Spritpreise der letzten 3 Tage abfragen, ist das möglich?

du musst nur mehr den Datenpunkt mit dem Spritpreis ändern, und Datenbank und email konfigurieren.

Edith: Preis 0 gefiltert

[jensus11]

Wo fügt man diese Zeile ein?

[moebius]

node-red adapter installieren -> zeile kopieren -> bei node-red im menü auf importieren clipboard

Hallo Moebius

also ich habe den Flow importiert und alles soweit angepasst aber ich erhalte eine unvollständige

Email geschickt

> "Aktueller Spritpreis ****0**** - Kleinster Preis war ****0****, Durchschnitt 0.7369115128449051, Maximum 1.259!"

Warum sind diese Angaben leer. Habe ich was falsch gemacht?

[moebius]

@simpixio: wenn der aktuelle Preis 0 ist, dürfte was mit dem ioBroker input nicht stimmen. Die payload sollte den Spritpreis enthalten und nicht 0.

[Homoran]

Wenn die Tanke zu ist kommt 0!

Außerdem habe ich auch im Adapter immer wieder 0 wenn der Wertsich nicht ändert.

Da stimmt IMHO etwas bei der Auswertung der Antwort vom Tankerkönig nicht.

Gruß

Rainer

[moebius]

ok, falls 0 kommen kann, einfach mit einem switch node ausfiltern.

Werde den ursprünglichen Flow aktualisieren.

ich glaube da ist bei mir noch was verkehrt…. kann es sein das ich was falsch gemacht habe? Hier mein FLOW, vielleicht findest du da ein Fehler :lol:

hab nur persönliche Angaben entfernt!!!

[moebius]

@simpixio: du hast nichts falsch gemacht. Mein Beispiel hat nur nicht berücksichtigt, daß der Preis auch 0 sein kann.

Habe das Beispiel schon erweitert, oder du fügst selber einfach einen switch Knoten nach dem Input hinzu, der nur plausible Werte durchlässt.

[buzii12]

Wow, ein kompletter Flow, das habe ich nicht erwartet, DANKE moebius und pix. Ich kämpfe schon seit Tagen damit rum, habe es auch zum laufen gebracht aber nicht so elegant wie bei moebius.

Ich habe versucht den Flow zu importieren, bei mit kommt eine Fehlermeldung, dass der SQL Typ nicht erkannt wurde und im Flow habe ich ein Roten Node da steht "unknown: mySQL", hast du eine Idee wie ich das zu laufen bekommen?

LG

[moebius]

@buzii12: kein Problem, helf gerne weiter. Finde Node-red wird unterschätzt - so schnelle und elegante Lösungen schaffe ich mit scripts nicht…und ich bin auch erst node-red Anfänger.

Den mysql Knoten kannst du so installieren: Node red menü -> "Manage palette" -> Reiter "Install" -> "mysql" eingeben -> "install" beim mysql node.

[buzii12]

OK, noch mal danke hat geklappt, das ist echt cool.

LG
