Pitch Deck — March 2026

Levellume™

Ambient IoT hardware that makes home energy and water consumption visible at a glance. No app, no screen, no learning curve — just light.

02 / 10
The Problem

Energy use is invisible. Nobody sees it.

Invisible consumption

Energy and water data exist, but they're buried behind apps, portals, and number-heavy dashboards nobody opens.

Rising bills, no action

Most people only find out what they used when the bill arrives.

Water is invisible too

Water use only shows up on the yearly bill. Where the meter provides it, the light shows it within minutes.

03 / 10
The Insight

A meter you can see changes behavior.

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 applies that principle with modern hardware and design.

The Product

A wall fixture that shows what your home is doing.

Green = low usage. Yellow = moderate. Red = high. Blue = water use. One glance, zero effort.

Cryo

From €—

Black aluminium. Slim, architectural, invisible against the wall.

Ligna

From €—

Natural oak. Warm, Scandinavian, designed to blend into living spaces.

Circa

From €—

Frosted acrylic halo. 360-degree ambient glow. A statement piece.

How It Works

Plug in. Connect. See.

Setup

  • Hub connects to the P1 port on the smart meter (no electrician needed)
  • WiFi pairing via browser-based onboarding
  • Fixture mounts on any wall — powered by USB-C
  • Water via the P1 port, where the meter provides it

Technology

  • ESP32-S3 microcontroller with custom PCB
  • ESP-NOW protocol for instant hub-to-fixture communication
  • Cloud: Firebase (Auth, Firestore, Hosting, Functions)
  • OTA firmware updates — devices improve after purchase
