This research article presents the development and analysis of an IoT-enabled smart home automation system aimed at enhancing energy efficiency. The proposed system integrates various sensors, a Raspberry Pi as a central controller, and utilizes the Message Queuing Telemetry Transport (MQTT) protocol for efficient data transmission. The system architecture comprises multiple layers, including the device layer, broker layer, service layer, application layer, and cloud layer, each serving specific functions such as sensor data collection, communication, data management, and user interface. Real-time monitoring and control are facilitated through the application layer, which enables users to interact with the system using Node-Red Authentication. The system demonstrates fast response times of less than 15 ms, ensuring prompt and accurate actions in controlling home appliances. Moreover, the system effectively reduces energy consumption by optimizing the operation of appliances based on sensor inputs and user preferences. The proposed system showcases significant energy savings compared to manual systems, with power consumption reduced by up to 40%. The results indicate that the system achieves efficient energy management and contributes to cost savings for homeowners. Additionally, the system's user-friendly interface and real-time monitoring capabilities enhance the overall user experience. The research findings emphasize the potential of the proposed system in promoting energy-efficient practices in smart homes. Further advancements and research in this area can lead to more intelligent and sustainable home automation systems, ultimately benefiting both homeowners and the environment.
