Smart Home
Konstantinov, Glib ; Musil, Petr (referee) ; Mlýnek, Petr (advisor)
The bachelor’s thesis deals with the analysis of intelligent devices and the possibilities of their usage in the household. Furthermore, the possibilities of using electricity from a photovoltaic power station and their comparison in terms of financial savings and efficiency of use are described. Moreover, in the theoretical part, a smart metering is described and methods of monitoring electricity consumption from classic electricity meters are presented. The practical part focuses on measuring the consumption of electricity by home appliances using a smart plug with the aim of their categorization, measuring the quality of electricity using a quality monitor MEg44PAN. The output of the bachelor thesis is the visualization of ways how intelligent elements can be implemented into existing buildings, smart homes and various combinations of appliances and resources.

Smart Home Open-Source Components
Kúšik, Lukáš ; Letavay, Viliam (referee) ; Pluskal, Jan (advisor)
The aim of this thesis is to examine the state-of-the-art commercial elements found in smart home households. Their freely available alternatives are explored, together with three open-source home automation platforms. We review freely available microcontroller development kits, usable for the development of smart sensors. After that, using a suitable combination of electronic components and microcontrollers, components are designed and implemented for our own smart home system, utilizing the Home Assistant platform. This incorporates a built-in redundancy, designed to withstand cases of a failure of any component. The developed tool uses container orchestration technology, real-time file synchronization and automatically configured database clusters, to achieve a unique and comprehensive solution to high availability of Home Assistant.

Gateway for Smart Home
Čechmánek, Martin ; Žádník, Martin (referee) ; Novotný, Tomáš (advisor)
In area of Smart-home control, there are requirements for miniaturisation, security and advanced control logic of individual member of system at present. One of the challenges is the way of data collecting from terminal nodes and data processing, including their distribution to the others nodes of Smart-home. The goal of this thesis is to design and to produce Smart-home control node, which will be a gateway between sensoric net and database and will be developed and produced on embedded system with speci c HW boards. Functionality of this gateway should include error states, e.g. should cache sensor messages when the connection between gateway and server interrupts, or take care about time synchronising. The thesis describes theoretical side of gateway design and also practical side of programming and producing SW for the gateway in Smart-home system.

Development of an IoT System for Home Appliances
Vančo, Timotej ; Kaczmarczyk, Václav (referee) ; Lázna, Tomáš (advisor)
The aim of the bachelor thesis is to make a research of the current state of IoT and then propose the creation of my own IoT solution for smart home. It also aims to select the appropriate components for the custom solution from which the system will compose and design an appropriate communications interface with option to secure communicate with each other. Then revive the hardware of sensor modules, actuators and control system. The system should be capable of displaying measured data and enabling actuators to control. The final goal is to control the system with voice commands. The theoretical part is focused on description of what is IoT, history, usage and near future of IoT. Furthermore, the currently used IoT classifications and IoT systems in smart homes are described from a commercial and open-source perspective. The theoretical part ends with the comparison of voice assistants and the way the text is understood by the computer. The practical part deals with the description of own solution, selection of components for modules, creation of printed circuits, designing boxes for 3D printing, creation software for individual modules for measurement, communication and control of intelligent home. Next, I am writing about a system that displays measured values from modules, creates a user interface, and controls action members using buttons or voice commands.

Server for Collecting Sensor Data and Control of Active Elements
Halaj, Jozef ; Hujňák, Ondřej (referee) ; Viktorin, Jan (advisor)
Bachelor's thesis aims on communication with remote sensors and active elements in the smart home system called BeeeOn. The individual parts of the BeeeOn system are described with respect to the current insufficient communication principle and implementation. For communication with BeeeOn gateways, the WebSocket technology is used. It allows communication on netwoks with a restricted access to privileged ports. The implemented server is in principle capable of serving a high number of BeeeOn gateways that works as a bridge among the server and the remote sensors. The communication is secured with SSL/TLS, it uses confirmation mechanism to guarantee reliability and it is easily extendable by other protocol messages. It enables the system to send asynchronous commands to the BeeeOn gateway and to the connected devices. The server is implemented in C++ language. The most common communication scenarios were tested by automated tests.
