Hi,
is there a sensor available that works on Zwave that can measure the strength of the ligth outside?
I want to use this to lower our rollers in the house.

When i use the sunset, this is to early for us, as it is still clear outside.

Or is there another solution for my 'problem'.

Thank you in advance.

Wel, the motion sensor from Fibaro has an illumination sensor.
Use a calculated outside lux sensor. Script is available here on the forum.
Combine previous sensor with a 2nd script that gives you azimuth angle of the sun. That way you know from which angle on the sun is able to reach the room in the first place.
