Can't get my configuration to work (required key 'platform' not provided) - what's my mistake/error?

Configuration
1

Hi guys,

I wanted to implement this great project in my Home Assistant: Google Weather Frog Card

Everything worked out fine so far, however, there is a minor issue that I can’t resolve. The code in the configuration.yaml looks like this:

sensor:
    - trigger:
        - platform: time_pattern
          minutes: "30"
        - platform: homeassistant
          event: start
        - platform: event
          event_type: event_template_reloaded
      action:
        - service: weather.get_forecasts
          target:
            entity_id: weather.hamburgairport 
          data:
            type: hourly
          response_variable: forecast
      sensor:
        - name: "Wetter_HamburgA_Niederschlagsmenge" 
          unique_id: wetter_hamburga_niederschlagsmenge
          state: >
            {{
              forecast['weather.hamburgairport'].forecast[0].precipitation
            }}

    - trigger:
        - platform: time_pattern
          hours: "1"
        - platform: homeassistant
          event: start
        - platform: event
          event_type: event_template_reloaded
      action:
        - service: weather.get_forecasts
          target:
            entity_id: weather.hamburgairport
          data:
            type: daily
          response_variable: forecast
      sensor:
        - name: "Wetter_HamburgA_Vorhersage_Status"
          unique_id: wetter_hamburga_vorhersage_status
          state: >
            {{
              forecast['weather.hamburgairport'].forecast[0].condition
            }}
    
        - name: "Wetter_HamburgA_Vorhersage_Temperatur"
          unique_id: wetter_HamburgA_vorhersage_temperatur
          unit_of_measurement: °C
          state: >
            {{
              forecast['weather.hamburgairport'].forecast[0].temperature 
            }}

The error that I get is as following:

Konfigurationswarnungen
Invalid config for 'sensor' at configuration.yaml, line 24: required key 'platform' not provided
Invalid config for 'sensor' at configuration.yaml, line 48: required key 'platform' not provided

What am I doing wrong?
Best regards,
Dennis

You created the configuration for a Trigger-based Template Sensor but placed it under the wrong key. You put in under sensor: but it belongs under template:

Refer to the example shown in the documentation. Notice how it uses the template: key.
