Continuing the discussion from Bloomsky Weather Station:
If the Aeon Multi sensors aren’t a good option for you, I would suggest getting one of the Fibaro Motion Sensors and placing it inside, but pointing directly out a window. Motion detection won’t work through glass, but the illumination sensor will. Users have reported that the illumination sensor has a wider dynamic range than the Aeon.
There are good community-supported device handlers for this one.
