Hallo
Also über Mqtt läuft die Truma an über befehle
Wie bekomme ich das in Node red rein ?
Also läuft soweit sogut bei mir , wie kriege ich das jetzt aufs Touch display ? Kann ich das irgendwie ändern ?

Hier ist der Flow für die Trumanita:

Damit wird die Truma CI Variable auf true gesetzt, damit die Truma in der App und auf dem Touchdisplay angezeigt wird. Dann greifen wir die Befehle, die wir eigentlich an das CI Script senden per MQTT ab und wandeln sie um für das Trumanita Script. Bitte beachtet dabei, dass nicht alle Daten zu 100% stimmen, aber grundsätzlich lässt sich die Truma damit steuern.
Die Dokumentation dazu findet ihr auf Github
Es ist nicht intensiv getestet worden, ob alle Befehle korrekt übersetzt werden und entsprechend ankommen
Das ist nur für die App und das Touchdisplay, aus dem Dashboard heraus werden die Befehle anders abgesetzt!

Das hätte ich mir vor 2 Wochen gewünscht, vermutlich wäre eine reine MQTT verbindung dann doch möglich gewesen.
Gruß Arno
Man muss dem Problem auch immer mal etwas Zeit geben sich von selbst zu lösen 
Aber ich bin gespannt auf deine Ergebnisse nächsten September!

Ahh werde es nach dem Wochenende testen, bei mir ging das Display nicht mehr wenn ich die portes anschalte im Pi menu
Hallo vincent , werde morgen den Teumanita flow testen , ich hatte aber immer , also davor schons als trumanita ging ohne display , das problem das das Display immer auf einen Art schleife gin , also Ladebildschirm und ich es nur durch neu formatieren wieder ging !
Irgendwie begann das problem Immer wieder wenn ich den port aktiviere wie in dee trumanita beschreibung
Ist das problem bekannt ?
Ich habe einen core Pcb
