Add KinCony modbus energy meter to home assistant using raspberry pi's RS485 port

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:
