Wunderground example

The Wunderground API delivers simple JSON as response.

Therefor we can use a JSON based grouping channel to store sesveral readings.

Request

Example request:

http://api.wunderground.com/api/<your_key>/conditions/lang:DL/q/51.548203,12.131052.json

Result

Channel settings

We need here for example the path to the temperature in °C (temp_c), so store the channel as this:

{
    ...
    "current_observation": {
        ...
        "temp_c":10,
        ...
    }
}

PVLng have a pre-defined channel type Wunderground, a template and a script for this.
