iPhone Presence Detection with hping3 and ARP

@David_Graeff I’ve upgraded to the latest openHAB build today and tried to use the new Network binding. I’m stuck at

java.lang.IllegalArgumentException: Cache expire time must be greater than 0

thrown by this code part.

Here are my configuration details:

Thing   network:pingdevice:BirkePC  [ hostname="192.168.0.2", retry=1, timeout=5000, refreshInterval=10000 ] 

grafik

(the refresh_interval is a relic from the old binding config)

I could try to delete the cache, configuration or reinstall the Binding but I guess this could be a real bug that needs to be dealt with. Any ideas?
