How to set the timing to manage the switch of the device?

After the device is added to the app, select the device to be set in my device and click to enter the device control page. If the device function supports timing, there will be a timing button on the device control page. Click to enter the time required for setting, the number of repetitions and whether to turn on the timing function. If you need to repeat, please enable repeat. To modify the set timing, just click the existing timing to enter the timing editing page.
