Flagship Platform

The ER0 / ER0S EdgeBox.

An industrial IoT gateway that bridges field-side Bluetooth Mesh / NLC lighting, Modbus RTU devices and 0–10 V / DI-DO I/O to Modbus TCP, BMS or cloud over a single PoE cable. The ER0S variant adds an integrated 5G DECT NR+ radio for long-range sensor backhaul — no SIM, no cellular subscription.

Core Technology

Three foundations, one platform.

The EdgeBox is built on a wireless stack that combines short-range and long-range connectivity with energy that generates itself — so networks stay reliable without batteries, base stations or SIM cards.

Bluetooth Mesh & NLC

Networked Lighting Control over Bluetooth Mesh — provisioning, scenes, scheduling and energy monitoring from a phone, scaling to 1,000+ nodes.

100 m+ LoS · Bluetooth NLC profile

DECT NR+ (5G)

ETSI DECT-2020 NR standard on license-exempt spectrum — self-healing, decentralized mesh built for up to a million nodes per square kilometre.

2 km LoS · <1 ms latency · no SIM

Self-Power & Harvesting

Battery-free switches and sensors harvest kinetic and ambient energy, proxied straight into the mesh — no wiring, no batteries, zero maintenance.

Applications

Built for two worlds.

Bluetooth NLC professional lighting — warm cabinet and shelf lighting in an elegant interior
01 — Professional Lighting

Lighting control, elegantly wireless.

Bluetooth Mesh · NLC

Networked Lighting Control over Bluetooth Mesh — provisioning, dimming, scenes and scheduling from a phone, driven by self-powered switches. One platform from indoor luminaires to city-wide street lighting.

  • Indoor luminaires — tunable white / RGBCW dimming, scenes, occupancy & daylight response
  • Outdoor & street lighting — city-scale scheduling, diagnostics, energy savings
  • Self-powered switches — battery-free, install anywhere, no wiring
DECT NR+ industrial equipment and environmental monitoring
02 — Data Collection

Long-range sensing, no base station.

DECT NR+ · 2 km LoS

License-exempt DECT NR+ backhaul into the ER0S EdgeBox for status and condition monitoring across large sites — long range, self-healing, no SIM and no base station.

  • Industrial — equipment condition & environmental status monitoring
  • Infrastructure — distributed environmental monitoring across sites
The Ecosystem

Everything the EdgeBox connects.

From lighting-control silicon to a 5G DECT NR+ stack and thermal sensing — all engineered around the same wireless core the ER0S bridges to your network.
