Key Features:

1. Cable Mapping: Interactive tool to create digital maps of cable layouts
2. Inventory Management: Track cable types, lengths, and connections
3. Smart Labeling: Generate and print labels for easy identification
4. Safety Alerts: Notify users of potential overloads or hazards
5. Integration Guide: Suggest optimal cable routing for new device installations
6. Maintenance Reminders: Schedule checks and replacements for aging cables

User Requirements:

• Easy-to-use mobile and web interfaces
• Secure cloud storage for cable layout data
• Compatibility with common smart home ecosystems (e.g., HomeKit, Google Home)
• Ability to share setups with other users or professionals

User Flows

1. New Setup Mapping:

   • User logs in > Selects "New Map" > Chooses room layout > Adds devices and cable connections > System generates optimized routing > User adjusts if needed > Saves and labels setup

2. Adding New Device:

   • User logs in > Selects existing map > Chooses "Add Device" > Enters device details > System suggests optimal cable routing > User confirms or adjusts > Updates inventory and generates new labels

3. Maintenance Check:

   • System sends reminder > User logs in > Reviews flagged items > Checks physical setup > Marks items as checked/replaced > System updates records and resets reminders

Design Rationale

The Smart Home Cable Management System is designed with scalability, user-friendliness, and integration in mind. React and React Native were chosen for their cross-platform capabilities and large ecosystem. Node.js provides a JavaScript-based backend for consistency across the stack. MongoDB offers flexibility for evolving data structures common in IoT environments. The modular architecture allows for easy addition of new features and integrations with various smart home ecosystems. Security is prioritized through JWT authentication and regular audits. The deployment strategy leverages cloud services for reliability and scalability, crucial for a system that may need to handle complex home setups and multiple users.
