RE: RS485 modbus energy meter integrate to ESPHome yaml file for home assistant - JCh - 06-13-2023
Hello,
Is it possible to use RS485 on the KC868-A8S to read data according to IEC 62056-21, mod C , 7E1 via ESPHome? It is not Modbus RTU.
Thank you
RE: RS485 modbus energy meter integrate to ESPHome yaml file for home assistant - admin - 06-13-2023
i am not sure whether ESPHome support that protocol, i think it's not easy, suggest use by modbus.

Hi!
Do you have ESPHome sample configuration for Kincony 3-phase RS485 energy meter? Model KC868-Meter-7P-RTU

Hi, trying to set this up to work in a KC868-Server. I'm having a few issues:
Error:
[09:17:47][D][modbus_controller:043]: Modbus command to device=1 register=0x76 countdown=0 no response received - removed from send queue
[09:17:48][W][modbus_controller:136]: Duplicate modbus command found: type=0x3 address=142 count=4
Config attached: config_modbus.txt
Photo attached of wiring.
Thank you

because now will begin China new year holidays soon, when we have free time, will test it. maybe can make a YouTube video tour for you.

Tried re-setting the address to 222 (0xDE) but and also inverting tx with rx pins but got the same results ... any help will be much appreciated.

I had to remove lines including count: 2 for config to work.
Once valid config I don't see values displayed, see attachment please.
After enabling DEBUG for modbus I see:
