Y'all should try to scan a large subnet of an ISP with lots of corporate clients. You can't imagine how many open (as in r/w access) KNX systems you'll find. Lights, doors, fire alarms, cameras, thermostats, speaker systems, displays, HVACs and shutters. There are too many to responsibly disclose to the parties affected. Some buildings are so connected one could cause quite a havoc.
