KC868-meter-7pv-rs485

Forgive me for posting this here as i couldnt find a suitable forum section to post it in. 

Does anyone have a working esphome yaml for the KC868-meter-7pv-rs485 3 phase power meter? 

Thankyou in advance.

Ok thanks that seems to be a single phase version, also it doesn't answer my question. If there isn't a esphome yaml available for the  KC868-meter-7pv-rs485 3 phase meter, is there at least a published specification of the modbus address and registers for this device so i can write a config myself?

it's same protocol, the address is same.
here is protocol:
Modbus-RTU: 9600 E 8 1  read function:03 

Register address(decimal      data            data type-IEEE-754      function

0000, 0001              power consumption (kWh)        Float                        read
0100, 0101                  voltage (V)                                  Float                        read
0106, 0107                  current  (A)                                  Float                        read
0118, 0119                  power (kW)                                  Float                        read
0142, 0143                  power factor                                Float                        read
0144, 0145                  frequency                                      Float                        read

How to change meter ID, for example: change ID:01  to 20 just send command:
01 10 0D B0 00 01 02 00 14 60 AF
first (01) current ID
14 is (20) decimal
60 AF (CRC)

Ok that reports the first phase, what about the 2nd and 3rd phase on this device?

How to change meter ID.
for example: change ID:01 to 20 just send command:
01 10 0D B0 00 01 02 00 14 60 AF
first (01) current ID
(14)hex is (20) decimal
60 AF (CRC)


ID:1 meter modify "parity" to

01 10 0D B7 00 01 02 [00 00] (61 17)  None
01 10 0D B7 00 01 02 [00 01] (A0 D7)  ODD
01 10 0D B7 00 01 02 [00 02] (E0 D6)  EVEN

( ) is CRC code  [ ] is different setting

ID:1 meter modify "Baud rate" to

01 10 0D B6 00 01 02 [12 C0] (6C 36) 4800bps
01 10 0D B6 00 01 02 [09 60] (66 B3) 2400bps
01 10 0D B6 00 01 02 [04 B0] (63 B2) 1200bps
