NetDash

NetDash is a lightweight mobile network monitoring dashboard designed to run on a rooted Android device using Termux.

It exposes a local web dashboard accessible from devices on the same LAN, providing real-time and historical monitoring of cellular network metrics, device status, and command plugins.

The project is designed to be simple, efficient, and low resource, making it suitable for continuous execution on mobile hardware.

Architecture

ARCHITECTURE.md
NetDash follows a lightweight monitoring architecture optimized for mobile hardware:

Android system commands
        ↓
Python collectors (signal, cell, battery, hardware, hotspot, etc.)
        ↓
Scheduler / RAM cache / CSV history
        ↓
Flask API
        ↓
Web dashboard (Chart.js + Vanilla JS)
        ↓
Commands / Plugin panels (dynamic state)

Key design goals:

• minimal CPU usage
• minimal dependencies
• modular collectors
• simple frontend
