KNX Gateway IP (old, not shown)
What it is
An old box for the KNX gateway address. In this configurator version the code that draws it is never called, so it does not appear on any screen.
What to enter
Nothing. It is not shown.
What it changes
Nothing, because it is not shown. (It would set the KNX gateway address the hub uses.)
If it goes wrong
Set the KNX address on its tile under Systems in this home on step 1.
