System of Intelligent Flower Pots for Indoor Plants Growing
Kinc, Michael ; Mrázek, Vojtěch (referee) ; Šimek, Václav (advisor)
Nowadays, when technologies from the world of the Internet of Things are gaining popularity, new possibilities are opening up for the automation of common daily tasks with the help of smart devices. Such a device is also an intelligent flower pot, thanks to which the premature death of the plant can be prevented, as it may be able to warn the grower in time of deteriorating values measured from the soil or the surroundings of the monitored plant. The goal of this work is to create a system of intelligent flower pots for indoor plants growing, which can be controlled through an information system and a web application, in which the user has an overview of his flower pots, the state of the plant and the measured values.

Visual Programming of IoT devices
Podvojský, Lukáš ; John, Petr (referee) ; Hynek, Jiří (advisor)
This thesis aims to provide end-users with a visual programming tool to simplify the process of creating programs for Internet of Things (IoT) devices. There are a lot of different types of IoT devices that use various communication protocols. The lack of standardization for these devices forces companies to create customized solutions. Users are then presented with a predefined functionality that can be only slightly altered. One of the solutions for this lack of ability for end users to customize device behaviour is to give them more freedom through the concept called visual programming. This thesis results in a new library implementing a visual programming language and a visual editor whose output is a serialized program form that can then be transformed into the language of the target devices. The resulting library is created using web technologies and can be integrated into existing solutions.

Post-quantum Secure Communication in IoT
Goldshtein, Daniil ; Ricci, Sara (referee) ; Malina, Lukáš (advisor)
Tato práce se zaměřuje na současný stav post-kvantové kryptografie a její využitelnost v omezeném prostředí internetu věcí. V teoretické části stručně popisuje aktuálně známé typy post-kvantových algoritmů a analyzuje jejich nejlepší implementace, buď již doporučené, nebo té, které jsou nejbližší pro další standardizace. Zaměřuje se také na existující výzvy a omezení týkající se Internetu Věcí. Praktická část této práce je věnována srovnání více knihoven z hlediska jejich modularity, účinnosti zdrojů, podpory a výkonu při provozu se standardizovanými post-kvantovými algoritmy. Dále je věnována vývoji funkční implementace řešení poskytující ověření dat pomocí kvantově odolného digitálního podpisu a jejích šifrování. Výsledky všech testů jsou systemizovány v tabulkách. Závěr práce obsahuje závěrečnou analýzu a shrnutí výsledků, dosázených pomoci vyvíjené implementace.

Cryptographic algorithms for low-power IoT devices
Oszelda, Matěj ; Dobiáš, Patrik (referee) ; Dzurenda, Petr (advisor)
The bachelor thesis analyses the possibilities of application of operating systems, cryptographic libraries and their primitives in memory, performance and computationally constrained IoT environment. It then implements selected tools for securing communication in a system with constrained IoT devices. The theoretical part discusses the IoT, the different operating systems and cryptographic libraries in this environment. It then presents the measurement and comparison of cryptographic libraries and their primitives. Based on the measurements, it selects tools for implementation in securing the communication of IoT devices. It then creates a design and implements the system.

System for Automatic Heating Control in Holiday Homes
Ježek, Lukáš ; John, Petr (referee) ; Hynek, Jiří (advisor)
The goal of this bachelor thesis was to design and implement a system for controlling heating and water heating in buildings divided into multiple zones with multiple heating sources. Typically larger and older holiday homes such as farmhouses or larger cottages that do not have only one heat source, however, the system will also be applicable to newer buildings. This system can be controlled either remotely or locally. RaspberryPi 4B was chosen as the platform from the IoT sector. This system solves, for example, the integration of a fireplace insert into a heating circuit together with a boiler, combi boiler or other heat source. Of the existing solutions, none allow efficient use of multiple sources with zoning, or the solution is expensive and inefficient. Moreover, the system offers extensibility to other IoT circuits.

Smart house
Sedlák, Šimon ; Pospíšil, Jiří (referee) ; Baláš, Marek (advisor)
This thesis describes the technologies of energy self-sufficient homes, their sources, and methods of energy accumulation. It also deals with current possibilities and trends in the field of smart living. A smart energy system is introduced, which has a direct impact on energy consumption in households. The practical part of the thesis involved simulating the energy system and comparing the impacts on purchased electrical energy from the distribution network based on the proposed variants. These included the size of the photovoltaic power plant (PV), the accumulation of electrical energy (EE), the accumulation of heat, the insulation of the building envelope, and more. All results that demonstrate the impacts of the energy system and the proposed renewable energy sources (RES) were summarized in the final part of the thesis.

Autonomous control system for composite materials heating
Lapčák, Adam ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
This thesis focuses on designing an autonomous system intended for heating surfaces made of conductive composite material. The design involves smart electronics design for integration into distribution boards and the ability to control power switching elements. Emphasis is also placed on the possibility of remote system control via the internet network. For an easy deployment in any location, the autonomous system will use a mobile network. System control will be realized with a dedicated HTTP API server along with a custom user application.
