I have open weather map showing a temperature gauge on my dashboard, brilliant!

How do I get a hue bulb to respond to the temperature figure deg C., and change colour accordingly?

Thank you.

First figure out how to control the hue bulb itself. I don't have one, so no can help there, but I think there are hue nodes you can search for.

Then if none of them also supply temp to colour, use a `switch node` with the various settings to chose the output. Or a `function` node with some code to do the same, possibly with `if()`
