Project Overview We are building an analytics module for an industrial tracking system (SINTRA). The system tracks assets (e.g. pallets) using smartphone-based 3D positioning (X, Y, Z). We already collect high-frequency data (time-series in InfluxDB). Goal: Build a Stability Analysis Dashboard to evaluate: data quality tracking stability device & zone performance detection issues ⚠️ Important Architecture (Must Follow) This project has a strict split: Backend / ETL (YOU BUILD) all calculations (jitter, jumps, gaps) scoring (0–100) classification (GREEN / YELLOW / RED) aggregations (1 min, 5 min, etc.) Grafana (YOU BUILD) dashboards charts tables filters alerts ❗ No business logic in Grafana ScopeETL / Backend process time-series data (x, y, z, timestamp) calculate: jitt...
