Guest
Screen: Rooms
What it is
The last line in the Who can use menu. Guest is the shared PIN for visitors, not a person.
What to enter
Press it to let guests use the room, or press again to stop them.
What it changes
In the app: A guest signing in sees only the rooms ticked for Guest, at the next Save & Deploy. A room hidden on the phone is not given to guests.
In the house: The hub's guest room list changes at the next Save & Deploy.
If it goes wrong
If a guest sees rooms they should not, untick Guest on those rooms. Everyone never includes the guest.
