After the device is connected to the Internet, third-party client (App) developers of the hardware manufacturer or device buyer can use the OpenAPI or SDK provided by the Tuya open platform for rapid native application (Android / iOS) and web application development (such as : Applets, SaaS backend, cloud platforms, etc.);
For all IoT devices connected to Tuya Cloud, the device control capability is authorized to call through the cloud API. Developers can implement the development of internal business logic by calling APIs. Device status monitoring is opened in the form of message queues to meet The three-party developers’ monitoring of the device status is used to achieve the linkage between different devices.
Tuya Smart Platform has realized the ability of cross-chip platform and cross-communication platform. Tuya Smart supports up to 7 mainstream communication protocols, including Wi-Fi, BLE, BLE mesh, Zigbee, NB-IoT, GPRS, and Sub-G. Wi-Fi supports 2.4G & 5G dual-frequency connection technology;
The Tuya open platform supports the opening of devices of different categories and different communication capabilities to support the application of makers and manufacturers in various home, business and urban scenarios.
The Tuya Open Platform provides various integrate modes based on Tuya’s mature IoT services, combining different docking scenarios:
Simple mode (implicit authorization):
Tuya Cloud provides a cloud-based docking method based on the Oauth2 protocol. Developers can apply for a cloud API on the Tuya iot platform, call Tuya OpenAPI according to the Tuya OpenAPI interface specification, obtain the developer’s own user and device data, and control the device through permissions.
For this case, developers can scan and authorize their “Tuya Smart” APP user accounts on the platform, or need to create OEM applications or create products on the platform. After that, you can get user data or device data based on your development account.
Authorization code mode (explicit authorization):
After applying the cloud API key on Tuya cloud platform, developers can call Tuya open interface based on Tuya OpenAPI interface specification to obtain resource data and authorization scope under authorization Resource data
For cloud integration scenarios where there is no OEM application in the Tuya platform, Tuya cloud provides an authorization code method.
Multi-dimensional data association methods:
Tuya Smart Scan Code Authorization association:
The user downloads and installs the Tuya Smart App, and after binding the device, scans the code and authorizes it to the developer, who has the operation authority over the device under his account.
application association:
The users bound to the device belong to the application created by the developer in Tuya Cloud, and the developer has operation rights for this type of device. For example: using Tuya OEM App or App pairing device based on Tuya App SDK, developers can manage such devices through API;
Product association:
The product belongs to the developer and the developer has a Tuya Cloud IoT account, and the developer has operation rights for this type of device. For example: create a product on Tuya IoT platform and purchase the corresponding module for generation. This type of device is connected to the Internet. You can query the specific device list based on the product id through the API, and perform data subscription monitoring or API control.
Small program SDK association:
The device is based on the small program SDK distribution network, and the small program SDK is associated with the developer’s cloud application, and the developer has operation rights on such devices. For example: Create a small program SDK on the Tuya IoT platform, and connect cloud applications in “Cloud Development”, and use its distribution network equipment.
Authorization code association:
The user grants the corresponding device resource permissions by authorization code to the third-party developer, and the developer indirectly obtains the operation permissions of these devices. Such as: The third-party platform user has an account in the Tuya cloud system (such as an account registered in the Tuya public App). In this case, the user can authorize the device resources owned by Tuya to a third-party application platform. With relevant user rights, it can realize equipment control, management and other functions.
