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 KontextVergleiche führst du mit einer Switch Node durch.
