KC868-HAv2 Modbus firmware

[mrwolfj]

yes, it's a special verison made for MODBUS protocol.
if you just use by ESPHome, suggest use our private protocol, already have video tour and yaml for that.

The problem is that I would like to use it in a big project and I would like to have only one RS485 line. Instead, if I will use the stock firmware I must use at least 2 RS485 lines, one only for HAv2 and the other one for Modbus devices.

If you don't have any special version for V2 that supports Modbus, could you at least send me some specs in order to create a custom firmware? So the development will be a little bit easier for me

Thanks!
