Prototype a Temperature and Humidity Sensor with Zigbee Module SDK

1. Log in to the Tuya IoT Platform.

2. See Create Products to create a Zigbee temperature and humidity sensor with a custom solution.

   

3. Select functions for the temperature and humidity sensor. In this demo, the selected functions are shown in the following figure.

   

4. Select a device panel. For more information, see Design App UI.

5. In the step of Hardware Development, select the Self-developed Module SDK, and complete the relevant information.

   

6. In the Download Documents area, you can download the SDK.

   

After you extract the SDK, you can find the demo and documentation in the apps folder.

You can refer to the tuya_simple_tmp_hum_sensor demo for the EFR32MG13P732F512 chip in the sensor directory and modify the code to implement sensing functionality.

1. Modify firmwareInfo in the package.json file, including pid, model_id, and manufacture_name. The specific description is as follows:

   • pid is generated when you create a product in Step 1.

     

   • The values for model_id and manufacture_name can be found in the Zigbee Protocol Specification.

     In this demo, fill TS0201 in model_id field and TZ3000 in manufacture_name field.

   • The following figure shows the modified firmwareInfo in the package.json file.

     

2. Modify ioConfig in the package.json file according to circuit parameters. The following figure shows the modified values.

   

3. When you have finished modifying package.json, you can compile the IAR project. The system will automatically apply the modified values to the application code and generate the firmware for production and updates in the exe folder under the build folder.

   

• Test stage

  With the Simplicity Commander provided by Silicon Labs, you can program the production firmware generated in Step 2 to the development board for testing. The authorization is only valid for seven days. The following section describes how to have the firmware authorized permanently.

  

• Production stage

  Go to Tuya Service & Support and submit a technical ticket for assistance. Tuya’s technical staff will help you upload the firmware and apply for an authorization code for programming and authorizing.

  

After you get the authorization code, you can proceed with programming and authorizing. For more information, see Firmware Programming and Authorization. An authorized module can be connected to the Tuya IoT Platform.

Zigbee devices are connected to the network through a Zigbee gateway.

1. Connect the Zigbee gateway to the cloud with the Tuya Smart app.

2. Enable the device to be pending for pairing according to the pairing setting specified in the code. In this demo, you can press and hold the button on the Zigbee SoC master control board (ZS3L) until the indicator flickers fast.

3. Open the Tuya Smart app, select the added gateway, and tap Add subdevice.

   

4. Follow the prompts to operate. When the device is connected to the cloud, you can control the sensor with the Tuya Smart app.

   

You can integrate popular voice assistants into your products. Go to Tuya Value Added Service and click Smart Voice to find more.

After your device is certified, you will see the voice assistant logo on the product information page. See the Quick Guide of Using Amazon Echo to Control Smart Devices to bind the device to the voice assistant platform and enable device control with voices.
