The scenario is:
Porch light defaults at 15% and turns on automatically at dusk.
If someone approaches the porch, the motion sensor fades the light to 100%.
If there’s no motion after 4 minutes (default reset time), the light fades from 100% back to 15%.
It works, but the “fade” is not as expected. Instead of a smooth fade, it does 3 stairstepped levels. Which function in CoRE will do a smooth fade?
