Features List

I. Comprehensive Power Monitoring • AC Input Monitoring • Input Voltage ( continuously measured • Input Current (A) – monitored and reported • Input Power (W) – calculated and displayed • AC Power State – presence/absence detection • DC Output Monitoring • Output Voltage (V) – monitored at UPS to Raspberry Pi • Output Current (A) – tracked for load demand • Output Power (W) – calculated and reported • Brownout/Undervoltage Alerts – triggers if below safe thresholds • Battery Monitoring • Pack Voltage (V) – live reporting • Charge/Discharge Current (A) – direction and magnitude • Remaining Capacity (%) – via calibration table or fuel gauge • Bank Support – one or two batteries, with automatic detection

⸻

II. LED Battery Visualization • Always-Visible LED Chart • 4 rows displayed at all times for consistency • Bright LED = active, Dim LED = inactive • Capacity Mapping Table • 76–100% → 4 LEDs lit • 51–75% → 3 LEDs lit • 26–50% → 2 LEDs lit • 5–25% → 1 LED lit • <5% → Critical Warning (blinking or highlighted) • Quick Reference Status • GOOD – system on AC, battery healthy • CHARGING – battery charging from AC • DISCHARGING – running on battery • CRITICAL – low battery state, shutdown imminent • UNKNOWN – no battery detected or invalid state

⸻

III. Advanced Analytics • Runtime Estimation • Calculates estimated minutes of operation under load • Uses load averages and calibrated discharge profiles • Power Smoothing • Exponential moving averages for stable real-time readings • Calibration Profiles • Voltage-to-percentage mapping by chemistry (per bank) • Guided calibration routine for full charge/discharge

⸻

IV. Event Logging & Diagnostics • System Log Capture • journalctl (current and previous boots) • dmesg (kernel buffer) • /var/log/syslog tail • UPS Event Logs • AC ↔ DC transitions • Low battery warnings • Undervoltage detections • Diagnostic Snapshots • JSON export of live sensor data for reporting and GitHub issues • Boot splash/plymouth log integration (optional)

⸻

V. Reliability & Safety Protocols • Secure Command Execution • All hardware/system commands require sudo • UUID/device verification required before formatting • Data Protection • rsync --dry-run enforced before copy/move operations • System Integrity • Automatic regeneration of GRUB after partition changes • Documentation update triggers alongside system updates

⸻

VI. Integration & Extensibility • Cross-Platform Compatibility • Raspberry Pi OS, Ubuntu, MX Linux, and future distributions • Data Sharing • Unified /mnt/data partition structure for documents/configs across OSes • Service Integration • Optional systemd service for 24/7 monitoring • Scalability • Ready for GUI extensions (tray widgets, panels) • Future Docker/Kubernetes integration for sandboxed deployments

⸻

VII. Documentation & User Experience • Embedded Legends • ANSI color chart and LED thresholds always displayed in UI • Professional Documentation • Full README with screenshots, calibration guides, and troubleshooting steps • Open Roadmap • Transparent roadmap and contribution guidelines
