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. ## Proof points - 575+ Projects deployed - 500+ Cities served - 6 Countries - 20 yrs Platform in production ## Key differentiators - Asset monitoring at the speed of light: Metering accuracy better than 0.5%. - Third-party node management: In production in Montréal across three controller vendors. - One SKU, any network: 90-525 Vac, 50/60 Hz, 0-10V and DALI. - Lighting and sensors on one interface: One unified operator interface. - Built for the size you grow into: Up to 1,000,000 nodes per system. - Updates without a truck roll: Over-the-air updates across the mesh. ## Cooperative purchasing Dimonoff holds Sourcewell contract #041525-DIMN for smart lighting and control systems, valid through 2029-07-22.
