@mickym said in Bei Wertüberschreitung soll EMail gesendet werden:

Nimm einfach eine trigger Node. Wenn die dann nicht mehr triggern soll, dann schickst Du ein msg.reset

Das war ja einfach. Danke!

Vielen Dank für deine Hilfe. So wie es aussieht komme ich unter HA unter Helfer weiter...
Bleibt noch die Frage, wie ich bei dauerhaftem überschreiten der Differenzspannung alle X Stunden eine EMail erhalte.

VG und Danke

So, hab die Differenz in HA hinbekommen. Ist ein Mix aus deinem Tipp mit der Node und Entität erstelllen und einen Helfer in HA erstellen -> link text

Hallo,
ich möchte zwei Batteriespannungen überwachen. Wenn sich dort eine Differenz von 0,2V abbildet, soll einmal am Tag, alternativ alle x Stunden eine EMail an mich rausgehen. Die Schaltung funktioniert. Ich trigger die Batteriespannungen alle 20s an. Hab es soweit, dass bei Überschreitung der 0,2V die EMail (dann) alle 20s rausgeht. Der 20s Trigger ist gesetzt und soll nicht verändert werden.
Die Email Node ist hier nicht angehängt.

Dann würde ich gerne den positiven Wert der Function Node "Positiver Wert" im Dashboard von HA zur Verfügung haben. Im Bild habe ich ja bereits die beiden Batteriespannungen gesetzt, wie ich den Wert dort verfügbar mache weiß ich überhaupt nicht.

Danke euch im voraus

@mickym Danke... heute krieg ich das nicht mehr auf die Kette. Die letzten beiden Sätze muss ich mir morgen nochmal genauer ansehen.

Lasse die Funktion jetzt so wie sie ist.

Was mir immer noch fehlt ist, dass link nodes beim Start des ESP beglockt werden sollen.

@mickym Ich halte auch nicht so viel von den festen Zeitabständen. Ich hatte ja geschrieben, dass ich manchmal den Standort des Gerätes ändern möchte. Dann ist der ESP32 spannungslos. Beim Neustart muss der Zustand der Anlage ("WR" im Bild) ja abgefragt werden, um die Funktion der "Handstart LED ok" zu gewährleisten. Der Zustand kommt aus meinem Pi, der 24/7 läuft. Hier ändert sich der Zustand der Anlage meistens nur 1 bis 2x am Tag. Somit funktioniert die Handstart LED nur, wenn die Anlage ihren Zustand irgendwann geändert hat und nicht "sofort".

Hier ein Screenshot kurz nach Neustart ESP. Einmal "current state" und einmal "events state"

Zum Abschluß noch wo die link nodes beim ESP Start geblockt werden sollen

@mickym Wow, wieder mein Retter. Das hätte ich so nicht geschafft. Die Abfrage der Spannung und des Anlagenstatus habe ich über eine "current state" node alle 20s parallel abgefragt. Hier hat es bei Anlage Start und Spannung zu gering komischerweise manchmal zum hin und herschalten der LED geführt. Nachdem ich eine Verzögerung von 100ms für die Spannung eingebaut habe ist Ruhe. Mit Inject nodes hat es von vorherein geklappt.

Eine Zusatzfrage... mein Programm läuft auf einem ESP32. Diesen möchte ich mobil im Haus nutzen. Heißt mal hier anstecken und mal da. Wenn der ESP hochfährt, dann werden zwei "link in/out" nodes aktiviert. Das verhagelt mir Funktionen, die auf meinem Raspi laufen, der 24/7 an ist. Gibt es die Möglichkeit beim Start die nodes nicht abzufragen?

Ganz dickes Danke

Hallo,
ich kriege die einfache Funktion nicht sauber hin. Oberhalb einer Spannung X soll eine LED signalisieren, dass die Anlage per Hand gestartet werden kann. Unterhalb Spannung X soll die LED aus sein. Als Erweiterung soll die LED auch oberhalb Spannung X ausgehen, wenn die Anlage gestartet wurde. Wird die Anlage oberhalb der Spannung X ausgeschaltet, soll die LED wieder an gehen.

Danke und Gruß

@mickym Danke für die Erklärung

@mickym Nur interessehalber... was habe ich denn im Ausgangspost falsche gemacht, wenn ich den Zustand in mehreren Flows nutzen wollen würde?
