Pairing Plug-In

You can integrate the device pairing feature into your WeChat mini program as a plug-in without additional development. You can also configure a group of theme colors with this plug-in. You only need to pass in parameters to integrate device pairing into your WeChat mini program.

Pairing methods

Currently, the pairing plug-in supports Bluetooth 2.0 and later, hotspot pairing (access point or AP pairing) with Wi-Fi devices that blink slowly, pairing with QR code, and wireless pairing with Zigbee devices.

Overview of pairing:

• By default, start pairing by auto discovery. The following types of devices are supported: Bluetooth Low Energy (LE) devices, beacon devices, Zigbee wireless gateways and sub-devices, and combo devices.
• Manual pairing supports Wi-Fi hotspot or AP pairing and IP camera (IPC) pairing with QR code.
• Tap the Scan icon in the top right corner of the WeChat mini program to start pairing with QR code. Narrowband Internet of Things (NB-IoT) devices are supported.

Integrate with pairing plug-in

Step 1: Create WeChat Mini Program Project

Follow the instructions in Plug-In to create an IoT WeChat mini program and request permissions to use the Pairing plug-in.

Step 2: Configure plug-in

Add plug-in settings to app.json of your project.

    plugins: {
      'tuya-ap-plugin': {
        version: '4.4.4', // The firmware version. The latest one is recommended.
        provider: 'wxd2aa51ffacc3ff86', // The appid of the plug-in. No need to modify the value.
      },
    },

Step 3: Access the plug-in

Add the JavaScript code block for navigation to the plug-in:

• Hotspot pairing: The plug-in page guides users to finish pairing through four steps.

  wx.navigateTo({
      url: `plugin://tuya-ap-plugin/step1?clientId=${clientId}&gid=${homeId}&ticket=${ticket}&self_env=inner`,
  });
  

• Pairing with QR code: Open the plug-in page and scan a QR code to start pairing.

  wx.navigateTo({
      url: `plugin://tuya-ap-plugin/virtual?clientId=${clientId}&ticket=${ticket}&gid=${homeId}&self_env=inner`,
  });
  

• Pairing by auto discovery: Open the plug-in page and start pairing with Bluetooth devices, Zigbee gateways, and respective sub-devices.

  wx.navigateTo({
      url: `plugin://tuya-ap-plugin/auto?clientId=${clientId}&ticket=${ticket}&gid=${homeId}&self_env=inner`,
  });
  

  The navigation path includes the following parameters:

  Parameter name	Type	Required	Pairing method	Description
  clientId	String	Yes	Hotspot pairing, pairing with QR code, and pairing by auto discovery	The third-party unique identifier. It matches the value of AccessID for the WeChat Mini Program SDK on the Tuya Developer Platform.
  ticket	String	Yes	Hotspot pairing, pairing with QR code, and pairing by auto discovery	The pairing token. For more information about how to get the token, see User Management.
  gid	String	Yes	Pairing with QR code and by auto discovery	The home ID. A device must be bound with a home. For more information about how to get the home ID, see Home Management (currently in Chinese only).
  duration	String	No	Pairing with QR code	The maximum testing duration for pairing. Unit: ms. Default value: 6000.
  uiMode	String	No	Hotspot pairing and pairing by auto discovery	Configure theme colors
  wifiName	String	No	Hotspot pairing	If the Wi-Fi name is modified in hotspot pairing mode, pass in the new Wi-Fi name in this parameter. Default value: SmartLife.
  wifiRecommed	String	No	Hotspot pairing	To customize a pairing instruction, pass in the URL of the instruction image. Otherwise, use the default image (image size: 303 pixels in width and 228 pixels in height).
  textArray	JSON.stringify(Array)	No	Hotspot pairing	The description of the pairing instruction. Example: [1. Power off the device, wait for 10 seconds, and then power on the device again. 2. Find the Reset button and press and hold it until the indicator starts to blink slowly. 3. Check whether the list of Wi-Fi networks includes a Wi-Fi name starting with SmartLife.]

Step 4: Get device information after successful pairing

Hotspot pairing getNetworkConnect()

Example

const plugin = requirePlugin(‘tuya-ap-plugin’)
const res = plugin.getNetworkConnect()

Return parameters

Pairing with QR code getVirtualConnect()

Example

const plugin = requirePlugin(‘tuya-ap-plugin’)
const res = plugin.getVirtualConnect()

Return parameters

Configure theme colors

The plug-in supports 13 built-in theme colors. You can set the parameter uiMode to switch between theme colors. Default value: orange.
