✕ Remove zone
What it is
The ✕ at the end of a zone row. Its label says Remove zone N.
What to enter
Press it to remove the zone. Rooms on later zones move down one number.
What it changes
In the app: The room on that zone loses its amplifier controls at the next Save & Deploy.
In the house: The hub no longer gets that zone at the next Save & Deploy.
If it goes wrong
The last zone cannot be removed; it is emptied instead.
