Integrating IoT for Smart Home Automation: Enhancing Energy Efficiency, Security, and System Optimization

The low-cost, Internet of Things-based home automation system presented in this study is intended to help the elderly and those with disabilities. Wireless control of home appliances, including fans, lights, heating, cooling, and security systems, is made possible by the system’s use of the Node MCU microcontroller with integrated Wi-Fi. Users can remotely operate devices via the internet with ease thanks to an easy-to-use Android app. The technology reduces the requirement for continual human intervention by supporting both manual control and autonomous operation depending on environmental variables. The system is incredibly accessible and practical because it can be accessed from any location thanks to a cloud-based server. To guarantee seamless control, many devices communicate with the Node MCU using various transmission modalities. This smart home solution is simple to install and use, and it enhances comfort, safety, and convenience. The Android platform offers real-time appliance status updates. All things considered, the project provides a scalable, effective, and user-friendly method of modern home automation that improves quality of life, particularly for the elderly and people with disabilities.
