Integration is not working any more as WienerNetze API changed about wienernetzesmartmeter

[reox]

sounds like the /zaehlpunkt/default/welcome endpoint is gone...

Seems like it is split up now into several calls:
https://api.wstw.at/gateway/WN_SMART_METER_PORTAL_API_B2C/1.0/zaehlpunkt/consumptions returns:

{
    "consumptionYesterday": {
        "value": 3300,
        "validated": true,
        "date": "2023-02-15T23:00:00.000Z"
    },
    "consumptionDayBeforeYesterday": {
        "value": 4049,
        "validated": true,
        "date": "2023-02-14T23:00:00.000Z"
    }
}

and https://api.wstw.at/gateway/WN_SMART_METER_PORTAL_API_B2C/1.0/zaehlpunkt/baseInformation returns:

{
    "hasSmartMeter": true,
    "isDataDeleted": false,
    "dataDeletionTimestampUTC": null,
    "zaehlpunkt": {
        "zaehlpunktName": null,
        "zaehlpunktnummer": "...",
        "zaehlpunktAnlagentyp": "TAGSTROM",
        "adresse": "...",
        "postleitzahl": "..."
    }
}

there is also https://api.wstw.at/gateway/WN_SMART_METER_PORTAL_API_B2C/1.0/zaehlpunkt/meterReadings:

{
    "meterReadings": [
        {
            "value": 1234000,
            "type": "1-2:1.8.0",
            "validated": true,
            "date": "2023-02-16T23:00:00.000Z"
        }
    ]
}

IIRC these were the contents of the welcome endpoint before.

Fixed and rolled https://github.com/DarwinsBuddy/WienerNetzeSmartmeter/releases/tag/v1.0.2

same here, but with 2022.12.8, it seams like it‘s the API…

Hi, It's not working for me either.

Thanks @reox for investigating. Will have a look

@acdcnow Thanks a lot for reporting this in such a detailed manner and @reox for the quick analysis. :)
