Coding issue for tests in speech system!

Configuration
1

Hi

I’m implementing snips in my system to control and interact with voice for HA and have already done light control and now doing température question. I want to be able to select the temperature zone I want and so I have to make a selection in HA to know which zone was requested if any and talk back correct answer.
I tried something like that for a first test but it’s already wrong for syntax but can’t figure out what’s wrong ? or perhaps not possible this way ?

intent_script:
  Temperature:
    speech:
      type: plain
      text: "'Il fait', {{ states('sensor.{% if lieu == "Grenoble" %}grenoble_temperature{% endif %}') | round(0)}}, 'degrés'"

I was thinking to do in a similar way I did for lights zones:

  Allumage_Lumiere:
    speech:
      type: plain
      text: "{{(['Ok,','cet fait,','Bien sur,','Comme vous voulez,','Si tu insistes,','Comme tu veux,','A vos souhaits,','A votre bon vouloir,','ainsi soit-il,','A vos ordres,','Pas de problème,','Bien sur votre grandeur,']|random)}}"
    action:
      - service: switch.turn_on
        data_template:
          entity_id: switch.{% if site_id == "salon" %}salon_suspension{% elif site_id == "sdb" %}sdb_lumiere_2{% elif site_id == "cuisine" %}cuisine_plafonnier{% endif %}
  Extinction_Lumiere:
    speech:
      type: plain
      text: "{{(['Ok,','cet fait,','Bien sur,','Comme vous voulez,','Si tu insistes,','Comme tu veux,','A vos souhaits,','A votre bon vouloir,','ainsi soit-il,','A vos ordres,','Pas de problème,','Bien sur votre grandeur,']|random)}}"
    action:
      - service: switch.turn_off
        data_template:
          entity_id: switch.{% if site_id == "salon" %}salon_suspension{% elif site_id == "sdb" %}sdb_lumiere_2{% elif site_id == "cuisine" %}cuisine_plafonnier{% endif %}

Thanks
