Yes, I'm using a custom-made circuit that uses the output of a solar panel to determine the outdoor lighting conditions. I added that sensor after finding out that the calculated sunset/sunrise times were not accurate enough to control our window blinds (e.g. when it is very cloudy compared to a cloudless day).

More info on that sensor is here:
