STEP BY STEPDiagnostic procedure
Follow the sequence and change only one condition at a time.
01
Confirm the clock, time zone, and schedule
Check system time, location, repeat days, and whether the automation or timer is enabled.
Step 01: Confirm the clock, time zone, and schedule — Cropped directly from this tutorial’s English main infographic.What to observeRecord the reading or behavior before changing the next variable.
02
Check power-retention behavior
Determine whether the controller keeps its schedule after power loss and whether the physical switch remains on.

03
Look for conflicting automations
Disable overlapping routines, scenes, or power-restore settings during the test.

04
Run the task manually
Use the app test or run-now function to confirm that the target light can execute the action.

05
Reconnect and save the settings again
Keep the device online long enough for the new schedule to synchronize.

06
Observe one complete cycle
Verify the light turns on or off at the expected time without another rule overriding it.

Expected result
The fault is isolated to a power source, connection, setting, controller, driver, or light section.
If the fault remains
Stop if there is overheating, odor, damaged insulation, repeated fuse failure, or exposed mains voltage.
