Hi @Herbert

Sorry - I can't quite decipher what you need.
I don't use the cronplus, but I can see from the export it outputs a payload of (example)

{
  'A' :20,
  'B' :25
}

If you wanted that to become the below for the next Node...

{
  payload: 20
}

You need to switch around your change Node (you have it the other way)

Apologies if I have this wrong

You were right.Thanks for your quick feedback.

:hugs:

I reed from the other topics it right, but I confised to write the correct text (payload.A) in right line.
I didn´t find my mistake.

Again THANKS and have a NICE day :wink:
