Function Definition

Types of data point (DP)

Tuya IoT Platform allows you to define functions with six data types, including bool, value, enum, fault, string, and RAW.
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.
Enum value: A custom finite set of values, such as the high, medium, and low levels.
Fault: specified for fault report and statistics. Support Only report when multiple faults occur.
Char type: It indicates data transfer in CHAR type.
RAW type: It indicates data transfer in a RAW binary format.

Description of DPs

DP20(1): on/off (required)

Type: Boolean
Value: true/false. Turn on or turn off

White light mode/color light mode/scene/music light

Example: {“21”:“scene”}

Note:
White light, colored light, scene, and music light are displayed at the bottom tab on the mobile app.

• White light: determined by two DPs together, mode and brightness.
• Colored light: determined by two DPs together, mode and color.
• Scene: determined by two DPs together, mode and scene.
• Music light: determined by two DPs together, mode and music.
• Delay time: determined by the DP timer.
• Schedule: determined by the enablement of cloud timing in the advanced cloud functions.

DP22(3): brightness

Type value

• Value: 10 – 1000
• Example: {“22”:670 "}

Note: The brightness range of 10 to 1,000 corresponds to the value range of 1% to 100% on the mobile app. The minimum value is 1%.

DP23(4): color temp

Type value
Value: 0-1000
{“23”:797"}

Note: The color temperature range is from 0 to 1,000. It is defined between the coolest white and warmest white. The actual color temperature depends on the bead specifications, such as 2700K to 6500K.

Custom functions

You can customize functions that are not supported by standard functions. Data point (DP) is the abstract representation of function, and each function can be defined by different function types. Six data types, namely Boolean, Integer, Enum, Fault, Char type, and RAW type.

Custom DP does not support third-party voice and third-party cloud docking. If you have good suggestions for the expansion of our standard DP. It is recommended to submit a ticket. Tuya will help create standard data functions as soon as possible.

DP ID is synonymous with the function, and the function name is used to quickly distinguish the function represented by the function.
The identification name is the unique identity that distinguishes functions in the product software.
You can select the type according to the DPs. The Tuya IoT Platform supports six data types, including Boolean, value, enum, fault, string, and raw.

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. You should set the value range, spacing, and scale value. The scale value can be set to 0, 1, 2, 3 and transmitted in the exponential conversion of 10, suitable for decimals.

Enum: a self-defined limited set of values, you need to set the enumeration value and confirm with Enter. It supports numbers, letters, and underscores, such as high, mid, and low gears;

Fault: specified for fault report and statistics. Support Only report when multiple faults occur.

RAW type: It indicates data transfer in a raw binary format.

The data transmission type is divided into send and report, send only, and report only. Select a type according to product functions and the panel.
Send and report: Command data can be sent to the device, and device data can be reported to the cloud.
Report only: Data can only be reported from the device.
Send only: Data can only be sent from the cloud.

Cloud functions

Cloud function: It supports cloud timing and jumping page.
Timing allows you to implement functions of on/off timer and weekly schedule without embedded hardware development.
Jumping Page: With a link, users can navigate to another page, such as the online store and user guide.
