Make a room
Screen: Rooms
What it is
A line in the ⋯ menu of a sub-room.
What to enter
Press it to turn the sub-room back into a main room.
What it changes
In the app: In the app, the room becomes a full-width gold tile instead of a half-width tile under its parent, at the next Save & Deploy.
In the house: The hub does not use the main-room link. The room and its devices work the same either way. The link only changes how the app draws the tiles, and how the Join Map lists the room.
If it goes wrong
If it was a mistake, choose Make a sub-room of… again.
