5 Data Reporting Communication Protocol

5.1 Protocol Parsing Instructions

For UDP / TCP / MQTT / HTTP and other push methods, users should provide the public network IP (or domain name) address and port number of the cloud server to receive the data.

Example of JSON format:

{"T":27.8,"PH":67.1,"ID":"860344048491162"}

Message analysis:

{

"T": 32.1, //Temperature

"PH": .6.4, //PH value

"ID": "860344048491162" //Device ID

}

5.2 Protocol Acceptance Test

The network debugging assistant NetAssist can be used for reception testing.

 

5.3 Agreement Customization

If you need to customize other communication protocols, you can contact the business personnel to communicate them.

6 Platform Docking

6.1 Default Platform

The product is connected to our designated industrial Internet of Things platform by default, and the platform interface is as follows:

 

     Computer-side browser interface

Mobile terminal WeChat access interface

6.2 The User Specifies the Platform

Take the connection of Ali Cloud platform as an example. After users create products and add devices on the Ali Cloud Internet of Things platform, users need to provide a triad: {ProductKey, DeviceName, DeviceSecret} and the MQTT theme to be released.

For example, the value of triples is:  

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

Taking the OneNet platform as an example, after a user creates a product or adds a device on the OneNet platform, the user needs to provide the product ID and device registration code.

For example:

ID：332590

Registration code：DGRUa7Vr9KYGunwJ

7 Matters Needing Attention

1）When the device is installed inside the metal distribution box, use an external antenna and print the antenna outside the distribution box.

2）This product has a built-in SIM card, and the annual data fee is about 10~20 yuan according to the reported data frequency. You can also use your own SIM card, which needs to be confirmed in advance.
