Injecting user selection into the payload

General

I'm trying to make a Celsius / Fahrenheit dropdown setting which then changes the gauge. I'm still learning here but I understand objects, just not necessarily JScript.

What I have now I cannot get the setting properly in the function node to use it.

This is what I have so far. The first gauge works fine reading from my temp sensor. The test one I wanted to change based on the setting.

Hi,

really close :-)... as each event is separate you need to store the "other" value in context while you wait for the value to arrive... - so for example store the f/c select - then use it when the temperature arrives...

here is my simple version of yours, without the ds18b20 node which I don't have... but you will get the picture

Thank you for the help.

I tested your solution but it doesn't change the test gauge as it's still showing the Celsius value even when injecting "20" again when set to Fahrenheit.

The function that @dceejay provided you, showed you how to do the bit you were stuck on.

I would hope that you can do the other part of the function where the temperature isn't set to f
