Figure out how to read inverter live data from zcsazzurro

[zmoog]

I own a zcsazzurro inverter connected to my solar panels. I want to collect live metrics from the zcs azzurro cloud.

API keys

• installed the app https://apps.apple.com/it/app/azzurro-operators/id6447290301?l=en-GB
• created a support ticket asking for API keys
• received the API keys in less that two business days (fair)

A quick test using cURL:

export ZCS_ENDPOINT="https://third.zcsazzurroportal.com:19003"
export ZCS_CLIENT_ID="<redacted>"
export ZCS_CLIENT_API_AUTH="<redacted>"

$ cat request.json 
{
    "realtimeData": {
        "command": "realtimeData",
        "params": {
            "thingKey": "SERIALNUMBER123",
            "requiredValues": "*"
        }
    }
}

$ curl -X POST "${ZCS_ENDPOINT}" \
    -H "Client:${ZCS_CLIENT_ID}" \
    -H "Authorization:${ZCS_CLIENT_API_AUTH}" \
    -d @request.json | jq    
{
  "realtimeData": {
    "params": {
      "value": [
        {
          "SERIALNUMBER123": {
            "powerCharging": 0,
            "batteryCycletime": 61,

          }
        }
      ]
    },

To make sense of these fields, here's the sample response and a screenshot from the app:

{
  "realtimeData": {
    "params": {
      "value": [
        {
          "123456789010": {
            "energyDischargingTotal": 739.8,
            "powerExporting": 0,
            "energyExportingTotal": 1327.9,
            "energyDischarging": 8.13,
            "batteryCycletime": 62,
            "lastUpdate": "2024-10-22T20:07:21Z",
            "energyGenerating": 20.46,

Note: The metrics are updated roughly every 5 minutes. Sometimes they stop updating for hours ¯_(ツ)_/¯

The prototype zmoog/otel-collector-contrib#7 is up and running.

Here's the initial dashboard:

[zmoog]

Sometimes, the metrics from the endpoint https://third.zcsazzurroportal.com:19003 stop updating, and the endpoint returns the last update. For example,

{
  "realtimeData": {
    "params": {
      "value": [
        {
          "123456789010": {
            "energyDischargingTotal": 739.8,
            "powerExporting": 0,
            "energyExportingTotal": 1327.9,
            "energyDischarging": 8.13,
            "batteryCycletime": 62,
            "lastUpdate": "2024-10-22T20:07:21Z",
            "energyGenerating": 20.46,
            "energyAutoconsumingTotal": 1130.3,
            "energyImporting": 4.0,
            "energyCharging": 4.67,
            "powerImporting": 880,
            "energyChargingTotal": 807.0,
            "energyConsumingTotal": 2100.2,
            "energyAutoconsuming": 15.61,
            "powerConsuming": 885,
            "energyConsuming": 27.74,
            "powerGenerating": 0,
            "energyImportingTotal": 546.1,
            "energyExporting": 0.18,
            "batterySoC": 20,
            "thingFind": "2024-06-04T08:55:36Z",
            "powerAutoconsuming": 0,
            "powerCharging": 0,
            "energyGeneratingTotal": 3265.2,
            "powerDischarging": 5
          }
        }
      ]
    },
    "success": true
  }
}

Right now, the endpoint returns an empty response:

{
  "realtimeData": {
    "params": {
      "value": [
        {
          "123456789010": {}
        }
      ]
    },
    "success": true
  }
}
