## Basic Timing

The smart applet provides basic timing capabilities, supporting device timing and group timing. The device can be a Wi-Fi device, Bluetooth Mesh sub-device, or Zigbee sub-device. It also encapsulates the add, delete, modify, and query interface for the timer information of the device function (DP). After the App sets the timer information through the timing interface, the cloud module will automatically perform the reservation operation according to the timing requirements.
