Hello, I use an inject node to send a message automatically at regular interval. My problem is that I want to let it passe the first message and then block (and unblock with conditions). I have the solution to block and unblock but I don't know how it's possible to check that is the first message. …

The inject node can be set to only inject once at start. Or is that not what you want ? [image]

Mmmh I think I've explained it wrong ! I want to inject a message every 5 seconds but I want only the first message to go through and then with a function I block it from being sent until a condition I have chosen unblocks it (to do this I have used a function node). Basically I inject at regular …

And then when it is unblocked it only sends one more ? or just repeats until something else blocks it ?

Both haha, it send one more and normally my function block it just after.

Is what you are injecting a constant value ?

Yes, I inject a msg.payload and a msg.topic (their values is "test"). I give you the flow if you want to see it. [{"id":"cedf6ac1.bc7a48","type":"tab","label":"Request/Reponse co m1","disabled":false,"info":""},{"id":"a4a9d05f.526ca","type":"change","z":"cedf6ac1.bc7a48","name":"","rules":[{"t":"s…

OK - so that seems to work for me... or at least as far as you have described it... the top inject sets up the block - then the other unblocks it and shortly after the repeat on the top re-blocks it ? Is the problem that while unblocked the lower (unblock) path can send several messages ? - but the…

The problem is that the inject is useless here because it doesn't send anything, it just allows the function to be blocked, but I would like the first message to go out BEFORE the function is blocked. I don't want it to be used only to block the function permanently, but to send a first message, th…

I would use a rbe node instead and use msg.reset to unblock it... [{"id":"a4a9d05f.526ca","type":"change","z":"cedf6ac1.bc7a48","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"test","tot":"str"},{"t":"set","p":"topic","pt":"msg","to":"ok","tot":"str"}],"action":"","property":"","from":…

Ok but the stream doesn't work (or doesn't do what I want it to do, it's ultimately the same problem), and the rbe node isn't connected to anything related to the sms out node so I don't understand what you're trying to do (and I'm really new to this language so it's taking me a while to understand)…
