A Prometheus exporter for the Odroid Smart Power 3, written in Go. This exporter reads real-time power metrics from the OSP3 via a USB serial connection and exposes them for Prometheus scraping.
- Real-time Monitoring: Tracks voltage, current, power, and channel status.
- Multi-Channel Support: Reports metrics for
input,channel 0, andchannel 1. - Flexible Configuration: Use command-line flags or environment variables.
- Docker Ready: Includes a multi-arch Dockerfile for easy deployment.
- Auto-Reconnect: Automatically attempts to reconnect if the serial connection is lost.
