Input numeric data from Dashboard

Hello, can we use numeric Dashboard node in order to change settings into a node, for example change the delay of a delay node. Or is there any other way to do it without opening the node? Thanks

Did you read the node's Info tab?

Here's the basics how it can be done

[{"id":"b5de0f6b.8e304","type":"delay","z":"6d08d5ab.a8aa3c","name":"","pauseType":"delayv","timeout":"1","timeoutUnits":"seconds","rate":"1","nbRateUnits":"1","rateUnits":"second","randomFirst":"1","randomLast":"5","randomUnits":"seconds","drop":false,"x":460,"y":330,"wires":[["bf6c9dd9.528b3"]]},{"id":"9f0535bf.8fcbf8","type":"inject","z":"6d08d5ab.a8aa3c","name":"","topic":"","payload":"message","payloadType":"str","repeat":"5","crontab":"","once":false,"onceDelay":0.1,"x":270,"y":330,"wires":[["b5de0f6b.8e304"]]},{"id":"bf6c9dd9.528b3","type":"debug","z":"6d08d5ab.a8aa3c","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":540,"y":390,"wires":[]},{"id":"a7f10ff4.3a675","type":"ui_numeric","z":"6d08d5ab.a8aa3c","name":"","label":"numeric","tooltip":"","group":"d6060f19.2b834","order":0,"width":0,"height":0,"wrap":false,"passthru":true,"topic":"","format":"{{value}}","min":"1000","max":"10000","step":"1000","x":160,"y":270,"wires":[["8938fbca.942ca8"]]},{"id":"8938fbca.942ca8","type":"change","z":"6d08d5ab.a8aa3c","name":"","rules":[{"t":"move","p":"payload","pt":"msg","to":"delay","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":340,"y":270,"wires":[["b5de0f6b.8e304"]]},{"id":"d6060f19.2b834","type":"ui_group","z":"","name":"STAATUS","tab":"93443fe0.36117","disp":true,"width":"20","collapse":false},{"id":"93443fe0.36117","type":"ui_tab","z":"","name":"Home","icon":"dashboard","disabled":false,"hidden":false}]

Hello HotNipi, thanks for your reply.
I've been trying your flow but the "variable delay node" gets overide to it's default value each time i'm pushing the inject mode, see screen shot

As I said, example was to indicate basics.
What you'll need to do is to store the value from numeric into flow context (or global context if needed) and use it every time as last known good value for delay.
