Dim by 10% doesn't do dim by 10%?

Hi All,

I've got a setup that the lights will dim from 100 to 0%.
With timers that will dim the light by 10%.
But if you look here: it doesn't dim properly by 10%? It jumps from 60 to 51?
Anyone has any idea?

Regards

I suspect that the device you're dimming doesn't maintain the internal power level in an even 100 increments. Probably more like 128 or 256. So at some point you get a rounding error that causes the reported value to be off by 1.

Z-Wave brightness is on a scale from 0% (off) to 99% (full on), so Indigo scales 0 to 100 to fit into that range.
