Duplicate source events which may occur within the time given by the global attribute <a href="#dupTimeout">dupTimeout</a>,
will be suppressed in order to avoid overhead. The value of this attribute is to be changed with great care, as it
affects other parts of FHEM, too.

Dabei werden die von FHEM2FHEM in Form von Events weitergereichten entfernten Device-Readings in eigene Readings übernommen.
Identische Events, die innerhalb der durch das globale Attribut <a href="#dupTimeout">dupTimeout</a> vorgegebenen Zeit auftreten,
werden zusammengefasst, um überflüssige Events zu verhindern. Dieses Attribut ist mit bedacht zu ändern, da sich seine Auswirkungen
auch auf andere Bereiche von FHEM erstreckt.
