Hi,
first of all I like to thank you for your effort und your tutorials about Modbus and ESP8266! This is highly appreciated!
Due to my lag of knowledge about Modbus stuff, I just can't figure out a plan how to use your codes to integrate my actual Modus device into my Home Automation System.
Here is what I have:

• a server (ODROID C1) running Home Assistant with Modbus sensors
• an energy meter "Eastron SDM630" (Modbus device (client?))
• a bunch of ESP8266 boards

Now I'd like to use an ESP board as a fully transparent ModbusTCP-to-ModbusRTU gateway, that just forward/converts all traffic from ModbusTCP-to-ModbusRTU and vise versa. But as I understand your code, you use a predefined amount of registers (ten for each direction) and fix addresses.

As I said, my Modbus knowledge is very limited so sorry in advance for the following questions:

1. Why do you use a predefined amount of registers and fix addresses?
2. Would it be possible to modify it that way, that it is really a pure "stupid" converter from ModbusTCP-to-ModbusRTU, so that it does just forward addresses, data, CRC, etc.?
3. Does your code eventually already support what I want but I just missed it?
