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.

Smart Home System
Hájek, Jaroslav ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This work deals with connecting remote devices measure data of various types from physical quantities such as a temperature, a humidity to data displaying CPU or memory usage of the system to the user. The system uses Blockly to controlling logic and dependencies between devices. In the work is used lots of technologies for examples: MQTT, Websockets, GSM, Lightweight Mesh and others. The system is based on microservice which named is Flask. Flask service is an application interface for HTTP services of Python programming language. This can provide measured data by graphs and predefined components for viewing data. For controlling system was used single-board computer Raspberry Pi with a multitouch 7-inch display.

Design and implementation of the technological sample with data acquisition in the IoT environment
Vrbková, Michaela ; Hadaš, Zdeněk (referee) ; Věchet, Stanislav (advisor)
This thesis deals with the design of a technological demonstrator for data collection in IoT environment. A study of available IoT technologies was made, consisting of a description of available sensors / actuators, data transmission and processing. At the same time, the key components of the demonstrator, the AWS IoT cloud service and the MQTT communication protocol, were described. Based on the IoT technology study, a representative set of technological demonstrator elements was designed. Its functionality has been experimentally verified using the ESP8266 and ESP32 WiFi modules using Mongoose-os firmware. The result is a demonstrator of IoT data collection designed for usage in an Smart House.

Internet of Things
Piškula, David ; Nosko, Svetozár (referee) ; Musil, Petr (advisor)
This thesis focuses on the Internet of Things and some of the most important problems it faces today. Among these are the overdependence on the Cloud and lack of autonomy, poor security and privacy, complicated initialization and power consumption. The work aims to implement a complex IoT solution that solves the discussed problems. The project is part of a collaboration with NXP Semicondutors and will be used to showcase the company's technologies.

Thermostat on LinkIt Smart Platform
Bartoň, Jan ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
The bachelor thesis deals with the automation of heating regulation in the household. The goal is to design and implement a prototype of a embedded system to enable the automation of the heating control process with the emphasis on low acquisition costs. The proposed system is used to control the eQ-3 MAX! wireless radiator thermostats. The user interface of the system is the touch screen. As well as iOS mobile application that allow remote control of the system. A prototype of a Wi-Fi sensor is designed and implemented to measure temperature. The work includes hardware and software design of individual parts of the system and their implementation. The resulting system is a good basis for a low-cost system for comprehensive home automation.

Wireless Communication for Home Automation
Sezima, Václav ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
This bachelor's thesis deals with the issue of wireless communication among devices and sensors for home automation. The goal is to design and implement a device known as the gateway that is passing messages and commands between sensors and controller that controls them from central point, e.g. computer or mobile phone. A part of this thesis is also a creation of several sensors for the purpose of testing and demonstration. The gateway and sensors are based on development boards WEMOS and Arduino and supports multiple wireless technologies for communication with among themselves and controller.

Visual Home Security System for iOS-Based Mobile Devices
Bajaník, Filip ; Szőke, Igor (referee) ; Herout, Adam (advisor)
The goal of this diploma thesis is to design and implement a mobile application for home security system on the iOS platform. The application introduces a complex solution allowing the transmission of the audio and video streams between the paired mobile devices using WebRTC. The final module represents universal solution for peer-to-peer audio and video communication. The thesis also deals with the field of computer vision, namely efficient motion detection algorithms. The module for motion detection implements ViBe algorithm using Metal. In case that the motion is detected the application notifies a user with a push notification. Synchronization of application data is implemented using Cloudkit and the data persistance using Realm library.

IoT Control Module
Haman, Martin ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis deals with the research of the possibilities of wireless data transmission from the controllers IoT modules and their construction. At first there is compared wireless technologies, network protocols, their suitability depending on the application of the IoT control module. Then it is designed the IoT control module using a Wi-Fi module (based on Espressif ESP8266 integrated circuit) communicating over a MQTT network protocol. Thesis continue with selection, compilation of the firmware, creation of script for control heating system, descriptions of methods for controlling the IoT control module and display of measured data. The possibilities of creating a MQTT broker and security of data transmission are described below. In conclusion is documented and verified its functionality.
