PeaNUT is a lightweight web dashboard for monitoring UPS devices through a Network UPS Tools (NUT) server. It provides a clean UI for live status and statistics, plus an HTTP API for integrations and automation.
Key Features
- Monitor one or multiple UPS devices exposed by a NUT server
- Real-time device statistics and status display
- Execute supported NUT commands and change writable variables
- Configurable via web UI with optional YAML-based configuration
- Built-in REST API endpoints for device data, commands, and health checks
- Prometheus metrics endpoint for monitoring and alerting
- Optional InfluxDB v2 integration for time-series dashboards (for example with Grafana)
- WebSocket terminal-style access for direct communication with the NUT server
- Optional Basic Authentication for UI and API access
Use Cases
- Homelab dashboard to track battery charge, runtime, load, and UPS state
- Integrate UPS status into monitoring/alerting systems via Prometheus
- Centralize visibility of multiple UPS devices across a network
PeaNUT is well-suited for users who already run NUT and want a modern, minimal web UI plus integration-friendly endpoints. It focuses on UPS visibility and control while remaining lightweight and easy to deploy.
