Hi yphyph01,
please add busaddr=15.10.1 (or any other free KNX address) and ignorelocalevents=true to your KNX configuration and test it.
# KNX IP connection type. Could be either TUNNEL or ROUTER (optional, defaults to TUNNEL)
# Note: If you cannot get the ROUTER mode working (even if it claims it is connected),
# use TUNNEL mode instead with setting both the ip of the KNX gateway and the localIp.
type=ROUTER
# Local endpoint to specify the multicast interface, no port is used (optional)
localIp=192.168.0.180
# Local KNX Binding bus address.
# Use it, when two or more openHAB Instances are connected to the same KNX bus.
# (optional, defaults to 0.0.0)
busaddr=15.10.1
# Ignore local KNX Events, prevents internal events coming from
# 'openHAB event bus' a second time to be sent back to the 'openHAB event bus'.
# Note: To send back events second time is a Bug, but for backward compatibility, the behavior is not changed.
# For new installations, its recommend to set "ignorelocalevents=true"
# (optional, defaults to false)
ignorelocalevents=true
Furthermore enable debug for KNX in openHAB 2 console:
log:set DEBUG org.openhab.binding.knx
whith log:tail you’l see the output.
