01THE HOUSEHOLD OPERATING SYSTEM

A home that works as one.

One Core - a small box for the shelf - and a few stick-on senses, none with a camera. Plug them in and the house quietly learns how it runs. By day three, it knows the kettle.

Reserve your Luma How it works
LUMA · THE JOURNAL21:46

The house has settled. Last lights low, everyone tapped in.

◆  QUIET HOURS · HOLDING TO 6:30
02THE JOURNAL

Every suggestion comes with a reason.

The Journal is your home’s memory. Every line traces back to what the house actually noticed.

WHAT THE HOUSE NOTICED
21:08 - Maya tapped in home 21:12 - lounge reads lived-in 21:40 - washer: cycle ended
WHAT LUMA SAID21:46

The laundry finished while everyone was out - I’ll hold the reminder for morning.

◆  SOURCE: WASHER POWER TRACE · HOME PASS
WHAT YOU CAN DO
Remind at 6:30 Dismiss

A light, it’ll handle. A door, it asks.

03TWO WAYS TO RUN A HOME

Connected by default. Off‑grid by choice.

CONNECTED: THE DEFAULT
It reaches you anywhere.

Whatever travels is sealed so only your family can read it - even we can’t.

OFF-GRID: THE CHOICE
It stands alone.

One switch, and the house needs nothing beyond its walls.

The switch is real - and it goes both ways.

Flip it, and the cloud simply lets go of your home. Nothing moves, nothing is lost.

Private either way. The ledger of what the cloud can see fits on one page. READ THE TRUST LEDGER  →
04HOUSE RULES
01
One Luma, not a cast of bots.

It remembers, keeps the family’s notes, looks after routines - one memory, kept at home.

02
Comfortable saying “probably.”

It tells you how sure it is. No confident guesses.

03
Yours, with or without us.

The Journal and keys live on the Core. Connected, the cloud carries what it can’t read; off-grid, there’s no cloud at all.

05ORDINARY REPORTS

Small things, noticed in time.

One day, as the Journal wrote it.

Quiet hours - holding to 6:30.

08NO SMALL PRINT

Straight answers.

The questions people actually ask.

Where your home livesOn the Core, on your shelf - not on someone else’s servers.
Who it watchesRooms read as lived-in, never who. People appear only by saying so: a tap at the door, a note with their name.
CamerasNone. The senses have no lenses.
MicrophonesNone.
The cloudOptional. Connected, it carries what it can’t read. Off-grid, it doesn’t exist. Switch either way; the Journal stays on your shelf.
If the internet goes outYour home keeps working. Off-grid, it never notices.
What Luma asks firstReversible things only - a light, it’ll handle. A door, it asks.
