IFTTT + Google Assistant with template entity_id

Configuration
1

Hi Guys, i’m trying to setup a IFTTT Applet to change the temperature of my thermostats in each room, I don’t want to have an Applet for every single room so I used the google assistant trigger with a word and a number variable on ifttt. Now I’m trying to setup a script with a template for the entity_id to assign the thermostat to a room. that’s what I came up with so far, but it is not working.

script:
  heizung:
    sequence:
      service: climate.set_temperature
      data_template:
        entity_id: >
          {% if (room == "Wohnzimmer") %}
            climate.keq0442360
          {% elif (room == "Schlafzimmer") %}
            climate.keq0440911
          {% endif %}
        temperature: '{{temperature}}'

Hi, did you ever manage to get this working? I am trying to do a similar thing but am stuck on the variables syntax.

Thanks.
