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.
