Can I have a device automatically turn off after a period of time?

Yes! Decora Smart Wi-Fi devices have an auto shutoff feature which is great for closets, pantries, and other loads that are frequently left on. The Auto Shutoff time can be selected within the My Leviton app under Settings for the respective device.

Choose the 3 dots [⋮] in the upper-right of the device card and then select Settings.

Now select Auto Shutoff and set a time for the device to automatically shutoff.  Hit save and you're all set.
