It detects anomalies by comparing with historical patterns and automatically triggers alerts and follow-up actions when thresholds are exceeded.\n\n## Setup Steps\n1. **Configure Webhook Endpoint** - Set up webhook to receive data from wearable devices\n2. **Connect Database** - Initialize storage for health metrics and historical data\n3. **Set Normalization Rules** - Define data standardization parameters for different devices\n4. **Configure AI Model** - Set up health score calculation and risk prediction algorithms\n5. **Define Thresholds** - Establish alert triggers for critical health metrics\n6. **Connect Notification Channels** - Configure email and Slack integrations\n7. **Set Up Reporting** - Create automated report templates and schedules\n8. **Test Workflow** - Run end-to-end tests with sample health data\n\n## Workflow Template\nWebhook \u2192 Store Database \u2192 Normalize Data \u2192 Calculate Health Score \u2192 Analyze Metrics \u2192 Compare Previous \u2192 Check Threshold \u2192 Generate Reports/Alerts \u2192 Email/Slack \u2192 Schedule Follow-up\n\n\n"
