Computer browser interface

Mobile WeChat Access Interface

7.2 User specified platform

Taking Alibaba Cloud platform integration as an example, after users create products and add devices on Alibaba Cloud IoT platform, they need to provide a triplet: {ProductKey, DeviceName, DeviceSecret} and the MQTT topic to be published.

For example, the values of a triplet are:

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

Taking OneNet platform integration as an example, after creating products and adding devices on China Mobile's OneNet platform, users need to provide product IDs and device registration codes.

For example:

ID：332590

Registration code: DGRUa7Vr9KYGunwJ
