Oroboro Dashboard

A full-screen marine instrument dashboard for Signal K. Built for liveaboard sailors who want all critical data — wind, depth, speed, battery, solar, tanks — on one screen, readable from across the galley.

Features

• Wind rose with apparent and true wind angle/speed
• True wind calculated client-side from AWS + AWA + STW
• 10-minute true wind speed history graph
• Battery state of charge with charging mode badge
• AC loads, DC loads, solar production per panel array
• Shore power detection and inverter status
• Water tank levels in % and liters
• Victron Cerbo GX support via signalk-venus-plugin
• Single HTML file — no frameworks, no dependencies, no internet required
• Fully configurable via config.js

Requirements

• Signal K server (tested with 1.46.x and 2.x)
• For Victron data: signalk-venus-plugin connected to a Cerbo GX
• Any modern browser (Chrome, Chromium, Firefox, Safari)
• Raspberry Pi with Chromium in kiosk/fullscreen mode (recommended)

Installation

Quick start

1. Download dashboard.html and config.js
2. Edit config.js to match your boat
3. Open dashboard.html in your browser

On a Raspberry Pi (recommended)

cd ~ && wget https://raw.githubusercontent.com/fpugliano/oroboro-dashboard/main/dashboard.html
wget https://raw.githubusercontent.com/fpugliano/oroboro-dashboard/main/config.js

Edit config.js with your settings, then open in Chromium:

chromium-browser --start-fullscreen file:///home/pi/dashboard.html

Via Signal K App Store

Once published, install directly from the Signal K admin panel:

1. Go to http://localhost:3000
2. Click Appstore
3. Search for "oroboro-dashboard"
4. Click Install
5. Access at http://localhost:3000/@fpugliano/oroboro-dashboard

Auto-start on boot

mkdir -p ~/.config/autostart
cat > ~/.config/autostart/dashboard.desktop << 'EOF'
[Desktop Entry]
Type=Application
Name=Marine Dashboard
Exec=chromium-browser --start-fullscreen --noerrdialogs file:///home/pi/dashboard.html

Configuration

Edit config.js to set your Signal K server address, tank capacities, solar panel maximums, and battery/inverter instance IDs.

Find your instance IDs in the Signal K Data Browser under electrical.batteries.*, electrical.inverters.*, and electrical.solar.*.
