Standard and custom function Standard function: refers to a template library of standard data points DP. It provides the definition of common features for more than 1000 product categories.

Function definition is the first step in product development. It consists of standard function custom function and cloud function. Standard Functions Standard function indicates the common functions.

This topic describes typical function definitions of smart metering sockets.

The maximum value of a function definition on Tuya Developer Platform is 2147483647.

Bool: Binary variable true or false such as the function of the switch. Value: Apply to the data that can be linearly adjusted such as adjusting the temperature.

After the functions are defined each function is abstracted into a data point DP. Data transfers and device control are implemented based on DPs. For more information see Product Functions.

Cloud functions Cloud function supports cloud timing and jumping page. For more information see Cloud Functions. Cloud timing: allows you to implement the schedule feature without embedded development.

No rollback function is available. It is recommended that you delete the DP and add it again.
