hello, i have the intention to fill a chart with random data. it shall simulate if people done a task it appear in a chart. i have no sucecss with inject & delay node. (at least my chart looks linear slope) i need a trigger that send a message random between 1-10 minutes and after the delay it …

Nice, but I would suggest a reset input, just in case you don't really want it to run forever. [{"id":"81fa9f84.c2ef3","type":"change","z":"f3a075a0.2b2ae","name":"","rules":[{"t":"set","p":"reset","pt":"msg","to":"","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":340,"y":…

I just tried to stay in scope of issue. For full solution I think there is much more needed of course.

thanks for the reset hint. my current solution: [{"id":"3716c275.fcba66","type":"subflow","name":"jobs simulation","info":"","category":"","in":[{"x":100,"y":120,"wires":[{"id":"d8b4ec33.0ea608"}]}],"out":[{"x":1180,"y":240,"wires":[{"id":"b93c39d1.206018","port":0}]}]},{"id":"b93c39d1.206018","t…

In case anyone is still interested, this flow will generate the sort of random events that @MarkusR wants, using only a single function node and no feedback loop. It also illustrates what a pain JavaScript can be (at least for me) when what you want is synchronous execution. I was already working on…

Here is a way of refactoring the loop to make it a bit neater. [{"id":"f6d5dfd7.84ec5","type":"function","z":"6dc690a3.1abc88","name":"","func":"const minDelay = 1, maxDelay =5; // seconds\nvar run = context.get('state') || false;\nif (msg.topic.toLowerCase() === 'control') {\n run = ! run;\n}\n…

[image] drmibell: ... but if anyone can suggest less ugly code I would be grateful. You could use a dsm node: [{"id":"a26cd0b7.90aef","type":"dsm","z":"66646ca8.e97654","name":"random trigger","sm_config":"{\n \"currentState\": \"stopped\",\n \"states\": {\n \"stopped\": {\n …

@Colin , thanks! That certainly is neater -- and just the sort of help I'll need if I am ever going to get really comfortable with JavaScript. I have coded in at least a dozen high-level languages since the mid-1970's, and JS may not be the most difficult or opaque, but somehow I find it the most ann…

@cflurin That's a really nice solution to the problem. At one time, finite state machines were my bread and butter, so I've looked for opportunities to use your node. Unfortunately, I haven't done much with it for a couple of reasons. One is the learning curve associated with the JSON objects used f…

@drmibell : Thanks for your feedback, your answer is dsm specific, so I moved to node-red-contrib-dsm Node-red-contrib-dsm
