Daten aus Url abfragen und in Datenpunkt schreiben

[keksn]

Hallo, ich versuche gerade aus einer Url einen Datenpunkt zu beschreiben.(Strompreis) Leider mache ich da was falsch. Ich habe mich einer alten Anleitung von paul53 bedient. Jedoch stimmt da was bei der Attributsabfrage nicht.

Danke vorab für die Lösung!

@keksn was kommt denn da als result beim request?
kannst du über einen debug Baustein auswerfen

edit
es muss result und nicht Result heissen

@keksn
Die API liefert unter "data" eine Liste mit 192 Objekten, beginnend heute um 0:00 Uhr für alle 15 Minuten. Es muss also ganz anders gehandhabt werden.

Sollen 192 Datenpunkte befüllt werden?

@paul53

Ich habe das jetzt genau so nachgebaut. Wie schreibe ich jetzt in meinem Datenpunkt?

[Homoran]

@keksn sagte in Daten aus Url abfragen und in Datenpunkt schreiben:

Du erwartest Dir ein wenig zu viel

OK, in diesem Fall ist es etwas komplexer.
Dadurch dass du den richtigen Eintrag über seine Nummer suchen und diese über die aktuelle Zeit ausrechnen musst.

Prinzipiell schnappst du dir so ein JSON, das der result liefert und kopierst es in die folgende Website

Dort wird dir die Struktur angezeigt, mit der du den gewünschten Wert erhältst.

hier leider 191 Viertelstunden, die nur über die laufende Nummer zu erreichen sind.

in den Datenpunkt schreibst du wie gehabt, anstelle des debug

[keksn]

@paul53 a ok, ich habe den Datenpunkt mit dem idx aktualisiert. Was muss ich noch umbauen dass ich nur den Wert ohne Datum und Uhrzeit in den Datenpunkt schreibe kann?

[paul53]

@keksn sagte: Wie schreibe ich jetzt in meinem Datenpunkt?

Anstelle von "debug" nimm "aktualisiere". Das Attribut "value" separiert den Preis.
