KNX/TP sniffer

[morkovka]

Hi,

Sometimes it can be useful to have the ability to capture/sniff the telegrams over KNX/TP - for example in case of a storm/loop of some sort.

Is there something we can use to do this, kind of a tcpdump for KNX?

KNX is a multicast, everything goes everywhere. You can only use filters between lines

[morkovka]

Ok.

Is it possible to display (sniff/capture) the telegrams on the bus?

[Daniel]

You have KNX statistics which shows you the traffic.

[morkovka]

It shows me statistics - not the traffic.

I want to see:
- sender IA
- destination IA/GA
- type of request - e.g. read/write
- data

If you're familiar with network tools such as 'tcpdump', 'wireshark' - I mean the same thing, just for KNX.

There is app for it but has to be uploaded manually via FTP to apps. Unzip and upload to data folder
