(Gelöst) Füllstände mit Node Red auslesen

[mickym]

@damrak2022 Nein - Du hakst in den Adaptereinstellungen an, dass Du den Palettenmanager installierst

und die SNMP Node installierst Du, indem Du diesen aufrufst

und dann unter installation, den Namen des Moduls eingibst:

und aus dem Homeverzeichnis des pi kannst Du alles wieder löschen - also das node_modules Verzeichnis und auch die beiden package.json und package-lock.json.

Und ich würde Dir empfehlen nicht einfach Installieren, damit "verhunzt" Du Dir nur Dein System, in dem Du Leichen erzeugst.

[Damrak2022]

@mickym Okay, das habe ich gemacht.

Wie lösche ich die von Dir genannten Dateien/Pakete? Mache ich das über das Terminal und wen ja mit welchem Befehl genau? Du hast recht, die größte Befüchtung ist das ich mir aus Unwissenheit meine Installation verhunze.

[mickym]

@damrak2022 Nun ja - nachdem Du das im Homeverzeichnis des PI gemacht hast gehe ich mal davon aus, dass das da drin ist. Also Terminal oder einfach ssh Verbindung aufmachen.

Poste halte mal das Homeverzeichnis Deines PIs:

cd ~
ls -la

[mickym]

@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",

@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?

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:

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.
