Minimum KNX set-up?

I don’t think that the TPUART USB Adapter will work directly with ETS

I know that it will work if you use it with KNXD to create a “home-made” KNX/IP Router on a Linux host. Then, you can use multicast to connect your ETS to the KNXD.

maybe right but im electronic student i see inside the tpuart its have a uart converter ic and rs232 chip
isnt any way to make myself a simple usb to knx converter that reconised by ets?
i cant find same project in google

yes, of course there is!
good luck :stuck_out_tongue:
