Hello, i'm trying to handle with messages that comes in parallel to subflow. Here is exmaple [image] 4 messages comes at same time to one subflow. I would like to make a delay for messages. For example 1 messag in 3 sec. [image] [image] But in this case all the messages comes output of subl…

Yes, those are the link nodes I am referring to. This guide explains the differences between subflows and link nodes - https://nodered.org/docs/developing-flows/flow-structure#making-reusable-flows

[image] ThisisIO: 4 messages comes at same time to one subflow. At the moment, you have four separate instances of the subflow. That is not the same thing as having one instance of the subflow handling multiple messages.

[image] ThisisIO: How to change the to one? Each time you drag a copy of the subflow into the workspace you are creating a new instance of the subflow. If you only want one, then you should only have one subflow instance in your workspace.

If it is not possible? No way to solve it? The messages comes from different flows...

It sounds like you want to have a flow that is called from multiple places. One option would be to use Link nodes to pass messages from your different flows to the flow you want to handle the messages - and not to use Subflows which aren't designed for this scenario.

[image] knolleary: It sounds like you want to have a flow that is called from multiple places. Yes, you are right - like function. To make a queue for TTS Speaker. You mean these Link nodes? [image] ?It is like a shortcut for sublow?

Also maybe see https://flows.nodered.org/flow/cea8afa28b7a93ebdc0f Not a subflow but a simple queue for TTS example

Thanks i use exactly it! But as i said the problem was in multipy instances

[image] ThisisIO: as i said the problem was in multipy instances When you have multiple instances of a subflow then each delay node is a separate node, so each one limits the rate of output of messages passing through it, but as each one node sees only one message then the delay nodes have no…
