Hello - I wanted to see if I could use the "complete" node to monitor when certain events in the flow are done (basically, monitor when any branch of a flow ends). When I look at the nodes that can be selected in the "complete" node, I also see the subflows (which is great!)

 ![Screen Shot 2021-07-27 at 5.40.16 PM](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/4/141eda45e80ce98c120e3a6acb7d966b50e035b1.png)

The question is when does the complete node get the notification for sub-flow completion? The last "node" in both sub-flows shown above is another sub-flow (which has just the Pushover node). Also, if a node shows up in the selection list for the "complete" node, does it mean that it automatically supports notification?

I did do a Google search and also search here, but as you can imagine, the search results were somewhat meaningless. There was one example of using a complete node but it was very basic.

Thanks for your help.

Does the Complete node ever signal if it is connected only to a Subflow?

I will create a small test flow and see what happens..

Just created a small test flow and the complete node never gets a notification when the subflow completes. Oh well - back to the drawing board...

I suspected not. One solution may be to add another output to the subflow and send a message to it when the action you want to perform is complete. If appropriate attach a Complete node inside the subflow to the relevant node and send that to the additional output.

This question was in relation to the other topic that we were discussing. Originally, I had thought of using the complete node to reset the GV but it was simpler with the link nodes. Thanks again!
