How it is wired
Three pieces, one path for the data.
- 01 / On the pole
A controller on each luminaire
Fits a NEMA or Zhaga socket on any LED fixture, any manufacturer, from 100 to 527 V, with 0-10V or DALI dimming.
- 02 / In the field
A network that heals itself
Wi-SUN, RF mesh, LTE-M, NB-IoT or LoRaWAN, mixed in one deployment. Nodes keep their schedule if the link drops.
- 03 / In the office
One platform, one interface
Groups, schedules, dimming profiles, faults and reports. Work orders pushed straight into your existing asset system.
What your operator opens on Monday morning
Fault detection, energy per group and the night dimming profile, on one screen. Alarms become work orders in your own asset management system through the REST API.

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.
A controller node sits on each luminaire and reports its status, energy use and faults. A gateway relays that data to a management platform, where lighting groups, schedules and dimming profiles are set. The result is lower energy consumption, maintenance dispatched only where a fault actually exists, and an accurate, always-current inventory of the lighting network.
Proof at scale
Networks that already run on Dimonoff
These deployments already account for more than 219,500 connected endpoints, with tens of thousands more underway in phased rollouts like Columbus, Ohio. Every figure on their pages links to the public document that states it.

Montréal, Canada
Montréal converted its entire street lighting network to LED and connected every fixture to one management platform, across 19 boroughs and three different controller vendors.

Mississauga, Canada
Mississauga converted 50,000 street lights to LED and put a utility-accepted revenue meter inside every node, so adaptive dimming could be billed on measured consumption.

Laval, Canada
Laval converted 37,000 street lighting fixtures under a $34.5 million contract and connected the lighting platform to the asset management, traffic and GIS systems the City already ran.

Columbus, Ohio, United States
Columbus began converting its street lighting to Dimonoff's networked LED system in 2021, starting in the Linden neighbourhood. The City's full network runs to 58,000 lights, and conversion is proceeding in phases.

Shawinigan, Quebec, Canada
Shawinigan's aging high-pressure sodium streetlights had reached end of life. The City replaced its full cobra-head fleet, 6,141 fixtures, with a Dimonoff | SCMS network set to 60% output at launch, and later added sewer-level sensors to the same platform.

Ankeny, Iowa, United States
Karl Chevrolet, the third-largest Chevrolet dealership in the United States at 1,307,815 square feet, had been shutting off half its lighting after hours to control costs, creating uneven, unsecure lighting across the lot. It converted 316 fixtures to LED with Dimonoff RME nodes instead.

Québec City, Quebec, Canada
Galeries de la Capitale, Québec City's largest mall at 1,500,000 square feet, was running 30-year-old sodium fixtures with security and energy costs trending the wrong way. It converted about 200 fixtures to LED with Dimonoff RME nodes, linked to its building management system.

Dover, New Hampshire, United States
Dover's street lighting was owned and operated by a public utility, which meant the City had no visibility into consumption and no data to negotiate its own lighting bill. Converting 1,781 fixtures to LED with Dimonoff's wireless control system changed both.

Highland Park, Illinois, United States
Residents near Highland Park's outdoor arena had raised safety concerns about inadequate lighting in the surrounding commercial district. The City converted 130 fixtures to LED with Dimonoff RME nodes and Dimonoff | SCMS, in what it describes as the first smart lighting project on Chicago's North Shore.

Province of Quebec, Canada
Of Quebec's roughly 1,000 municipalities, only 10 exceed 100,000 residents, and most lack the budget to negotiate a smart lighting contract alone. The Fédération québécoise des municipalités coordinated group purchasing so smaller towns could convert at big-city pricing.

Varennes, Quebec, Canada
Varennes had already converted its streetlights to LED by 2019. In 2023 it partnered with Hilo, Hydro-Québec's demand-response subsidiary, to dim its roughly 900 streetlights to 50% overnight and further during winter peak-demand events.

Sterling Ranch, Colorado, United States
Sterling Ranch, a planned smart-home community exposed to Colorado's natural disasters, wanted to reach residents outdoors in an emergency without new infrastructure. Dimonoff and Siemens built CitySafe into the community's streetlight network.

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 90 to 525 Vac at 50/60 Hz, 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.
