VoltGrid ingests sensor telemetry through every standard smart-grid protocol — OGC SensorThings, OGC SOS, MQTT, Kafka, Esri StreamServer emulation, HTTP poll, SSE, and WebSocket — and joins it with structures, conductors, and vehicles in one scene. Watch fault-indicator trips, weather stations, line tension monitors, and SCADA overlays update live against the corridor.
All eight transports below are implemented as real feed adapters — verified in Src/LocalMapServer/. Each lands observations in the unified Feeds subsystem with the same analytics, replay, and AAR tooling as vehicle tracks.
| Protocol | Best for | Adapter |
|---|---|---|
| OGC SensorThings API | Multi-thing IoT networks (weather, fault indicators) | Feeds/SensorThingsFeedAdapter.cs |
| OGC SOS (Sensor Observation Service) | Legacy sensor networks, hydromet stations | Feeds/SosFeedAdapter.cs |
| MQTT | Lightweight publish/subscribe telemetry bus | Osint/CustomFeeds/MqttOsintTransport.cs |
| Kafka | High-throughput enterprise telemetry pipelines | Osint/CustomFeeds/KafkaOsintTransport.cs |
| Esri StreamServer emulation | Push sensor streams to ArcGIS clients | Src/LocalMapServer/Stream/ |
| HTTP poll | REST sensor endpoints without push | Osint/CustomFeeds/HttpPollOsintTransport.cs |
| Server-Sent Events (SSE) | One-way streaming REST endpoints | Osint/CustomFeeds/SseOsintTransport.cs |
| WebSocket | Bi-directional streaming sensor connections | Osint/CustomFeeds/WebSocketOsintTransport.cs |
All listed transports are shipping code — JSON-path field mapping (JsonPathMapper) normalizes each vendor's payload shape.
Bring SCADA-tag values into VoltGrid via the gateway's MQTT / Kafka bus — line loading, breaker status, transformer temperatures next to the assets they describe.
Weather stations, fire-weather indices, and wind/gust sensors along the corridor — feed the IEEE 738 thermal model with real conditions.
Locate faults faster — fault-indicator trips drop straight onto the affected span with the time stamp the dispatcher needs.
Conductor tension monitors and dynamic line rating (DLR) sensors feed sag-tension analyses with real-time values.
Satellite + LiDAR encroachment alerts and tree-fall sensors — direct to NERC FAC-003 findings.
Wildfire cameras, asset-health monitors, and acoustic / partial-discharge sensors for predictive maintenance.
VoltGrid reaches SCADA systems today through the gateway's MQTT / Kafka bus — that's how most modern utilities bridge OT to IT. For sites that need direct protocol-native ingestion, these adapters are on the roadmap.
TCP / RTU; widely deployed in legacy substation IEDs.
Modern industrial interoperability standard.
Telecontrol equipment & systems (Europe / Asia).
Substation communications, GOOSE / SV / MMS.
North-American utility SCADA standard.
IoT platform; today via MQTT integration.
Edge stream processing; today via Kafka bridge.
GPS tracking platform; today via MQTT / webhook.
Today's path: SCADA → MQTT/Kafka gateway → VoltGrid. Most utilities already run this bridge for OT/IT segmentation, so the integration is one broker hop away.
Sensor events alongside vehicle positions and structure data give operations a complete real-time picture of the grid.
