This requires a Dark Sky sensor with the condition
precip_intensity that tells if it’s raining or not. You could also experiment with other attributes such as
Turn on a light in the living room when it starts raining, someone is home, and it’s afternoon or later.

And then of course turn off the lamp when it stops raining but only if it’s within an hour before sunset.
