I've attached the Jigsaw to my KNX installation by connecting the TP connection directly to the bus.
Seems the Jigsaw cannot start that way of communication.
On the other hand, when I try it by using the KNP IP gateway, it IS working!
So, how can I enable the Jigsaw's internal KNX TP bus connection instead of using the IP based connection?
