RESTful sensor to show solarpanel data in graph

Configuration
1

I am trying to retrieve data from my solar panels with a RESTful sensor. I want to show the montly production from the past year in a graph.
The api gave me these results:

{
    "energy": {
        "timeUnit": "MONTH",
        "unit": "Wh",
        "measuredBy": "INVERTER",
        "values": [
            {
                "date": "2020-01-01 00:00:00",
                "value": 77742.0
            }, {
                "date": "2020-02-01 00:00:00",
                "value": 149768.0
            }, {
                "date": "2020-03-01 00:00:00",
                "value": 462802.0
            }, {
                "date": "2020-04-01 00:00:00",
                "value": 679417.0
            }, {
                "date": "2020-05-01 00:00:00",
                "value": 792385.0
            }, {
                "date": "2020-06-01 00:00:00",
                "value": 727016.0
            }, {
                "date": "2020-07-01 00:00:00",
                "value": 613442.0
            }, {
                "date": "2020-08-01 00:00:00",
                "value": 576991.0
            }, {
                "date": "2020-09-01 00:00:00",
                "value": 470422.0
            }, {
                "date": "2020-10-01 00:00:00",
                "value": 148939.0
            }, {
                "date": "2020-11-01 00:00:00",
                "value": null
            }, {
                "date": "2020-12-01 00:00:00",
                "value": null
            }
        ]
    }
}

And this is the configuration i use:

  - platform: rest
    name: solaredge_data
    resource: https://<URL>
    
  - platform: template
    sensors:
      production_per_month:
        value_template: '{{ states.sensor.solaredge_data.attributes["energy"]["values"] }}'
        unit_of_measurement: 'Wh'

I have spent several hours to get it to work and from the documentation I can’t figure out how to do it. Any help would be appreciated
