The Internet of Things (IoT) has transformed the way we interact with everyday objects, enabling seamless communication between devices and creating a more connected and intelligent environment. Home automation, a prominent application of IoT, offers the promise of enhanced comfort, energy efficiency, and security within the home. This research paper explores the design, development, and evaluation of an IoT-based home automation system controlled through an Android app. The primary objective of this study is to create a user-friendly and efficient Android application that acts as a centralized control hub for various smart home devices. The application leverages the ubiquity and capabilities of Android devices to provide homeowners with convenient and intuitive control over a range of IoT-enabled appliances, including lighting systems, thermostats, door locks, security cameras, and entertainment devices. To achieve this objective, a mixed-method approach is adopted. Initially, a thorough review of existing literature is conducted to establish the current state-of-the-art in IoT home automation and Android app development. The system architecture is designed, incorporating popular IoT communication protocols to facilitate seamless communication between the Android app and the IoT devices. The implementation phase follows established best practices and development frameworks to ensure a robust and reliable Android application. Furthermore, the research evaluates the performance, efficiency, and security aspects of the Android-based IoT home automation system. The findings of this research indicate that the Android-based IoT home automation system offers a user-friendly and efficient solution for smart living. Homeowners can remotely control and monitor their smart devices, leading to enhanced comfort and energy savings. The proposed system's security measures help safeguard against unauthorized access and protect sensitive user data. In conclusion, this research contributes to the advancement of IoT-based home automation, demonstrating the potential of Android devices as a versatile and accessible control interface.
