KNX/TP: Transmitter Error (send 0 receive 1)
#8
You have a very low number of repeats so it's not a problem. Most likely the warning appears when LM is sending many telegrams at once.

You can install Group monitor app in LM and see all telegrams in real-time. It highlights a different kind of repeats - when the same value is sent multiple times.

The same advice applies:
You should either use virtual group addresses or disable "write to bus" option where applicable. In scripts use grp.update/grp.checkupdate for such group addresses. Use grp.checkwrite where possible to lower the bus traffic. Adjust send delta for Modbus devices if any.
