Integration SMA Energymeter v1 mit multicast

Hallo,
Ich versuche, die Daten von meinem SMA energymeter mit multicast einzulesen. Die vorhandene SMA Integration funktioniert nur für neue Wechselrichter mit Webserver. Gibt es jemand im Forum, der mir dabei helfen kann? Danke!
 
Hi,
ich sammle die Daten via Node-Red ein und pushe sie dann über MQTT an HA. Wenn interesse besteht kann ich den Flow gerne mal teilen ;)
 
Et voilá ;)

Du musst natürlich die Angaben zu deinem MQTT Broker anpassen. Ich habe das selbst vor einiger Zeit im Internet gefunden und übernommen, daher kann ich keinen großartigen Support leisten, sollte es nicht funktioniern :oops:
