ALL|OFF automatically powers down HVAC and lighting the moment a hotel room's empty, then gently welcomes everything back on as the guest returns. No app, no habit change, no guest friction — just a genuine, measurable cut in running costs.
Door sensor, motion latch, and exit timer — working together, only the small and discreet motion sensor visible to the guest.
Key-card switches only know whether a card is in the slot — not whether anyone's actually in the room. Guests learn the workaround fast, and the savings quietly disappear.
Door sensor triggers — lights and HVAC switch on automatically.
Guest controls lights and AC normally. No re-triggering needed.
Door sensor fires again. A 5–10 minute exit-delay timer begins.
No motion detected → lights and HVAC switch off. Temperature is still monitored for safety.
Wireless sensors talk to a single controller hidden near the fuse box — nothing visible changes in the room except a light that now switches itself off.
The controller hides inside or alongside the fuse box, wired into existing circuits. Two outputs control lighting and AC/heat independently.
Discreetly senses whether the room is occupied. A 10-year battery life means almost zero maintenance once fitted.
Triggers welcome lighting the moment a guest enters. Fire-rated and fitted invisibly into the door frame.
