  • Energy price (EUR/kWh)
• Responsive UI for desktop and mobile

Requirements

• Node.js 18+
• A go-e charger reachable in your local network

Setup

1. Install dependencies:

npm install

2. Configure charger and pricing in config.json:

• chargerHost - charger IP/host in your LAN
• energyPriceEurPerKwh - electricity price used for cost display
• requestTimeoutMs - API timeout for charger requests

3. Start the dashboard:

npm start

4. Open http://localhost:3000.

In-App Settings

Use the Settings button at the bottom of the dashboard to change:

• Charger IP/host
• Energy price (EUR/kWh)

These settings are saved to config.json via /api/settings, so they remain after restart.

HTTP API (internal UI backend)

The frontend uses these endpoints exposed by server.js:

• GET /api/status - normalized live charger status for UI cards and controls
• GET /api/settings - current runtime settings (charger_host, energy_price_eur_per_kwh)
• POST /api/settings - persist charger host and energy price to config.json
• POST /api/settings/charging - start/stop charging
• POST /api/settings/phases - set configured phases (1 or 3)
• POST /api/settings/current - set charging current (6|10|12|14|16)
