One of the key directions in modern manufacturing development is the creation of so-called “smart” devices, which form the basis of cutting-edge Industry 4.0 and 5.0 concepts. These new approaches have emerged as a result of the evolving Internet of Things (IoT) technology, which connects physical objects equipped with sensors, microcontrollers, and software to collect data and control devices. Integrating smart devices into everyday life and production enables the automation of routine tasks, leading to significant cost and energy reductions, thus promoting sustainable development and economic growth. The primary IoT application areas span diverse sectors, including industry, smart cities, agriculture, and logistics. A critical direction in IoT development is designing an optimal system architecture that enhances security, scalability, and resilience. Effective architectures should incorporate encryption and authentication to protect sensitive data, ensure seamless integration of new devices, and maintain reliability in critical conditions, particularly during unexpected power outages. This study focuses on developing an optimal IoT system architecture and software implementation for device management using the ESP32 platform, addressing tasks such as designing an automatic lighting control system and implementing control software. The project involves IoT devices like the ESP-WROOM-32 microcontroller, electromechanical relays, LED lamps, a voltage detector with an optocoupler, a boost converter, Schottky diodes, and a capacitor. An algorithm for system state determination using electromechanical relays and a voltage detector is proposed. The system’s resilience in case of sudden power loss is demonstrated.
