Set Shelly PLUS 2PM position with a template

Configuration
1

I can set the position of a blind with the standaard automation configuration. Then I have this YAML:
alias: Aansturing klep vloerverwarming woonkamer
description: “”
trigger:

  • platform: state
    entity_id:
    • sensor.buitentemperatuur_2
  • platform: state
    entity_id:
    • sensor.gemetentemp
      condition:
      action:
  • device_id: 39926e5297676209a5065c79e6bead89
    domain: cover
    entity_id: 43747f9bd37705e8fd0baa03a02b82b0
    type: set_position
    position: 31
    mode: single

I can set the postion between 0 and 100 and that works fine.

I only want to set the position of the blinds via en template value, but when I put an template after postition like:
position: '“{{states(‘sensor.buitentemperatuur’) | float }}”

I get the following error:
Message malformed: value must be one of [‘close’, ‘close_tilt’, ‘open’, ‘open_tilt’, ‘stop’] for dictionary value @ data[‘type’]

Can anyone teell me what I am doing wrong.
