    Hello everyone,

    I am making this post because I made a guide on how to flash WB2S tuya board with BK7231T MCU from the new Action SmartPlug.

    # Introduction
    This guide provides instructions for flashing the Action LSC Smart Power Monitoring Plug with the WB2S Tuya board, featuring the [BK7231T MCU](https://developer.tuya.com/en/docs/iot/wb2s-module-datasheet?id=K9ghecl7kc479).

    find the readme here : https://github.com/FlorianSoler/OpenBeken-Act...lsc-smartplug-with-monitoring-guide/tree/main

    ## Requirements:
    * USB to TTL or UART reader
    Flashing Guide for WB2S Tuya Action SmartPlug Power monitoring with BK7231Tusb_ttl_ua...t_back.png (167.21 kB)You must be logged in to download this attachment.
    * Soldering iron
    * Dupont cable or any wire for soldering
    * [OpenBeken flasher software](https://openbekeniot.github.io/webapp/devicesList.html) or any other tool for flashing firmware.

    # Step One

    Begin by opening the smart plug case with a flat screwdriver.

    After opening, you should have access to the board.

    # Step Two

    Locate the Tuya board number on the back of the blue board:
    Flashing Guide for WB2S Tuya Action SmartPlug Power monitoring with BK7231Tboard_nu..r.png (183.54 kB)You must be logged in to download this attachment.
    Google the board name, find Tuya documentation, and confirm the MCU (in this case, the board is a WB2S with [BK7231T MCU](https://developer.tuya.com/en/docs/iot/wb2s-module-datasheet?id=K9ghecl7kc479)). The manufacturer provides all the required data for flashing:

    | Pin No. | Symbol | I/O type | Function |
    |---------|--------|----------|--------------------------------------------------------|
    | 1 | VBAT | P | Power supply pin (3.3 V), connected to VBAT on IC |
    | 2 | PWM2 | I/O | Common GPIO, connected to P8 on IC |
    | 3 | GND | P | Power supply reference ground pin |
    | 4 | PWM1 | I/O | Common GPIO, connected to P7 on IC |
    | 5 | 1RX | I/O | UART1_RXD, used as user-side serial interface, connected to P10 on IC |
    | 6 | PWM0 | I/O | Common GPIO, connected to P6 on IC |
    | 7 | 1TX | I/O | UART1_TXD, used as user-side serial interface, connected to P11 on IC |
    | 8 | AD | AI | ADC pin, connected to P23 on IC |
    | 9 | PWM4 | I/O | Common GPIO, connected to P24 on IC |
    | 10 | CEN | I | Low-level reset, high-level active, Docking IC-CEN (internally pulled high) |
    | 11 | PWM5 | I/O | Common GPIO, connected to P26 on IC |

    # Step Three

    Solder wires on the GROUND, VBAT, RX, and TX pins. Highlighted pinout:

    Thanks for sharing, I always use the same USB to UART converter as you. By the way, can you also share the model number of that Action plug? Futhermore, I also need OBK JSON format template for our devices list: https://openbekeniot.github.io/webapp/devicesList.html You can copy it from Web App main panel. Also fill the "wiki" and "image" URLs

    Hello,
    Thanks for replying. The model is 3202087, the smart plug board number is WP02GE from 2023-09-05. I think this in a new version because they have changed the MCU from the last one.
    For the OBK JSON, I have provided the JSON in the .rar archive, and I have referenced the picture and wiki link from this post.
    Moderated By p.kaczmarek2:


    This is actually 3202088 , as can be seen on the photo. Please do not confuse model numbers

    Hello, the model is 3202088 as seen on the pictures, not 3202087.
    I was just about to submit a new device teardown, not necessary as correct device model will now appear on the search.

    Hello,
    Systematic error from the backup.
    Getting bus failed, will try again - 1/100!
    I checked my 4 solders, reversed TX and RX
    However, the LED lights up as soon as the backup is started.
    My model is the same of this tuto, 3202088
    Thank you for this tutorial.

    well the first step is always to try desoldering WB2S/CB2S. You can check out one of our videos to see how we do it:

    It's not ESP8266, it just waits for reboot to flash.

    I have another idea what could have been wrong.

    There are CB2S/WB2S modules with wrong silkscreen marking.
    You need to follow silkscreen from documentation:
    Diagram of a module with pin designations and dimensions.
    The one on image is correct. The physical module may have swapped (incorrect) markings.

    Futhermore, check out our whole flashing guides list:

    Try different USB to UART converter. There is very, very low chance that the module is defective. I've flashed hundreds of Bekens and none of them were damaged. You can check out many of my teardowns on our Elektroda teardowns list:

    Hello!

    I noticed that several people encountered the same issue as me: "Error Getting bus failed, will try again - 1/100!" when trying to perform a firmware backup.

    Screenshot of the BK7231 Easy UART Flasher application showing an error message.


    To solve the issue on model 3202088:
    "Getting bus failed, will try again - 1/100!"

    You need to solder a second wire to the "GND" pin of your USB to UART adapter. And with this new wire connected to your GND pin, simply touch the CEN pin when performing the backup and also the flashing.

    WB2S module board with labeled pins and description.

    Plug in your USB, set the correct COM port in the application.
    Click on "Do Firmware backup (read only)" to back up the original firmware.
    As soon as the message "Serial port open! Getting bus... (now, please do reboot by CEN or by power off/on)" appears, touch the GND wire to the "CEN" pin, and the backup will proceed.

    Repeat the same process when writing the new firmware.

    Bonjour, j'ai bien flashé mes prises avec tuya cloudcutter, mais pour une j'ai mal renseigné les paramètres ip de ma prise, du coup je la vois sur mon routeur mais je n'arrive plus à accéder à la page des paramètres.
    Y a-t-il un moyen ou une technique pour la réinitialiser ?

    I want to control them without using the Tuya cloud.
    My first test is with a mini smart switch, which has a CB2S controller.
    After taking out the CB2S and connecting it to the USB-TTL converter I could do everything until the first part or step 4.

    Do a 2MB flash read, if you are lucky, the pinout will be extracted and shown on screen. Does it work for you?

    The bin file for flashing (OBK binary) can be downloaded automatically from Easy Flasher

    What your flasher shows now, do you have 2mb backup?

Topic summary

LABEL_AI_GENERATED
Discussion about flashing the Action LSC smart plug with power monitoring, using a Tuya WB2S module based on the BK7231T MCU. The guide covers opening the plug, identifying the board, connecting a USB-to-TTL/UART adapter, backing up firmware, and flashing OpenBeken. Several practical issues are discussed, including incorrect device model identification, WB2S/CB2S silkscreen confusion, backup errors such as “Getting bus failed, will try again - 1/100!”, and the need to desolder the WiFi module or use a CEN pin reset/touch method during backup and flashing. The thread also mentions Cloudcutter as an alternative, macOS flashing options via hid_download_py, device recovery after bad network settings, and confirmation that the flashed plug works with the original pinout and can be reinstalled.
AI summary based on the discussion. May contain errors.
Today's popular

FAQ LABEL_AI_GENERATED

TL;DR: A 2 MB backup is the safest first step, and one expert fix says "touch the GND wire to the CEN pin" if Easy Flasher cannot start on this BK7231T plug. This FAQ helps Action LSC SmartPlug 3202088 owners flash WB2S hardware, import the right JSON, and recover from common backup or access errors. [#21252494]

Why it matters: The thread resolves the exact model number, the correct WB2S/BK7231T workflow, and the main failure mode that stops backup or flashing.

Method Hardware access Main tool mentioned Best use in thread
UART flashing Open plug, solder 4 wires OpenBeken flasher / Easy Flasher Full backup, firmware flash, JSON recovery
Tuya Cloudcutter Avoids disassembly Tuya Cloudcutter Alternative path when users want no teardown
macOS flashing USB connection required hid_download_py Flashing BK7231 devices when the standard tool will not run

Key insight: The most reliable path is still UART with a firmware backup first, then importing the extracted JSON. If backup fails, rebooting the module through CEN at the right moment is the thread’s most concrete fix. [#20975600]

Quick Facts

  • The Wi-Fi module is WB2S with a BK7231T MCU, and the flashing connection uses VBAT, GND, RX, and TX at 3.3 V only. [#20975600]
  • The corrected plug model is 3202088, not 3202087, and the board identifier shared in the thread is WP02GE dated 2023-09-05. [#20976420]
  • The shared OpenBeken pin map assigns 6=Relay, 7=Button, 8=LED, 10=WiFi LED, 11=BL0937SEL, 24=BL0937CF1, and 26=BL0937CF. [#20976420]
  • The extracted configuration includes power-monitoring thresholds of 180 V low-voltage cutoff, 264 V over-voltage cutoff, and a 5 s reset time. [#20975600]
  • Later guidance in the thread says a 2 MB flash read can expose the pinout automatically, which simplifies JSON recovery before reflashing. [#21625232]

How do I flash an Action LSC SmartPlug 3202088 with a WB2S Tuya module and BK7231T using the OpenBeken flasher step by step?

You flash it by opening the plug, wiring the WB2S to a 3.3 V USB-UART adapter, backing up the firmware, and then writing the correct OpenBeken binary. 1. Open the case, identify the WB2S, and solder GND, VBAT, RX, and TX. 2. In OpenBeken flasher, run firmware backup (read only) and save the extracted JSON. 3. Flash the matching BK7231T _UA.bin file, reassemble the plug, join its AP, and import the JSON through Launch Web App → Import → clear OBK and apply new script. [#20975600]

Where can I find the correct pinout and MCU details for the WB2S board before flashing an Action SmartPlug?

You find them on the back of the blue Tuya module and then confirm them in the Tuya datasheet for that board. The guide says to read the module name first, which here is WB2S, then verify that the MCU is BK7231T. The thread also lists the relevant module pins, including VBAT on pin 1, GND on pin 3, UART RX on pin 5, and UART TX on pin 7, which are the key flashing connections. [#20975600]

Why does OpenBeken flasher show "Getting bus failed, will try again - 1/100!" when backing up a WB2S/BK7231T plug, and how can I fix it?

That error appears when the module does not reboot into a state the flasher can catch over UART. The clearest fix in the thread is to add a second GND wire and briefly touch CEN when the flasher shows “Serial port open! Getting bus...” during backup or write. Other thread-tested checks are swapping RX/TX, trying a different USB-UART adapter, and, if needed, removing the module from the main PCB first. [#21252494]

What is the CEN pin on a WB2S module, and how is it used during backup or flashing?

"CEN is a reset input that reboots the BK7231T/WB2S module when pulled low, letting Easy Flasher catch the bootloader during backup or flashing." In this thread, users use CEN as a manual reset point during UART operations. The WB2S pin table identifies CEN as pin 10, describes it as low-level reset, and notes that it is internally pulled high, so touching it to GND briefly triggers reboot. [#20975600]

How do I trigger reboot on a BK7231T/WB2S module by touching GND to CEN during firmware backup or flashing?

You trigger reboot by briefly shorting CEN to GND exactly when the flasher asks for a reboot. 1. Connect a second wire to the USB-UART adapter’s GND. 2. Start Do Firmware backup (read only) or flashing and wait for the message about getting the bus. 3. Touch that GND wire to the module’s CEN pin momentarily. In the thread, this is the specific workaround that solved repeated “Getting bus failed” errors on model 3202088. [#21252494]

What is an OBK JSON template, and where do I paste or import it after flashing OpenBeken?

An OBK JSON template is the device configuration that maps pins and features so OpenBeken knows which GPIO drives the relay, button, LEDs, and power metering. After flashing, connect to the plug’s temporary Wi-Fi AP, open its web interface, then go to Launch Web App → Import and paste the JSON. The guide says to finish with “clear OBK and apply new script,” which loads the saved configuration onto the flashed plug. [#20975600]

How do I get the JSON pin configuration from a 2MB firmware backup in Easy Flasher or OpenBeken flasher?

You get it by reading the original firmware first, because the flasher can extract the pinout from that dump. A later reply states that a 2 MB flash read may automatically show the pin configuration on screen. The original guide uses the same flow: run backup (read only), save the extracted JSON, then reuse it after flashing. If the extraction succeeds, you do not need to build the pin map manually. [#21625232]

Which OpenBeken firmware file should I choose for a BK7231T or CB2S/WB2S device, and what does the _UA.bin file mean?

Choose the firmware that matches the MCU family and use the file ending in _UA.bin. For this Action plug, the guide explicitly says to select the firmware for BK7231T and then flash the _UA.bin image. Later replies add that Easy Flasher can download the OBK binary automatically, which helps first-time users who already completed the backup and JSON extraction. [#20975600]

What’s the difference between model 3202087 and 3202088 for the Action LSC SmartPlug, and why does the correct model number matter?

The thread corrects the device to 3202088, not 3202087, and that matters because device listings, search results, and template matching depend on the exact model. A moderator note says the photos show 3202088, and another reply confirms that 3202087 refers to a different topic. The OpenBeken device entry was then updated so the correct plug appears in the searchable devices list under the right name. [#21030307]

How does Tuya Cloudcutter compare with UART flashing for these LSC/Tuya smart plugs when you want to avoid disassembly?

Tuya Cloudcutter is the thread’s no-disassembly option, while UART flashing is the documented method with backup and pin extraction. A user asked about Cloudcutter specifically to avoid opening the plug, but the step-by-step guide itself uses soldered UART access and a firmware dump first. The thread also shows a real Cloudcutter-related recovery case later, which suggests it works for some users, but the detailed, repeatable instructions here are still the UART method. [#21030267]

Why might a WB2S or CB2S module fail to flash unless it is desoldered from the plug’s main PCB first?

It can fail because the main PCB may interfere with the module’s signals or power conditions during UART access. When one user kept getting bus errors, the first recommendation was to try desoldering the WB2S/CB2S from the circuit and then flash it separately. That advice appears before other checks like different adapters or silkscreen verification, so desoldering is treated as a practical troubleshooting step, not an optional nicety. [#21083703]

How do I recover access to an OpenBeken-flashed smart plug after entering the wrong IP settings and losing the web interface?

You can recover it through the built-in OpenBeken recovery method rather than reflashing from scratch. In the thread, a user lost access after entering the wrong IP settings, could still see the plug on the router, and then restored access using the recovery guidance linked from the OpenBK7231T App FAQ. The follow-up reply confirms the fix worked, so the documented recovery path is the correct first step for misconfigured network settings. [#21451892]

What alternatives are available for flashing BK7231T devices from macOS if the standard flash tool does not run?

Use hid_download_py on macOS. The thread points Mac users to the OpenBekenIOT hid_download_py repository and its README, plus a linked video guide for BK7231N. That reply is the only concrete macOS alternative given, so it is the thread’s recommended fallback when the standard flashing application does not run on Apple systems. [#21131204]

Why do some CB2S/WB2S modules have incorrect silkscreen markings, and how should I verify RX, TX, 3.3V, and GND safely?

Some modules in the field have wrong printed labels, so you should trust the documentation pinout over the silkscreen on the can. The thread warns that certain CB2S/WB2S modules have swapped or incorrect markings and says to follow the documented layout instead. For safe wiring, use only 3.3 V, connect Tuya RX to adapter TX and Tuya TX to adapter RX, and verify GND from the official pin map before powering anything. [#21086520]

Where is the CEN pin on the WiFi PCB of the Action LSC SmartPlug 3202088, and what baud rate should I use for flashing?

The thread identifies CEN from the WB2S documentation, not from a final annotated photo of the 3202088 PCB, and it does not state any baud rate. The WB2S pin table in the guide says CEN is pin 10 and labels it as the reset pin. For the 3202088 board, the practical advice is to locate CEN by matching the module to the official WB2S pinout, especially because some modules may have misleading silkscreen markings. [#21835018]
