Sixth and last room, drawn straight in the perspective view: the door is where you stand, the window is on the far wall, the shower in the far corner. Same rules: tap anything with a label, the drawing reacts, the card shows that device and what we would automate. The bathroom is a routine room: the towel rail and the floor are warm before you get up, the mirror light meets you, the extractor fan follows the humidity after a shower, a sensor under the basin shuts the water off if it ever gets wet, and at night a strip at the skirting lights your way instead of the ceiling. Start the shower from its card to watch the fan react.
Fourteen things to tap: main lights, mirror light, the window blind, the heated towel rail, the extractor fan with its humidity sensor, the shower, the smart scale, the toothbrush charger, the leak sensor under the basin and the water valve it closes, the Airwick on the shelf, the floor heating dial, the night light at the skirting, the wall tablet by the door. In the day: the rail and the floor warm up before you are awake, the mirror light comes on when you walk in, the shower pushes the humidity up and the fan runs until it is back under 60%, the scale and the toothbrush report in, the Airwick puffs every 36 minutes, at noon the leak sensor runs its test and the valve closes for ten seconds, the rail does an evening round, lights go warm and dim late, and after 23:00 only the night light answers to motion.
