Bei mir läuft die node Version 18.17.0
Der aktuelle Code sieht so aus:
/* Meteohub
Skript holt Daten aus Meteohub XML Datei, bereitet sie auf und stellt einige Datenpunkte zur Verfügung
erstellt: 2020 Wolfgang Berger
{1}
V 0.1 Initiale Version. Hartcodierte Zuordnung. Wird nicht funktionieren sobald der Windmesser online ist.
V 0.2 jetzt Sensoren in Liste
V 0.3 kosmetische Aufbereitung. Altlasten entfernt.

Ursprünglich war es der Code aus dem Post und die Zeile für den Datenabruf:
const mh_URL = 'http://192.168.75.9/meteograph.cgi?text=allxml';
musste angepasst werden. Danach hatte ich das Problem, dass er wegen folgenden Fehler hatte:
20.7.2023, 21:05:08.838 [error]: javascript.0 (2129892) script.js.common.WetterdatenEinlesen: Fehler beim Herunterladen Meteohub XML: Error: Parse Error: Invalid header value char
@Homoran , @paul53 und @ticaki haben sich dann an vielen Dingen versucht, aber bisher ohne Erfolg 
allerdings schaffe ich es nicht, in den Datenpunkt eine Uhrzeit einzutragen.
