Hi!

Please post working esphome config, for modbus communication.
I has multiple devices ( ESP32 with ttl converter automatic flow controll, Lillygo can with flow pin controll, Elfin ew11 modbus gateway), and the communication beetween heatpump and Home assistant is working, but with KC868-24 is not.

I use this config:

***admin*** · 01-10-2024, 10:05 AM

do you want A24 work as modbus "SLAVE" or "MASTER"?

I think, i need SLAVE. I want to read and write heatpumps, fancoils, thermostat registers.

if you want A24 work as "SLAVE", you can download KCS firmware, enable RS485 protocol, then it will work as modbus slave.

Ok, i understand the names. I need MASTER configuration for esphome.

here is video tour about esphome use by MASTER modbus controller:

Thanks. But that's not what I asked for. I need a configuration file for exactly this panel. It wasn't cheap and so I can't use it.
In the linked video using 13/16 gpio.

draw a paper, what you want A24 to do and your different devices relationship with A24.

I am attaching the requested drawing. Please read older post. Please onen links. It's not a complicated task. I was able to solve it with several tools, as I already wrote. Now I want to solve it with the A24 panel.
The task is already done at home with: https://esphome.io/components/modbus_controller.html (auto flow kontroll)
And with this: https://github.com/Xinyuan-LilyGO/T-CAN485 (flow kontroll pin define is requied)
And with this: http://www.hi-flying.com/elfin-ew10-elfin-ew11
And with this: https://github.com/Mosibi/Midea-heat-pump-ESPHome

But I want to solve it with A24.
Here is my not working esphome config.:
