KC868-HA RS485 Button Adapter Released

[Rafael Morais]

Hello,

I'm facing some issues to connect KC868-HA board using RS485 Modbus in ESPHome. I'm using the KC868-AI board to communicate with KC868-HA board from RS485 bus.
I also connected the momentary switch at the KC868-HA. I'm using the 6 gangs wall panel (https://www.kincony.com/metal-frame-mome...panel.html)

   
   
   

In KC868-AI yaml file, I put the following code to initialize the RS485 communication and it works so far:

Code:

uart:
  id: mbus
  tx_pin: GPIO14
  rx_pin: GPIO16
  baud_rate: 9600
# RX and TX pins defined according to KC868-AI ESP32 IO pin definition (https://www.kincony.com/forum/showthread.php?tid=2016)

modbus:
  id: modbus1
  uart_id: mbus
  send_wait_time: 200ms

modbus_controller:
- id: switchbedroom
  address: 1
  modbus_id: modbus1
  update_interval: 1s

At the "binary_sensor" section, I put the following code:

Code:

binary_sensor:
  - platform: modbus_controller
    modbus_controller_id: switchbedroom
    id: pulsador1
    name: "pulsador1"
    register_type: read # or coil or discrete_input. I don't know
    address: 1

The problem is that I don't know how to proper configure this "binary_sensor" section to read the KC868-HA modbus codes. 
I saw the documentation at this forum (https://www.kincony.com/download/KC868-H...-board.pdf) but I can't configure this section. 

Here is the KC868-HA configuration:
   

When I see the logs for the KC868-AI, I have the following:

...

Could someone help me?
