Model-Based Design of Smart Home Control
Čada, Roman ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
This work deals with model-based design of Smart Home control and implementation of this system. The goal is to create a model that serves as a design and according to this model implement the system. Model-based programming tools do this well. The work first describes the model-based design, the modeling languages that are used to create such a design and the technologies that are used in Smart Home. Based on this knowledge, the model is created as a design using the SysML modeling language and then this design is implemented using PowerDEVS and Node-RED.

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.

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.

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.

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: Digital Thermostatic Valve Controlled via WiFi
Smejkal, Jan ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
This bachelor thesis deals with smart home heating in households with radiators. The goal is to design a cheap digital heating head and to integrate it via WiFi and MQTT into the Home Assistant system. I have focused on keeping good design, head functions and a good user experience. Home Assistant enables showing graphs using InfluxDB and Grafana. Using a program in tool Node-RED enables it to lower heating temperature at the times of user absence and to schedule heating temperatures. The price of the complete unit is under 400 CZK. Temperature regulation was provided by a prediction controller, but it was replaced by a PID controller. The controller can regulate with the difference of maximal and minimal temperature of around 2 C. The user can control the boost mode of the head via a physical button or using the Home Assistant system. The resulting product is a good basis for a low-cost smart heating system.

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.

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.
