      @glitzi sagte: Gerade der Teil wo ich die unterschiedlichen Zeit Stempel zerlegen muss, diese können täglich variieren.

      Von Datenbanken habe ich keine Ahnung, weshalb ich das Schreiben in die DB nur als Kommentar angegeben habe. Wie muss der Zeitstempel in der InfluxDB vorliegen? In meinem Vorschlag - der direkt nach

            let res = JSON.parse(body).result.watts;  // res ist ein Objekt
      

      ausgeführt werden muss - werden die Zeiten im Objekt res in ms umgerechnet und stehen in der Variablen ts zur Verfügung.

        So hier mein versuch, leider ist noch ein Fehler im Skript vermutlich unten bei den Klammern...

        Nochmal ergänzend, ich möchte jetzt dann folgendes tun...

        Die Zeit und den zugehörigen Wert aus dem Result '2021-05-27 12:00:00' :1234, für alle Werte aus dem Result in die InfluxDB schreiben.
        Geliefert werden immer zwei Tage, hiervon möchte ich jedoch immer nur den aktuellen Tag.

        {'watts':{'2020-12-15 07:49:00':0,'2020-12-15 08:25:00':80,'2020-12-15 09:00:00':590,'2020-12-15 10:00:00':1230,'2020-12-15 11:00:00':1810,'2020-12-15 12:00:00':2040,'2020-12-15 13:00:00':1560,'2020-12-15 14:00:00':1120,'2020-12-15 15:00:00':570,'2020-12-15 15:41:00':80,'2020-12-15 16:22:00':0,'2020-12-16 07:50:00':0,'2020-12-16 08:25:00':60,'2020-12-16 09:00:00':380,'2020-12-16 10:00:00':770,'2020-12-16 11:00:00':1140,'2020-12-16 12:00:00':1400,'2020-12-16 13:00:00':1360,'2020-12-16 14:00:00':1080,'2020-12-16 15:00:00':560,'2020-12-16 15:41:00':80,'2020-12-16 16:22:00':0},'watt_hours':{'2020-12-15 07:49:00':0,'2020-12-15 08:25:00':50,'2020-12-15 09:00:00':390,'2020-12-15 10:00:00':1620,'2020-12-15 11:00:00':3430,'2020-12-15 12:00:00':5470,'2020-12-15 13:00:00':7030,'2020-12-15 14:00:00':8150,'2020-12-15 15:00:00':8720,'2020-12-15 15:41:00':8780,'2020-12-15 16:22:00':8780,'2020-12-16 07:50:00':0,'2020-12-16 08:25:00':40,'2020-12-16 09:00:00':260,'2020-12-16 10:00:00':1030,'2020-12-16 11:00:00':2170,'2020-12-16 12:00:00':3570,'2020-12-16 13:00:00':4930,'2020-12-16 14:00:00':6010,'2020-12-16 15:00:00':6570,'2020-12-16 15:41:00':6620,'2020-12-16 16:22:00':6620},'watt_hours_day':{'2020-12-15':8780,'2020-12-16':6620}}

        schedule({hour: 00, minute: 30}, GetSolar );
         
        function GetSolar() {
            request(options, function(error, response, body) {
            if (!error && response.statusCode == 200) {
                let res = JSON.parse(body).result.watts;  // info ist ein Objekt
                log(res);
                for(let key in res) {

                    let watt = res[key];
                    log(ts);
                    log(watt);
                // in DB schreiben
                }
        }
            }
        
        

        Bezüglich der Zeit, der Ursprungscode zum schreiben in die DB war folgender

        sendTo('influxdb.0', 'storeState', {id: 'Temperaturen.Außen.Tagesdurchschnitt2', state: {ts: (new Date().getTime()) - 86400000, val: getState("javascript.0.Aussentemperaturen.Tagesdurchschnitt.Durchschnitt").val, ack: true, from: "javascript.0", q: 0}});

          Ja, verwende Einrückungen konsequent, um solche Fehler zu erkennen.

          var options = {url: 'https://api.forecast.solar/estimate/*STANDORT*/-2/12.73', method: 'GET', headers: { 'User-Agent': 'request' }};
           
          function GetSolar() {
              request(options, function(error, response, body) {
                  if (!error && response.statusCode == 200) {
                      let res = JSON.parse(body).result.watts;  // res ist ein Objekt
                      log(res);
                      for(let key in res) {
                          let ts = new Date(key).getTime() - 172800000; // 2 Tage zurück in ms
                          let watt = res[key];
                          log(ts + ': ' + watt);
                          sendTo('influxdb.0', 'storeState', {id: 'PV_Forecast', state: {ts: ts, val: watt, ack: true, from: "javascript.0", q: 0}});
                      }
                  }
              });
          }
          
          schedule('30 0 * * *', GetSolar);

            Super, das sieht erstmal sehr gut aus. DANKE!

            ich glaube bei dem Abschnitt haben wir uns falsch verstanden 🙂

            let ts = new Date(key).getTime() - 172800000; // 2 Tage zurück in ms
            

            Folgende Daten Kommen aus der abfragte, davon möchte ich immer nur den aktuellen Tag in die Datenbank schreiben.
            Es könnte sein das auch je Tag mehr oder weniger Einträge übermittelt werden.

              Dann muss das Datum geprüft werden:

              var options = {url: 'https://api.forecast.solar/estimate/*STANDORT*/-2/12.73', method: 'GET', headers: { 'User-Agent': 'request' }};

                  request(options, function(error, response, body) {
                      if (!error && response.statusCode == 200) {
                          let res = JSON.parse(body).result.watts;  // res ist ein Objekt
                          for(let key in res) {
                              if(key.substr(0, 10) == formatDate(new Date(), 'YYYY-MM-DD')) {
                                  let ts = new Date(key).getTime() - 86400000; //  1 Tag zurück in ms
                                  let watt = res[key];
                                  log(ts + ': ' + watt);
                                  sendTo('influxdb.0', 'storeState', {id: 'PV_Forecast', state: {ts: ts, val: watt, ack: true, from: "javascript.0", q: 0}});
                              }
                          }
                      }
                  });
              }

                DANKE!

                Ohne das - 86400000 ist es das was ich brauche.

                Somit das Fertige Script für den PV Forcast über die Webseite Forecast.Solar und die Speicherung in der InfluxDB.

                var options = {url: 'https://api.forecast.solar/estimate/MEINE Koordinaten/Meine Koordinaten/35/-2/12.73', method: 'GET', headers: { 'User-Agent': 'request' }};
                 
                function GetSolar() {
                    request(options, function(error, response, body) {
                        if (!error && response.statusCode == 200) {
                            let res = JSON.parse(body).result.watts;  // res ist ein Objekt
                            for(let key in res) {
                                if(key.substr(0, 10) == formatDate(new Date(), 'YYYY-MM-DD')) {
                                    let ts = new Date(key).getTime(); //  1 Tag zurück in ms
                                    let watt = res[key];
                                    log(ts + ': ' + watt);
                                    sendTo('influxdb.0', 'storeState', {id: 'PV_Forecast', state: {ts: ts, val: watt, ack: true, from: "javascript.0", q: 0}});
                                }
                            }
                        }
                    });
                }
                 
                schedule('30 0 * * *', GetSolar);

                  Die Grafiken sehen alle aus wie Glockenkurven, die aus dem Wechselrichter sind aber extrem gezackt (ist ja auch klar wegen der Bewölkung).
                  Kann man denn die Prognose für das Schalten von Verbrauchen überhaupt gebrauchen? Es gibt auch Seiten die den Bewölkungsgrad des Himmes im Stundenryhtmus angeben: brightsky.dev auch kostenlos. Fährt man da nicht besser mit? oder evt sogar beide Daten miteinander verknüpfen?
                  Ich glaube zumindest nicht das Mittags immer die Wattzahl am größten ist.

                    Ja das Stimmt, ist ja wie beim Wetterbericht 😉
                    Ich vermute die nutzen für die Prognose auch die Bewölkung und ein paar andere Werte als Grundlage.

                    Anbei mal ein Bild von heute aus der Nähe von Kassel
                    grün= hochgerechnet aus einem Messwert der Globalstrahlung
                    gelb= Prognosewerte
                    in 3 Wochen bekomme ich meine PV, dann sehe ich was wirklich passiert

                    02f7937d-68c7-4d13-827d-92106f71f2df-image.png

                    wenn man es ordentlich glättet, kommt es etwas besser hin, aber 2-3 km weiter kann es schon ganz anders aussehen.

                      Wenn ich mal ganz doof fragen darf - was bringt es dir die Prognose Daten in eine Datenbank zu schreiben? Historisch betrachtet ist es doch sowas von egal, wie z.B. am 20. Februar die Prognose für den 21. Februar war.

                      OK, du kann es so in Grafana als Trend darstellen. Dabei produzierst du dir aber jede Menge "Datenmüll", welchen du dir wahrscheinlich nie wieder ansehen wirst. (bestenfalls im 1 Jahr wenn noch alles neu ist und du deine "Lernkurve" zum Thema PV hast)

                      Ich bin auch ein großer Freund von Grafana, aber das PV Prognose Skript auf Basis des Materialdesign Adapters, reicht mir persönlich völlig.

                      Ich will damit auch nichts steuern, sondern einfach nur eine ungefähre Tendenz haben, ob es ggf. heute besser ist die Waschmaschine zu starten, als morgen. Alles andere läuft eh über PV Überschuss freigaben und die entsprechenden Skripte.

                        Da stimme ich Dir zu, ich nutze halt gerne Grafana und kann so schön die Prognose mit den realen Werten übereinanderlegen.
                        Und im Vergleich sind die 20 Werte/Tag ggü. 30 Sek. Messwerten Peanuts 😉

                              Hochrechnen ist übertrieben, ich habe einfach die Globalstrahlung einer Messstelle im Umkreis mit meiner Anlagenleistung multipliziert. Generell sollte es grob stimmen, hier in der Region haben wir laut Statistik ca. 1000W/m² im Sommer. (Bei dem Wert wird ja auch die Modulleistung angegeben)

                              Mitte Juni kommt Die PV aufs Dach, dann kann ich sehen ob es annähernd stimmt. Aber alleine die 10km Entfernung zur Messtelle haben schon einen ordentlichen Versatz wenn ein Wolkenfeld durchzieht.

                                  @martybr Wozu? Installiere einfach mehrere Instanzen...

                                    Das kann man auch machen. Aber dann fehlen die summierten Werte.
                                    Vielleicht kann hier auch jemand den Fehler finden. Ich teste ja das Script und benutze hier den Public-Zugang, daher auch keine API. Das ist so im Script beschrieben, dass bei einem solchen Zugang const api auskommentiert werden soll.
                                    Die anderen Fehlermeldungen kann ich nicht interpretieren.

                                      @martybr sagte: bei einem solchen Zugang const api auskommentiert werden soll.

                                      Nicht auskommentieren, sondern einen Leerstring zuweisen. Zeile 93:

                                      const api = '';

                                          Die Daten des dritten Strings fehlen in dem DP SolarJSINGraph. Ich warte mal bis morgen ab, ob das Script die Daten noch integriert.
