+# Service Adapters
+
+Python FastAPI service for integrating with external homelab services.
+
+## Purpose
+- Integrate with Home Assistant, Frigate, Immich, n8n
+- Transform external service data into standardized format
+- Publish events to the message bus
+- Provide unified API for service data
+
+## Technology Stack
+- **Language**: Python 3.11
+- **Framework**: FastAPI
+- **Port**: 8000
+- **Message Bus**: Redis
+
+## Features
+- Home Assistant entity integration
+- Frigate event processing
+- Immich asset management
+- n8n workflow triggers
+- Event publishing to Redis
+
+## Development Status
+✅ **Complete** - Core functionality implemented
