Quite simple: msg.payload.inputList = inputNumber;

Mozilla Development Network is the reference.
W3school is easy, fast and simple.

Hope it helps

Especially the part about messages in the user guide. Some valuable tips in there.

OK so you mean something like that? if (risingEdge) { return msg.payload.inputList = inputNumber;}
than this will happen "TypeError: Cannot create property '_msgid' on number '1'"

Thanks also to Steve-Mcl
appreciate that!

with that construction you are returning just the inputNumber... you need to return the whole msg object... so maybe

if (risingEdge) { msg.payload.inputList = inputNumber; return msg; }

or if you really just want the number

if (risingEdge) { msg.payload = inputNumber; return msg; }

Hello, now I want to detect falling edges of my inputs too. For rising edges this code:

const risingEdge = actualValues.reduce((acc, value, index) => {
if (value && !previousInputs[index]) inputNumber.push(index + 1);
return acc || (value && !previousInputs[index]);
}, false);

works totally fine.
What would I have to change now?

Thanks in advance.

If you want to detect rising edges and falling edges then you just have to look for a change. Feed the value through an RBE node and whenever you get a message then the value has changed. If you need it only when it has changed by more than a certain amount then the RBE node will do that too.
