Delete this floor (×)
Screen: Rooms
What it is
The × at the right end of the floor card. Its tooltip says Delete this floor.
What to enter
Press it. A box opens that lists every room on the floor and what is in each room. Nothing is removed until you press Delete floor.
What it changes
In the app: After Delete floor and the next Save & Deploy, the floor and all its rooms are gone from every phone.
In the house: After the next Save & Deploy the hub no longer has those rooms or their devices.
If it goes wrong
Press Cancel if the list is not what you expected. Deploy history keeps the previous version, so a floor deleted by mistake can be got back from there.
