I am completely new to node-RED, evaluation if we could use it, but finding a very simple task too frustrating for me and do not find any good examples. The task is, 4 sliders and getting them into function node so that their values can then be further processed and result with some other data pass…

Link slider1 to its own change node. In the change node, set flow.slider1 to msg.payload. Repeat for slider2, slider3 and slider4 Then use a button and link that to a function where you can get all 4 values from flow at once & put the values into and array (or buffer). Then link the function to a …

Here is an example using the join node. The injects are for testing and generate a random number, Have a play hope it helps. [{"id":"c80bbf28.a5eed8","type":"inject","z":"5a245aa1.510164","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay"…

Thanks a lot E1cid, that is exactly what I needed. Still a question about the sliders, is there a way to configure individual colour for each of them?

[image] Garug: is there a way to configure individual colour for each of them? There are a few threads on the forum eg... [image] Horizontal color slider Dashboard Not clue what you have tried. Very messy. May be that way it will be simpler ... [{"id":"bdc44b29.79…

the Join works great to Join one or more sliders to function and access the values in function, but have now case where I need just 1 slider into function, but after an hour trying the frustration is too big and feel so stupid. I just do not sucseed on that or find answer and have tried so many thin…

This is what I have now, this works, but there will be many more sliders that update fast. I woull like to connect the sliders directly to LVZ ID functions to reduse data flows and wiring. [{"id":"b09033c8.c730f8","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"5a75194f.6c0a3","typ…

[image] Garug: There must be a way to get a single slider into a function without the Join? The built-in help for slider says... [image] If you add debug nodes to the output of things (sliders) you would see this [image] So in your function... //the LVZ message data // CHANGE THIS ... …

Thanks Steve, This was one of the first things I tried var DataIn = msg.payload; but now realise the problem likely was not getting the data in, but the data out, as it seems the data that is inputted affects the outgoing data construction. This is probably the solution and will try it a bit la…
