Screen: Rooms
What it is
The first line in the room's ⋯ menu.
What to enter
Press it. A copy named <room> copy is added straight under the room, with the same devices.
What it changes
In the app: After you rename it and Save & Deploy, the copy is a new room tile in the app.
In the house: The copy's devices come with their KNX addresses and Crestron joins left empty (an AC's unit too), because a copied address would drive the first room. The hub gets the copy at the next Save & Deploy.
If it goes wrong
The copy will show addresses to fill until you fill them in Room Devices. Give the copy its own name, or Save & Deploy stays off.
