User Requirements:

• Intuitive interface for managing devices and viewing data
• Mobile-responsive design for access on various devices
• Secure data transmission and storage
• Customizable alerts and notifications
• Ability to control devices remotely
• Access to historical data and analytics

User Flows

1. Device Registration: User logs in → Navigates to "Add Device" → Enters device details → Confirms registration → Device appears in dashboard

2. Alert Setup: User selects a device → Chooses "Set Alert" → Defines alert conditions → Sets notification preferences → Saves alert

3. Remote Control: User selects a device → Views current status → Chooses control action → Confirms action → Receives confirmation of execution

Technical Specifications

Frontend:

• React for building the user interface
• Redux for state management
• Chart.js for data visualization
• Axios for API requests

Backend:

• Node.js with Express.js for the server

Deployment Strategy

1. Containerize application using Docker
2. Set up a Kubernetes cluster for orchestration
3. Use a cloud provider (e.g., AWS, Google Cloud) for hosting
4. Implement a CI/CD pipeline using Jenkins or GitLab CI
5. Use Terraform for infrastructure as code
6. Set up monitoring with Prometheus and Grafana
7. Implement automated backups for databases
8. Use a CDN for static asset delivery
9. Implement SSL/TLS encryption
10. Set up log aggregation and analysis

Design Rationale

• React was chosen for its component-based architecture and large ecosystem
• Node.js provides a JavaScript-based backend for consistency with the frontend
• MQTT is ideal for IoT applications due to its lightweight nature and pub/sub model
• InfluxDB is optimized for time-series data, making it perfect for IoT sensor data
• The microservices architecture allows for better scalability and maintainability
• Docker and Kubernetes provide flexibility in deployment and scaling
• The chosen file structure separates concerns and promotes modularity
• The implementation plan prioritizes core functionality before moving to advanced features
• The deployment strategy focuses on scalability, security, and ease of management
