Presence

Presence and geofence

1
Guest mode: local recording only, cameras pause in private rooms One boolean flips the house into guest mode: indoor cameras stop recording and physically close their privacy shutters, cloud uploads pause, and the hallway still lights on presence. Mode exits automatically 6 hours after the last guest device leaves Wi-Fi. wifi 2200 ms

Climate

Climate and air

1
Pollen lockout that closes windows before the count spikes Using a local pollen sensor plus a 3-hour forecast, the automation closes windows 40 minutes before a predicted spike and hands ventilation to the HEPA supply unit, then reopens when the outdoor count falls below 20 grains/m³ for 30 minutes. wifi 2400000 ms

Energy

Energy and load

1
EV charging that yields to the oven without stranding the car The charger modulates from 6 A to 16 A to hold total house load under the 63 A main fuse, pausing rather than stopping when the oven or dryer starts, and guarantees 40 % charge by 07:00 whatever the household does. wifi 15000 ms

Water

Water and leak

1
Rainwater tank top-up and pump protection on a level probe A pressure-based level probe keeps the 3 000 L rainwater tank between 40 % and 85 %, tops up from mains only during the cheap night window, and cuts the pump below 15 % so it never runs dry and burns its seal. wifi 3600000 ms

Safety

Access and safety

1
Package watch: porch event to a 40-second clip, no continuous recording The porch camera records only when the mailbox or porch contact opens, producing a 40-second clip with a 10-second pre-roll, and pushes a still to the household. Between events the camera is in a low-power state with no stream and no cloud session. wifi 3000 ms
