I would like to incorporate the Light reading into one of my outdoor lighting programs. I just don't understand how it really works. I've been checking it daily and the readings are so unreliable compared to what I see out the window. Has anyone been able to take use of the light function and if so, how?

None of my area stations report light data so I have not tried using it before. Depending on your application you may considered using the light sensor on the motion detectors to establish dark .

My area shows current light and light rate. Current light is never more than about 11% and that seems to be around 1:00pm if its very sunny. Its 0% up to about 9:00am in the morning and after about 5:00pm (in May). If its cloudy or raining, it shows 0%. I expect these readings are specific to my location's sensor or the location's station has the sensor inside or without a broad sky view. I don't think there are many applications for which this is a useful trigger. I agree with iostream that a motion sensor dusk trigger could be more useful and possibly more reliable.
