how to integrate KinCony modbus energy meter to home assistant using raspberry pi's RS485 port
A. use "inCony_Meter_config_tool" change RS485 " Parity: EVEN " to " Parity: NONE ", because we found home assistant can't work with "EVEN", KinCony energy meter default setting is "EVEN".
A-1: connect energy meter to PC by USB-RS485 adatper:
A-2: first time, use RS485 setting, Parity: EVEN (Chinese word on left is : 偶校验) click "打开" (open serial port) button.

A-3: click "无校验" (None) button, set Parity: NONE
until now, "Parity" is set completed.
if you want change meter ID from 1, you can "set the meter ID", such as input 1,2,3,.... then click "改表号+读" (write button), it will set the ID for meter.
if you have changed Parity: NONE, you want connect to serial port again, you need change serial setting, Parity=None, Chinese word is "无校验",then click "读" (Read) button, you will read all data from meter.
now the meter hardware setting is complete, then you can connect meter to KC868-Server or Server-Mini's RS485 port directly. see photo:
