A fixed Kasa schedule is the better starting point when a lamp must turn on at a known time. Away Mode serves a different goal: switching at varying times during a window.
Set one goal for one outlet
TP-Link distinguishes Schedule, Away Mode and Timer in the Kasa app. If you need light at seven every evening, test a fixed schedule; if you want varied activity during an evening window, test Away Mode on a compatible lamp. Verify that the lamp returns to light when power is restored through the plug.
Verify before depending on it
Use a short test window while you are home. Note the device’s time zone and day settings and avoid stacking an overlapping fixed schedule during the test. If you need the lamp reliably off at a particular time, prefer a schedule you can verify. An automation is not a substitute for home security.
