Maximum temperature of Met.no

Configuration
20

Sorry can i ask you a question about this.

My implementation

is basically the same but the “daily” forecast for today (i also pull from *.forecast[0]) seems to be very inconsistent and very low in the morning and very high at noon, for Example:

  • get_forecast at 1am: temperature = 17°C
  • get_forecast at 5pm: temperature = 23°C

I would have expected the daily forecast to give me (nearly) the same values throughout the whole day but this seems to change drastically

I always try to gather todays max temperature at 1am in the morning to de/activate all automations related to todays temperature

So my current guess is, that this is not the max temperature of the day, but some sort of mean temperature?

What i will check next

  • Get an hourly forecast
  • Extract the max temperature of the coming 24 values/hours

Taken from the examples above (AND NOT YET TESTED) i think about something like this:

template:
  - trigger:
      - platform: time_pattern
        hours: /1
      - platform: event
        event_type: event_template_reloaded
    action:
      - variables:
          w: weather.home
      - service: weather.get_forecasts
        data:
          type: hourly
        target:
          entity_id: '{{ w }}'
        response_variable: r
    sensor:
      - name: 'Temperature Max'
        unique_id: 'temperature_max'
        unit_of_measurement: '°C'
        device_class: temperature
        state: >
          {{ r[w].forecast[:24] | map(attribute='temperature')
            | reject('string') | max }}

My Question

So my basic question is, what exactly did i not understand about the daily forecast of met.no. I am guessing that i did not understand what daily forecast[0] really is

Thank you

EDIT:

From what i saw here : Definitive guide to Weather integrations :sun_behind_rain_cloud: - Community Guides - Home Assistant Community
The met.no service anyways returns only 24 values for a whole day

So i can use the unchanged example (without [:24]) and will get my expected result.

I think the bottomline is:

Use the HOURLY weather report to get the DAILY max-temp as posted above
This was what confused me in the first place i think

See the quote above? The HOURLY weather forecast is used, but the temperature_max returned is DAILY

Am i right?
