01 · Almost home

Keys in hand. House dark.

Lux is already awake on your keyring, waiting for your front door.

02 · Lux says hi

Your keys say "I'm here."

A tiny Bluetooth chip in the fob sends a quiet signal. The hub by your door hears it the second you step inside.

03 · Lights on

The room wakes up with you.

The hub tells your smart lights to switch on, and the light line on your keys glows to say it worked.

04 · Off when you leave

Walk out. Lights out.

Leave with your keys and Lux turns everything off behind you. No phone, no app, no switch.

The design

Small enough to disappear on your keys.

Cut from aluminum and finished in matte, so it shrugs off scratches from everything else on your ring. The light line doubles as the only button: press it to switch lights by hand.

Why Lux

Your phone shouldn't be your house key.

Right at the door

Lux triggers as you walk in, not a block away when your phone guesses you're close.

For everyone at home

Kids, parents and guests get a welcome home too, phone or no phone.

Lights off when you leave

Walk out with your keys and everything switches off behind you.

Works with your lights

Pairs with Matter-compatible smart lights you already own. Nothing to rewire.

A year on one battery

A replaceable coin cell keeps Lux going for over a year.

A fob for each person

One hub, many keychains, and a different light scene for whoever walks in first.
