A holiday let run hands-off, drawn as one studio seen from the entrance: the door with its keypad is beside you, the bed is against the far wall, the kitchenette along the left, the sofa facing the TV on the right. Same rules: tap anything with a label, the drawing reacts, the card shows that device and what we would automate. This is changeover day: guests leave at ten, the cleaner has a code until three, the next guests get theirs at check-in. Nothing here needs you to be there, and the noise monitor only reads a level, never audio.
Thirteen things to tap: the robot vacuum, the guest tablet with the bookings and the house guide, the smart lock with its per-stay codes and the key safe, the noise monitor, the occupancy sensor, heating and hot water, the lights, the window blind, the TV in guest mode, smoke and CO, the leak sensor and valve under the sink, the cleaner's cupboard with the checklist, the energy meter per stay. Through the day: the tablet walks the guests out, the code dies at ten and the room goes to eco, the cleaner's code opens the door, the leak sensor runs its test, the checklist comes in with a photo, the room warms up for the arrival, the new code is sent, the guests walk in to lights and the guide, the blind drops at dusk, and a loud late evening gets one polite message before anyone calls you.
