Bus Monitoring

Bus Monitoring

KNXmap supports two different monitoring modes:

• Bus monitoring: prints the raw messages received from the KNX bus.

knxmap monitor 192.168.1.100

• Group monitoring: prints all group messages received from the KNX bus.

knxmap monitor 192.168.1.100 --group-monitor

These monitoring modes can be useful for debugging communication on the bus. Additionally, they can be used for passive information gathering which allows to identify bus devices without sending messages to any individual or group address. Especially motion sensors or other devices that frequently send messages to the bus can easily be identified via bus monitoring.
