In my area, Echeveria nodulosa likes lots of bright light, but I try to shelter it from our intense sun during our hot dry days. It goes on active growing mode here during our cooler periods, between 65F and 80F. Watering-wise, I keep it on the dry side, and if I water I do it early in the day, not at night. My location has very poor humidity levels, so see also how your humidity levels are, and adjust your watering accordingly. Most succulents do not enjoy being in too humid conditions unless they are the tropical kind.
As with most of my succulents, I keep it in a well draining media, adding more pumice to the cactus soil I get from the big box stores. I usually get a bloomstalk during Spring time here. I have also seen how they really do well when I put some chicken grit (insoluble crushed granite) as top layer, helps the base of the plant and the lower leaves not sit in too much moisture in case it rains.
