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

Modbus Library :- https://github.com/emelianov/modbus-esp8266
this library work with ESP8266 & ESP32 both chip.
