Hi to All

I have various thermal sensors on a plate. I would like to change the gradient depending on the measured value in real time.
How can I do this?

The property value takes a string variable, but I think if this is a number then it may have to be a decimal number (i.e. instead of "FF" you should use "255").

Also, if you just want to change one side of the gradient, consider the "SetColor" function instead of "SetProperty" as that gives more control.

See attached.

Hi Steve

It's working nice.
Only the flame is red on the outside and blue on the inside.
It should be the other way around. But I'll try to fix that.
Here the result:

I suspect the string is not hex..
