weather-chart-card From 2024.4.0, attributes.forecast will be removed

Starting this 3rd of April 2024, the new release of HA is no longer publishing the forecast as an attribute. The code accessing attributes.forecast must be replaced by a call the get_forecasts service:

Probably something like this.

  homeassistant.callService(weather, 'get_forecasts', {
    type: 'daily',
  }).then(function(response) {
    // Check that forecasts is in the answer
    if (!response || !response.forecasts) {
      console.error('No forecast data available');
      return;
    }

Otherwise the card will show

Please, check your weather entity

Unfortunately, as an old programmer, I'm not good enough in JS to change it myself in a fork.

I just updated to 2024.4.0 and as OToussaint said, the card no longer works.

You can create a template sensor to get the daily (and hourly) forecast. Here is my example for daily. It will create a new sensor which you can add to the card.

- trigger:
  - platform: time_pattern
    hours: /1
  - platform: homeassistant
    event: start
  action:
    - service: weather.get_forecasts
      data:
        type: daily
      target:
        entity_id: weather.forecast_gaszowice
      response_variable: daily
  sensor:
    - name: Forecast Gaszowice Daily
      state: "{{ states('weather.forecast_gaszowice') }}"
      attributes:
        temperature: "{{ state_attr('weather.forecast_gaszowice', 'temperature') }}"
        dew_point: "{{ state_attr('weather.forecast_gaszowice', 'dew_point') }}"
        temperature_unit: "{{ state_attr('weather.forecast_gaszowice', 'temperature_unit') }}"
        humidity: "{{ state_attr('weather.forecast_gaszowice', 'humidity') }}"
        cloud_coverage: "{{ state_attr('weather.forecast_gaszowice', 'cloud_coverage') }}"
        pressure: "{{ state_attr('weather.forecast_gaszowice', 'pressure') }}"
        pressure_unit: "{{ state_attr('weather.forecast_gaszowice', 'pressure_unit') }}"
        wind_bearing: "{{ state_attr('weather.forecast_gaszowice', 'wind_bearing') }}"
        wind_speed: "{{ state_attr('weather.forecast_gaszowice', 'wind_speed') }}"
        wind_speed_unit: "{{ state_attr('weather.forecast_gaszowice', 'wind_speed_unit') }}"
        visibility_unit: "{{ state_attr('weather.forecast_gaszowice', 'visibility_unit') }}"
        precipitation_unit: "{{ state_attr('weather.forecast_gaszowice', 'precipitation_unit') }}"
        forecast: "{{ daily['weather.forecast_gaszowice'].forecast }}"
