Just keep it simple?
Use a switch Node, and only send delayable messages out the first pin, and for others, skip the delay?
```auto

What do you want to happen if there is a true message followed by a false one a minute later? Do you want the true one to be passed on after another 59 minutes (which is what your question says) or do you want the false message to cancel the delayed true?

i want the true message to be delayed, until the 60 minutes or false message is send.
also i think the tue and false needs te be set because the timer starts again if multiple true messages are send, or am i wrong about this?

So if a `false` message is received, you want that to bypass the delay, BUT in addition, release what is currently delayed?

sorry for the confusion.
- if true then delay 60 minutes.
- if false then reset delay and send false.
- if true is send multiple times stay counting down.
- if 60 minutes has pased then output needs to be true until false is send.

I think this may do what you want, though you still have not been clear.
1. If a false message arrives then it is sent straight through.
2. If a true message arrives then it will be delayed by 5 seconds (obviously change that to 1 hour for your requirement).
3. If a false message arrives while a true is waiting then the true will be cancelled and the false will be sent on.
4. If a true message arrives while a true is waiting then the second true will be ignored.

Good. For the future please note the detail in my description of what the flow does. It would have saved those here time if you had given a description to that level of detail when you asked the question. Thanks.

No worries, I'm new and have a lot to learn.
I find Node-RED difficult to program compared to CODESYS.
Thanks for the quick response.
