GPIO momentary switch and interlock issue

1

Hello to the community,

I have an issue, by combining momentary switches and interlock feature.

Momentary switches work individually like a charm (on => 1000ms delay => off)

When using interlock, momentary switches are triggered sequentially as expected, but duration is very quick (100ms ? 200 ms ?) instead of awaited 1000ms.

Is this a known issue ? Should I adopt another approach ?

Here is more detail about my project :

I want to manage 8 roller shutters with ESPHome using the dry contacts of the remote controls.

So I used the “cover” component with 24 gpio “switch” (8 remote controls x 3 buttons)

Orders must never be sent at the same time, but sequentially.

Each command must last about 750ms to be correctly taken into account by rolling shutters (I use 1000ms)

Here is the cover YAML for one remote control :

cover:
  - platform: time_based
    name: "Salon Est"
    # 
    open_action:
      - switch.turn_on: salon_est_up
      - delay: 1s
      - switch.turn_off: salon_est_up
    open_duration: 28s
    # 
    stop_action:
      - switch.turn_on: salon_est_stop
      - delay: 1s
      - switch.turn_off: salon_est_stop
    # 
    close_action:
      - switch.turn_on: salon_est_down
      - delay: 1s
      - switch.turn_off: salon_est_down
    close_duration: 28s

And the linked switch (ou can see that interlock targets all switches) :

switch:
  #
  # Salon Est
  #
  - platform: gpio
    name: "Salon Est - Monter (contact)"
    id: salon_est_up
    internal: true
    interlock: &interlock_group [salon_est_up, salon_est_stop, salon_est_down, salon_sud_est_up, salon_sud_est_stop, salon_sud_est_down,salon_sud_ouest_up, salon_sud_ouest_stop, salon_sud_ouest_down, cuisine_up, cuisine_stop, cuisine_down, bureau_up, bureau_stop, bureau_down, tictac_up, tictac_stop, tictac_down, dialyse_up, dialyse_stop, dialyse_down, chambre_up, chambre_stop, chambre_down]
    pin:
      pcf8574: pcf8574_1_hub
      number: 3
      mode: OUTPUT
      inverted: False
  - platform: gpio
    name: "Salon Est - Stopper (contact)"
    id: salon_est_stop
    internal: true
    interlock: *interlock_group    
    pin:
      pcf8574: pcf8574_1_hub
      number: 2
      mode: OUTPUT
      inverted: False
  - platform: gpio
    name: "Salon Est - Descendre (contact)"
    id: salon_est_down
    internal: true
    interlock: *interlock_group    
    pin:
      pcf8574: pcf8574_1_hub
      number: 0
      mode: OUTPUT
      inverted: False

Thank you for your help.
