Help with Custom SmartApp Code

My goal of the code below is to turn on a light when power consumption = 0 and between set times. As it stands, the code turns on the light when the power consumption = 0, but not within the specified time range. Looking at the code, it appears I need another If statement regarding the from/to time. Does anybody have an idea how to accomplish this?

I have not heard of CoRE when I posted it, but coincidentally found it. Just created a piston to do exactly what I wanted done. :slight_smile:
