This project presents a groundbreaking paradigm shift in residential energy management and automation, offering an innovative solution that seamlessly integrates two diverse energy sources: solar and conventional grid (EB) power. With solar energy taking precedence as the primary power supply, meticulously controlled by the versatile ESP32 microcontroller, the system ensures a consistent and reliable energy supply by intelligently switching to grid power when solar resources are scarce, seamlessly reverting back to solar power as soon as it becomes available again. In addition to its dynamic energy management capabilities, the project incorporates an LCD screen to provide homeowners with real-time insights into their energy consumption patterns, offering a comprehensive overview of usage data from both energy sources. This invaluable information empowers users to make informed decisions about their energy usage habits, fostering a more conscious and efficient approach to power consumption. Furthermore, the integration of the Blynk 2.0 IoT platform elevates the project to new heights by enabling remote monitoring and control of the system. Through this intuitive interface, users can effortlessly manage their energy usage from anywhere using their smart phones or computers, ensuring maximum flexibility and convenience. Expanding beyond traditional energy management, the project delves into the realm of home automation with the incorporation of an additional ESP32 microcontroller. This feature-rich functionality empowers users to remotely control lighting fixtures, enhance safety measures with gas detection capabilities utilizing MQ2 sensors, and efficiently monitor water levels using ultrasonic sensors, all seamlessly integrated into the IoT eco system. This holistic solution not only prioritizes renewable energy sources and automates power source transitions but also leverages the transformative potential of IoT technology to create a sustainable and intelligent approach to energy management. Powered by ESP32 technology, this project serves as a trailblazer for the future of smart, efficient, and eco-friendly homes, setting a new standard for residential energy management and automation.
