It functions as an automated shutdown coordinator and a network power monitor, implementing the RFC 9271 standard for communicating with power hardware. The project acts as a hardware driver translation layer, converting signals from USB, serial, and SNMP interfaces into a unified data format. It employs a client-server architecture to stream battery and voltage metrics from hardware drivers to remote monitoring clients across a network. Capabilities include real-time power monitoring, hardware status visualization via web-based dashboards, and the management of power distribution units. The system also handles automated safe shutdowns based on critical battery thresholds and provides tools for device discovery and hardware reset recovery. Security is managed through IP-based access control for server commands and the assignment of hardware access privileges via system rules. ## Tags ### Software Engineering & Architecture - [Power-Down Sequences](https://awesome-repositories.com/f/software-engineering-architecture/event-driven-logic/power-down-sequences.md) — Triggers system power-down sequences based on specific hardware events and critical battery thresholds. - [Client-Server Architecture](https://awesome-repositories.com/f/software-engineering-architecture/client-server-architecture.md) — Employs a centralized server to manage hardware state and stream that state to multiple remote monitoring clients. - [Request-Response Interfaces](https://awesome-repositories.com/f/software-engineering-architecture/request-response-interfaces.md) — Processes standardized control commands and status queries between remote clients and the management server. ### System Administration & Monitoring - [Automated Shutdown Coordinators](https://awesome-repositories.com/f/system-administration-monitoring/automated-shutdown-coordinators.md) — Triggers safe operating system power-downs when battery thresholds reach critical levels to prevent data loss. - [Hardware Health Monitoring](https://awesome-repositories.com/f/system-administration-monitoring/hardware-health-monitoring.md) — Provides tracking of physical hardware metrics such as battery health, voltage, and runtime for uninterruptible power supplies.
