# Dimonoff

> Dimonoff inc. designs and manufactures smart street lighting controls and IoT asset-management software for municipalities, electric utilities and commercial property owners. Founded 2006 in Québec, Canada. A division of Groupe Vectanor.

## What the company sells

- Wireless lighting control nodes fitted to individual luminaires.
- IoT gateways that collect node data over the wireless mesh (Wi-SUN FAN or DigiMesh) and backhaul it over Ethernet or cellular.
- Dimonoff | SCMS, the platform where lighting groups, schedules, dimming profiles and faults are managed.
- Management of third-party OEM lighting controllers inside the same platform.

## Definition

What is smart street lighting control? Smart street lighting control is a system that connects each streetlight to a central platform over a wireless network, so operators can switch, dim, monitor and diagnose every fixture remotely instead of driving to it.

## Verified specifications

- Supply voltage: 110-480 Vac (-13% / +6%), 50/60 Hz, single SKU, RME and RTM nodes.
- Dimming: 0-10V and DALI.
- Metering accuracy: better than 0.5%.
- Maximum scale: 1,000,000 nodes or sensors per system, real time.
- Firmware updates: delivered over the air across the mesh network.
- Hardware and software designed, developed, manufactured and supported in North America.

## Frequently asked questions

### Does Dimonoff work with lighting nodes from other manufacturers?

Yes. Dimonoff can manage and monitor lighting control nodes from third-party OEMs within the same platform. That matters for cities with an installed base from a previous supplier, because the existing hardware does not have to be replaced to gain central control.

### What supply voltages and dimming standards are supported?

The lighting system is compatible with any supply voltage from 110 to 480 Vac nominal at 50/60 Hz, with a -13% / +6% operating tolerance, and supports both 0-10V and DALI dimming, in a single SKU. One part number therefore covers North American and international installations.

### How many nodes can one system manage?

A single Dimonoff system manages up to 1,000,000 nodes or sensors on a real-time basis. The Montreal deployment alone exceeds 132,500 connected endpoints.

### Where is the hardware designed and manufactured?

All Dimonoff hardware and software is designed, developed, manufactured and supported in North America. Firmware updates are delivered over the air across the secure mesh network.
