The system connects cloud or owner-controlled on-premises servers, CH-800 gateways, intelligent lighting cabinets, circuit controllers and SLC810/SLC910 lamp-level controllers. Hybrid OFDM PLC and LoRA communications support remote control and monitoring across complex feeders, long corridors and demanding electrical environments. Traffic and luminance sensors can support scheduled or adaptive dimming, while the platform provides asset views, alarms, energy records, operating reports and fault-location information. Adaptive CCT from 2700K to 6000K can be configured for project-specific rain, fog and snow conditions. Role-based access, traceable operation records, offline local operation and controlled recovery help owners maintain safe lighting when the central platform or communication network is unavailable. Interfaces and third-party integration are configured according to local regulations, owner requirements and project specifications.
