Advanced - Random Timing

Function Introduction

The light-watching function will simulate the scene of someone at home by randomly turning on and off the lights during the set time period, which plays a role in preventing theft.

  • Some parameters are explained as follows:
  • Repeat cycle: used to set a single turn-on or a cyclical turn-on. Select any time from Monday to Sunday, and the task will be repeated at the corresponding time; if no time is selected, the default is a single turn-on, and the task will automatically turn off after one execution
  • Custom color: used to customize the light status when the light is on during the execution of the light-watching function
  • Usage example:
  • Set the task time to 6:00 pm ~ 12:00 am, select the rest days Saturday and Sunday, and turn on the light-watching function. The light will automatically turn on and off randomly from 6:00 pm to 12:00 am on Saturday and Sunday to simulate the scene of someone at home.

Position 1 means it is effective on the same day. For example, 0x42 means that the task will take effect on Saturday and Monday (note that the corresponding task switch must be turned on)
