Fibaro Multisensor - Luminance value too low
I'm using a fibaro 4in1 multisensor. Seems to work with one exception.
It only reports very low luminance values, at the moment its sunny outside and it reports me a luminance of 18lux, that would be equal to the street lighting at night.
I already changed the luminance report threshold to 20lux. But if the range of lighning varies only from 0-18 I think I have to redude the value much more.
I'm confuses cause the sensor should be able to report values up to 10000 lux and not only 0-20.
How can I fix it to get the right values?
