Hi folks,
I am trying to read the brightness level of one of my Hue Lights, and change it's color based on the value, but I'm struggling with the basics.
Is anyone able to tell me what I am doing wrong with the following flow? My first debug is only receiving a 'on' value.
```auto

Check the "green" change node, compare it to the red one.

I'm not sure I follow.
the change node isn't having the problem (I think). It's not getting past the switch

Well it does if you compare the 2.
But indeed it is not relevant to this issue then.
What debug output do you get from the api node (or whatever it is, i don't have it installed) - use 'complete msg object'

All I get is "On"

So with a debug node set to Show Complete Message all you get is "On". I find that very odd. Can you post a screenshot showing that please?

my mistake, I did not have the complete message selected for that debug node.
I seem to be getting what I need now, thanks
