Users can choose the appropriate module according to the product's operating temperature range requirements.

The message type pushed by the cloud through FCM is a hybrid message. This means that the message body contains both Notification Message and Data Message.

You can consider using the Message Subscription feature to detect device status changes and broadcast them to your application. For specific operation methods, please refer to the documentation:Quick Start.

In the Pulsar push rule configuration, dpCode should be configured as the actual attribute code reported by the device rather than the DP mode code. This means that if the product has not switched to DP mode, configuring it as the actual code is feasible. When setting filter rules, using the "in" rule will only push the attributes of the code configured in the "in" rule. When using the "not in" rule, the specified code will be filtered out, and the attributes of that specified code will not be pushed, but the attributes of all other codes will still be pushed. Therefore, by using the "in" and "not in" rules appropriately, you can control whether to receive specific attribute pushes of a product without affecting the reception of attribute pushes from other products.

The WBR3 module supports baud rates of 9600 and 115200, and the specific operation is related to the baud rate setting on the MCU side. The module will lock the baud rate for communication with the MCU based on the baud rate of the query information replied by the MCU. Switching baud rates without power failure may not be successful, as switching baud rates in a connected state can lead to communication failure. For stable communication, it is recommended to use a fixed baud rate setting when connecting. No need to go to the cloud indicates that the use of this module is independent of whether it is connected to the cloud, and the reporting frequency is not affected.

The WBR3D module does not support Bluetooth mesh technology; it is a module that supports Wi-Fi and BLE Bluetooth single-point connection.

1. 1. You can copy a new product PID based on the current product. The new product PID will use the same panel as the original product PID. 2. You can manage your panel in the Developer Platform - App - Panel Development. You can bind this panel to your other product PIDs. After binding, you need to go to the corresponding product development - device interaction - select the bound panel. Note: The function points of the PID bound to this panel need to be consistent with the function points of the original product PID, otherwise it may cause panel component display anomalies or loading failures.

Currently, only character and pass-through function point components in the Studio panel support input box entry. You can use the standard control components of these function points, and clicking will bring up the input box to enter characters.

After the panel is packaged and released, the device panels already shipped under this product will also be updated. If your product has already started selling, for product stability, it is recommended not to update and release the panel arbitrarily. After modifying the panel, you can first package it and add it to the whitelist for testing. If the test is successful, then officially release it.

This feature is currently only supported by the public version panel under some products, such as smart meter products. The Studio panel does not support it. If you want to implement this feature, it is recommended to use the panel applet to develop the panel, create a new function point, enter the panel, and send instructions at regular intervals. After receiving the instructions, the device will continue to report. If no instructions are received within a certain period, the device will stop reporting.

Currently, if you need to disable the automatic low power mode of the WBR3 module, you can try setting the relevant field options in the protocol to 0. For more detailed instructions, please refer to the firmware protocol documentation of the WBR3 module. If you need further assistance, it is recommended to contact the Tuya technical support team.

The pure-blood HarmonyOS system cannot support the Studio panel, resulting in the display of the basic panel. It is recommended that users consider switching to other models of phones to use the APP. In addition, product developers can switch to the public version panel or develop a mini-program panel to adapt to the HarmonyOS system. Currently, there are no plans to adapt the Studio panel to the HarmonyOS system.

1. 1. First, check whether the product function point unit is configured with the corresponding language. If configured, please delete the corresponding unit, then Clear the Tuya app cache and test again; (Note: Product feature unit settings have a higher priority than product language support) 2. If the product function point unit is not set, please confirm whether the corresponding multilingual settings in the product multilingual settings have been operated. If set, please switch the system language of the phone and verify.

Huawei phone's version 5.1 HarmonyOS belongs to the pure HarmonyOS system. Under this system, only some public version panels of the smart life application can be displayed normally, while other panels will be displayed as basic panels. The reason for this situation is that the application has not been fully optimized to support the HarmonyOS system. Solving this problem requires waiting for subsequent optimization and updates of the application to ensure consistency in interface display.

Hello, this entry is displayed on all pages of the studio panel and currently does not support hiding.

If you encounter issues such as no data, display errors, or update delays when using the Studio panel charts, please follow the steps below for troubleshooting and resolution: 1. No Data Handling Check whether the chart data binding configuration is correct. If necessary, delete the relevant function points and rebind them. After publishing changes, please wait about 30 minutes for the system to complete data processing and synchronization. If the statistic type is minux (difference-increment), there will be no data if the reported data is smaller than before. You can report larger data to observe or reset the device to report again. If there is still no data after the above operations, it is recommended to try unbinding the device and reconfiguring the network to ensure the data link is normal. 2. Data Display Error Handling First, confirm whether the statistic type settings such as average, sum, etc. (non-real-time statistics) meet expectations. Observe the actual reported data of the device and wait about 30 minutes to 1 hour for the statistics to complete calculation and update. If the data is still abnormal, please unbind the device and clear the data. And reconfigure the network to restore the data reporting and statistical process. 3. Configuration Update Delay Handling After configuration changes, the system usually takes about 30 minutes to take effect, please be patient. If it still does not take effect after 30 minutes, it is recommended to try unbinding the device and reconfiguring the network to refresh the connection status between the device and the platform. If the above steps still do not resolve the issue, please contact the technical support team for further assistance.

In the second step of product creation: on the device interaction page, click "Reselect Panel," then select "Studio Panel." You can then edit your own personalized panel based on the Studio panel. Once your edited personal panel is successfully published, you can choose to use it.

Drag the log component into the workbench and bind the function point you want to display to it. When your device reports this function point, the time of the report will be recorded in the component. (Numeric function points require a value range; otherwise, multilingual entries will be displayed.).

The Studio Panel currently doesn't support redirecting to a specific panel page based on a function point. It only supports manual redirection. You can add a button or icon to the panel and set it to redirect to a specific panel page.

The module is currently available for purchase and has not been EOL.

This situation is usually caused by the App cache. There are several solutions: 1. You can clear the App cache and rescan to get the latest panel content. 2. You can pull down to refresh multiple times on the device list page to get the latest panel information. 3. If the above operations do not work, you can remove the device, clear the App cache, and reconfigure the network to get the latest panel.

1. 1. By checking the device logs, if the device reports too frequently, it may cause the panel to lag and display abnormally. It is recommended to extend the reporting interval, and multiple function points can use packet reporting. Device log viewing guide:Click to view Packet guide:Click document 2. If it is a single DP reporting method, it is recommended that the reporting interval for each DP data be at least 250 milliseconds, which helps ensure data transmission stability and prevents data from being reported too frequently, causing panel lag.

Mesh networking is not supported.

1. 1. After editing and modifying the panel, click Release in the upper-right corner, enter the content, click Confirm, and wait for the panel to be packaged (this may take a while, so please be patient). 2. Wait for the panel to be packaged If your product has already shipped, we recommend testing it and adding a whitelist for testing. This way, only users on the whitelist will load the modified panel. If your product is still in development, we recommend publishing it so you can edit it later if any issues arise. 3. When publishing, we recommend selecting Release and apply. This will select your edited panel for your product. If you select Release Only, your product will still use the previous panel, and you will need to select it on the platform.

You can use this component in the workbench to bind function points or set jump links for each button. You can refer to the attachment below.

Published panels do not support deletion, only editing. If you choose "Save" instead of "Publish" after editing, the changes will be saved to the draft box. Panels in the draft box can be deleted.

Unable to view. If the current content exceeds the maximum capacity of the visualization panel, it is recommended that you delete some unnecessary content.

1. 1. Drag the chart component into the workbench. 2. Bind the function points that need to be counted to the component. 3. Configure the statistical type for the function points. Currently supported types mainly include "Sum": Type description example: Accumulate the reported data within [1 hour/day/month] to get the [sum] of this [1 hour/day/month] data. "Avg": Type description example: Accumulate the reported data within [1 hour/day/month], and divide by the number of [times] reported to get the [average] of this [1 hour/day/month] data. "Minux": Type description example: Take the maximum value of the reported data within [1 hour/day/month], subtract the maximum of the reported data within [1 hour/day/month] to get the usage data of [1 hour/day/month]. ps: If there is no data for [1 hour/day/month], subtract the previously reported maximum data to get the usage data of [1 hour/day/month].

Not supported.

Hello, we currently do not provide the source code files for the Studio panel. If you need to develop a panel, you can refer tocustom panelsfor development.

Bluetooth function cannot be turned off.

Studio does not support export, please use SDK for custom development.

Hello, after editing and modifying the panel, you need to publish it. After publishing, you need to clear the App cache, pull down to refresh, or re-configure the device to synchronize. If it is still not updated, it is recommended that you check in the workbench whether the modified page is set as the homepage.

The unit must be "s," "min," or "h" in the function point definition for the unit conversion option to appear in the workbench. You can switch between hours, minutes, and seconds. For example, if the unit is set to min, check the hours, minutes, and seconds checkbox, and report 60, the panel will display 1 hour, 0 minutes, and 0 seconds.

First-generation IPEX antenna.

This component's logic is that when the function point unit is 'day', 'h', 'min', 's', or 'ms', it won't display in English. You can modify the function point unit to a different value.

The Studio Panel currently doesn't support automatically issuing query commands. Only some public panels support this. We recommend trying a public panel or developing your own device panel using the panel applet.

In the Studio Panel workbench, you can select the Canvas component (right-click - select Layers - Canvas), then select Image Fill in the Styles - Background component on the right, and upload your background image.

1. 1. Find the alarm component in the component library alarm column on the left side of the workbench. 2. Drag the appropriate alarm component into the workbench. 3. Select the alarm component and bind the function points (fault type, character type, transparent transmission type function points are not supported) to the alarm component in the style on the right. 4. Pack and publish the panel. When the reported data meets the conditions and the APP push/phone/SMS push is enabled, the APP push/phone/SMS push will be triggered. PS: Phone/SMS push requires purchasing services. If not purchased, clicking Yes will redirect you to the purchase service page. After successful purchase, you can click Phone/SMS to set whether to enable phone/SMS push.

Because the logic of character based and transparent function points is more complex. At present, the Studio panel can only display character types in a simple manner, displaying whatever is reported and not displaying according to protocol parsing. Transparent transmission supports control and distribution, but it only has simple operational capabilities and cannot parse the protocol. You can test and verify it in practice.

Hello, the Studio panel is supported and you can upload it on the workbench. Please note that the image size should be ≤ 512Kb.

Hello, the development framework used for the Mini Program Studio and RN Studio panels is different, but users are unaware of the process of building the panel. They both drag and drop components in the workbench to build the panel. Currently, the Mini Program Studio panel is still being updated and iterated, and some features may not be fully improved, such as chart components and jump week programs. We suggest that you use RN Studio first. The Mini Program panel is still being updated and iterated, and more features will be supported in the future.

Hello, the Studio panel currently does not support low-power cache distribution function. We suggest that you enable this advanced feature and use the public version panel.

Hello, it will affect. After the modification, all panels will be updated synchronously. Recommended operation plan: Generate a new PID by copying the parent PID, and operate the Studio panel of the new PID for editing and publishing. After publishing, a new panel will be generated. At this point, modifying and updating the parent PID will not affect the new PID.

Yes. The panel edited through the panel workbench supports multiple releases and edits. After successful publishing, it becomes a personal panel, which is displayed under "My Panel". You can continue to click [Edit] for DIY design.

Wi-Fi and Bluetooth combo technology is a solution that combines both Wi-Fi and Bluetooth wireless communication technologies. It enables simultaneous support for Wi-Fi and Bluetooth communication within the same chip, thereby enhancing the multifunctionality and connectivity of devices. Combo module can be resolved into dual communication protocols. At present, Tuya's main application is Wi-Fi+Bluetooth LE dual-protocol device. It can be interpreted as a communication protocol as a language. All Mandarin-speaking devices can communicate with each other, but it is difficult to communicate with English-speaking devices. Unless there is a device that can speak both Mandarin and English, it is what we call a dual-protocol device (combo device). According to the application requirements on the market, there are currently many devices that can be integrated by a single chip. Protocol IoT solutions mainly include: Zigbee+Bluetooth+Wi-Fi, NB-IoT+Bluetooth LE, Wi-Fi+Bluetooth LE, UWB+Bluetooth, etc. This type of chip that can integrate multiple communication protocols is also called "Comb Chip". For more details, you can refer to the link: https://developer.tuya.com/en/docs/iot/wifibt-dual-mode-module?id=Kaiuygu3bshsa.

No. The Bluetooth part of the Wi-Fi_BLE combo module is a low power Bluetooth, mainly used for data transmission, auxiliary networking, and local control. Bluetooth audio (BT) belongs to classic Bluetooth. They cannot be confused.

Dear user, we are sorry for your inconvenience. The steps to control Wi-Fi and Bluetooth combo devices only via Bluetooth are as follows: Make sure your mobile phone has turned on the Bluetooth switch, you need to use the Bluetooth pairing method to re-configure your device (the mobile phone needs to be connected to Wi-Fi during the pairing process, the cloud needs to verify the device, and only needs to be connected for the first pairing). Power off the router used during network configuration (if you are using a mobile phone hot spot to pairing the device, turn off the mobile phone hotspot), turn off the mobile phone Wi-Fi switch, only turn on the 4G and Bluetooth switches, and then wait for about 3-5 minutes. After about 3-5 minutes, the combo module will automatically switch to the Bluetooth control mode because it disconnects from the WAN. At this time, you will still be able to control the Wi-Fi and Bluetooth combo device through the Bluetooth of your mobile phone. More related reading: In Tuya's Wi-Fi + Bluetooth combo module, is the Bluetooth Bluetooth LE or mesh Bluetooth? What is the distribution mode of dual-mode Wi-Fi + Bluetooth module general integration? How to create a Wi-Fi + Bluetooth combo device? Why can't I find a combo module?

The priorities of device control methods are as follows: LAN control (Wi-Fi) Cloud command Bluetooth local control.

You need to select [Wi-Fi+Bluetooth] as the communication method of the device when creating the product, so that you can select the combo module (Wi-Fi+Bluetooth) in the subsequent development of the product.

Yes. However, you must first pair and activate the device through Wi-Fi.

If a device with a combo module is paired and activated and it is disconnected from WAN and LAN, such as when it is taken outdoors, the combo module then works as a Bluetooth module. In this case, the App can scan and detect the Bluetooth module, and the device is online and can be controlled. However, if you remove the device from the App now, it cannot be paired because no router is available nearby.

This is because the cloud development project pushes messages about all devices connected to the App.

To send a message to a device in the test environment, you must log in to the IoT platform and choose Product Device Device Messaging Test to add a test device, and then switch the coding environment in the SDK to the TEST environment. If the device is removed from the test device list, the online environment is resumed by default, and then the coding environment in the SDK is switched to the PROD environment. A message will not be randomly pushed to an environment.

The title bar of the panel supports device name synchronization. You can refer to the following figure.

Message subscription can only collect the information reported by the device. You can query the log to see the instructions issued by the app and API.

Common data types: device online, device offline, device name modification, device function point name modification, device binding user, device deletion, device event notification. Two background configuration data types: upgrade event, user event (register, remove). Message type：https://developer.tuya.com/en/docs/iot/message-type?id=Kavqerli65a1u.

If there is no consumption for more than two hours, it will be discarded. (The device log is valid for 7 days) The message push has a maximum capacity. If it has not been processed, messages will accumulate, and the old data will be overwritten by the new data. Therefore, it is recommended to process the message push data in a timely manner.

No. The HTTP API is used for device control, and message queues pulsar is used for real-time message receiving.

There are three types of Subscriptions: Exclusive subscription-there can only be one consumer at a time. Shared subscription-can be subscribed by multiple consumers, each consumer receives a part of the message. failover subscription-allows multiple consumers to connect to the same topic, but only one consumer can receive messages. Only when the current consumer fails, other consumers start receiving messages. The Tuya puslar belongs to the third type, and the invalid backup subscription is invalid.

1. 1. Add test equipment in IOT platform 2. Change the environment to test in the SDK of message queue.

The current message subscription will forward the status report of the device. The specific alarm information needs to be based on the actual function point of the device, and the alarm information needs to be filtered out by the developer from the status report data.

It is recommended to do this, and your company will maintain it and reduce MQTT link resources.

Wi-Fi Bluetooth dual-mode products can be defined as an upgraded version of Wi-Fi. Almost all Wi-Fi products can be used in scenarios where Wi-Fi Bluetooth dual-mode products can be applied.

Supported, routers with mixed 5G and 2.4G signals or single 5G or 2.4G router can be networked.

WBR3D module is RTL8720DN chip platform, low-power Wi-Fi+BT module, supports 2.4G&5G mode.

Please check the network condition of the 5G router.

Generally, the cloud will determine that the device is offline when the network is disconnected for 3 to 5 minutes. In this case, the module will switch the control mode by itself.

WBR 1 2 3 is the 8720CF platform without 5G. WBR 1D 2D 3D is the 8720D platform with 5G.

Reflow soldering is supported. There is a recommended furnace temperature curve in the module data manual. You can refer to: https://developer.tuya.com/en/docs/iot/wbr3-module-datasheet?id=K9dujs2k5nriy.

For WBR series modules, Bluetooth and Wi-Fi do not work at the same time. During network distribution, routing information can be transmitted through Bluetooth to assist in network distribution. After connecting to Wi-Fi, if the router signal disappears and the connection fails, it will switch to Bluetooth mode.

Security considerations: The device dev_id issued by the MQTT control topic will verify the permissions with the current user; adding token will strengthen the security level of the control device again; the configuration failure consideration of the MQTT release control: in addition to accessing the password returned by the MQTT link configuration API In addition to the field is valid, the token is also valid;.

Which user [authorization code] accesses the MQTT link configuration API, the [real device] under the user will be pushed to the source_topic returned by the API.

unique_id refers to the terminal id: when the username/password of the link MQTT is the same, and the MQTT is linked in multiple places, this field needs to be unique; that is to say, this value is user-defined. Under a clientid, you can customize 1, 2, 3... just keep it unique.

The maximum size is 10 KB. A release request exceeding 10 KB will be rejected.

Visualized panels cannot save data. If you want to view previously reported data based on data reported by a device, select the chart component to view statistical data.

Plug & Play is a special software capability that is launched for Wi-Fi & Bluetooth combo modules. Plug & Play addresses various issues, such as low pairing success rate, excessively high protocol coupling, and failure of independent pairing or plug-and-play implementation.

1. 1. Good pairing experience: After a Bluetooth connection with the device is established, the Wi-Fi name and password are automatically transmitted to the device, without needing manual pairing. The device can be found upon power-on, and a pop-up notification is displayed. 2. Troubleshooting guide: When pairing fails, the error causes are analyzed, and guidance is provided for users to add devices. The pairing success rate is higher than 95%. 3. Strong adaptation: Network pairing issues in 2.4 GHz and 5 GHz dual-band environments are dramatically reduced. 4. High cost-effectiveness: Pay for one module, and you will obtain both Wi-Fi and Bluetooth LE features. 5. Direct connection control: When the Wi-Fi network does not work, you can enable the Bluetooth function to directly connect to the device in a near distance.

Perform the following operations: 1. Go to Component Library Basic Elements, drag Image to the central layout page, and upload an image to be displayed in Style area on the right side. 2. Select Style Linkage. 3. Configure the style linkage rules. 4. Save the configurations. Preview and test display in corresponding conditions by scanning the QR code.

The explanations are as follows: Sum-Full: For example, add up the data reported in 1 hour to obtain the sum of the data in this hour. Difference-Increment: For example, the maximum value of data reported in 1 hour minus the maximum value of data reported in the previous hour to obtain the consumed data in this hour. Average: For example, add up the data reported in 1 hour and divide the sum by the number of report times to obtain the average value of data in this hour.

The main difference is the range of operating voltage, where NL indicates a wide voltage range. CBU-NL module:Operating voltage: 2.3V-3.6V CBU module:Operating voltage: 3.0V-3.6V For other details, please refer to the module specification.CBU-NL Module Datasheet CBU Module Datasheet.

The CB3L module uses the 7231N chip. Tuya's Matter over Wi-Fi solution is built on the 7231N chip platform. Therefore, the CB series modules, including CB3L, have a solution that supports Matter.
