JsonMod Hilfe für komplexe readings

[uwirt]

Hallo - ich versuche aus einer API-Abfrage mittels JsonMod die Readings auszulesen (und wenn möglich dann auch noch von °F auf °C umzurechnen).

Das Json-File schaut wie folgt aus:

Ich hätte davon gerne als erstes den Wert für outdoor temperature: 66.4 (den ich dann in °C umrechnen möchte)

Mein attr readingList bisher:

Code Auswählen Erweitern

attr ecowitt readingList single(jsonPath('$.[temperature].[value]'), 'value', '-?-');funktionierte leider nicht.

JsonMod Hilfe für komplexe readings

Was ist denn daran bitteschön "komplex"?
Einfacher als in diesem Fall geht es doch kaum noch,

{"code":0,"msg":"success","time":"1722848586","data":{"outdoor":{"temperature":{"time":"1722848551","unit":"ºF","value":"66.4"}

man braucht nur abzuschreiben:

Code Auswählen Erweitern

readingList single (jsonPath('$.data.outdoor.temperature.value'),'value','-?-')

Und mit Konvertierung wird es auch nicht viel komplexer...

Code Auswählen Erweitern

readingList single (round((jsonPath('$.data.outdoor.temperature.value')-32)*5/9,1),'value','-?-')

Besten Dank - es funktioniert.

Nur noch eine weitere (nicht-komplexe) Frage zur Umrechnung:

Ich möchte dem Luftdruck von inHg in hPA umrechnen.

Das hier:

Code Auswählen Erweitern

readingList single (round(jsonPath('$.data.pressure.absolute.value')*33,8638815789),'hPA','-?-')
geht so leider nicht.

[rudolfkoenig]

33,8638815789 => 33.8638815789

[betateilchen]

geht so leider nicht.

das ist eine ziemlich unsinnige wenig hilfreiche Problembeschreibung...
Was genau funktioniert denn nicht?

Hast Du eigentlich verstanden, was Dein Funktionsaufruf:

Code Auswählen Erweitern

round( jsonPath('$.data.pressure.absolute.value')*33,8638815789 )
bewirkt bzw. tut?
Du gibst darin an, dass der aus jsonPath() ermittelte Wert mit 33 multipliziert werden soll.
Danach soll das Ergebnis auf 8638815789 Nachkommastellen gerundet werden...

Übrigens...

Falsch:

in hPA umrechnen

Richtig:

in hPa umrechnen
