Hello,

I have a big problem, my lm4 missed on regular base knx telegrams on the bus.

I don't see the messages in the lm4 objects logs, but when i use another ip devices with ets5 logging i see these telegrams.

How its possible my lm4 missed some telegrams and how to solve this?

What is the bus load in %? Do you have any KNX errors in the log?

Can you show statistics from System Config -> Network -> KNX statistics?

That's really low load. There's a bump in there, maybe you have some scripts which are sending many telegrams at once and causing collisions on the bus?

The peak every 15 minutes is not the problem, because that are read telegrams from my visualisation software (domovea). I activated these reads some weaks ago, but before i had also this missing telegram problem.

It looks like its started by the changed libraries send by the developer:
