CoreSync Examples

FROST + Influx + Grafana

Import frost-influx-grafana.flow.json into Node-RED when the local Docker stack is running.

The flow demonstrates:

• a measurement node producing a 1 Hz directional flow signal;
• a rotatingMachine node producing event-driven pump telemetry;
• raw EVOLV telemetry written to local InfluxDB;
• CoreSync reducing the same telemetry to knots;
• CoreSync FROST HTTP requests sent to https://sta.wbd-rd.nl/FROST-Server/v1.1;
• FROST responses looped back into CoreSync as msg.topic = "frost.response";
• CoreSync knots also written to local InfluxDB as coresync_knots for Grafana comparison.
• a Node-RED dashboard page with live raw-field, knot, FROST observation, and percent-saved counters.

Do not store FROST credentials in the flow. Start Node-RED with:

FROST_USER=write FROST_PASSWORD='<password>' docker compose up -d --build

The local InfluxDB and Grafana settings match docker-compose.yml:

• InfluxDB: http://localhost:8086, org evolv, bucket telemetry, token evolv-dev-token
• Grafana: http://localhost:3000, user admin, password evolv

The provisioned Grafana dashboard CoreSync FROST Demo compares raw telemetry against the reduced knot stream. The raw samples are intentionally denser than the knot series; the knot series is the data that should be sent to FROST.

Runtime dashboards:

• Node-RED live counters: http://localhost:1880/dashboard/coresync-frost
• Grafana raw-vs-knot comparison: http://localhost:3000/d/coresync-frost-demo/coresync-frost-demo
