Physical Addr (KNX)

What it is

The Physical Addr box next to the KNX port. It shows 15.15.200 in grey when empty.

What to enter

The KNX physical address the hub should use on the bus, in the form area.line.device, for example 15.15.200. It must not be used by any other KNX device.

What it changes

In the app: Nothing the owner sees directly.

In the house: The hub uses this address on the KNX bus at the next Save & Deploy. An empty box is sent as 15.15.200.

If it goes wrong

If two devices on the bus share this address, KNX traffic can fail. Pick a free address from the ETS project.
