@mousenray sagte in Node Red Victron mqqt schreiben:

ja das value müsste noch weg, eine zahl reicht. zum visualisieren!

Na dann musst an der payload ja gar nichts machen - und stellst das auf on release ein. Dann kommt nur der letzte Wert als Zahl raus.

@mickym

Brauche da noch mal Hilfe, ich möchte das sich der Status des Set Points mit ändert.
Also das mir Änderungen die ich zb an der Wallbox app mache, am Slider mit aktualisiert wird.

Danke

@mousenray Umdrehen,

Du willst am Eingang die payload auf payload.value setzen

Also umdrehen:

[Mousenray]

@mickym

Das habe ich versucht, geht nicht

[mickym]

@mousenray Dann poste was aus der mqtt rauskommt also debug 70

[Mousenray]

@mickym

"{"value": 10}"

[mickym]

@mousenray Ja dann geht das . was ich gepostet habe - poste das debug Fenster als Screenshot mit der debug 70 Node. ;)

Ansonsten geht das:

Ach so ich sehe Du hast was falsch in der mqtt-Node konfiguriert:

Warum auch immer. ;)

das sagt die node.

screen muss ich schauen wie das hier geht

[Mousenray]

@mickym

ja das war es, Danke!!!!

[mickym]

@mousenray Nochmal die mqtt Node muss das Objekt analysieren.

Im debug 70 steht das Objekt - im debug 69 nur noch der Wert.
