Shelly pro "Schätzgeräte" (pro 3em, pro em50) liefern Fequenz nur mit 1 Nachkommastelle. Voll doof.

openDTU onbattery hat Frequenz ausm WR mit 2 Nachkommastellen. Müsste man doch mim http get auslesen können? Aber dazu ist die doku zu sparsam oder ich habs überlesen?

2

müsste doch einen json File geben oder?

3

und wo ist frequenz?

oh nich gesehn muss ich mal mit rumspieln

habe mal chatGPT gefragt

Nur den Zahlenwert in Hz abrufen (benötigt jq):

curl -fsS 'http://192.168.10.10/api/livedata/status?inv=1161716xxxxx' \
  | jq '.inverters[0].AC["0"].Frequency.v'

Beispielausgabe: 50.02

Als kleines JSON mit Wert und Einheit:

curl -fsS 'http://192.168.10.10/api/livedata/status?inv=1161716xxxxx' \
  | jq '{netzfrequenz: .inverters[0].AC["0"].Frequency.v, einheit: .inverters[0].AC["0"].Frequency.u}'

Beispielausgabe:

{
  "netzfrequenz": 50.02,
  "einheit": "Hz"
}
