Automação residencial utilizando OpenHAB e Home Assistant

Abstract

Over the years, the search for new things has resulted in great technological advances, especially in the areas where it is used, making several processes that were once considered simple but manual more sophisticated and convenient. Home automation is a great example of the evolution of technologies that have been acquired over the years. Thus, this work aimed to create an efficient and intuitive home automation system, which was implemented in the IFMaker laboratory of the Instituto Federal de Goiás-Câmpus Itumbiara. The automation system is capable of receiving data from the temperature sensor and sending information through infrared LEDs, providing the user with control over the activation of equipment such as projectors, televisions, sockets and air conditioners through the interfaces of the OpenHAB (Open Home Automation Bus) and Home Assistant platforms, working in an integrated manner, using their main advantages, with low cost through their free resources. To fully function, the two platforms mentioned above require an MQTT server. The Raspberry Pi is a minicomputer widely used in low-cost home automation systems, and it also eliminates the need to allocate and/or use personal notebooks to run the server and all other software and platforms. In order to facilitate the installation of all programs and ensure optimal performance at the same time, the Container method was used, using the Docker software. Communication between all devices is via the MQTT protocol using the publish and subscribe method, with clients and the server (broker) operating as the basis. OpenHAB and Home Assistant are two platforms that can communicate with several brands that have devices in the Home Automation area. They provide customers with a wider range of equipment available on the current market that can be controlled, automated and viewed from any location through their interfaces for devices with screens.
