Coordination of MicroPython-Based IoT by Means of Node-RED
Kolář, Josef ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
The target of this thesis is to create means for using the Node-RED tool to coordinate physical nodes in the form of ESP32 chips in the Internet of Things. This is fulfilled by created Node-RED extension, the proposed MQTT channel protocol and custom firmware for these nodes. All of this suport deploy of diverse applications to nodes simultaneously side by side. The designed and implemented MicroPython firmware is capable of asynchronous operation of individual applications which provides an interface to communicate with the Node-RED. The functionality of this system has been successfully validated on the basis of two practical usage scenarios that demonstrate the possibility of direct use deployment system into practice in automation - even with the included firmware installer.

Design and realization of data processing system from environmental sensors in IoT environment
Maraczek, Patrik ; Bastl, Michal (referee) ; Věchet, Stanislav (advisor)
The master’s thesis deal with design and realization of measuring station, which process data from environmental sensors in IoT environment. Thesis includes research of sensors, cloud services for IoT, microcontrollers and environmental data available online. Thesis contains detailed procedure for realization of designed system, including code description for microcontrollers STM32W55 and STM32 B-L475E-IOT01A2 Discovery kit, configuration of IBM Watson IoT Platform cloud service and procedure for correct programming of Node-RED application responsible for logic of whole system. Source code, which might be used for simple implementation of designed system, is attached to the master’s thesis.

Distributed Control System with Dynamically Evolvable Nodes on RPi Zero Platform
Szymik, Michal ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This work focuses on the development of a distributed control system that runs on multiple Raspberry Pi Zero devices and enables dynamic reconfiguration of its topology. The platform is implemented in Python in the form of a runtime environment. This work also describes how to develop applications for this system and introduces a script that facilitates the installation of an application onto the system nodes. The system described works and a sample application demonstrates its functionality.

Management and Automation of Enterprise Facility Heating System
Hartmann, Jiří ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
The aim of this work is to create a unified control and supervision system, SCADA, for controlling the heating and cooling of the company. The system is controlled by UniPi PLC units. Node-RED is used as control software. The user interface is created by an extension "dashboard". For communication between elements using the MQTT protocol. The InfluxDB database is used for data storage. The Grafana tool is used to visualize historical data. The majority of the created system consists of open software. The system is universal, expandable and it is possible to connect it with another system. The system can be used or adapted to similar problems of advanced heating control.

Well Water Level Measurement
Samek, Jakub ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
This thesis deals with the well water level measurement. The main aim was to design and construct a device using proper platform and sensorics for measuring which is used for measuring the water level in the well. This device uses batteries. The expected battery life is several months. The device sends collected data via network to the server. These data are visualised in graphic interface using a graph. The system controls the water level in the well and battery level of the device. When the limit values are exceeded, the user is notified by e-mail. Based on this information, the user can decide how to be economical with the water.

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.

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.

Smart Home Implementation by Means of Eclipse IoT
Heřman, Kristián ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The aim of this work is to design Smart Home control application by means of Eclipse IoT, its assembly and comparison with the standard control application. Reference application is realized by a combination of Node-Red and Home Assistant applications. However, the reference application will overcome the proposed solution both in practical usability and user-friendliness.
