KC868-meter-7pv-rs485 - drboom - 11-17-2023
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?
RE: KC868-meter-7pv-rs485 - admin - 11-17-2023
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?
