Json, ApexCharts and correct time conversion

Third party integrations

Dear all,
I managed to extract the power generation data of my inverter from the online json file and put it into a sensor by using rest:

    - name: ABB_Aurora_graph_today
      unique_id: sensor.abb_aurora_graph_today
      value_template: "{{ (value_json.timestamp) }}"
      json_attributes_path: "$.fields[1]"
      json_attributes:
        - values

Looking at the developer tools → states I see the result is a sensor with Attributes:

values: 
- start: 1733034600
  startLabel: '20241201073000'
- start: 1733035500
  startLabel: '20241201074500'
  value: '12.957703590393'
- start: 1733036400
  startLabel: '20241201080000'
  value: '23.511345863342'

I have shown just a few values as example, as you can see at the beginning I only have the timestamp (start) and the same date in string format (startLabel), then whan the inverter starts to generate power I also have the power value (value).

I would like to plot this in a chart, installed Apex card but now I’m stuck not understanding how I can get/convert those data into Apex…

Tried with the non-working:

type: custom:apexcharts-card
header:
  title: Oggi
  show: true
  floating: false
  show_states: true
  colorize_states: true
span:
  start: day
series:
  - entity: sensor.abb_aurora_graph_today
    name: Potenza
    type: area
    stroke_width: 2
    data_generator: |
      return entity.attributes.values.map((entry) => {
        return [moment(entry.start).unix(), entry.value];
      });

can somebody help?
Thx

This would work

    data_generator: |
      return entity.attributes.values.map((entry) => {
        return [moment.unix(entry.start), entry.value];
      });

BUT… your first entry does not have a value so you have to tweak the generator to do something with that.
