adding KC868-HA RS485 zo HA or ESPHome

[dragos]

We have this setup:
Kincony F8 (Esphome) + HAv2 Rs485 + Momentary Switch (1 gang).

We've programmed the HAv2 with HA485_Ctrl_V1.0.4.0904 (address 10). If we press a button on the switch, we see feedback in HA485 assistant.
We've added these parts into esphome on F8:

external_components:
- source:
type: git
url: https://github.com/hzkincony/esphome-kc868-ha
ref: v3.0.1

kc868_ha:

uart:
- id: uart_1 #RS485
baud_rate: 9600
debug:
direction: BOTH
dummy_receiver: true
after:
timeout: 10ms
tx_pin: 16
rx_pin: 17

binary_sensor:
- platform: kc868_ha
target_relay_controller_addr: 1
switch_adapter_addr: 10
bind_output: 1
name: "binary_sensor 1"

Into the webpage that esphome displays for the F8 we see some debug info from the modbus when we click a button on the switch:
1:49:29 [D] [uart_debug:114] <<< 01:10:00:0A:00:06:0C:00:00:00:00:00:00:00:00:00:00:06:01:4E:10
but the binary_sensor 1 is always OFF.

In HomeAssistant, also is always OFF.

We've also watched both https://www.youtube.com/watch?v=S679QX6Hc6I and https://www.youtube.com/watch?v=s5Htc43HqAc.

Any ideas what else should we check? Thank you very much!
