Better join node?

Hellis81 · February 21, 2022, 7:02am

I’m looking for a better way to join messages than the standard join node.

I’m trying to make my software multi press be more responsive.
When I use the join node I set it up like this:

I expect a maximum of three button presses and you get a total of two seconds (I have a two, five and thirty-two year old that can’t press faster) to do these three button presses.
This also means if I only press once, it takes two seconds for it to react.

What I would want is something like the trigger node where you can extend the delay with each message that arrives.
That would mean I could probably set it to 0.5 or 0.7 seconds and it would be much more responsive.
Does this dream join node exist? Or does anyone have a way to make it more responsive?

I found a post on node red forum that is exactly what I need:

Now that I’m home I have tried this method for real and it works really well.
Made a slight adjustment to the code to get the count as separate outputs.

Single or double click:
