Garage cover template with ventilation (Hmip MOD_TM Novoferm)

Hi all,

i need your help how i can solve the following issue:
I have a Homematic-IP-ip MOD_TM Novoferm Garage component.
This is shown nice in HA as a cover.

The MOD_TM has also a ventilation state which i want to trigger via HA. This 3. Mode is not integrated in the cover(“component”)

So my idea was to write a own template in configuration.xml in order to trigger the ventilation state.
But the state ventilation is not avalable as a cover.
Do you have ideas how to sole this? Shoult i use a different template and if yes which on?

### HMIP MOD_TM  Garagentor ###########

  - platform: template
    covers:
        garagentor_links:
            friendly_name: "GaragentorLinks"
            value_template: "{{ is_state('sensor.XXXX_door_state', 'closed') }}"
            open_cover:
              service: homematic.set_device_value
              data:
                address: "<HOMEMATICSERIALNUMBER>"
                channel: 1
                param: DOOR_COMMAND
                value: 1
            close_cover:
              service: homematic.set_device_value
              data:
                address: "<HOMEMATICSERIALNUMBER>"

                channel: 1
                param: DOOR_COMMAND
                value: 3
            vent_cover:
              service: homematic.set_device_value
              data:
                address: "<HOMEMATICSERIALNUMBER>"
                channel: 1
