Port (KNX)

What it is

The Port box next to the KNX gateway IP.

What to enter

The gateway's port. KNX IP normally uses 3671; leave it unless the gateway is set differently.

What it changes

In the app: Nothing the owner sees directly.

In the house: The hub connects to the gateway on this port at the next Save & Deploy. An empty box is sent as 3671.

If it goes wrong

If the hub cannot reach the gateway, check the port in the gateway's own settings.
