Configure KC868-A8 in ESPHome

[land88]

digital input 1-8 can use for dry contact sensor. but whether ESPHome can calculate the pulse number, i have not tested. if ESPHome support and make sure what your water sensor pulse frequency, whether esp32 gpio speed fast enough.

For digital input it's simple, it's a binary_sensor and the platform is - platform: gpio and pin is 0,1, 2....
But for   - platform: pulse_counter what is the way to configure the PIN ? 0,1,2 doesn't oK

Who can have a configuration for pulse_counter on K868-A8 on Home assistant ?
 
Thanks

Binary sensor -> simple 

pcf8574:
  - id: 'pcf8574_hub_output'
    address: 0x24
 
  - id: 'pcf8574_hub_input'
    address: 0x22   

binary_sensor: 
  - platform: gpio
    name: "input1"
    pin:
      pcf8574: pcf8574_hub_input
      # Use pin number 0
      number: 0
      # One of INPUT or OUTPUT
      mode: INPUT
      inverted: false

  - platform: gpio
    name: "input2"
    pin:
      pcf8574: pcf8574_hub_input
      # Use pin number 0
      number: 1
      # One of INPUT or OUTPUT
      mode: INPUT
      inverted: false


But for pulse_counter, for input 0,1,2,3.... ?


sensor:
  - platform: pulse_counter
    update_interval: 2s
    pin:
      number: 21
      inverted: true
      mode:
        input: true
        pullup: true
