The little box that makes light speak.
Plug it in and every room learns the day: clear in the morning, steady for focus, warm when the house gathers, low when it’s time to rest. It runs entirely in your home — no cloud account, no monthly fee, nothing to babysit.

What it holds
Your home’s whole day, on-box.
This is the curve your body was built for — sun by day, fire at night. LightHub keeps it running in every room without asking you to manage the sun.
Setup

Plug it in

Open the app
Rhythm finds the box on its own and asks one thing: how should each room feel through the day?

Let it speak
Add your bulbs once. LightHub keeps the right signal moving, room to room, morning to night.

Fair questions
Asked by people like you.
Do I need to replace my bulbs? +
Probably not all of them. If you own Philips Hue or Home Assistant lights, they join as they are. Starting fresh? Any Matter bulb works, and the good ones cost about $10 — our guides keep a short shopping list.
Will it work when the internet is down? +
Yes. The whole day runs on the box, on your network. Rhythm never needs a cloud to keep your rooms speaking — internet outages, server outages, and subscription price hikes are simply not part of the product.
What if I want bright light at 11 PM? +
Take it. The override is instant, and it is never an argument — the room gives the task what it needs, then picks the rhythm back up on its own. You never re-teach anything.
Do I need a LightHub to try Rhythm? +
No — the app is free, and if you already own Hue or Home Assistant lights your first room can start speaking tonight. The LightHub is what makes it whole-home, local, and effortless.
When does it ship? +
LightHub is in pre-order. Reserve your spot and you will be first in line when orders open — we will email you before anything is charged.
One small box.
A fluent home.
