I would like some code to run as soon as light comes above a certain level.

But to save battery I would like to do that with setWatch, is that possible?

Hi,

It's a nice idea, but I'm afraid it isn't possible... At least at the moment reading from the light sensor requires an analog to digital conversion, which can't be done without waking the device up - and if it's awake it's not that painful to get JS to do the reading for you.
