Stepping MQTT cover slider on arrows action

Hello, not sure I post in the right place. I posted yesterday, but don’t see my post. So here it is again, sorry for messing up if I do.

I’m rather new to home Assistant and yaml stuff, so please be kind (and I’m not native english speaking neither).

I’m operating King Q4 covers using tasmota over MQTT on a PS-16-DZ module configuration. It does the job more or less, but the synchronization of the slider with the on/off commands. The slider has effect on the status open/closed, but the action to open or close doesn’t affect the slider at all.

Not ready to dive in the driver code, I’d like to have a dimmer action from home assistant in parallel with the open/close actions but I do not even find how to try that.

For instance, the action below:
payload_open: 'AT+UPDATE="sequence":"1576774195000","switch":"on"'

would ideally run an increment from 0 to 100 by steps of 5 every 5 seconds.

Any idea how I can do this ?

As info, the full configuration for each cover is like below:

cover Volet_Cheminee:
    platform: mqtt
    name: "volet cheminée"
    device_class: shade
    availability_topic: "tele/volet_cheminee/LWT"
    payload_available: "Connecté"
    payload_not_available: "Déconnecté"
    position_topic: "stat/volet_cheminee/position"
    position_open: 100
    position_closed: 0
    set_position_topic: "cmnd/volet_cheminee/Dimmer"
    command_topic: "cmnd/volet_cheminee/SerialSend2"
    payload_open: 'AT+UPDATE="sequence":"1576774195000","switch":"on"'
    payload_close: 'AT+UPDATE="sequence":"1576774195000","switch":"off"'
    payload_stop: 'AT+UPDATE="sequence":"1576774195000","switch":"pause"'
    retain: true
    optimistic: false
    qos: 1

I can run a list of my covers by the position, to operate like a group, but one by one, i’d like the arrows to influence de slider anyway.

    - platform: template
      switches:
        rez_de_chaussee:
          value_template: "{{ is_state('cover.Volet_Bureau', 'open') }}"
          turn_on:
            service: cover.set_cover_position
            data:
              entity_id: cover.Volet_Bureau, cover.Volet_Cheminee, cover.Volet_TV, cover.Volet_Salle_Manger
              position: 100
          turn_off:
            service: cover.set_cover_position
            data:
              entity_id: cover.Volet_Bureau, cover.Volet_Cheminee, cover.Volet_TV, cover.Volet_Salle_Manger
              position: 0
          icon_template: >-
            {% if is_state('switch.rez_de_chaussee', 'on') %}
              mdi:format-vertical-align-bottom
            {% else %}
              mdi:format-vertical-align-top
            {% endif %}

Any suggestion for the step increment from 0 to 100 every 5 seconds would be very much appreciated.

Have a nice day.
