/**
 * @supla-example
 * @file Pzem_V_3.ino
 * @brief Example of connecting a Peacefair PZEM-004T V3 energy monitor to SUPLA using an ESP8266/ESP32.
 * This example demonstrates how to integrate a PZEM-004T V3 energy monitor with an ESP device
 * and send its readings (voltage, current, power, energy) to the SUPLA cloud via Wi-Fi.
 * It includes a web server for configuration.
 * Network settings are configured via the web interface.
 * Users need to adjust the RX/TX pins for the PZEM module, and optionally the PZEM address in the code.
 * A status LED is also configured.
 *
 * @dependency https://github.com/mandulaj/PZEM-004T-v30
 * @tags PZEM, PZEM-004T, V3, energy, monitor, voltage, current, power, esp, esp32, esp8266, wifi, web_interface, modbus
