If you want to send each one of those values in the array out of a different output then you can use a Function node with the number of outputs set to 8, containing something like // payload contains an array of values, build an array of messages containing those values let msgs = msg.payload.map(m…

Also, posting a screenshot of a function is not helpful. Please copy and paste the code into your reply and put ``` before and after it on newlines. As I said before, you need to describe the behaviour you are seeing. Don’t assume we can figure it out from a screenshot that doesn’t show your flow a…

Below is the function code var msg5 = msg.payload.Value.map(function (p) { node.send({payload: p}); }); return msg5; I am not clear with this function body…how the 5 array values gets separated ? & what will be the output msg property?

You should make set to: msg.payload msg.payload.value or directly on the gauge {{msg.payload.value}} without this change node Regards

This also not working [image] the value is not linked to gauge value
