Voltoplus Integration, parse JSON response

Configuration Frontend
1

Hi,

I need some help on reading out/controlling my Voltoplus device. Everything can be done by GET and POST methods.

GET http://voltoplus.local/api/v1/values will return all values at once as JSON:

{
    "json_values": [
        {
            "id": "U1",
            "value": "0"
        },
        {
            "id": "U2",
            "value": "0"
        },
        {
            "id": "U3",
            "value": "0"
        },
        {
            "id": "I1",
            "value": "0"
        },
        {
            "id": "I2",
            "value": "0"
        },
        {
            "id": "I3",
            "value": "0"
        },
        {
            "id": "P1",
            "value": "0"
        },
        {
            "id": "P2",
            "value": "0"
        },
        {
            "id": "P3",
            "value": "0"
        },
        {
            "id": "P",
            "value": "0"
        },
        {
            "id": "fwdEn",
            "value": "62289"
        },
        {
            "id": "rvsEn",
            "value": "94225"
        },
        {
            "id": "AO1",
            "value": "43"
        },
        {
            "id": "AO2",
            "value": "56"
        },
        {
            "id": "my-PV1",
            "value": "0"
        },
        {
            "id": "abl1",
            "value": "0"
        },
        {
            "id": "DO1",
            "value": "0"
        },
        {
            "id": "DO2",
            "value": "0"
        },
        {
            "id": "LEDS",
            "value": "0"
        },
        {
            "id": "LEDP",
            "value": "0"
        },
        {
            "id": "date_time",
            "value": {
                "year": 2024,
                "month": 8,
                "day": 16,
                "hour": 13,
                "minute": 10,
                "second": 14
            }
        }
    ]
}

I tried different configuration like the following, but without success:

sensor:
  - platform: rest
    name: voltoplus_analog_out_1
    method: GET
    unit_of_measurement: "%"
    resource: http://voltoplus.local/api/v1/values
    value_template: "{{ value_json.json_values.id[AO1] }}"
    scan_interval: 30

And second:
what would be an easy solution to send POST’s like this:

{"json_config":[{"id":"210","value":"1"},{"id":"211","value":"50"},{"id":"212","value":"18:45"}]}

210: Activate manual mode
211: Set output to 50%
212: Go back to automatic mode at 18:45

thanks a lot in advance!

For the GET, I only know how to do this via command_line and a curl + jq
If the A01 is always at the same locaiton in the dict then you can use the dict posion between , e.g. json_values[12]
If not then … jq probably … Can help but maybe someone else has a better idea
