SetupIdle takes indeed a delay value in milliseconds. Once you called
it, the system will call viewIdleScript method of the frame (it has
to be a view and be open). viewIdleScript returns the number of
milliseconds before being called back.
Therefore, if you something to be done periodically (while the view
is open) and the first period to happen immediatly, doing :SetupIdle(
:viewIdleScript() ) is a good option.

This is a way. However, if the Newton doesn't go to sleep at 3 AM, it
is because of a problem and I'm not sure you would be able to put the
Newton to sleep. Moreover, since you're not using an alarm, I'm not
sure the Newton will be waken up to run your idle script.

You need to be sure that your view is open, otherwise the idler
object is killed.
I don't really understand what your checkPower method does.
Additionally, you probably want to sleep until next day, 3 AM and not
for one day (it will be less the first time you run it).
