The implementation of energy-saving solutions becomes increasingly crucial as global energy reserves decline. The integration of automated solar shading systems not only improves living conditions, but also reduces energy costs. This work presents the design and implementation of an Internet of Things (IoT) automatic solar shading system. The developed solar shading includes custom-made louvers that are able to reflect the external light, while being transparent. Moreover, the system is equipped with a microcontroller and appropriate sensors that enable its automated operation based on measurements of the internal and external environmental conditions. A Raspberry Pi acts as a server, enabling the communication between the shading devices and the users, through an open-source home automation operating system (Home Assistant OS). The user-friendly interface, accessible via a web browser or a mobile application, provides essential data such as temperature, humidity, and device status. Alert notifications are sent when specific conditions are met. The overall system is enclosed in two 3D-printed units, ensuring its durability and easy integration into existing or new installations. In summary, this system combines the advantages of automatic solar shadings, including energy efficiency and improved occupant comfort, with smart features for remote control and monitoring through a user-friendly interface. The proposed system has been installed in a window of our laboratory, performing successfully in real-life conditions.
