Levellume builds ambient IoT hardware that turns real-time utility data into beautiful light. No app, no screen, no learning curve — just a glance.
Levellume connects to your home's smart meter and water meter, then visualizes consumption through ambient LED light. Green means low usage. Yellow means moderate. Red means high. Water use shows in blue, where the meter provides it. No app to open, no numbers to read — homeowners just glance at a beautiful wall fixture.
Systems thinker Donella Meadows told the story of Dutch homes where the electricity meter hung in the front hallway: those households used noticeably less than identical homes with the meter in the basement. Levellume puts that hallway meter back — as light.
Black aluminium fixture. Slim, architectural, invisible against the wall. For the home that takes design seriously.
Natural oak frame with warm wood finish. Designed to blend into living rooms and hallways where presence matters.
Frosted acrylic halo with 360-degree ambient glow. A statement piece that belongs in the center of a home.
Levellume is built by two co-founders — one based in Antwerp, one in the San Francisco Bay Area. Between them, they cover hardware design, firmware engineering, cloud infrastructure, web development, and product design.
The team has grown to include roles in engineering, sales, and operations. Every part of the product — from the PCB layout to the checkout page — is designed and built in-house.
The entire platform is designed for reliability and low operational cost. Hardware connects to cloud services with zero ongoing server management.
