luftdaten "nested" json [Solved]

[svde]

I'm following https://www.domoticz.com/wiki/DzVents:_ ... ling_2.4.0 and trying to get data out of my luftdaten.info sensor. It gives back the http response and I can get data out of the top json values (like software_version and age), but how do I get to the nested ones (like the value of SDS_P1?

JSON response is:

Code: Select all

{
  "software_version": "NRZ-2017-099",
  "age": "104",
  "sensordatavalues": [
    {
      "value_type": "SDS_P1",
      "value": "13.37"
    },
    {
      "value_type": "SDS_P2",
      "value": "11.23"
    },
    {
      "value_type": "temperature",
      "value": "19.10"
    },
    {
      "value_type": "humidity",
      "value": "54.00"
    },
    {
      "value_type": "BME280_temperature",
      "value": "23.80"
    },
    {
      "value_type": "BME280_humidity",
      "value": "38.49"
    },
    {
      "value_type": "BME280_pressure",
      "value": "100476.89"
    },
    {
      "value_type": "samples",
      "value": "589419"
    },
    {
      "value_type": "min_micro",
      "value": "243"
    },
    {
      "value_type": "max_micro",
      "value": "26699"
    },
    {
      "value_type": "signal",
      "value": "-60"
    }
  ]
}

For the moment I'm logging these:

Code: Select all

domoticz.log(item.json.software_version)
domoticz.log(item.json.age)
domoticz.log(item.json.sensordatavalues)

which shows up as:

Code: Select all

It is an indexed table so you can do it like this:
item.json.sensorvalues[1].value
