Integrate Hourly forecast in apex-charts after update to service.get_forecast

Configuration Frontend
1

Hi all,

after upgrading to the latest Home Assistant (from 2024.1.x to 2024.3.2), it seems that Meteorologisk institutt (Met.no) forecasts “lost” the hourly entity, which I used in apexcharts to draw the temperature for the next 24 hours. This information, if I understand it correctly, is now available by calling the service.get_forecast with hourly option (which works in the developer section nicely). But I have no idea, how I can retrieve it from within an apexcharts card or how to get the service data into an own entity or its attributes.

The code I used pefore looks like this:

  - entity: weather.homebw_hourly
    show:
      extremas: true
      offset_in_name: false
      legend_value: false
    float_precision: 1
    yaxis_id: outtemp
    stroke_width: 1
    color: green
    unit: °C
    group_by:
      fill: 'null'
    data_generator: |
      var now = new Date();
      var tdata = entity.attributes.forecast.map(
          (f) => {
            var ctime = new Date(f.datetime);
            return [ctime.getTime(), f.temperature];
          }        
        );
      tdata.unshift([now.getTime(), entity.attributes.temperature]);
      return tdata;

Any help is appreciated.

Regards,
Daniel

Did you figure this out? I have the same issue

This is wat I used: (slightly different)

data_generator: |
  return entity.attributes.forecast.map((entry) => {
        return [new Date(entry.datetime).getTime(), entry.temperature];
      });

Found a workaround.

  1. Create this template
  2. Note your original wwather entity is used twice
  3. After reboot a new sensor sensor.forecast_home_hourly is available
  4. Due to /1 time trigger, wait at least an hour to see it populated
  5. Use the new sensor.forecast_home_hourly in apex-chart
type: custom:apexcharts-card
