Hmm, not sure what you exactly mean. I think this has something to do with the things created by the hue binding. It seems, if I take a look at the “Code” tab page, that the ledindication has a value of 16000. This one is shown at the “Thing” tab page for “Dunkel-Schwellwert”. Sounds a bit, that here is a type mismatch in the binding itself?
Here some screenshots to show what I’m talking about. May be this helps to find the problem:
