The thesis describes the development process and configuration of a three-phase complex electricity meter, which is intended for use in households on the house electrical installation. It shows us electricity consumption data live on the mobile application and on the Internet. Thus, we can check the household consumption at any moment and have collected data for past periods.
The electricity meter consists of three PZEM-004T-V3.0 modules, an ESP32 microprocessor and a power supply. A printed circuit board with brackets for attaching it in the electrical panel is also designed. Furthermore, the thesis describes the necessary configuration of PZEM modules and the installation of the ESPHome and Home Assistant software for the correct operation of the meter and data display.
The produced meter was finally tested in the laboratory at the college and compared with a similar meter available on the market.
