A Home Assistant Schedule helper can tell an automation when a weekly time block is active. Creating the helper alone does not switch on a lamp or any other device.
Test the time block by itself
Create a short window for the current day and watch the helper before, during and after it. Home Assistant documents the helper’s state as on inside an active block and off outside. If the state never changes, check the selected day and time before investigating the lamp or buying replacement hardware.
Test the action separately
For example, if a lamp should turn on at the start of an evening block and off at its end, define and test both actions. If the helper is on but the device stays off, try direct control, then inspect the automation trigger and action. Use a nonessential lamp for the trial so an incomplete test does not interrupt anything important.
