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:

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.

[admin]

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.

[admin]

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

[Yocee]

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.

[admin]

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.:
