sorry … I’ll summarize it.
Raspi pi3B +, openhabian and openhab 2.4 installed.
now I wanted to interface it with the knx system, via my USB stick.
from the config openhabian menu, I install knxd, and modify the file to make it work with usb and not TPUART.
if I use ETS, everything works but the knx address of raspi is 0.0.1 and not the one I set as --eibaddr.
if I use openHAB 2.4, entering tunnel mode and addressing 127.0.0.1 above, it doesn’t work.
If I use router mode, and default address 18.104.22.168:3761/UDP, the IP gateway becomes online, but if I try to bind with KNX devices it does not find them and I cannot control the system.
Thanks and sorry for the long post.
