Input Flickering Issue with KC868-A16

[amir]

I'm using a KC868-A16 controller with ESPHome and I've encountered an issue with two inputs that occasionally "jump" - turning on and off by themselves.
to input 03 nothing is connected

 I'd appreciate any help in resolving this problem.

let these digital input port connect to GND or 12V. Do not hang pins in the air. test for one day have a look.

hi and thanks for the Quick response
this is happening on port 16 with GND connected

name: "KC868-A16-X16"
pin:
pcf8574: inputs_9_16
number: 7
mode: INPUT
inverted: false

The debounce filter ensures that the input signal is stable and ignores short, unintended changes (debounce is used to filter out the bouncing effect of mechanical buttons).

Code:

# Configuring a binary sensor (button or switch input)
binary_sensor:
  - platform: gpio  # Use the GPIO platform to read the input
    name: "PCF8574 Input 7"  # The name of the sensor, visible in platforms like Home Assistant
    pin:
      pcf8574: pcf8574_hub  # Reference the PCF8574 hub ID defined earlier
      number: 7  # The input will be read from pin number 7 on the PCF8574 chip
      mode: INPUT  # The pin mode is set as input
      inverted: false  # Whether the signal is inverted, false means it's not inverted
    filters:
      - debounce: 50ms  # The debounce filter to delay by 50 milliseconds to handle button bounce
    on_press:
      - logger.log: "Button Pressed"  # Logs "Button Pressed" when the button is pressed
    on_release:
      - logger.log: "Button Released"  # Logs "Button Released" when the button is released
