Design Rationale

The smart gazebo controller is designed with modularity and scalability in mind. The use of a Raspberry Pi as the central control unit provides a balance of power and flexibility. The choice of Node.js for the backend allows for efficient handling of concurrent connections, crucial for IoT applications. React Native is selected for the mobile app to ensure a consistent user experience across both iOS and Android platforms. The MQTT protocol is employed for its lightweight nature, making it ideal for IoT device communication. AWS IoT Core is chosen for its robust security features and seamless integration with other AWS services, providing a solid foundation for future expansion of the smart home ecosystem.
