Dear all,

I want to get the illuminance [lux] of a zone which depend on daylighting and on the lamp intensity. Unfortunatelly, there is no "illuminance at reference point" output. There is just a "daylighting at reference point" ignoring the light from the lamps. Do you have an idea how to calculate the sum of both light sources? In concrete I am looking for the value a real light sensor would measure at a reference point.

Thank you in advance! P
