KNX Changed from Tunnel to Router makes a lot of Loginfo?

Hello Guys.
I’m using KNX Binding version 1.9 (installed from PaperUI on OH2)
It worked correctly, when using it in Tunnel mode, but now i wanna set it to be in Router Mode, this makes a million lines in my log file - but the communication works, i get this:

[Link notifier] process link unsupported APDU service - ignored, service code = 0x240

and also

Ignoring local Event, received from my local Source address 15.15.2 for Group address 0/2/100.

I’ve set the ignorelocalevent=True in the config file, also when running Tunnel Mode.

Why is all this now generated? Pretty annoying


First of all, make sure that the syntax is correct in your /etc/openhab2/services/knx.cfg


(“ignorelocalevents”, not “ignorelocalevent”)

Add also a Local KNX Binding bus address in the same file:


Make sure that this PA is free in your existing KNX Bus.

If these 2 changes do not help, let me know your KNX/IP Router model as well as put the binding in debug mode and post some logs.

ssh openhab@localhost -p 8101 (with password habopen)
log:set TRACE org.openhab.binding.knx
log:set TRACE

Have you enabled “Reliable Communications” in your ETS for your KNX/IP Router? Try disabling this option to see if the “unsupported APDU service” exception goes away.


Check - done correct


Will test it…

The interface is ABB Ipr/s 2.1 ip router

Hello again.
Here’s the log from the OH2 where the KNX binding are in debug mode… I can’t find the “Reliable Communication” in the ABB Router configuration. I attached my router configuration…

How to disable the log for the KNx binding again? It spams my log file :slight_smile:

events.log.pdf (35.1 KB)
openhab.log.pdf (205.8 KB)


Enter in Karaf console: “ssh openhab@localhost -p 8101” (password: habopen)
Check log levels: "log:list"
Set KNX to Error: "log:set ERROR org.openhab.binding.knx"
Set Calimero to Error: “log:set ERROR

Your log looks good. You can safely ignore the warnings.


OKay… Thanks :slight_smile:
