-📁 Key Files Created/Modified:
-  • data-ingestion-service/sa4cps_config.py - SA4CPS configuration
-  • data-ingestion-service/data_processor.py - Added .slg_v2 support  
-  • data-ingestion-service/startup_sa4cps.py - Auto-configuration script
-  • data-ingestion-service/models.py - Added SLG_V2 format
-  • docker-compose.yml - Added data-ingestion-service
-
-🔧 To Deploy and Run:
-
-1. Build and start the services:
-   cd microservices
-   docker-compose up -d data-ingestion-service
-
-2. Configure SA4CPS connection:
-   docker-compose exec data-ingestion-service python startup_sa4cps.py
-
-3. Monitor the service:
-   # Check health
-   curl http://localhost:8008/health
-   
-   # View data sources  
-   curl http://localhost:8008/sources
-   
-   # Check processing stats
-   curl http://localhost:8008/stats
-
-4. Manual FTP credentials (if needed):
-   # Update credentials via API
-   curl -X POST http://localhost:8008/sources/{source_id}/credentials \\
-        -H "Content-Type: application/json" \\
-        -d '{"username": "your_user", "password": "your_pass"}'
-
-📋 Environment Variables (in docker-compose.yml):
-  • FTP_SA4CPS_HOST=ftp.sa4cps.pt
-  • FTP_SA4CPS_USERNAME=anonymous  
-  • FTP_SA4CPS_PASSWORD=
-  • FTP_SA4CPS_REMOTE_PATH=/
-
-🔍 Features:
-  ✅ Monitors ftp.sa4cps.pt for .slg_v2 files
-  ✅ Processes multiple data formats (CSV, space-delimited, etc.)
-  ✅ Auto-detects headers and data columns
-  ✅ Intelligent unit inference
-  ✅ Publishes to Redis topics: sa4cps_energy_data, sa4cps_sensor_metrics, sa4cps_raw_data
-  ✅ Comprehensive error handling and monitoring
-  ✅ Duplicate file detection
-  ✅ Real-time processing status
