Hallo,

I’m trying as described here [APIs · opendata-stuttgart/meta Wiki · GitHub](https://github.com/opendata-stuttgart/meta/wiki/APIs#ausf%C3%BChrlichere-beschreibung) to send data to [https://api-rrd.madavi.de/data.php](https://api-rrd.madavi.de/data.php)

Only data for temperature and humidity is shown, but no pressure and now dust values.

```auto
 curl -H "Content-Type: application/json" -H "X-Pin: 1" -H "X-Sensor: esp8266-XXXXX" --data data.json -X POST "https://api-rrd.madavi.de/data.php"

```

data.json

```auto
{
  "software_version": "your_version",
  "sensordatavalues":[
    {"value_type":"P1","value":"66.04"},
    {"value_type":"P2","value":"53.32"}
  ]
}

```

Return value is

```auto
Sensor: esp8266-XXXXX
ok

```

What am I doing wrong?

Posting the same to api.sensor.community/v1/push-sensor-data/ works, data is shown on the Live Map.

For [api-rrd.madavi.de](http://api-rrd.madavi.de) you need a prefix for the value\_type, i.e. ‘SDS\_’ for the SDS011 or ‘BME280\_’ for the BME280.  
You can see those prefixes in the source code of our firmware ([sensors-software/airrohr-firmware.ino at master · opendata-stuttgart/sensors-software · GitHub](https://github.com/opendata-stuttgart/sensors-software/blob/master/airrohr-firmware/airrohr-firmware.ino#L4423)).

Thanks, works now. Very confusing that this is not described on the API description. I’ve updated the Wikipage.
