Hi,
vielen Dank für die schnell Antwort.
Ich kann frei wählen, wie oft per mqtt der Zählerstand gemeldet wird.
Dein Screenshot sieht klasse aus - was hast du denn da dahinter stehen (welches virtuelle Device, etc)
?
Das muss ich schauen, ist schon sehr lange her als ich das angelegt habe.
Das wäre klasse, wenn Du da heute Abend mal schauen könntest.

Ist der komplette Flow für das Gerät, schau ob es dir hilft.
Wenn du noch Fragen hast dann nur zu.
1 „Gefällt mir“
Hallo @Domino1707,
je nach dem, wie genau (mit wievielen Nachkommastellen) dein Zählerstand übermittelt wird, kannst Du z. Bsp. auch einen „aktuellen Verbrauch“, also den Schnitt über die Zeit zwischen 2 Auslesungen ermitteln.
@Micha woher nimmst Du den „aktuellen Verbrauch“, übermittelt dein Zähler den Wert im Moment des Auslesens?
@Micha
Danke- das probiere ich heute abend mal aus!!!
@anon39850074
Wo kann ich denn den Schnitt bzw. die Berechnung dazu durchführen?
Das kannst du alles in Node Red machen.
Das errechnen der Tages ,Wochen und Monats Verbrauch wird auch dort gemacht.
@anon39850074 das ist ein Energiemanager von dem ich die Daten bekomme.
Vielen Dank!
Eine Frage habe ich tatsächlich:
Was steckt denn hinter den „ioBroker in“ Nodes - was genau wird da geliefert?
Der Zählerstand
Hi,
ich habe versucht, den Flow mit einem Test-JSON anzupassen.
Funktioniert aber leider nicht ;-(
Kannst Du Dir das mal anschauen?

Mach ich gerne aber erst morgen 
Das ist nett von Dir, danke! Die beiden DEBUG-Nodes sind noch deaktiviert - habe ich gerade gesehen.
Was mir noch nicht ganz klar ist, ist einerseits wie du die Berechnungen für Tag, Woche Monat durchführst - ich habe zwar die jeweilige Funktion gesehen, aber irgendwo müssen doch auch Vergleichswerte gespeichert werden, oder?
Und andererseits die Berechnungen an sich, hier dividierst und subtrahierst Du ja fleißig - mir ist aber noch nicht ganz klar, was da dahinter steckt.
Beispiel: Der Node der den Gesamtverbrauch des Tages berechnet:
return {payload: ((parseFloat(msg.payload)-11815340.7)/1000)+71337.81}
Was steckt denn hinter den Zahlen?
Habe es dir nochmal zusammengestellt so wie du es brauchst.

Die Berechnungen liegen an meinen Zähler und meinen separaten Energymeter . Damit der Zählerstand stimmt musste ich beim Einbau den alten Zählerstand abziehen etc.
Wenn du die Funktion benutzt musst du die automatischen inject einmal auslösen, damit auch der Verbrauch sich ändert ansonsten musst du entsprechend warten bis diese automatisch auslösen.
Tag löst nachts um 0:01Uhr , Woche Montag um 0:02Uhr und Monat immer am 1. um 0:02 Uhr.
Ich speichere immer den Gesamtverbrauch und zu den entsprechenden Zeiten wird der Gesamtverbrauch dann auf den Tag , Woche oder Monat gespeichert.
Daher kann es sein das erst am zweiten Tag der Tagesverbrauch angezeigt wird wenn du nicht manuell triggerst.

Aha, ich lese meinen Stromzähler an der iR-Schnittstelle aus, das dauert recht lange, weil zum einen die Datenübertragung recht langsam ist zum anderen werden aber auch viele Daten übertragen. So werden neben dem Zählerstand z.Bsp. Verbrauch vom aktuellen Monat, Vormonat, -jahr und und und direkt übermittelt. Der Momentanverbrauch aber nicht.
Diese Schnittstelle ist ja nicht für Automationen, sondern für den Ablesedienst gedacht, daher ist das verständlich. Da der Zählerstand aber auf 3 Nachkommastellen, also auf’s Watt genau übertragen wird, bilde ich den Schnitt über die Zeit zw. zwei Auslesungen.
@Domino1707 ich speicher den vorherigen Zählerstand in einer globalen Variable, um den Durchschnittsverbrauch über 5 min. zu ermitteln.
Ich stelle meinen Flow hier auch mal ein, vielleicht nützt dir’s ja…

Das ist halt bei einer IR Schnittstelle klar das hier die Daten etwas länger brauchen, gerade wenn du so viele übermittelt bekommst.
Hallo Ihr zwei,
vielen Dank Euch - ich werde beide Ansätze mal probieren und mal schauen, was für meine Umgebung am besten funktioniert 
Ich bekomme meine Daten auch „nur“ über die IR-Schnittstelle - und leider auch nur relativ ungenau (100W Schritte).
… so, habe fleißig probiert. Ich denke, ich werde bei Michas Ansatz bleiben (müssen). Mein Zähler gibt über die IR Schnittstelle tatsächlich nur den Gesamtzählerstand aus.
@anon39850074 : Ich bin etwas neidisch auf Deinen Zähler - das gibt deutlich einfachere Möglichkeiten
Ich probiere das jetzt mal ein paar Tage und dann melde ich mich bestimmt nochmal
1 „Gefällt mir“
Das musst Du nicht, den bringt der Netzbetreiber mit, auf das verbaute Gerät haben wir alle keinen Einfluß.
Ich weiß ja nicht, was genau Du vor hast, es gibt ja jede Menge anderer Smartmeter.
Da Du ja NodeRed evtl. auch ioBroker am Laufen hast, ist da echt viel möglich, klar die müssen eingebaut werden und das sollte von Fachpersonal*innen erfolgen, aber es gibt da schon Alternativen. Auch z.Bsp. Shelly hat da was im Portfolio, was dann direkt komptibel zu homee wäre.
Der Stromzähler selber hat für mich nur informativen Charakter, ich habe auch noch ein Smartmeter (EM24 Ethernet), das per ModbusTCP jede Menge Verbrauchsdaten liefert.
Das Smartmeter wiederum ist bei mir aber in erster Linie für den ESS Betrieb der Solaranlage zuständig/notwendig.
Grüße Heko…
