MQTT Bluepalm B2500

[Beta-User]

wäre es verständlicher/leichter auf Anhieb zu lesen/verstehen.

Der Schnippsel ist (als one-liner) eh' kaum lesbar .
Und die Aufgabenstellung war insgesamt auch eher von der Art, von der ich angenommen hatte, dass es besser ist, das als Code zu liefern wie als "lies das und das!"-Variante .

Aber es freut mich, dass anscheinend etwas breiteres Interesse an solchen Schnippselchen besteht .

Hallo Forum,
wie kann der MQTT Server, also fehm, den Payload schicken?
Danke

Wenn ich z.B. den Payload CD=01 an den Speciher schicke bekomme ich eine Antwort, die folgendermaßen außsieht und in ein reading geschrieben wird:

[TomLee]

Das ist in der Bedienungsanleitung (help MQTT2_SERVER) beschrieben.

[SaibotRetsevlis]

Danke hat funktioniert

Hallo druschba,
nachdem ich jetzt endlich "das Original" von Marstek habe, möchte ich den auch gerne in Hem einbinden.

Wie genau hast du den eingebunden nachdem du MQTT auf dem Gerät aktiviert hast?
Soweit ich das sehe, muß man den ja regelmäßig selber abfrage, d.h. man erstellt sich ein doif oder at welches einen Befehl per MQTT sendet und bekommt dann die Antwort. Würdest du dein MQTT Device und das Device für die Abfrage hier posten. Sonst muß ich und alle anderen nach mir das Rad neu erfinden wenn wir den Speicher einbinden wollen.

Alter Thread ich weis,
aber hat jemand inzwischen Bluepalm / Marstek / Saturn / Tronic - b2500(-d) Speicher per MQTT am laufen?

Ich habe gerade das Projekt ESPHome B2500 ( https://tomquist.github.io/esphome-b2500/ )
für meine zwei Marstek B2500-D aufgesetzt, damit bekommt man MQTT Daten ohne die
Marstek App zum FHEM geschickt, aber ich habe definitiv Probleme mit der Auswertung!

Wäre wirklich cool wenn da schon jemand was gebastelt hätte....

[DeeSPe]

Damit MQTT aktivieren und damit vernünftige Readings erzeugen lassen.
Das läuft bei mir seit paar Monaten sehr gut.

Ich habe den ESPHome B2500 laufen. Ich will die Marstek App gerne weiter nutzen, weil die Nulleinspeisung (Automodus) mit dem EcoTracker recht gut funktioniert.
Das geht mit der von @DeeSPe beschriebenen Lösung nicht - die sollte man nehmen, wenn man "cloudfrei" arbeiten will.
So sehen meine Readings etc. aus:

Die App funktioniert (über Bluetooth) genau so weiter wie vorher.
Ich habe auch einen EcoTracker und die Batterien benutzen diesen auch wunderbar.
Deshalb reicht mir meine Lösung auch, weil ich nur die Readings auswerten möchte und keine Steuerung über FHEM benötige.
