Highlights

Serial sensor ingestion to SQLite with graceful shutdown
Optional web dashboard with live charts and time-range controls
Weather overlays via OpenMeteo plus CSV export and Docker deployment

Overview

Skogsnet v2 reads temperature and humidity from a serial-connected sensor, stores them in SQLite, and can serve a web dashboard with live charts and weather overlays pulled from OpenMeteo.

Skogsnet v2 dashboard — Live dashboard with temperature, humidity, and weather overlays.

Problem / approach

Collect and persist sensor data reliably from a serial device.
Provide live visualization with time-range controls and dark mode.
Offer simple deployment with optional Docker and CSV export.

Solution

Go service that ingests JSON measurements over serial, logs to SQLite, and handles graceful shutdown.
CLI flags for baud rate, port, dashboard, logging, weather fetch, and CSV export.
Optional Node-built dashboard served at http://localhost:8080 with interactive charts and live updates.
Docker Compose configuration plus host-mounted volumes for DB and logs.

Outcome

End-to-end pipeline from sensor to persisted data to browser dashboard.
Flexible runtime modes: headless logging, logging + weather, or full dashboard.
Testable with go test ./internal and ready for containerized deployment.
