Configure KC868-A8 in ESPHome

[juan]

Hello,

I'm trying to configure one of the relays on the board as a momentary relay, but I can't get the configuration right.

according to ESPHome the code should be

toggle:
  -platform: gpio
    pin: 25
    id:relay
    name: "Gate Remote"
    icon: "mdi:gate"
    on_turn_on:
    - delay: 500ms
    - switch.turn_off: relay

I have tried to adapt it to my configuration for relay 1 of the KC868-A8 board.

switch:
  - platform: gpio
    name: "a8-garaje_rele_1"
    pin:
      pcf8574: pcf8574_hub_out_1
      number: 0
      mode: OUTPUT
      inverted: true
      on_turn_on:
        - delay: 500ms
        - switch.turn_off: relay

but I can't get rid of the error "on_turn_on" is an invalid option for Pin

Could you help me configure it?

Thanks in advance
