Develop Product
Last Updated on : 2024-06-20 03:16:58download
To develop a product on the Tuya Developer Platform, you need to define product functions, select and customize device panels, develop embedded firmware, and perform a production test.
Step 2: Define product functions
You can set functions for a product, including standard functions, custom functions, and cloud functions.
A product function is the abstraction of a feature that is provided by a smart device. You can use product functions to describe the features and parameters of smart devices. Based on the product functions, the Tuya Developer Platform generates things data models in the cloud to connect to and control the smart devices. This makes product functions and data interactions easy to understand.
DP data type
Tuya Developer Platform allows you to define functions with six data types, including Boolean, value, enum, fault, string, and raw. For more information, see Data type.
Standard function
Standard functions indicate the common functions in a specified category to implement standard device interconnection.

| 16 | Cycle irrigation | cycle_time | Send and report (read/write) | string | / | Specify a period to cycle a device between ON and OFF, and set how long you want the ON and OFF state to last in a cycle. This provides a convenient way to automate light routines such as for cyclic irrigation, pet feeding, and control of lighting scenarios. |
| 17 | Normal timer | normal_timer | Send and report (read/write) | string | / | Users can customize the recurring period, irrigation period, and multiple cyclic irrigation tasks. The task can be run weekly, on an even or odd days, or at a specified time every two days. |

|
/ |
| 19 | Temperature and humidity sensor power | temp_hum_battery_percentage | Report only (read-only) | value |
|
/ |
| 20 | Humidity upper limit setting | maxhum_set | Send and report (read/write) | value |
|
/ |
| 21 | Lower humidity setting | minihum_set | Send and report (read/write) | value |
|
/ |
| 22 | Temperature | sensor_temperature | Report only (read-only) | value |
|
/ |
| 23 | Temperature upper limit setting | maxtemp_set | Send and report (read/write) | value |
|
/ |
| 24 | Lower temperature setting | minitemp_set | Send and report (read/write) | value |
|
/ |
| 25 | Sensor setting | switch_enabled | Send and report (read/write) | bool | / | / |
| 26 | Freeze temperature | temp_current | Send and report (read/write) | value |
|
/ |
| 27 | Windspeed | windspeed_avg | Send and report (read/write) | value |
|
/ |
| 28 | No irrigation time | no_irrigation_time | Send and report (read/write) | string | / | Irrigation duration is limited by water valve controllers. Users can set a period in which one-time tasks or cyclic tasks are disabled. After this period, irrigation tasks can be run as expected. This is intended to meet the water usage limits in certain areas. |
Custom function
You can add custom functions that are not supported by standard functions. For more information, see Custom Function.
Cloud function
Cloud functions support cloud timing and jumping page. For more information, see Advanced Function.
- Cloud timing: allows you to implement the schedule feature without embedded development.
- Jumping page: enables navigating to another web page, such as an online store or user guide.
Step 2: Configure a panel
After the function definition step, you can configure a favorite app control panel for the product. A panel is a GUI-based program that runs on top of a mobile app to control smart products. For more information about panel configurations and development tutorials, see Design App UI and Panel Development.
Step 3: Develop software
Hardware development involves hardware design and embedded development. For certain electrical products, the no-code development solution is available. Therefore, you only need to set parameters in a configuration file before firmware can be generated without coding. In addition, you can implement custom development based on the MCU SDK or TuyaOS as needed.

Step 4: Perform embedded programming
Embedded programming is classified into MCU low-code development and TuyaOS development. In this step, you must implement device integration and business programming.
No-code development
In this solution, you can set parameters in a configuration file to generate firmware without coding. For more information, see the instructions on the Tuya Developer Platform.
MCU SDK
MCU low-code development enables products with built-in microcontrollers to connect to the cloud and become connected. Tuya provides one-stop IoT development services including the three essentials for typical IoT products, namely network modules, mobile apps, and cloud services. With Tuya’s MCU SDK, all-in-one mobile apps, and control panels, you can focus on application development simply, connect your product to the Tuya Developer Platform easily, and benefit from the cloud services quickly.
For more information, see MCU Low-Code Development.
Smart water valve controllers can be developed based on multiple protocols, including Zigbee, Wi-Fi and Bluetooth combo. For more information, see:
TuyaOS
Built on top of the RTOS, Linux, and Non-OS, TuyaOS is a distributed and platform-agnostic IoT operating system.
With a standard kernel at the core, TuyaOS is designed to tackle the heterogeneity of platforms, systems, and protocols in order to enable quick and reliable integration, interconnection, and interoperability.
The tiered and plug-and-play architecture design allows you to quickly tailor a solution based on your hardware resources hence reducing the cost of development with high cost performance. The efficient remote procedure call (RPC) mechanism and proprietary data point (DP) protocols make communication across protocols possible and easy.
Specifically, the following types of devices can be connected based on this solution:
Step 5: Configure product
In this step, the following settings are involved: firmware updates, voice capabilities, multilingual settings, device notifications, device pairing, smart scenes, quick toggle settings, product knowledge, and product manuals. Based on these settings, global cloud services are employed to promote the personalized user experience. You can update these settings and make them effective immediately without the need to deliver the devices again.
Particularly, multilingual settings, device pairing, voice capabilities, and smart scenes require precision and localized management based on the target user locations and the specific pairing methods and device features.
For more information, see:
Step 6: Flash firmware and authorize chip
Flash the device with the firmware and Tuya’s license to connect the device to the cloud. Tuya provides multiple firmware flashing and authorization methods for you to connect the following types of devices:
Step 7: Test product
Before your product can be released on the Tuya Developer Platform, you must submit a product test report. To test the product, you can download and run use cases, use Tuya’s Cloud Test app, or subscribe to Tuya Test Service.
Download and run use cases
For certain product categories, you can download use cases from the Tuya Test Service page, run the use cases, and then submit test reports.
Cloud Test
Tuya’s Cloud Test app is provided with multiple test modes for you to accelerate troubleshooting based on functional modules. This enables all-in-one tests for the device status and interaction link.
For more information, see Cloud Test App.
Tuya Test Service
For more information, see Tuya Test Service.
Step 8: Release product
In this step, you can release your project.
