\nWer Kurse auch im NodeRed-Dashboard anzeigen bzw. umrechnen will, kann diesen Beispiel Flow als Template verwenden. <\/p>\n

Die Funktion ist schnell erkl\u00e4rt. Es wird nach der Eingabe des Bitcoin Wert (Achtung, kein Komma, nur den Dezimalpunkt verwenden) der Kurs bei Kraken abgefragt und der aktuelle BTC in Euro umgerechnet. Der Beispiel Button, im Flow, erzeugt z.B. den Wert f\u00fcr 1000 Euro. Kann ja leicht angepasst werden oder auch direkt vom Konto eingspielt werden, wie hier<\/a> schon mal gezeigt. …<\/p>\n
