Presence

Presence and geofence

1
Arrival warm-light handoff on the hall mmWave A 60 GHz mmWave sensor in the entry hall turns on a 2400 K two-fixture scene the moment you step in, holds it for 12 minutes, and refuses to fire in daylight. Total detect-to-light latency measured at 850 ms. matter 850 ms

Light

Light and daylight

2
Daylight harvesting: electric light follows the window The ceiling circuit in a south-facing office trims itself down as daylight rises, holding a constant 500 lx on the work plane. Measured saving on a clear spring day was 41 % of the lighting energy against a fixed-100 % baseline. matter 8000 ms Lux-adaptive blinds that hold 300 lx on the desk, not a fixed percentage A closed-loop controller reads a desk lux sensor every 90 seconds and moves the blind to the position that keeps the desk between 250 and 400 lx. On an overcast day it opens fully; on a bright February noon it sits at 22 % open. matter 90000 ms

Climate

Climate and air

1
Night cooling purge that pulls in cool air only when it helps On summer nights the bedroom window opens automatically only when outdoor air is at least 3 °C cooler than indoors and indoor CO₂ is above 900 ppm, closing at 05:30 or when outdoor temperature rises within 1.5 °C of indoor. matter 180000 ms

Energy

Energy and load

2
Storm reserve: pre-charge the battery and shed discretionary loads When a wind warning or a grid-frequency excursion is detected, the battery is charged to 95 %, discretionary loads are shed, and the reserve floor is raised from 20 % to 60 % so a 6-hour outage does not leave the house dark. matter 300000 ms Divert solar surplus to the hot water cylinder instead of exporting at 4 ¢ The immersion heater steps up in 400 W increments to absorb PV surplus, holding grid import between -50 W and +150 W for four hours. In a 4.2 kWp array this captured 6.8 kWh on a clear April day instead of exporting it at the feed-in rate. matter 60000 ms

Safety

Access and safety

1
Door left open: timed escalation instead of an instant alarm A door left open escalates in three stages — a soft chime at 90 seconds, a spoken reminder at 5 minutes, a repeated alert at 15 minutes — because a fridge run should not sound like a burglary. matter 90000 ms
