Hello, Hopefully, I can explain my issue. Please feel free to ask any questions. I'm migrating millions of files from one volume to another. However, it's not a straightforward bulk copy of a file. The file's destination is based on data; the destination is dynamic based on the values. Also, I'm…

I will do my best to post the solution that worked for me; I cannot post the entire flow due to security, and the client is well-known. I have extracted the parts needed to manage the queue. [Screenshot 2025-04-24 at 9.57.29 AM] [{"id":"aa8e7807a8849bbc","type":"inject","z":"47d7ef94526cd759","na…

I don't think this is going to work for my issue I have installed node-red-contrib-home-assistant-websocket through the pallete There is no remove button? How do I remove it, thanks. Figure it out, I had to delete the server node, then the remove appeared.

Ok for clarification, I don't think I have skill set to get this to work. From what I can see, it looking for triggers from automation, I could not figure out how to make it watch a exec node.

All you need is to know when it has finished so that you can release the next one.

OK, so I'll point out the rather large Rhino in the room. Why are you using Node-RED for this task? There are far better tools for this kind of thing.

Trust me, with the complexity around this project, there is no better tool. Each file needs to be evaluated and different routes taken.

I think I have found the solution, testing is positive node-red-contrib-queue-gate [{"id":"a46ee04e.b1a9b8","type":"inject","z":"e5c32195.7ce7b8","name":"open","topic":"control","payload":"OPEN","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":170,"y":80,"wires":[["c54…

I'm sure it will work with a message queue gate. Isn't it better not to repeat the inject? Since the exec node returns the command's exit status as msg.payload.code, you could use that to trigger the next process loop. [image]

You're correct, I'm not repeating the inject node. I have replaced the delay node with the queue gate node. The gate node is in queue mode, the inject runs at intervals, if the gate queue is less than 5,000 queued, it will add to the queue. Once the queue is at 5,000 it will drop the rest and they…

The simple flow described in this post shows how you can easily make the operations happen sequentially, not starting the next one until the previous has completed.
