PZEM T004 Single-phase mains parameter WIFI logger using ESP8266

In memory of my mother, Gromova Margarita Ivanovna. Thank you, and rest in peace.

The following is a result of more than two years of efforts, in fields of PCB and schematics software mastering, C software design, ESP8266 platform development, and struggling through quirks of Embarcadero;s Firemonkey framework in C++, all in spare time between a supper, and night sleep.
Finally, ESP8266+PZEM T004 - based WIFI PowerMetering logger is here, both, as IoT firmware, and PC client software.
