Abstract
Abstract—Internet of things technologies has been rapidly developed in the past decade, stimulating the development of related software products. Home Assistant is a popular home automation software. The interaction interface between Home Assistant and TouchGFX framework, which is used in the development of devices with a graphical user interface, which is based on an STM32 microcontroller, is presented in this work. The MQTT protocol, which is used to connect devices to the central server in the described system, allows the server to interact with previously known devices by using a unique identifier, which is generated when the device is connected to the system. This excludes the possibility of dynamically changing the composition of the system (adding/removing devices) without reconfiguring all interacting nodes. For this reason, it has been proposed to develop an addon for Home Assistant, which would allow devices to receive complete information on the current state of the system. To transfer received information on devices from a dynamic array to the graphical interface, real-time operating system queuing mechanisms, as well as the Model- View-Presenter design pattern, have been used. This pattern improves the scalability of the program code and simplifies the implementation of unit testing. A method has been proposed to optimize the operation of the Smart Home system under the control of the Home Assistant software.
