Getting forecast temperature from the weather.openweathermap forecast array

Configuration
, ,
1

In the past I could use this to get the forecast temperature for the day, but that returns a ‘null’ now (note: I’m using a template to get the values):

{{state_attr('weather.openweathermap', 'forecast')}}

In the integration I see a array with forecast and multiple hourly temperatures, but how can I access this? Like this:

Maybe it has something to do with the legacy forecast that was removed here: Remove deprecated forecast attribute from WeatherEntity (#110761) · home-assistant/core@6523090 · GitHub

Or the issues with the configuration itself here: OpenWeatherMap only works on Hourly · Issue #114508 · home-assistant/core · GitHub

Any thoughts?

yes, that method is deprecated.

you need to use get_forecast to fetch it now.

example for how here:

I’m using the daily forecast from OpenWeatherMap, but maybe this will help get you pointed in the right direction.

- trigger:
    - platform: time_pattern
      hours: /1
    - platform: homeassistant
      event: start
  action:
    - service: weather.get_forecasts
      data:
        type: daily
      target:
        entity_id: weather.openweathermap
      response_variable: response
  sensor:
    - name: Weather Forecast
      unique_id: 0a7476cc-d6c1-40ba-8ae1-606518c3497a
      state: "{{ now().isoformat() }}"
      attributes:
        forecast: "{{ response['weather.openweathermap'].forecast }}"
    - name: Today High
      device_class: Temperature
      unit_of_measurement: °F
      icon: mdi:thermometer-high
      state: "{{ response['weather.openweathermap'].forecast[0].temperature }}"
    - name: Today Low
      device_class: Temperature
      unit_of_measurement: °F
      icon: mdi:thermometer-low
      state: "{{ response['weather.openweathermap'].forecast[0].templow }}"

Thanks for the pointer, adjusted my automation and works like a charm again

Thanks for the code! I got it working like a charm again.
My code is a bit different, I’m getting the first eight hours of temperature. Maybe it helps someone:

{%- for _ in range(8) -%}
      {%- set values = {
        "time": as_timestamp(response['weather.openweathermap'].forecast[loop.index0].datetime) | timestamp_custom("%H:%M"),
        "temperature": response['weather.openweathermap'].forecast[loop.index0].temperature,
        "condition": response['weather.openweathermap'].forecast[loop.index0].condition,
        "cloud_coverage": response['weather.openweathermap'].forecast[loop.index0].cloud_coverage,
        "humidity": response['weather.openweathermap'].forecast[loop.index0].humidity
      } %}
    {% if values.time %}🕗 {{ values.time }}{% endif %},

    {%- if values.temperature <5 %} ❄️{% elif values.temperature <0 %} ☃️{% else %} 🌡️{% endif %} {{ values.temperature }},

    {%- if values.condition == 'rainy' %} 🌧️{% elif values.condition ==
    'cloudy' %} ☁️{% elif values.condition == 'partlycloudy' %} ⛅{% elif
    values.condition == 'clear-night' %} 🌑{% else %} ☀️{% endif %} {{
    values.condition }},

    {%- if values.cloud_coverage %} ☁️ {{ values.cloud_coverage }}%{% endif %}, 

    {%- if values.humidity %}💧 {{ values.humidity }}%{% endif %}

    {%- endfor %}

Bit shorter:

{%- {'rainy':'🌧️','cloudy':'☁️','partlycloudy':'⛅','clear-night':'🌑'}.get(values.condition,'☀️') %}

Hah that’s a better way to do it, thanks!

Hi Marck,

Ik like this approach a lot, but, where do i add this when i take for example the configuration of pkscout?

Many thanks in advance!
