Inject 20 times with 1 sec intervals

General
1

Is there a way to trigger an inject 20 times with 1 sec intervals?

2

yes.

One way...
inject node set to repeat every 1s → function node (write for loop calling node.send(msg) )

Another way...

inject node set to repeat every 1s & set to send a JSON payload of [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19] → split node

Sorry my bad, I made the question wrong

I meant something like this but 20 times

really still not clear.

Do you want

  • 20 messages spaced out over 1 second?
  • 20 messages sent as fast as possible every 1 second?
  • 20 messages 1 second apart? (only when triggered)
  • 20 messages spaced out across one minute?

The first one, 20 messages spaced out over 1 sec (when triggered)

looking at your picture

... it looks more like you want : 1 MESSAGE - EVERY 1 SEC

in which case this is better...

its basically the same but the rate limiter is set to release 1 msg every 1 sec

here it is via a function node...
