PeaNUT: A Tiny Dashboard for Network UPS Tools

Introduction

PeaNUT is an open-source, lightweight dashboard designed to provide a user-friendly interface for monitoring Uninterruptible Power Supply (UPS) devices connected via Network UPS Tools (NUT). It allows users to view real-time statistics, status updates, and manage their UPS devices efficiently. Built with TypeScript and Next.js, PeaNUT offers a modern and responsive experience for keeping an eye on your power infrastructure.

Installation

PeaNUT provides flexible installation options, primarily leveraging Docker for ease of deployment.

Using Docker

You can run PeaNUT directly with docker run or integrate it into your docker-compose.yml setup.

`docker run`

docker run -v ${PWD}/config:/config -p 8080:8080 --restart unless-stopped \
--env WEB_PORT=8080 brandawg93/peanut

`docker-compose.yml`

services:
  peanut:
    image: brandawg93/peanut:latest
    container_name: PeaNUT
    restart: unless-stopped
    volumes:
      - /path/to/config:/config
    ports:
      - 8080:8080
    environment:
      - WEB_PORT=8080

Compile from Source

For those who prefer to build from source, PeaNUT can be compiled using pnpm.

git clone https://github.com/Brandawg93/PeaNUT.git
cd PeaNUT
npm i -g pnpm # only if you don't have pnpm installed
pnpm i
pnpm run build:local
pnpm run start:local

PeaNUT supports linux/amd64 and linux/arm64 platforms, making it suitable for devices like Raspberry Pi 4+.

Examples

PeaNUT is designed for integration and offers various ways to display and interact with your UPS data.

Homepage Support

PeaNUT integrates seamlessly with Homepage, allowing you to display UPS metrics directly on your dashboard.

widget:
  type: peanut
  url: http://peanut.host.or.ip:port
  key: nameofyourups

More advanced customization is possible using the customapi widget.

Glance Support

You can also integrate PeaNUT with Glance for a detailed overview of your UPS status.
