Modern demands for increased energy efficiency and automation in living spaces have driven the development of smart electrical installations that are gradually replacing traditional systems. Smart installations enable automation, remote control, and better monitoring of energy consumption, significantly improving user comfort and safety. The purpose of this thesis was to explore modern technologies in the field of smart electrical installations, with a focus on the Shelly system, and to develop an educational demonstration model based on this technology. The theoretical part presents the basic concepts of low-voltage installations, protective components, an overview of communication protocols (KNX, Zigbee, Modbus, Wi-Fi), and the differences between traditional and smart installations. In the practical part, an educational demonstration model was designed and constructed in the form of a panel that represents the layout of a studio apartment. It includes Shelly system devices that enable control of lighting, ventilation, shading, and flood detection. The main emphasis is placed on the configuration and programming of scenarios in the Shelly software environment, while the electrical connections are prepared in advance, allowing focused execution of the practical exercise. The use of the Shelly system proved to be very suitable for educational purposes, as it combines accessibility, reliability, and functional flexibility.
