@florian-h05 yep, but for a free service, I do not like or want to put my payment info there… that’s just the pure “for what” or data privacy question .. same is for the petrol binding or the public transportation..
creating ton’s of accounts for (at the end) a api, which is mostly totally public and does not require an api key?.. 
or at least, other providers do not require an key, but they deliver the same data..
I’m currently running on v4.1.1 .. the chart stuff would be my next topic, after it would work.. so if you put a tutorial, also I would be already very thankful 
found some 10 min’s today, currently now struggling with the JSONPATH query..
Would like to put a full day into a channel, but
Type string : forecast0 [
mode = "READONLY",
stateTransformation = "JSONPATH:$.data[0].attributes.hourly[:2]"
]
results in:
20:55:31.633 [WARN ] [nternal.JSonPathTransformationService] - JsonPath expressions with more than one result are only supported for Boolean, Number and String data types, please adapt your selector. Result: [{"dateTime":"2024-04-30T22:00:00Z","temp":17.1,"tApparent":14.1,"symbol":"101","precipitation":0,"precipitationChance":0,"windSpeed":11.1,"windGusts":28.1,"windDirection":120.8,"pressure":1011,"humidity":46.5,"sunMinutes":0,"sunElevation":-24.5,"uvIndex":0,"snowCover":0,"snowFresh":0,"snowChance":0},{"dateTime":"2024-04-30T23:00:00Z","temp":17,"tApparent":13.7,"symbol":"101","precipitation":0,"precipitationChance":0,"windSpeed":14.8,"windGusts":21.5,"windDirection":124.1,"pressure":1011,"humidity":50.7,"sunMinutes":0,"sunElevation":-26.1,"uvIndex":0,"snowCover":0,"snowFresh":0,"snowChance":0}]
I do not rlly understand the error message.. i’m selecting a array into a string.. for string it should be supported… so…
edit:
just found some post from rich..:
maybe I should also put each single value into an own channel in the thing already..
hmm…
