Hallo!

Ich versuche verzweifelt mit der Apexchart-card mittels data_generator Daten darzustellen.
Die Daten kommen aus dem Awattar Adapter im JSON Format.

Hier im Forum hat es @copystring schon geschafft zukünftige Daten auf dem PV-Forecast Adapter darzustellen. (https://forum.iobroker.net/topic/45315/test-pv-forecast-adapter/440?_=1719822087869)

Die Daten aus dem Awattar Adapter sehen so aus:

Meine Versuche den Code von @copystring an das o.g. JSON anzupassen, schlugen leider alle fehl.
zB

type: custom:apexcharts-card
graph_span: 2d
span:
  start: day
series:
  - entity: sensor.awattar_full
    type: column
    data_generator: |
      var data = [];
      var formattedJSON = JSON.parse(entity.state);
      console.log(formattedJSON);
      formattedJSON.forEach(obj => {
        data.push([obj.start_timestamp, obj.marketprice])
      });
      return data;

In der js console kommt dann immer der Fehler 'Error: formattedJSON.forEach is not a function'

Ich bin mir fast sicher das ich nur eine Kleinigkeit falsch mache.
Kann mir jemand weiterhelfen?

Schöne Grüße!

@fhainz sagte: Die Daten aus dem Awattar Adapter sehen so aus:

Die Schleife muss über ein Array laufen. Ändere mal Zeile 10 in

      var formattedJSON = JSON.parse(entity.state).data;
