@mickym sagte in Füllstände mit Node Red auslesen:

@damrak2022 Ja wie befürchtet.

Also das node_modules Verzeichnis löschen und die package-lock.json

rm -R node_modules
rm package-lock.json

dann nochmal prüfen, ob das weg ist mit ls -la

@damrak2022 Ok dann ist das wieder sauber und die snmp Nodes sind installiert. Nun musst Du aus dem Thread den ich Dir gepostet habe, den Flow importieren.

Ich stell ihn Dir hier nochmal rein:

Also den Code über Select All markieren und in die Zwischenablage kopieren.

If _true_ the monitoring starts, if _false_ the monitoring stops.\n\nIn addition the IP-address has to be provided by `msg.host` or specified in the node in the environment variable IP Address.\n\n`msg.payload` on the output is monitoring status of the node (_true_ or _false_). If the printer is offline, monitoring is stopped automatically and has to be manually restarted. \n\nIn addition to the monitoring status, the status is published in a `msg.printer` object.\n\n{\n    \"pages\": 0,\n    \"status\": {\n        \"device\": \"\",\n        \"printer\": \"\",\n        \"since\": \"\"\n    }\n    \"cartridges\": {\n        \"percent\": {\n            \"black\": 0,\n            \"yellow\": 0,\n            \"cyan\": 0,\n            \"magenta\": 0\n        }\n    }\n}\n\n# SNMP Printer MIB\n\n**Voraussetzung ist die Installation der snmp Nodes: [node-red-node-snmp](https://flows.nodered.org/node/node-red-node-snmp)**\n\nDie Node bzw. Subflow wurde mit einem HP Printer mit 4 Tintenpatronen getestet. \n`msg.payload` muss ein Boolean/Logikwert sein. Wenn _true_ dann startet das Monitoring, if _false_ stoppt das Monitoring.\n\nZusätzlich muss die IP-Adresse des Druckers in der Eigenschaft `msg.host` mitgegeben werden oder kann über die Umgebungsvariable IP Address in der Node mitgegeben werden.\n\nDie Ausgabe der Node in `msg.payload` entspricht dem Status des Monitorings (_true_ oder _false_).\nWenn der Drucker offline ist, dann stoppt das Monitoring automatisch und muss manuell wieder gestartet werden. \n\nZusätzlich zum Monitoring status, wird der Status des Druckers im `msg.printer` Objekt ausgegeben.\n\n{\n    \"pages\": 0,\n    \"status\": {\n        \"device\": \"\",\n        \"printer\": \"\",\n        \"since\": \"\"\n    }\n    \"cartridges\": {\n        \"percent\": {\n            \"black\": 0,\n            \"yellow\": 0,\n            \"cyan\": 0,\n            \"magenta\": 0\n        }\n    }\n}\n",

Dann über den Import in das rosa Fenster kopieren:

@mickym kay, habe ich gemacht - sieht bei mir so aus:

Ist das korrekt?

Danke für Deine Hilfe. Gerne hätte ich auch Deine Grafik mit den Wellen, die sieht spitze aus.

[mickym]

@damrak2022 Wunderbar, dann machst Du die Node auf und trägst dort die IP Adresse Deines Druckers ein:

Das mit der Grafik geht nicht - da ich das NodeRed Dashboard nutze und Du nutzt vis - aber lass uns erst mal schauen, dass es läuft.

Wie gesagt mache die Node auf und trage dort erst mal Deine IP-Adresse ein.

[Damrak2022]

@mickym Okay, da stand schon die IP meines Raspi drin, Ist das richtig, das ich die jetzt auf die IP des Druckers geändert habe, oder war ich da wieder zu schnell?

[mickym]

@damrak2022 sagte in Füllstände mit Node Red auslesen:

@mickym Okay, da stand schon die IP meines Raspi drin, Ist das richtig, das ich die jetzt auf die IP des Druckers geändert habe, oder war ich da wieder zu schnell?

Nein das war richtig. - Da muss die IP Adresse des Druckers rein.

Nun importierst Du noch diese 3 Nodes und verbindest sie wie in dem Bild:

@mickym

Wie bekomme ich das "false" unter "SNMP"?

[mickym]

@damrak2022 Sehr gut - solange Du die blauen Punkte hast - musst Du oben rechts auf den Deploy Button drücken, damit das übernommen wird.

Dann machst Du das Debug Fenster auf (wie auf Abb. - die Wanze, Käfer .. ) und startest den Flow mit Druck auf true.

Dann machst Du die Nachrichten auf und schaust mal, ob die Druckerdaten raus kommen.

[mickym]

@damrak2022 sagte in Füllstände mit Node Red auslesen:

Wie bekomme ich das "false" unter "SNMP"?

Mit true startest Du den Flow im Moment, mit false stoppst Du ihn wieder. Aber erst müssen wir mal schauen, ob wir die Daten überhaupt abrufen können.

[Damrak2022]

@mickym Ja, Daten kommen

[mickym]

@damrak2022 Nee da ist noch ein Fehler drin. Klapp mal die Nachrichten auf und schau mal was für ein error kommt. Der Status der SMNP Node sollte auch den true status haben und nicht false, da sonst ein Fehler aufgetreten ist.

[Damrak2022]

@mickym Sorry, wo mache ich die Nachrichten auf?

[mickym]

@damrak2022 Auf die kleinen Pfeile neben dem Werten klicken.

Hast Du auch auf den true und nicht auf den false Button geklickt?

[Damrak2022]

@mickym Ja, true habe ich gedrückt und das ist die Ausgabe:

[mickym]

@damrak2022 Ja machst Du bitte mal alle Pfeile auf, dass man lesen kann, was unter error drin steht usw.

[Damrak2022]

@mickym Sorry, hatte ich übersehen

@damrak2022 OK dann funlktionieren bei Deinem Drucker die OIDs anscheinend nicht.

Dann müssen wir das halt manuell machen.

Schreibst Du mal die OIDs auf, mit denen Du die Daten erfolgreich mit dem MIB Browser ermitteln konntest?

[Damrak2022]

@mickym Dazu muss ich was sagen. Bei der ersten Einrichtung über snmp habe ich einfach die OID`s genommen, welche bei den Farben dabeistanden.
Mittlerweile sieht es so aus:

Das ganze Drama fing ja erst an, nachdem ich die Magenta Patrone gewechselt hatte. Vorher ging das.

Vor allem steht da kein Wert mehr. Es gibt zwar andere ID`s welche, dem Füllstand entsprechen, welche der Drucker anzeigt, aber das wäre ja mehr geraten
