Ahoy DTU per JSON einbinden

Verfasst: Mi Apr 26, 2023 8:06 am

Ich habe einen Hoymiles 600 WR und mir auch schon eine Ahoy DTU zusammengebaut, die auch läuft und alle Werte anzeigt.
Ich habe auch gelesen, dass es möglich ist, diese per JSON direkt in die OpenWB einzulesen. Die in der entsprechenden Diskussion zur Open DTU angegebenen Werte funktionieren leider mit der Ahoy anscheinend nicht.
Ich bin ziemlicher Anfänger.
Kann jemand beschreiben, wie die Ahoy DTU korrekt per JSON in die OpenWB eingebunden werden kann?

Wie sieht denn das JSON aus und über welche URL kann es abgefragt werden? Um den Rest kümmert sich dann vermutlich Det. :D

Ist das gemeint:

Code: Alles auswählen

{"avail_endpoints":{"system":"http://192.168.188.77/api/system","statistics":"http://192.168.188.77/api/statistics","inverter/list":"http://192.168.188.77/api/inverter/list","index":"http://192.168.188.77/api/index","setup":"http://192.168.188.77/api/setup","live":"http://192.168.188.77/api/live","record/info":"http://192.168.188.77/api/record/info","record/alarm":"http://192.168.188.77/api/record/alarm","record/config":"http://192.168.188.77/api/record/config","record/live":"http://192.168.188.77/api/record/live"}}
?

Hier wäre auch ein Link zu Github: https://github.com/lumapu/ahoy

oder wäre das hilfreich (XXX ersetzt persönliche Daten):

Code: Alles auswählen

{"wifi":{"ssid":"XXXXXXXXXX","pwd":"","dev":"AHOY-DTU","adm":"XXXXXX","prot_mask":61,"dark":false,"ip":"","mask":"","dns1":"","dns2":"","gtwy":""},"nrf":{"intvl":15,"maxRetry":5,"cs":15,"ce":2,"irq":0,"sclk":0,"mosi":0,"miso":0,"pwr":1},"ntp":{"addr":"pool.ntp.org","port":123},"sun":{"lat":51.XXXXXXXXX,"lon":6.3XXXXXXXX,"dis":true,"offs":0},"serial":{"intvl":5,"show":false,"debug":false},"mqtt":{"broker":"","port":1883,"user":"","pwd":"","topic":"inverter","intvl":0},"led":{"0":255,"1":255,"act_high":false},"plugin":{"disp":{"type":0,"pwrSafe":false,"pxShift":true,"rotation":0,"contrast":60,"data":255,"clock":255,"cs":255,"reset":255,"busy":255,"dc":255}},"inst":{"en":false,"rstMidNight":false,"rstNotAvail":false,"rstComStop":false,"iv":[{"en":true,"name":"Hoymiles","sn":18972783XXXX1,"yield":[0,0,0,0],"pwr":[365,365,0,0],"chName":["Ost","West","",""]}]}}
?

Einer der Endpoints im ersten JSON müsste die aktuellen Daten liefern. Das musst Du ausprobieren und wenn Du fündig geworden bist daskomplette JSON inkl. passendem Endpoiont posten.

Ich würde mal gerne das JSON aus dem Endpoint live sehen.

Bitte beim Ersetzen aufpassen, dass du keine Zahlenwerte mit X überschreibst sondern mit einer Zahl! Ich suche ungern nach Parsing Fehlern😉

Ich bitte Nachsicht, wenn mir nicht ganz klar ist, was mit "live sehen" gemeint ist. Ich habe von Programmierung leider keine Ahnung...

Hier Liste, wie sie aus "api/live" kommt:

Code: Alles auswählen

{"generic":{"wifi_rssi":-75,"ts_uptime":49,"menu_prot":true,"menu_mask":61,"menu_protEn":true,"esp_type":"ESP8266"},"refresh":15,"ch0_fld_units":["V","A","W","Hz","","°C","kWh","Wh","W","%","var"],"ch0_fld_names":["U_AC","I_AC","P_AC","F_AC","PF_AC","Temp","YieldTotal","YieldDay","P_DC","Efficiency","Q_AC"],"fld_units":["V","A","W","Wh","kWh","%"],"fld_names":["U_DC","I_DC","P_DC","YieldDay","YieldTotal","Irradiation"],"iv":[true,false,false,false,false,false,false,false,false,false]}
Vielleicht hilft auch ein Screenshot weiter:

Da snd ein paar Beschreibungen drin, aber keine aktuellen Messwerte. Geh wie geschrieben einfach alle Endpoints durch.

Ich glaube, ich habe es in der /api/record/live gefunden. Leider weiß ich nicht, wie man es formatiert (es ist alles untereinander geschrieben), aber vielleicht kannst du trotzdem etwas damit anfangen:

Code: Alles auswählen

{"inverter":[[{"fld":"U_DC","unit":"V","val":"34.30"},{"fld":"I_DC","unit":"A","val":"2.48"},{"fld":"P_DC","unit":"W","val":"84.70"},{"fld":"YieldDay","unit":"Wh","val":"686.00"},{"fld":"YieldTotal","unit":"kWh","val":"404.91"},{"fld":"Irradiation","unit":"%","val":"23.21"},{"fld":"U_DC","unit":"V","val":"34.40"},{"fld":"I_DC","unit":"A","val":"2.51"},{"fld":"P_DC","unit":"W","val":"86.20"},{"fld":"YieldDay","unit":"Wh","val":"403.00"},{"fld":"YieldTotal","unit":"kWh","val":"390.63"},{"fld":"Irradiation","unit":"%","val":"23.62"},{"fld":"U_AC","unit":"V","val":"229.80"},{"fld":"I_AC","unit":"A","val":"0.71"},{"fld":"P_AC","unit":"W","val":"163.20"},{"fld":"Q_AC","unit":"var","val":"0.10"},{"fld":"F_AC","unit":"Hz","val":"49.99"},{"fld":"PF_AC","unit":"","val":"1.00"},{"fld":"Temp","unit":"°C","val":"25.40"},{"fld":"ALARM_MES_ID","unit":"","val":"1.00"},{"fld":"YieldDay","unit":"Wh","val":"1089.00"},{"fld":"YieldTotal","unit":"kWh","val":"795.54"},{"fld":"P_DC","unit":"W","val":"170.90"},{"fld":"Efficiency","unit":"%","val":"95.49"}]]}
