If other customers arent having an issue, then it must be either something with my set up.
I would much prefer to find the cause of the issue as I want to buy more of these items for my desired application.
The problem is I dont have much knowledge of RS485 applications, so was hoping to follow your guide and adjust as required. I have tried again by factory resetting the KC868-HAv2 and using your exact code for ESPhome as per your post https://github.com/hzkincony/esphome-kc868-ha.
From what I can see when I have the RS485 USB connected to a computer using the HA485 Assistant software, it doesnt show anything received when I toggle on the switch for the LED in Home Assistant. So I dont think that the command over RS485 is being sent, even though the ESPhome logs say it is.
How can I test this from a computer?

So I have just used another application called Serial Port Assistant https://github.com/KangLin/SerialPortAssistant and from that I can see data on the RS485 when I press a button connected to the KC868-HAv2, I can even copy that data string and send from the software and Home Assistant sees the button press the same.
However, when I turn on "Switch 1" in Home Assistant to toggle on the LED connected to the KC868-HAv2, ESPHome log outputs this " [23:22:45][D][uart_debug:114]: >>> 01:03:12:55:BB:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:01:30:4B", but I dont see that on the Serial Port Assistant software.
I will buy one of your KC868-A2 boards to test, maybe it is the board that I am using causing the problem.
