Covers for Kitchen - zigbee 2way rele

Hi,
I’m working on automating my kitchen shutter using a zigbee controlled 2-way relay.
my idea is to maintain both manual and automatic control by inserting a rednode flow that checks the various states.
so far everything is ok.

Now, how can i have both open and close options active at the same time?
Because the shutter maybe half open or similar.

this my code:

kitchen2_window_cover:
      device_class: blind
      friendly_name: "kitchen Window Cover"
      open_cover:
        service: input_boolean.turn_on
        data:
          entity_id: input_boolean.kitchen_open_status
      close_cover:
        service: input_boolean.turn_on
        data:
          entity_id: input_boolean.kitchen_close_status
      stop_cover:
        service: input_boolean.turn_on
        data:
          entity_id: input_boolean.kitchen_stop_status

and this the lovelace result:

cards:
- type: custom:vertical-stack-in-card
  title: Tapparella 1
  cards:
    - type: entities
      entities:
        - entity: cover.kitchen2_window_cover
