Pro Schedules and timers work well
You can configure this switch to turn on and off whenever you choose. Schedules are useful for waking up in the morning and going to bed, and timers help expand that functionality to single-time usage. You can fully automate anything plugged into this switch, even when on vacation half the world away.
You can also enable 'away mode', which turns your lights on and off automatically simulating what it would look like if somebody were home. This deters burgles, as generally they try to break in when nobody is home.
