Toggle rollershutter with Xiaomi wireless switch

Hi all. I have a Fibaro FGM-222 rollershutter and I would like to control it with a Xiaomi wireless switch.

The easiest way would be if there is a cover.toggle like a switch.toggle.

Because its not there i want to do it with 3 automations.

If WirelessSwitch = click
condition: rollershutter current_position = 0 (means its closed)

The problem is the condition: How can i check the current_position?

Right now i have this:

- action:
  - data:
      entity_id: cover.fibaro_system_fgrm222_roller_shutter_controller_2_level_2
    service: cover.open_cover
  alias: Rollladen ist zu 0
  condition: []
  id: '1516293164675'
  - event_data:
      click_type: single
      entity_id: binary_sensor.switch_158d00012433dc
    event_type: click
    platform: event
