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. Each lands observations in the unified Feeds subsystem with the same analytics, replay, and AAR tooling as vehicle tracks.
| Protocol | Best for | Integration Method |
|---|---|---|
| OGC SensorThings API | Multi-thing IoT networks (weather, fault indicators) | SensorThings REST / MQTT |
| OGC SOS (Sensor Observation Service) | Legacy sensor networks, hydromet stations | OGC SOS 2.0 XML Adapter |
| MQTT | Lightweight publish/subscribe telemetry bus | MQTT 3.1.1 / 5.0 Subscriber |
| Kafka | High-throughput enterprise telemetry pipelines | Kafka Consumer Transport |
| Esri StreamServer emulation | Push sensor streams to ArcGIS clients | ArcGIS WebSocket StreamServer |
| HTTP poll | REST sensor endpoints without push | Configurable HTTP Poller |
| Server-Sent Events (SSE) | One-way streaming REST endpoints | SSE Stream Consumer |
| WebSocket | Bi-directional streaming sensor connections | Bi-directional WebSocket Client |
All listed transports feature automated JSON-path field mapping to normalize varying vendor payload schemas.
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.
For a live outage + telemetry overlay today, use the shipping OMS / SCADA overlay (HTTP GeoJSON/CSV push or poll). VoltGrid also reaches SCADA tag values through the gateway's MQTT / Kafka bus. Direct protocol-native adapters below remain on the roadmap for sites that need them.
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.
