[SOLVED] HTTP-Binding errors from JSONPATH with Cache-Item

Sorry Vincent, I forgot to say, when using the api https://api.openweathermap.org/data/2.5/weather?id=1234567&APPID=my_key-1-32&lang=de&units=metric
i get this

{

    "coord": {
        "lon": 9.00,
        "lat": 48.00
    },
    "weather": [
        {
            "id": 800,
            "main": "Clear",
            "description": "Klarer Himmel",
            "icon": "01d"
        }
    ],

I found your post to UoM here
https://community.openhab.org/t/list-of-units-in-the-uom-unit-of-measurement/46842/6?u=fibu-freak

and understand what is meant with Number:Temperature Test_1 "Test1 [%.1f K]"
Thanks again
