M-Bus in building automation
Sluka, Filip ; Vojáček, Zdeněk (referee) ; Marada, Tomáš (advisor)
This thesis is about the M-Bus (Meter Bus), which is the industrial bus for the energy consumption data and the state values transmission in the building automation systems. This document describes signal transmission principle, M-Bus protocol, network topology, the types of components, the M-Bus wireless version and also provides summary of the M-Bus technology and the comparison with its alternatives.

Unwarranted Energy Consuption Occurence Analysis Using of On-line Consuption Evaluation Provided by Remonte Reading Instalations
Samuel, Tomáš ; Kristek, Petr (referee) ; Orságová, Jaroslava (advisor)
The target of this project is to show the analyses of unauthorized subscriptions electricity consumption and provide the option of distribution networks screening on-line through istalment the devices providing remote control. This way of elimination the causes of unauthorized consumption has been not commonly used in the Czech Republic yet, it is pre-pilot project. We should be announced about the ways of measuring the electricity consumption used in past and nowadays. At present, there is a significant increase in case of unauthorized donations of electricity. Operators of distribution networks pay increased attention to these issues and develop efforts to reduce non-technical losses in the distribution and trade in electricity, which in its consequences lead to increase in costs with an impact in electricity prices. On business conditions and performance of government in the energy sectors and amendment of some laws the definition of certain terms of irregular donation electricity characterized by the provision of energy bill, which is a precondition for their qualifications. The analyses of unauthorized consumption based on on-line measuring with tending to make it easier and cheaper is useful for future, of course it might substitute the pretty expensive ways of measuring actual energy consumption. The result of it should by presentation of numeric energy flux diagram. There is a growing frequency and social insecurity of unauthorized of electricity and it is primarily on the distribution system operator, consistently privileges resulting from the energy bill and other generally binding regulations. The system lead to revealing unjustified interference with measuring equipment for which data on consumption are registered or recorded incorrectly or other useful functions.

Compact System for Autonomous Meter Reading
Podeszwa, David ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
This work solves the problem of the insufficient range of WMBUS meters, which makes their reading still difficult. The developed implementation solves this problem by using a battery-powered device that extends this range by using a LoRaWAN network, where the data received from the meters is sent over this network for further processing. The created device is capable of receiving WMBUS frames and sending them for a minimum period of 9 years. The main benefit of this work is the implementation of such a device on the new STM32WL platform, which is unique due to its integration of a microprocessor and a Sub-GHz receiver inside one chip.

Open-Source Implementation Of Smart Home Gateway For Z-Wave Protocol
Krejci, Jan
Z-Wave protocol is one of the most popular wireless protocols for home automation or smart home. However, in recent years there have been only few studies on practical measurements of this protocol. There are several manufacturers on the market, implying a vast array of devices, as well as deploying a commercial solution to the home is expensive and mostly focused on a single manufacturer’s portfolio. In this article, we designed and implemented our own Z-Wave home gateway for a smart home system based on open source software. We verified the feasibility of the proposed gate using the prototype and evaluated its performance according to the execution time of the command. We also discussed the limitations of the Z-Wave protocol based on our experience.
