The Usage Limit Rule allows you to specify how long an appliance--such as a TV--will be allowed to stay on.
Want to limit how much TV the kids watch after school?
Assign a Usage Limit Rule that turns the TV off after 2 hours.
** Don't want to interfere with your own late night TV viewing?
By default, the Usage Limit Rule applies to an entire 24-hour period, but you can also define what time during the day it is active.
So setup the 2 hour limit to apply only between the hours of 4PM to 8PM each day, and after the kids are in bed you can binge-watch to your heart's content.
