Zwei Strings zusammenführen
-
@peterfido vielen Dank, probiere es sofort am Freitag.
-
Die Funktion "msg.payload = flow.get("GelbDatum") + " (" + flow.get("GelbTage")+")";" funktioniert super (siehe Payload auf dem Bild). Nur leider erkennt die KNX Node den Payload nur zur hälfte (siehe Wert unter der Node). Hast du eine Ahnung wie es dazu kommt? Zu lang ist die Nachricht nicht. Sie ist genau 14 Werte Lang - so wie als maximum erlaubt.
-
@ju_
mangels KNX kann ich da nur spekulieren. Evtl. mag es die Leerzeichen nicht, die Klammer, oder irgendwas anderes. Da stehen nichtdruckbare Zeichen im Node. Wo kommen die her? Evtl. mal dessen Werte posten. -
@peterfido habe es bereits ohne Klammern und leerzeichen probiert. Bringt alles nichts. Aber die Debug Node zeigt immer das korrekte an. Ich weis nicht wieso die KNX Node die eigentlich druckbaren zeichen als nicht druckbare wertet.
-
@ju_ Ich habe eben mal geschaut. Du kannst wohl wählen, welches Datenformat Du willst. ASCII Zeichen, UTF8 Zeichen, etc.
Bei mir zeigt er aber keine Vorschau am Node selbst an. Habe ja auch keinen KNX-Bus, wohin das gesendet werden kann. Du kannst Dein Node-Diagramm ja mal exportieren und hier posten.
Bei mir sieht es so aus:
-
@peterfido kannst du mir erklären, wie ich ein "Node-Diagramm" exportiere? Dachte es geht nur über Bilder. Übrigend wenn ich über eine Inject Node direkt "27.01.25 (10d)" als "msg.payload" auf die KNX Node schicke funktioniert es. Also scheint sie irgendwas gegen den Output der Funktion zu haben.
-
@ju_ ja, bei mir geht es auch. Ich frage mich, mit welchem KNX sich die Node standardmäßig verbindet.
Exportieren geht über das Menü oben rechts in Node-Red.
-
@peterfido und dann als JSON?
-
@ju_ ja. Per JSON in die Zwischenablage und dann hier in Code-Tags posten.
-
@peterfido ist drin, musste ihn nochmal fix bearbeiten.
-
@ju_ probiere es mal als Code. So lässt es sich nicht importieren. Code-Symbol ist </>

@ju_ Das Symbol anklicken und dann zwischen den '' einfügen.

@peterfido habe ich verstanden, ist oben geändert. Sorry

Im Prinzip nur die Function Node:
if(msg.topic=="Datum"){ flow.set("GelbDatum", msg.payload.slice(0,8)); } if(msg.topic=="Tage"){ var s = msg.payload; for(var i=1;i<s.length;i++){ var x = s.slice(i,i+1); if(isNaN(x)){ flow.set("GelbTage", s.slice(0,i-1)); break; } } } node.status({ text: flow.get("GelbDatum") + flow.get("GelbTage") + " " + x }); if(flow.get("GelbDatum").length > 0 && flow.get("GelbTage").length > 0) { msg.payload = flow.get("GelbDatum").slice(0,8) + " (" + flow.get("GelbTage") + "d)"; node.status({text: msg.payload}); return msg; }Ich habe es nochmal editiert.
Im Start-Bereich der Function die Variablen zurücksetzen. Sonst bleiben die alten Werte.
flow.set("GelbDatum",""); flow.set("GelbTage", ""); -
@peterfido vielen Dank, probiere es gleich morgen früh aus! Melde mich.
-
@peterfido Es funktioniert! Vielen lieben Dank für deine Hilfe und deine Gedult!!
-
@ju_ Prima. Danke für die Rückmeldung.
Edit: In den beiden Change-Nodes kann die Regel, wo die Werte nach flow.Datum und flow.Tage geschrieben werden, raus. Da brauchts nur das Topic. Den Rest macht die Function.
Die nimmt vom Datum die ersten 8 Stellen und vom Tage sucht die sich nur die Ziffern am Anfang raus. Wenn beides gefunden wurde, wird es weitergeleitet.
