I have several of the Smart Home WiFi Outlet's (HS105) that allow me to set a schedule event tied to sunrise or sunset.  I can also set the event to a number of minutes before or after sunrise/sunset.  This is a very nice feature, and resulted in the purchase of several Outdoor Smart Plug's (KP400).

The Outdoor Smart Plug's don't appear to allow you to set an offset from sunrise/sunset, or at least I can't figure it out.  Their schedule event page looks different from that of the HS105's.

How do I set an offset with the outdoor plugs?

This is the schedule screen of the HS105, allowing an offset:

This is the schedule screen of the KP400, which does not appear to offer an offset:
