OctoPrint

Wenn ich das OctoPrint Plugin aktivieren möchte, bekomme ich die Meldung, dass “Is Online” unbekannt ist.

Was mache ich da?

Dieser Knoten ist ein Typ, der Ihrer Installation von Node-RED unbekannt ist.

EDIT:

Installieren von ‘node-red-contrib-isonline’

dd_internetagentur

dienire Sorry, vorher war die Node “IsOnline” im Core mit drin und erwähnt, wurde aber dann im Core selbst implementiert und natürlich in den einzelnen Flows wie z.b. der jetzigen Überprüfung des Octoprint Servers dann vergessen mit einzutragen ;-) Wird aber nachgereicht. Und super das du es auf anhieb sogar selbst gefunden hast ;-)

dienire

Alles klar, verstehe.

Und was muss ich tun, damit der OctoPrint Server Status auch auf der Uhr angezeigt wird? 😅

dd_internetagentur

dienire den API Key bei Octoprint raussuchen und unter “Get Job State” Node die IP von Octoprint sowie den API Key eintragen ;-)

dienire

dd_internetagentur Hab ich gemacht, zuvor auch die IP bei “is online” eingegeben, aber bisher rotiert lediglich die Uhr auf der Uhr

dd_internetagentur

dienire Hast du den ScreenNamen aus der Screen Init in der Playlist eingetragen ? Schau dazu mal bei der CORE Node dort gibts ein Playlist Flow als beispielt, wie man eine Playlist erstellt, die dann abläuft.

dienire

dd_internetagentur Ich habe noch gar keine Playlist gemacht. Weiß überhaupt nicht was ich da machen muss, um entsprechende Sachen hinzuzufügen.

dd_internetagentur

dienire Schau hier nochmal rein: https://wiki.dietru.de/books/pixel-it/page/core-elemente

Dennis hat das grad nochmal etwas verständlicher aufgebaut mit der Playliste.

Die Playlist geht dann an das Node “Playlist Updater”

dienire

dd_internetagentur So ähnlich hatte ich mir das auch schon zurecht gebastelt.

Aber wie bekomme ich da jetzt z.B. OctoPrint und die OpenWeatherMap bei?

dd_internetagentur

dienire Also du hast ja bei dem Flow für Octoprint und OpenWeatherMap die “Screen Init” in dieser trägst du den ScreenNamen ein wie z.b. “Octoprint”

Diese ScreenNamen müssen in der Playlist angelegt werden, klicke diese Doppelt an dort siehst du den aufbau wie z.b. so;

[
    {
        "screenName": "internal_clock"
    },
    {
        "screenName": "weather_temp"
    },
    {
        "screenName": "weather_wind"
    },
    {
        "screenName": "weather_humi"
    }
]

Hier steht dann die Reihenfolge für die angezeigten Screens. Danach einmal kurz den Instant Nippel bestätigen und die Playliste steht fest.

dienire

Habe das aktuell so zusammen gebastelt, keine ahnung ob das überhaupt richtig ist und sinn macht!?

dd_internetagentur

dienire also die Grauen Nodes sind “Links” diese machen eine unsichtbare Verbindung zu einem anderen Node.

Wenn du einen Link anklickst sollte eine gestrichelte Linie z.b. Richtung “Pixel It Screen Data Update” gehen damit der Core am ende überhaupt weis was er anzeigen soll.

Falls die Links nicht gesetzt sind kannst du diese auch anhaken oder direkt verbinden. Jeder Nebenflow sollte einen Link richtung Update oder Alert für eine sofortige Anzeige haben.

So sieht ein verbundener Link aus:

dienire

Könntest du mir ein Beispiel mit OctoPrint oder der Color Change Clock machen? Viellecht verstehe ich die sache dann ein bisschen.

dd_internetagentur

Klar hier siehst du die Verbindungen die ein Link haben sollte für die Playliste;

dienire

Irgendwie ist das komplette Node-Red Zeug bei mir abgeschmiert, nachdem ich das so wie in dem Beispiel nachgebaut habe… :(

Auch ein Pi reboot bringt bisher keinen erfolg.

dd_internetagentur

dienire Okay ich schreibe dir ebend was zusammen.. kommt hier gleich als Edit wie du es wieder zum laufen bekommst ;-)

EDIT:

Also verbinde dich mit SSH auf deinen Raspberry PI

gehe in den Node-Red Ordner und such die Datei flows.json bearbeite diese.

cd ~/.node-red/

sudo nano flows.json

in dieser Datei wird am Anfang irgendwo ein “disable:false” stehen, ändere dieses auf “disable:true” und speichere mit STRG+C und dann mit Y bestätigen.

Starten jetzt deinen PI neu und öffne Node-Red, dein letzter FLOW sollte nun deaktiviert sein. Und du kannst nochmal probieren.

dd_internetagentur

Als Hilfe für dich auch nochmal den Flow zum Importieren:

dd_internetagentur Das hat funktioniert.

Nachdem ich

rm flows_raspberrypi_cred.json

sowie

rm flows_raspberrypi.json

ausgeführt hatte, funktionierte Node-Red wieder.

dd_internetagentur

dienire Ja das geht natürlich auch, nächstemal einfach die json öffnen und das Disable:true setzen, dann ist die ganze Arbeit nicht gleich verloren ;-)

dienire

dd_internetagentur Okay, vielen dank. Wodurch kam der fehler?

Hab damit auch mein locales Node-Red auf meinem Windows Rechner gekillt.. :(
