 The Calejo Control Adapter translates optimized pump control plans from Calejo Optimize into real-time control signals for municipal wastewater pump stations. It supports diverse SCADA systems with minimal configuration through automatic discovery and multiple protocol support.
 
+### Implementation Status
+
+✅ **Phase 1**: Core Infrastructure
+- Database connection pooling with FlexibleDatabaseClient
+- Auto-discovery of pump stations and pumps
+- Safety framework with limit enforcement
+- Emergency stop management
+- Optimization plan management
+
+✅ **Phase 2**: Multi-Protocol Servers
+- OPC UA server implementation
+- Modbus TCP server implementation
+- REST API server implementation
+- Database watchdog for failsafe operation
+- Alert management system
+
+✅ **Phase 3**: Setpoint Management
+- Setpoint Manager for real-time control
+- Integration with all safety components
+- Unified main application
+
+All components are implemented and tested with 133 passing tests.
+
 ### Key Features
 
 - **Multi-Protocol Support**: OPC UA, Modbus TCP, and REST API simultaneously
