Abstract: The evolution towards smart living environments necessitates robust and user-centric control systems that transcend the limitations of traditional manual appliances. This paper presents the design and implementation of a centralized, dual-mode Internet of Things (IoT) system for intelligent home automation. The system provides seamless control over household devices through two distinct interfaces: a web-based application for remote monitoring and management, and a voice recognition module for hands-free operation. A key architectural feature is its dual-mode functionality, which ensures continuous operation by seamlessly switching between a cloud-based (online) mode for remote access and a local (offline) mode during internet outages. The hardware prototype is centered around an ESP32 microcontroller, which interfaces with sensors and relay modules, while a Firebase cloud backend synchronizes state with a React Native frontend. The successful implementation validates a reliable, convenient, and efficient solution that enhances user autonomy and bridges the gap between conventional home management and modern intelligent control systems. This work contributes a practical framework for developing resilient and accessible smart home technologies.
