Smart button for home automation
Matula, Ondřej ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
This thesis deals with the design of a smart button which will be used as a periphery to a smart home. The smart button combines the functions of the standard light switch with the ability to control other devices. The smart button communicates via a wired CAN or PWI bus. Hardware designing process which include selection of a suitable components and most appropriate technical solutions is discussed. Another part of thesis deals with implementing a firmware that allows a smart button to communicate with the master system.

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.

Home Automation Based on Arduino/WeMos/RPi Platform
Ježek, Jan ; Špaňhel, Jakub (referee) ; Kapinus, Michal (advisor)
This work aims to propose and implement a home automation system based on individual devices' connection using conditions and actions. For example, when a magnetic barrier determines that a door was opened, a command that turns on lights in the hallway is sent. However, if a card reader does not register allowed card, the alarm will be triggered. This problem is solved by a server running on Raspberry Pi, which is periodically checking all conditions that a user has defined via a web page. Based on their fulfillment, it executes predefined action. Created solution provides a way how to connect smart devices in household easily and how to automate them. Users must program each module, complex conditions, and actions by themselves. This work presents an infrastructure for communication and examples on how to create such modules.

Smart digital door lock system using IoT networks
Vitula, Marek ; Kincl, Zdeněk (referee) ; Záplata, Filip (advisor)
This master thesis describes the design of a battery-powered smart lock using IoT networks and NFC technology for user authentication. The first part of the thesis describes the individual components to be used for the device design and also deals with the design of matching circuits and the antenna for the NFC. The following part of the thesis describes the design of the hardware, particularly the design of the printed circuit board. The third part describes the firmware and the final part of the thesis is dedicated to the security analysis.

Intelligent Presence Detection
Kronika, Vojtěch ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
In this work I dealt with the solution of indoor localization, its design and implementation. We are at a time when the topic of smart home is a daily affair and the solution for indoor localization does not have a certain winner yet. The goal of this work is to create an intelligent presence detector, using Bluetooth technology, which recognizes in which room the device is located. And it estimates in which part of the room the device can be located. To achieve the goal, I use at least three sensors in each room and compare the signal strengths between the sensors and the localized device. A Kalman filter is used for a noise reduction on data signals from sensors. The result of the work is a functional solution for indoor localization. I have found that it is not easy to use rapidly changing signal strength within triangulation to obtain the exact position of the device. Further work could address what needs to be done to make triangulation possible and functional. One of possible directions is an exploration of Bluetooth Direction Finding technology.

Trully Smart Smart Socket
Valušek, Ondřej ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
There is a large selection of so called smart sockets available on the market today. The possibilities of these sockets are sadly very limited. Typically, they can measure power consumption, be turned off and on remotely by mobile application and timer. This thesis deals with this problem by showing how a smart relay can be used to create a truly smart smart socket that can classify currently connected appliances using just short time window for up to three devices combined. The power consumption is measured using Shelly 1PM together for three plugs. Using time series feature extraction, unknown device detection with SVM and neural network classification, the accuracy was over 99%. on a dataset containing combinations of smart TV, lamp and a laptop consumption. Information about currently connected devices is displayed on a webpage and written to a database to be viewed later. The information about connecting and disconnecting a device can be further sent to a system for smart home management.

Simulation-Based Development of Heating Control System
Tomeček, Jan ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
This thesis is about optimalization of boiler heating from external sources. I have created a simulation model of Heating Control System. Subsequently, using a simulation model, I proposed possible optimizations for water heating control. The used optimization method was deep Q-learning. The result of this work shows the use of simulation for the development and optimalization of control systems.

Risk Analysis of Smart Home Technologies within the Internet of Things Concept
Brych, Patrik ; Procházková, Danuše (referee) ; Urbánek, Michal (advisor)
This diploma thesis deals with modern technologies that are used as smart home equipment. The analysis of the current state is devoted to the concept of the Internet of Things, into which smart home technologies can be included. The research part is focused on the analysis of risks that are associated with the implementation and use of smart technologies. Financial, technical and security risks are analyzed using adequate research methods. Financial risks were analyzed using the financial plan of the model house. Technical, which also included process risks, and security risks were analyzed using network analysis methods and risk analysis methods. The network graph method and the project evaluation and control method (PERT) were used for the analysis of process risks. The analysis of technical and safety risks was performed using the Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) methods.

Design and Implementation of IoT for Monitoring and Control of Smart Homes
Smejkal, Jakub ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
This thesis deals with a generic design and implementation of an IoT system, specifically for a smart home. The thesis aims to compare existing systems and hardware solutions. In this thesis there are a few examples of hardware firmwares and a prototype of a software for controlling and monitoring. The selected problem is resolved by designing a general system for a smart home. As a sample implementation, the system will be created by using hardware devices from Czech company HARDWARIO and sensors from various vendors. It will contain some environmental sensors, motion detectors, etc. The implemented prototype of an application allows easy monitoring of the whole home in one place thanks to an uncluttered UI, which is fully customizable for the user's needs.
