mein Start bei der Solaranlage war ein System, das ich als Paket installiert bekommen habe:
Victron Cerbo GX mit Multiplus und ET340 als Zähler für den Cerbo, dazu ein chinesischer Wechselrichter.
Der Wechselrichter war nicht im Victron Sytem eingebunden und im VRM (Victron) Portal stimmte nicht einmal mein Verbrauch.
Inzwischen bietet Victron sogar ein ESS System mit PV Vorhersage an, das konnte mein System aber nicht nutzen. Ich weiss nicht, wie das ESS System funktioniert, aber Venus OS hat jetzt Node Red als Erweiterung installiert, so dass man selber ohne grosse Programmierkenntnisse (wie ich) kleine Abhängigkeiten programmieren kann. Mein Anlage speist bis 9:30 Uhr ein, wenn die Vorhersage über 25 kWh und die Batterie über 25%SOC hat. Dann startet erst die Ladung der Batterie.
Für solche Systeme habe ich jetzt eine Lösung gefunden. über MQTT kann man jeden Wechselrichter, der in der Solaranzeige läuft jetzt in das Venus OS System des Cerbo GX einbinden.
In dem verlinkten Youtube Video wird das erklärt, vielen Dank dafür, falls du mal vorbeikommst. Leider hat Matthias sein Node System nicht geteilt. Ich habe das jetzt nachgebastelt, wobei ich einige Sachen anders ans laufen gebracht habe, z.B. weil Inzwischen Venus OS den MQTTBroker auf flash MQ umgestellt hat. Einen Zähler einzubinden habe ich nicht probiert.

Das muss man erst erledigen und das dauert auch ein bisschen.
Im Gegensatz zu dem Video und zur Anleitung download/MQTT%20Informationen%20zur%20Solaranzeige.pdf) muss man in der Solaranzeige in der user config einen $MQTTBenutzer eingeben. wer es sich einfach macht gibt "solaraz" ein, das steht schon in meinen Nodes (unter Sicherheit)
Sonst muss der user in den MQTT nodes dem in der Solaranzeige entsprechen.
Was nicht funktioneirt hat, war die Portal ID und die client ID aus der MQTT Antwort von Venus OS herauszulesen. Ich bin kein Fachmann, die Node ist deaktiviert mit angehängt, vielleicht findet sich jemand, der den Fehler findet. Der Vorteil wäre, dass die Node dann direkt bei jedem funktionieren würde.
Zu Fuss muss man die Anmeldung einmal auslösen und den deploy tab öffnen, dann erhält man so eine Antwort

W: "W/102Portid932/pvinverter/1"Ihr benötigt die "portalId" hier "102portid932" die muss in die MQTT Node Package an Konsole Handeintrag eingetragen werden.
- Eintrag Portal ID
Das VRM Portal benötigt:
AC Leistung gesammt (W)
AC Leistung pro Phase (W)
Tagesleistung (kWh)
Angezeigt werden noch AC Strom und AC Spannung pro Phase, ich glaube damit rechnet aber Venus OS nicht.
Tagesleistung pro phase würde angezeigt, die habe ich mir gespart zu berechnen.
Es ist sicher sinnvoll die MQTT Ausgabe der Solaranzeige gemäss Anleitung anzuzeigen und zu schauen, ob die Werte unter dem richtigen Namen ausgegeben werden.
