## 🚀 Quick Start

### Prerequisites
- Docker and Docker Compose
- Python 3.11+ (for local development)
- Node.js 18+ (for frontend development)

### Development Setup

1. **Clone the repository**
   ```bash
   git clone <repository-url>
   cd energy-tracking

2. Start the development environment

   docker-compose -f docker-compose.dev.yml up -d

3. Access the services

   • Frontend Dashboard: http://localhost:3000 (Main application interface)
   • API Gateway: http://localhost:8000 (Central API endpoint)
   • API Documentation: http://localhost:8000/docs (Interactive Swagger UI)
   • Authentication Service: http://localhost:8005 (User management)
   • Grafana Monitoring: http://localhost:3001 (admin/admin)
   • InfluxDB Interface: http://localhost:8086 (Time-series database)
   • IoT Mock Service: http://localhost:8090 (Device simulation)
   • Nginx Proxy: http://localhost:8080 (Load balancer)

4. Start IoT device simulation

   # Using the IoT Mock Service
   curl -X POST http://localhost:8090/api/v1/simulation/start
   
   # Check device data
   curl http://localhost:8090/api/v1/devices

1. Configure environment variables

   cp .env.example .env
   # Edit .env with your production settings

2. Deploy with Docker Compose

   docker-compose -f docker-compose.prod.yml up -d

1. Authentication: Users authenticate with JWT tokens and role-based permissions
2. Data Ingestion: IoT devices send data via MQTT or HTTP APIs (with proper authorization)
3. Data Processing: Real-time validation, transformation, and enrichment
4. Access Control: Role-based filtering ensures users only see authorized data
5. Storage: Time-series data stored in InfluxDB, metadata in PostgreSQL
6. Analytics: Background processing for forecasting and analysis (permission-based)
7. Visualization: Real-time dashboard updates via WebSockets with user context
8. Audit: All user activities and data changes are logged for compliance
