Comparison of Cloud Systems for Smart Home
Sobol, Patrik ; Zbořil, František (referee) ; Janoušek, Vladimír (advisor)
This thesis deals with comparison of the biggest cloud computing platforms, Amazon and Google, with high interest in services focused on smart home. It examines connection of services between each other and it summarises options of data transport between device and cloud using protocol MQTT. By integrating of cloud services dashboard is created, which allows to control devices in household.

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.

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.

FLATcon system – flat control system with RF communication
Krivoklatský, Filip ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This bachelor’s thesis discusses solutions of smart houses. It presents some of the available solutions on market and points out its positives and negatives. The thesis itself focuses on solutions which support wireless communication. Subsequently, the design of custom solution named FLATcon is being proposed. It includes designing of central unit, which is the main part of the system. First, the hardware part is being designed. Base of this is minicomputer Raspberry Pi 3 B with necessary inputs and outputs. Uninterruptible power supply and wireless communication interface are also part of the design. Subsequently, thesis focuses on control software design and on user interface in form of web server. At the end of this thesis, achieved results are presented.

Supervision and Control System for a Hotel Implemented by IoT Means
Hockicko, Matej ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
This work solves the design and prototype implementation of supervision and control system for a hotel implemented by IoT means. The solution is based on ESP microcontrollers, which control the connected sensors and actuators. ESP devices are futher grouped and connected to central point within range. Using this point, MQTT communication is futher transmitted to the cloud. The cloud runs the IoT Core service, which allows to control and store the status of devices. There is also a Node-RED developmnet tool, in which a graphical interface was created for this system. The result of this work allows remote monitoring and control of the hotel using sensors and actuators connected to this network.

Security Analysis of Smart Home Devices
Grofčík, Peter ; Kmeť, Martin (referee) ; Matoušek, Petr (advisor)
Main purpose of my bachelor thesis is to analyze security of smart home devices and afterwards to test and confirm exposed vulnerabilities on these devices. The first section describes MioSMART kit devices used for analysis including ways, how to access them. The next section describes communication of smart home devices including protocols, that are used for it. In the next chapter, free tools are introduced to identify vulnerabilities in IoT communications. The next section contains description of network attacks that were carried, based on detected vulnerabilities to damage the functionality of smart home devices. Part of this chapter is dedicated to the description of monitoring options for ongoing attacks on smart home devices.

Integration of Sensors and Actors into the BeeeOn System
Šišmiš, Lukáš ; Korček, Pavol (referee) ; Sakin, Martin (advisor)
The goal of this thesis was to extend BeeeOn system with a Vektiva module and to do a research on possibilities of Smarwi implementation, which not only included studying different communication protocols that the device uses, but also comparing them and choosing the most suitable protocol for the implementation. In the beginning of the thesis, BeeeOn system and its' components are described followed by the description of implementation and testing pocess of the Vektiva module and the Smarwi emulator.

Secure Gateway for Wireless IoT Protocols
Hošala, Martin ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
Táto práca bola zameraná na vytvorenie funkčného prototypu zabezpečenej brány pre bezdrôtové IoT protokoly s využítím BeeeOn IoT Gateway. Na vytvorenie výsledného riešenia bolo potrebné analyzovať existujúce zabezpečovacie systémy IoT, navrhnúť ich integráciu s BeeeOn Gateway a systém nasadiť. Ako zabezpečovacie systémy v tejto práci boli použité moduly NEMEA vyvinuté v rámci projektu SIoT. Výsledné riešenie beží na routeri Turris Omnia a pozostáva z BeeeOn Gateway, piatich detekčných modulov SIoT a ďalších modulov NEMEA potrebných pre plnú funkčnosť detektorov. Potenciálne hrozby sa zisťujú v sieťach Z-Wave, BLE a LoRaWAN. Používateľ môže so systémom interagovať prostredníctvom webového rozhrania systému Coliot, ktorý je tiež súčasťou výsledného riešenia a slúži na ukladanie a prezentáciu výsledkov detekcie. Funkčnosť systému bola overená experimentálne a množinou integračných testov. Testovanie odhalilo mnoho nedostatkov spojených s použitými podsystémami a väčšina z nich bola opravená. Výsledný systém sa používa sa v rámci projektu SIoT.

IoT system for conference room control
Kondás, Peter ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
The goal of this bachelor´s thesis was to design and implement a system for monitoring room occupancy by counting the entries and exits of individuals from the room and chair occupancy detection, with the system sending data using the MQTT protocol. A device was designed for the system and components and sensors were then selected to further expand its capabilities. Home Assistant was used as the user interface for this system, providing a clear representation of the current state of the conference room.
