You can see your aunt's newest recipe—and how many likes it got from the other side of the world. You can't see when your own home is burning money through power and water waste that happens every day, in almost every house. **Level Lume changes that.**

**Your home's energy and water — felt, not read.**

The problem

Advanced metering now reaches most U.S. homes, but the data hides in apps nobody opens and basement displays nobody passes. Decades of feedback research show that when consumption is visible where people live, use falls up to 30%—no new tariffs, no new appliances. The clarity was never the issue. The interface was.

How it works

Level Lume is a wall-mounted architectural light plus a small Wi-Fi Utility Hub. The hub plugs in and pairs wirelessly with sensors homeowners already own—Flume water monitors, HomeWizard and Shelly energy meters, plus optional utility and solar-platform feeds. No electrician. Setup in under ten minutes. Live data streams to the fixture as rising color bands: **orange** = grid draw, **green** = solar production/return, **blue** = water flow. Fill height is today's use versus the daily target; animation speed reflects real-time draw; at midnight the canvas resets. A millimeter-wave radar sensor wakes the display when someone walks past and fades it when the hallway empties. No digits on the wall—a child understands it at a glance. Tap the fixture with a phone (NFC) to open the companion app (iOS, Android, PWA) for costs, history, targets, and an **Energy Coach** that turns patterns into actionable savings.

What's novel

Universal, non-numeric, multi-utility ambient feedback in furniture-grade design. Competing in-home displays are single-utility plastic gadgets; competing apps require deliberate attention. Level Lume replaces both with light you notice in passing, plus depth on demand. Three collections—precision aluminum, natural oak, frosted acrylic Circa—position the product as architectural lighting, not a rebate device.

How it's built

Working prototype demonstrated. Hub and fixture run ESP32 microcontrollers with ESP-IDF firmware; PCBs designed in EasyEDA for direct EMS manufacturing; enclosures in Fusion 360; LED optics, mmWave radar module, and standard LED drivers—all commodity electronics. Contract PCBA and enclosure assembly; hub bundled in every unit; U.S.-first fulfillment, phased international expansion.

Cost & market:

Retail €249–599 (approx. $269–$649) across three collections—Circa, Cryo, and Ligna—with the hub included. Positioned alongside premium smart-home lighting and above single-utility in-home displays ($80–150), while delivering multi-utility awareness neither category offers. Volume BOM leverages commodity ESP32 electronics and standard EMS for healthy hardware margin. Addressable market: 100M+ U.S. homes with advanced metering plus mature European smart-meter markets; rising rates; drought-stressed regions; overnight leaks that flood floors before anyone notices. Visibility-driven savings alone repay hardware in one to two years at typical U.S. tariffs—before value from a single caught leak.

Level Lume: your home's elements, in motion.
