Qcells / Solax Pv Anlage live Datenabfrage via Curl

jamakr4

Hallo,
alle die eine Solax bzw Qcells Pv Anlage haben kennen bestimmt das Problem, dass die Daten welche man über die Cloud bekommt nur alle 5 Minuten aktualisiert werden. Das ist für meine Zwecke jedoch zu ungenau. Also kurz gesucht und siehe da es gibt eine Lösung welche wesentlich mehr Daten in einem wesentlich kürzeren Zeitintervall ausgibt:

curl -d "optType=ReadRealTimeData&pwd=<XXX Passwort XXX>" http://<XXX IP Adresse XXX>

Als Folge kommt dann dieses tolle Zahlen Chaos (wahrscheinlich in json) raus:

{"sn":"XXXXXXXX","ver":"3.008.10","type":14,"Data":[2342,2297,2364,55,54,54,1269,1229,1268,3766,4949,3130,21,91,1067,2852,4996,5000,4998,2,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1341,0,0,0,0,42780,0,0,4262,0,0,1,49,2425,256,7685,6672,5893,100,0,42,0,0,0,0,0,0,0,0,0,0,0,0,0,11156,0,385,4,0,0,2833,0,3235,0,31,100,12045,0,471,0,0,0,44032,0,16875,0,2755,0,220,0,0,0,0,0,0,0,0,0,1,99,1,32,122,256,4672,3200,0,300,242,218,34,33,24,2132,782,15934,15934,15934,15934,0,0,3358,3321,44242,9,20564,12339,18753,12599,18737,12356,14132,20564,12339,18754,12345,18742,12358,12599,20564,12339,18754,12345,18742,12870,14132,20564,12339,18754,12345,18742,12870,12338,20564,12339,18754,12345,18742,12358,13110,4097,4098,1281,259,0,42780,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"Information":[XXXXXX,XXX,"XXXXXXXXXXX",8,1.30,0.00,1.28,1.09,0.00,1]}

Auf Github hat jemand die Zahlen dann mit diesem Skript auseinander gepuzzelt (welcher Wert bedeutet was)

Nun ist meine Idee die Werte aus der Curl Abfrage einfach in ioBroker Datenpunkte einzutragen, leider kenne ich mich mit der Materie noch zu wenig aus und wollte daher mal fragen ob eventuell hier jemand eine Idee hat.

Viele Grüße

@jamakr4 schau dir axios mal an..damit kannst du den curl absetzen und die daten empfangen..
dann musst du den json zerlegen..

@jamakr4

Ich arbeite mit dem Solax Adapter und kann damit die Daten lokal z. B. im 10-Sekundentakt abfragen. Die cloud benötige ich gar nicht.

@meister-mopper Danke

evtl. nützt es dir was.
