ESP8266 Modbus RTU communication with Energy meter EM6400NG

In this tutorial I have shown how we can connect ESP8266 using MAX485 to TTL or MAX232 converter. Protocol :- Modbus RTU. For demonstration Schnieder make EM6400NG energy meter is used. Example code :- https://github.com/ashish8284/ESP8266_MODBUS_EM6400NG_SCHNIEDER GoodweDT /Mt inverter Integration Code:- https://github.com/ashish8284/ESP8266_MODBUS_GATEWAY_GOODWE All customization can change in settings.h file. I.e WiFi credentials, Mqtt server credentials, Mqtt payload topic etc.(for adafruit.io connectivity, efer below mentioned repo. as this feature implemented in that.) Growatt Inverter integration Code:- https://github.com/ashish8284/ESP8266_MODBUS_GATEWAY_GROWATT Feture:- webpage for local monitoring, OTA enabled, Adafruit.io connectivity. Hardware :- MAX485 To TTL converter MAX232 To TTL converter ESP8266 wemosD1Mini Modbus Library :- https://github.com/emelianov/modbus-esp8266 this library work with ESP8266 & ESP32 both chip. Credit :- Special thanks to creator of this library :- Alexander Emelianov
