    If the attributes interval_allFB and interval_history are not defined (or 0), their internal polling is disabled.  
-   Clearly you can also define the polling interval outside the module with the "at" command.

    Wenn die Attribute interval_allFB und interval_history nicht definiert sind (oder 0), ist das interne Polling deaktiviert.
-   Nat&uuml;rlich kann das Polling auch mit dem "at" Befehl ausserhalb des Moduls definiert werden.
