Automatically create not yet defined FHEM devices upon reception of a message
  generated by this device. Note: devices which are polled (like the EMEM/EMWZ
  accessed through the EM1010PC) will NOT be automatically created.

  <br>

  <a name="autocreatedefine"></a>
  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; autocreate</code><br>
    <br>
    <ul>
      By defining an instance, the global attribute <a href=
      "#autoload_undefined_devices">autoload_undefined_devices</a>
      is set, so that modules for unknnown devices are automatically loaded.
      The autocreate module intercepts the UNDEFINED event generated by each
      module, creates a device and optionally also FileLog and SVG
      entries.<br>
      <b>Note 1:</b> devices will be created with a unique name, which contains
      the type and a unique id for this type. When <a href="#rename">renaming
      </a> the device, the automatically created filelog and SVG devices
      will also be renamed.<br>
      <b>Note 2:</b> you can disable the automatic creation by setting the
      <a href="#disable">disable</a> attribute, in this case only the rename
      hook is active, and you can use the  <a href="#createlog">createlog</a>
      command to add FileLog and SVG to an already defined device.
      <b>Note 3:</b> It makes no sense to create more than one instance of this
      module.

    </ul>
    <br>

    Example:<PRE>
    define autocreate autocreate
    attr autocreate autosave
    attr autocreate device_room %TYPE
    attr autocreate filelog test2/log/%NAME-%Y.log
    attr autocreate weblink
    attr autocreate weblink_room Plots
    </PRE>

  <b>Attributes</b>
  <ul>
    <a name="autosave"></a>
    <li>autosave<br>
        After creating a device, automatically save the config file with the
        command <a href="#save">save</a> command. Default is 1 (i.e. on), set
        it to 0 to switch it off.<br>
        <b>Note</b>: this attribute is deprecated, use the global autosave
        attribute instead.
        </li><br>

    <a name="device_room"></a>
    <li>device_room<br>
        "Put" the newly created device in this room. The name can contain the
        wildcards %TYPE and %NAME, see the example above.</li><br>

    <a name="filelogattr"></a>
    <li>filelog<br>
        Create a filelog associated with the device. The filename can contain
        the wildcards %TYPE and %NAME, see the example above. The filelog will
        be "put" in the same room as the device.</li><br>

    <a name="weblinkattr"></a>
    <li>weblink<br>
        Create an SVG associated with the device/filelog.</li><br>

    <a name="weblink_room"></a>
    <li>weblink_room<br>
        "Put" the newly created SVG in this room. The name can contain the
        wildcards %TYPE and %NAME, see the example above.</li><br>

    <li><a href="#disable">disable</a></li>
      <br>

    <a name="ignoreTypes"></a>
    <li>ignoreTypes<br>
        This is a regexp, to ignore certain devices, e.g. the neighbours FHT.
        You can specify more than one, with usual regexp syntax, e.g.<br>
        attr autocreate ignoreTypes CUL_HOERMANN.*|FHT_1234|CUL_WS_7<br>
        The word "Types" is somehow misleading, as it actually checks the
        generated device name.
        </li><br>

    <a name="autocreateThreshold"></a>
    <li>autocreateThreshold<br>
        A list of &lt;type&gt;:&lt;count&gt;:&lt;interval&gt; triplets. A new
        device is only created if there have been at least <code>count</code>
        events of TYPE <code>type</code> in the last <code>interval</code>
        seconds.<br> <code>attr autocreateThreshold
        LaCrosse:2:30,EMT7110:2:60</code>
        </li>

  </ul>
  <br>

  <a name="createlog"></a>
  <b>createlog</b>
  <ul>
      Use this command to manually add a FileLog and an SVG to an existing
      device. 
      This command is part of the autocreate module.
  </ul>
  <br>

  <a name="usb"></a>
  <b>usb</b>
  <ul>
      Usage:
      <ul><code>
        usb scan<br>
        usb create<br>
      </code></ul>
      This command will scan the /dev directory for attached USB devices, and
      will try to identify them. With the argument scan you'll get back a list
      of FHEM commands to execute, with the argument create there will be no
      feedback, and the devices will be created instead.<br><br>

      Note that switching a CUL to HomeMatic mode is still has to be done
      manually.<br><br>

      On Linux it will also check with the lsusb command, if unflashed CULs are
      attached. If this is the case, it will call CULflash with the appropriate
      parameters (or display the CULflash command if scan is specified). The
      usb command will only flash one device per call.<br><br>

      This command is part of the autocreate module.

<h3>autocreate</h3>
<ul>

  Erzeugt f&uuml;r noch nicht definierte FHEM-Ger&auml;te automatisch die
  geignete Definition (define). Diese Definition wird aus einer Nachricht
  gewonnen, die von diesen neuen Ger&auml;ten empfangen wurde. Hinweis:
  Ger&auml;te, die mit Polling arbeiten (wie z.B. der Zugriff auf EMEM/EMWZ
  &uuml;ber EM1010PC) werden NICHT automatisch erzeugt.
  <br><br>

  <a name="autocreatedefine"></a>
  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; autocreate</code><br>
    <br>
    <ul>
      Durch die Definition dieser Instanz wird das globale Attribut <a
      href="#autoload_undefined_devices">autoload_undefined_devices</a>
      gesetzt, sodass die Module f&uuml;r unbekannte Ger&auml;te automatisch
      nachgeladen werden. Das autocreate-Modul interpretiert das
      UNDEFINED-event, welches von jedem Modul gestartet wird, erzeugt ein
      Ger&auml;t (device) und bei Bedarf ein FileLog sowie
      SVG-Eintr&auml;ge.<br>

      <b>Hinweis 1:</b> Ger&auml;te werden mit einem eindeutigen Namen erzeugt,
      der den Typ und eine individuelle ID f&uuml;r diesen Typ enth&auml;lt.
      Wird ein Ger&auml;t umbenannt (<a href="#rename">rename</a>), wird
      gleichzeitig das automatisch erzeugte FileLog und die SVG Ger&auml;te
      unbenannt.<br>

      <b>Hinweis 2:</b> Durch das Setzen des <a
      href="#disable">disable</a>-Attributes kann die automatische Erzeugung
      ausgeschaltet werden. In diesem Fall ist ausschlie&szlig;lich die oben
      erl&auml;uterte Umbenennung aktiv. Der <a
      href="#createlog">createlog</a>-Befehl kann zum Hinzuf&uuml;gen von
      FileLog und SVG eines bereits definierten Ger&auml;tes benutzt werden.
      <br>

      <b>Hinweis 3:</b>Es macht keinen Sinn, die Instanz dieses Moduls mehrmals
      zu erzeugen.

    </ul>
    <br>

    Beispiel:<PRE>
    define autocreate autocreate
    attr autocreate autosave
    attr autocreate device_room %TYPE
    attr autocreate filelog test2/log/%NAME-%Y.log
    attr autocreate weblink

    <a name="autosave"></a>
    <li>autosave<br>
        Nach der Erzeugung eines neuen Ger&auml;tes wird automatisch die
        Konfigurationsdatei mit dem Befehl <a href="#save">save</a>
        gespeichert. Der Standardwert ist 1 (d.h. aktiviert), eine 0 schaltet
        die automatische Speicherung aus.<br>
        <b>Achtung:</b> Dieses Attribut ist unerw&uuml;nscht, bitte stattdessen
        das global autosave Attribut verwenden.
        </li><br>

    <a name="device_room"></a>
    <li>device_room<br>
        "Schiebt" das neu erstellte Ger&auml;t in diesen Raum. Der Name kann
        die Wildcards %NAME und %TYPE enthalten, siehe oben stehendes
        Beispiel.</li><br>

    <a name="filelogattr"></a>
    <li>filelog<br>
        Erstellt ein Filelog welches zu einem Ger&auml;t geh&ouml;rt. Der
        Dateiname darf die Wildcards %NAME und %TYPE enthalten, siehe oben
        stehendes Beispiel. Das Filelog wird in den gleichen Raum "geschoben"
        wie das zugeh&ouml;rige Ger&auml;t.</li><br>

    <a name="weblinkattr"></a>
    <li>weblink<br>
        Erzeugt ein SVG, welches mit dem Ger&auml;t/Filelog verkn&uuml;pft
        ist.</li><br>

    <a name="weblink_room"></a>
    <li>weblink_room<br>
        "Schiebt" das neu erstellte SVG in den bezeichneten Raum. Der Name kann
        die Wildcards %NAME und %TYPE enthalten, siehe oben stehendes
        Beispiel.</li><br>

    <li><a href="#disable">disable</a></li>
      <br>

    <a name="ignoreTypes"></a>
    <li>ignoreTypes<br>
        Dies ist ein Regexp, um bestimmte Ger&auml;te zu ignorieren, z.b. der
        Funk-Heizungsthermostat (FHT) des Nachbarn. In dem Ausdruck k&ouml;nnen
        mehr als ein Ger&auml;t &uuml;ber die normale Regexp-Syntax angegeben
        werden. Beispiel:<br>
        attr autocreate ignoreTypes CUL_HOERMANN.*|FHT_1234|CUL_WS_7<br>
        Das Wort "Types" ist etwas irref&uuml;hrend, da der Ger&auml;tename
        gepr&uuml;ft wird, und nicht der Typ.
        </li><br>

    <a name="autocreateThreshold"></a>
    <li>autocreateThreshold<br>
        Eine Liste of &lt;type&gt;:&lt;count&gt;:&lt;interval&gt; tripeln. Ein
        neues Device wird nur dann erzeugt wenn es mindestens <code>count</code>
        Events f&uuml;r den TYPE <code>type</code> in den letzten
        <code>interval</code> Sekunden gegeben hat.<br>
        Beispiel:<br>
        <code>attr autocreateThreshold LaCrosse:2:30,EMT7110:2:60</code>
        </li>

  </ul>
  <br>

  <a name="createlog"></a>
  <b>createlog</b>
  <ul>
      Dieser Befehl wird f&uuml;r ein manuelles Hinzuf&uuml;gen eines Logfile
      oder eines SVG zu einem vorhandenen Ger&auml;t verwendet.
      <br><br>
      Dieser Befehl ist Bestandteilteil des autocreate-Modules.
  </ul>
  <br>

  <a name="usb"></a>
  <b>usb</b>
  <ul>
      Verwendung:
      <ul><code>
        usb scan<br>
        usb create<br>
      </code></ul>
      Dieser Befehl durchsucht das /dev-Verzeichnis nach angeschlossenen
      USB-Ger&auml;ten und versucht gleichzeitig sie zu identifizieren. Mit dem
      Argument scan wird eine Liste von ausf&uuml;hrbaren FHEM-Befehlen
      zur&uuml;ckgegeben. Das Argument create gibt keine Liste o.&auml;.
      zur&uuml;ck, die Ger&auml;te werden stattdessen erzeugt.<br><br>

      Es ist zu beachten, dass ein CUL immer noch manuell in den
      HomeMatic-Modus umgeschaltet werden muss. <br><br>

      Unter Linux wird gleichzeitig mit dem lsusb-befehl &uuml;berpr&uuml;ft,
      ob nichtgeflashte CULs angeschlossen sind. Ist dies der Fall, ruft Linux
      CULflash mit den geeigneten Parametern auf (oder zeigt den
      CULflash-Befehl an, falls scan aufgef&uuml;hrt wurde).
      Pro usb Befehl wird nur ein Ger&auml;t geflasht.<br><br>

      Dieser Befehl ist Bestandteilteil des autocreate-Modules.
