Real-time Telemetry:
Monitoring Poland's
Hydro-Meteo Data.
We designed and developed a dedicated web application for visualizing and archiving telemetry data. The system aggregates real-time measurements from scattered stations (Hydro/Meteo) onto a single interactive map, providing historical analysis and a robust admin panel for technical monitoring of the infrastructure. Ready to dive deep into the details? Let's go.
The client needed a centralized platform to manage a growing network of telemetry stations. The goal was twofold: allow authorized users to easily check current weather and water conditions via an interactive map, and give administrators a powerful tool to monitor the "health" of the stations (battery voltage, door status, solar panel efficiency) without visiting them physically.
A major strength of Silentbits is their deep technical expertise and ability to translate complex challenges into business-oriented solutions. The system operates reliably, is fast, and very well designed from a user experience perspective.
The Challenge.
Complex Data Synchronization
The client faced data gaps due to unstable GSM connectivity. Standard "last hour" fetching was insufficient because stations often buffered data offline during outages and sent it hours later ("Store and Forward" mode).
Critical Incident Response
Rapid reaction to exceeding alarm thresholds (e.g., river flooding) was required, but the system had to be immune to false alarms caused by temporary sensor glitches.
Data Clarity vs. Density
Displaying different units (e.g., rainfall in mm vs. water level in cm) on a single screen risked creating visual chaos, hindering quick IMGW-style analysis.
Performance & Scale
Aggregating thousands of measurement points from diverse sources and visualizing them on charts without slowing down the user interface.
Hardware Monitoring
Transforming raw technical logs into clear, actionable alerts for the maintenance crew to prevent hardware failures.
The Solution.
Interactive Dashboard
We built the core using Next.js for a fast and responsive frontend. The heart of the system is an interactive map where clicking a station reveals instant data and customizable charts (24h/7d/30d/All).
Automated SMS Alerting Engine
We designed a reliable backend state machine integrated with an external SMS API. Administrators gained a panel to independently configure warning and alarm thresholds, while the system automatically filters data noise, dispatching alerts only during real threats.
Industrial-Grade Analytics
We implemented advanced dual-axis charts to seamlessly compare different measurement units. Users can interactively zoom in on data and access a comprehensive statistics panel (trends, absolute min/max with dates, zero elevation) modeled after professional meteorological standards.
48h Micro-Detail View & History
We expanded the UI to include a detailed 48-hour preview chart triggered by clicking any specific measurement tile, alongside a structured historical data table (06 UTC / full hours views) for deep-dive analysis.
Smart "Watermark" Scheduler
Instead of simple periodic fetching, we implemented a dynamic synchronization algorithm. The backend remembers the timestamp of the last successful record for each station and automatically "backfills" any missing history once the connection is restored. This ensures 0% data loss and makes the system self-healing without manual admin intervention.
