Describe the bug

This is the template I'm using under configuration.yaml:

template:
  - trigger:
      - platform: time
        at: "00:00:01"
      - platform: homeassistant
        event: start
      - platform: event
        event_type: event_template_reloaded
    action:
      - service: weather.get_forecast
        data:
          type: daily
        target:
          entity_id: weather.bad_homburg_wetterstation
        response_variable: weather_data
    sensor:
      - name: "Max temp Bad Homburg heute (DWD)"
        unique_id: max_daily_temp
        state: >-
          {{ weather_data.forecast[0].temperature }}
        unit_of_measurement: "°C"

I restarted HA which should've triggered the sensor, but there's no value.

Is there any value after some time?

I assume your template is missing some key for the weather_data response variable.

Example from weather integration documentation.

template:
  - trigger:
      - platform: time_pattern
        hours: /1
    action:
      - action: weather.get_forecasts
        data:
          type: hourly
        target:
          entity_id: weather.home
        response_variable: hourly
    sensor:
      - name: Temperature forecast next hour
        unique_id: temperature_forecast_next_hour
        state: "{{ hourly['weather.home'].forecast[0].temperature }}"
        unit_of_measurement: °C

I assume you need something like {{ weather_data['weather.bad_homburg_wetterstation'].forecast[0].temperature }}

no

I assume your template is missing some key for the weather_data response variable.

what key though?

I assume you need something like {{ weather_data['weather.bad_homburg_wetterstation'].forecast[0].temperature }}

I put this as the state and the sensor still reports unknown, even after 1 day.

@ars4l4n I've found two errors in your configuration. I marked them in bold:

template:

• trigger:
  • platform: time at: "00:00:01"
  • platform: homeassistant event: start
  • platform: event event_type: event_template_reloaded action:
  • service: weather.get_forecasts data: type: daily target: entity_id: weather.bad_homburg_wetterstation response_variable: weather_data sensor:
  • name: "Max temp Bad Homburg heute (DWD)" unique_id: max_daily_temp state: >- {{ weather_data ['weather.bad_homburg_wetterstation'].forecast[0].temperature }} unit_of_measurement: "°C"

The first was missing an 's' and the second was missing the key of the weather station. With this everything should work as expected.

@ars4l4n Were you able to resolve your issue?

I'll close this for now. Feel free to reopen if you still need assistance.
