Hilfe bei NodeRed wegen Status Fenster/Türen
-
Hallo zusammen,
ich benötige bitte mal einen Gedankenanstoss bei folgendem Vorhaben.
Wenn ich das Haus verlasse bzw. abends wenn ich schlafen gehe, möchte ich eine Benachrichtigung mit dem Status der Fenster und Türen bekommen.
Also Türen geschlossen, Fenster Bad auf etc..Meine Tür- und Fensterkontakte sind über zigbee2mqtt node eingebunden - hier gibt es eine Gruppe Fenster und eine Gruppe Türen die ich in der node definiert habe.
Ich kann den Status der jeweiligen Gruppen über die get zigbee2mqtt node abfragen und erhalte eine payload mit den einzelnen Kontaktsensoren und den jeweiligen Stati.
Wie kann ich jetzt eine Kontrolle der jeweiligen Sensoren auf den Status von msg.payload.*.payload.contact === false prüfen - also das ich nicht für jeden Sensor eine separate Überprüfung machen muss?
Den Platzhalter bzw. * funktioniert in der function node ja nicht - muss ich das über eine loop Funktion in der function Node abwickeln, oder wie komme ich meinem Ziel näher? Ich würde es auch Platzgründen gerne über eine function Node abwickeln.
In Blockly hatte ich das damals so geregelt
Hab gegoogelt und ein paar Beispiele probiert die aber nicht zum Ziel führen mangels korrekter Herangehensweise oder syntax - bin was javascript angeht nicht der Experte, kleinere Grundlagen bekomme ich hin bzw. hab ich mir in Eigenregie selbst beigebracht.
Danke für Tipps.

@mac89muc Am Besten hörst Du auf immer mit Javascript zu programmieren und nutzt JSONATA und filterst einfach nach Objekten, wo der Kontakt false ist.
Am Besten ist wenn Du Dein payload Objekt über die Schaltfläche Wert kopieren, hier in CodeTags reinstellst, dann kann ich Dir einen Vorschlag machen.
Also mit der Maus direkt wo markiert auf die Schaltfläche Wert kopieren und dann
hier in CodeTags einstellen - dann kann ich das in eine Inject Node packen und simulieren:

Im Prinzip habe ich halt keine Lust - immer alles aus den Screenshots abzuschreiben.

@mickym Kein Thema - vielen lieben Dank für die superschnelle Hilfestellung

So ich habe Dir mit Deinen Daten folgendes gebastelt:
Du siehst in der 1. Node werden alle geschlossenen Fenster selektiert. In der 2. Node alle offenen Fenster.
Hier der Flow zum Import:
Ich habe mal ein Dachboden-Fenster virtuell geöffnet, damit ein Ergebnis rauskommt.
Mit
payload.*[payload.contact=false]kannst Du also die Objekte leicht selektieren und somit auch gleich das topic ausgeben lassen.
payload.*[payload.contact=false].topicUm das für Dich selbst auszuprobieren und die verschiedenen Contact Sensoren auf true zu stellen, nutz am Besten auch einfach den JSONATA Exerciser:
https://try.jsonata.org/uEEVBxn2i
Links siehst Du Deine Quelldaten:
rechts oben den Code - der gleich das Ergebnis im unteren Fenster rechts anzeigt.Ach so und wenn Du Dir statt des topics gleich die friendly_names in Deinem Array ausgeben lassen willst, dann brauchst Du es in dem Objekt nur selektieren.
Also dann einfach:
payload.*[payload.contact=false].item.friendly_nameUnd wenn Du auch bei einem Ergebnis ein Array und keinen skalaren Text haben willst, dann halt das ganze in eckige Klammer setzen. Diese einfach Anhängen funktioniert nicht.
So erhälst Du also immer ein Array - auch mit nur EINEM Element.
[payload.*[payload.contact=false].item.friendly_name] -
@mac89muc sagte in Hilfe bei NodeRed wegen Status Fenster/Türen:
Ich würde es auch Platzgründen gerne über eine function Node abwickeln.
Verstehe ich zwar nicht - ein function Node - ist meines Erachtens viel umständlicher und braucht auch nicht mehr oder weniger Platz als eine Change Node???
Und ehrlich gesagt, habe ich wenig Lust wieder x-Zeilen Code zu schreiben, weil in dem Fall das Javascript einfach viel umständlicher ist und JSONATA einfach für diese Art abfragen gemacht wurde und JSONATA in NodeRed sehr gut unterstützt ist.
Wird auch in Blockly viel zuwenig genutzt.
-
Hier die relevanten Nodes nochmal zum Import (letzter Stand mit immer Array):
-
@mickym Wow - vielen Dank. Probiere ich die nächsten Tage aus und melde mich wieder. So, oder so schon mal vielen Dank
-
Falls Du doch lieber mit Javascript programmieren willst, habe ich Dir noch eine function Node gebastelt mit 2 Ausgängen, für Fenster offen und geschlossen.
Hier zum Import:
Der Code mit Javascript ist natürlich länger:
var arrOpened=[]; var arrClosed=[]; for (var key in msg.payload){ var obj; obj = msg.payload[key]; obj.payload.contact ? arrClosed.push(obj.item.friendly_name) : arrOpened.push(obj.item.friendly_name) } return [{ topic: "Fenster geschlossen", payload: arrClosed.length > 0 ? arrClosed : "Alle Fenster geöffnet" }, {topic: "Fenster geöffnet", payload: arrOpened.length > 0 ? arrOpened : "Alle Fenster geschlossen !" }];Aber ich habe die function Node gleich mit 2 Ausgängen gebastelt, so dass oben die geschlossenen Fenster und unten die offenen Fenster ausgegeben werden.
Ich würde Dir aber trotzdem raten auf function Nodes so lange wie möglich zu verzichten - da Du sonst leicht wieder in Versuchung kommst, herkömmlichen Code zu schreiben - mit Schleifen etc.
-
@mickym vielen lieben Dank für Deine Mühe!!! - hab ich importiert und funktioniert wie gewünscht.
In dem Fall bin ich komplett deiner Meinung mit dem Verzicht auf die Function node, ich dachte das wird etwas umfangreicher was die Anzahl der nodes angeht und da ist mir dann normalerweise eine Function node immer lieber. Aber in dem Beispiel sehe ich das genauso wie Du.
Beim Thema JSONATA muss ich mich mal einarbeiten, ich glaube das ist genau das was ich für ein paar Themen brauchen kann als Ansatz - Danke dafür.Hast Du ggf. noch einen kurzen Tipp für mich, wenn ich die geöffneten Fenster nicht in einem Array ausgegeben haben möchte, sondern in einem einzigen getrennt durch Kommas? Muss ich das Array danach nochmal anfassen und zusammenfassen? Das müsste dann doch bestimmt mit JSONATA auch schon in einem Aufwasch direkt funktionieren, oder??
Viele Grüße

Einfach das Array in eine Join Funktion geben.
https://docs.jsonata.org/string-functions#join
- Du kannst entweder die letzte Regel nehmen - wenn sonst ausgegeben wird, dass Alle Fenster geschlossen sind
- oder falls Du keine Ausgabe und die letzte Regel nicht brauchst(falls alle Fenster geschlossen sind) wünschst kannst Du auch einfach das Ergebnis weitergeben
Dann brauchst natürlich auch die eckige Klammer nicht, wenn nur ein Element vorhanden ist.

@mickym perfekt - eine letzte minimale Optimierung ist mir gerade noch aufgefallen...
Ich habe zwecks Organisation und Übersicht bei meinen Zigbee Kontaktsensoren im Namen immer Contact mit am Schluss stehen. Das hätte ich in der Aufzählung gerne entfernt - wie bekomme ich das noch integriert also ->
friendly_name.slice(0, -8)Wenn ich das direkt dranhänge
payload.*[payload.contact=false].item.friendly_name.slice(0, -8)~>$join(", ")bekomme ich einen Fehler
Invalid JSONata expression: Attempted to invoke a non-functionKann ich mich für Deine Hilfe irgendwo mit einer Kaffeespende revanchieren?
Danke & Gruß -

Danke & GrußNein - brauchst Du nicht, mache ich gerne
In JSONATA machst Du das so:
payload.*[payload.contact=false].$substringBefore(item.friendly_name," Contact")~>$join(", ")

Falls Du zigbee2mqtt verwendest, was Du auch tust - soweit ich mich erinnere, kannst Du als friendly Name auch Hierarchien bilden und dann brauchst Du diese Konstrukte mit den Namen nicht.
Also einfach die Gerätenamen entsprechend mqtt topics in der Hierarchie benennen:
Im friendlyName wird das mqtt topic dann entsprechend eingetragen:
-
@mickym Vorteil für Dich ist, dass Du diese Nodes eigentlich dann nicht brauchst, sondern über die mqtt Hierachien selektieren kannst.
In meinem Fall selektiere (subscribe) ich alle Kontakte mitzigbee2mqtt/kontakt/#
