Validating my template sensor

I’m trying to create a template sensor to extract weather forecast data, and I can’t seem to get the actual sensor values anywhere.

What I want is to have sensor.forecast_data with the attributes described below available at all times and updated once an hour.

My template sensor looks like this:

  - trigger:
      - platform: time_pattern
        hours: "/1"
      - service: weather.get_forecasts
          type: daily
          entity_id: weather.home
        response_variable: daily
      - name: Weatherman Data
        unique_id: forecast_data
        state: "{{ now().isoformat() }}"
          weather_condition_0: >
            {{ daily["weather.home"].forecast[0].condition }}
          weather_temperature_0: >
            {{  daily["weather.home"].forecast[0].temperature | round }}

However, this does not work; even after an hour, when the trigger fires, I cannot refer to sensor.forecast_data in any card or via esphome.

What am I doing wrong?

The entity_id of the Trigger-based Template Sensor you have created is sensor.weatherman_data
