      Hallo zusammen,

      ich möchte gerne in NodeRed 2 eingehende Werte (aus 2 verschiedenen Nodes) miteinander vergleichen und, wenn sich diese unterscheiden den Wert aus dem 1. Node ausgeben / weiterverarbeiten...

      Wie kriege ich das hin ?

        @geforce28 du hast 3 Möglichkeiten:

        1- du holst dir beide Werte in ein Nachrichtenobjekt:
        1.a. Via iobroker get nodes
        1.b via join node
        2. du speicherst mind. 1 Wert in einem Kontext

        Vergleiche führst du mit einer Switch Node durch.
