The rapid growth of the Internet of Things (IoT) has enabled the development of innovative smart home automation systems that enhance comfort, safety, and energy efficiency. Conventional systems often rely solely on cloud-based platforms or high-cost commercial solutions, which can limit accessibility and usability for common households. This paper presents an IoT-based smart home automation system that integrates Arduino microcontroller, ESP32, Adafruit IO cloud services, and Bluetooth-based voice assistance to provide a cost-effective and hybrid solution. The system is designed to control multiple household appliances including a tube light, bulb, and fan using relays, with dual modes of operation: cloud monitoring via ESP32 with Adafruit IO and local voice commands via HC-05 Bluetooth module connected to Android and iOS applications. The Adafruit IO platform enables real-time monitoring of device status with timestamp logging, ensuring transparency and energy usage tracking, while Bluetooth-based voice control enhances accessibility and usability for all age groups. The proposed system demonstrates efficient performance, low latency, and user-friendly interaction, making it suitable for smart homes, elderly care, and energy management applications.
