Defines a CanOverEthernet device. FHEM will start listening to UDP broadcast
on port 5441.

Erstellt ein CanOverEthernet device. FHEM empfängt auf Port 5441 UDP broadcast.
<br>
Beispiel:
<ul>
<code>define coe CanOverEthernet</code>
</ul>
Die eingehenden Daten werden als readings in eigenen COE_Node devices gespeichert.
Diese devices werden automatisch angelegt, sobald Daten dafür empfangen werden.
