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.
<br>
<ul><code>
define Mythz THZ /dev/ttyUSB0@115200 <br>
define atMythzFB at +*00:05:00 {fhem "get Mythz sGlobal","1";;return()} <br>
define atMythz09 at +*08:00:00 {fhem "get Mythz sHistory","1";;return()} <br>
define FileLog_Mythz FileLog ./log/Mythz-%Y.log Mythz <br>
</code></ul>

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.

<ul><code>
define Mythz THZ /dev/ttyUSB0@115200 <br>
define atMythzFB at +*00:05:00 {fhem "get Mythz sGlobal","1";;return()} <br>
