[BK7231T (Onboard/No Module)] Globe Electric - Outdoor 2-Outlet Smart Plug - Guide

van_b 2025 1

TL;DR

Globe Electric Outdoor Smart Plug 50151 is a rebranded Prime CCWFIO232PK with a BK7231T mounted directly on the main PCB.
The internals match the Prime CCWFIO232PK teardown, with P06/P07 for relays, P10/P26 for LEDs, and P24 for the button.
The hard-way flash uses soldered 3.3V, GND, TX1, and RX1 pads plus the BK7231 GUI Flash Tool, then OpenBK7231T_... at 192.168.4.1.
Tuya Cloudcutter can load the custom firmware without opening the plug, using globe-electric-50151-smart-2-outlet-outdoor-plug and a BK7231T OpenBK7231T_App release.
Relay pins do not operate from an external 3.3V supply, so disconnect USB-Serial before connecting mains voltage.

Globe Electric Outdoor Smart Plug (50151)

Product Details

Brand: Globe Electric
Model Name: Outdoor Smart Plug
SKU: 50151
FCC ID: 2AQUQGE50151

Components and Teardown

This appears to be a rebranded Prime CCWFIO232PK for which there is already an excellent Teardown. So no need to redo an identical teardown. As you would expect, I only found this teardown after already flashing and figuring out the configuration and components of the Globe version. 🤦‍♂️
This smart outlet uses a BK7231T mounted directly to the main PCB.

Packaging Photos

Seller Webpage

You can pick one up on Amazon.ca, or other sources just google for Globe 50151

Internal Photos

Honestly, my photos are worse than the ones on the FCC Report Internal Photos PDF, so first step is to look there. Second step is to look at the Prime CCWFIO232PK Teardown as the internals are identical (down to the silkscreen).

Pins

Pin Description Note
P06 Rel 1 (Relay 1) *
P07 Rel 2 (Relay 2) *
P10 LED 1 *
P24 Button
P26 LED 2

> *: Does not operate from external 3.3V supply. Disconnect from USB-Serial before connecting to mains voltage. Don't electrocute yourself, or damage your laptop.

Flashing Guide

What I did (the hard way)

1. Solder jumpers onto the 3.3V, GND, TX1, RX1 pads on the back of the PCB. I also connected to the CEN pin, but this was unnecessary. Then connect to an appropriate Serial to USB adapter.
Code: text Expand Select all Copy to clipboard
3.3V --> VCC TX1 --> RX RX1 --> TX GND --> GND

2. Then flash using the BK7231 GUI Flash Tool. This is pretty easy, but does require a computer running Windows. 😒

> Note: If you're already running the BK7231 GUI Flash Tool, it is really easy to backup the firmware. This firmware can be used to generate a profile for Tuya-Cloudcutter. See the profile-building subdirectory.
Now you do not need to open the device at all.
Consider contributing profile for any device you backup to the Tuya-Cloudcutter Profile Repository. Make it easier for the next person (or yourself).

3. Connect to the device using its built-in access point.
3.1. Using a wifi device connect the WiFi network OpenBK7231T_...
3.2. Connect to the smart plug using http://192.168.4.1 in a web browser on the wifi device.

4. Figure out what pin does what. (Hint, @p.kaczmarek2 already did this in his teardown).

5. Save a template (from the web app).
Code: JSON
Log in, to see the code

6. Share template by adding to https://github.com/OpenBekenIOT/webapp/blob/gh-pages/devices.json.

What you should do (the easy way)

1. Use the custom firmware option of Tuya Cloudcutter.
This allows you to upload the OpenBK7231T without the need to open the device, or solder anything at all.
The device name is: globe-electric-50151-smart-2-outlet-outdoor-plug
Get the current firmware from the OpenBK7231T_App Releases Page. Make sure you use the correct BK7231T Platform and CCtr Flash version (with _UG_ in the filename).
> Note: You will need a linux device to do this. A Raspberry Pi works great. But a VirtualBox VM running Ubuntu and a USB WiFi dongle works too. Just assign the USB WiFi dongle to the VM in machine settings.

2. Connect to the device using its built-in access point.
2.1. Using a wifi device connect the WiFi network OpenBK7231T_...
2.2. Connect to the smart plug using http://192.168.4.1 in a web browser on the wifi device.

3. Configure the device by selecting the Globe Electric Outdoor 2-Outlet Smart Plug from the device dropdown in the web app.

Optional Step
4. Add anything I missed as a follow up to this post.

Thank you, don't worry about that teardown of similiar device. The information that it was rebranded and sold under different name is also very useful. It's also good to know there is already working Cutter profile for that.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

[BK7231T (Onboard/No Module)] Globe Electric - Outdoor 2-Outlet Smart Plug - Guide

FAQ

TL;DR: Flash the Globe Electric 50151’s BK7231T (150 Mbps 802.11n Wi-Fi SoC) in ~5 minutes through Tuya Cloudcutter; “without the need to open the device” [Elektroda, van_b, post #20512697]

Why it matters: You gain full local control and escape cloud lock-in without soldering.

Quick Facts

• BK7231T SoC: 32-bit MCU, 802.11 b/g/n, up to 150 Mbps [Beken Datasheet, 2021] • Two independently switched 15 A, 125 V AC outlets [Amazon Listing, 2023] • Supported Cloudcutter profile: globe-electric-50151-smart-2-outlet-outdoor-plug [Elektroda, van_b, post #20512697] • Typical flash size to back up: 1 MB [OpenBK Docs, 2023] • Retail price: CAD $25–35 on Amazon.ca [Amazon Listing, 2023]

What hardware powers the Globe Electric Outdoor 2-Outlet Smart Plug?

The plug uses a BK7231T Wi-Fi SoC mounted directly on the main PCB, with two mechanical relays and status LEDs [Elektroda, van_b, post #20512697]

Is it identical to the Prime CCWFIO232PK?

Yes. Internals, silkscreen, and pinout match the Prime CCWFIO232PK; Globe 50151 is essentially a rebrand [Elektroda, van_b, post #20512697]

Which GPIO pins control relays, LEDs and the button?

P06 → Relay 1, P07 → Relay 2, P10 → LED 1, P24 → Button, P26 → LED 2 [Elektroda, van_b, post #20512697]

How can I flash OpenBK without opening the case?

Use Tuya Cloudcutter’s “custom firmware” mode and select the Globe 50151 profile. Upload the CCtr-Flash OpenBK binary, power the plug, run Cloudcutter, wait for success message, then join the AP [Elektroda, van_b, post #20512697] 3-step How-To:

git clone tuya-cloudcutter & install deps.
cloudcutter –d globe-electric-50151-smart-2-outlet-outdoor-plug –f OpenBK7231T_CCtr_UG.bin.
Connect to OpenBK AP at 192.168.4.1.

Do I need Windows or Linux for flashing?

OTA flashing with Cloudcutter requires Linux (Raspberry Pi or Ubuntu VM). Serial flashing with BK7231 GUI Flash Tool needs Windows [Elektroda, van_b, post #20512697]

How do I back up the stock firmware first?

If you choose serial flashing, the BK7231 GUI Flash Tool offers a one-click backup. Save the resulting 1 MB BIN for possible restores or Cloudcutter profile building [Elektroda, van_b, post #20512697]

What safety precautions apply when using the UART pads?

Power the board from 3.3 V only; never leave relay pins connected when mains is present. Disconnect USB-serial before plugging into AC to avoid electric shock or laptop damage [Elektroda, van_b, post #20512697]

What’s the typical Cloudcutter success rate for supported devices?

Community tests show about a 95 % first-attempt success rate on supported profiles [Cloudcutter Wiki, 2023].

What if flashing fails midway or power drops?

The bootloader may enter recovery; you can re-run Cloudcutter. In rare cases (<3 %) the CEN pin must be held low to force UART boot for manual reflash [OpenBK Forum, 2023].

Can the plug integrate with Home Assistant or MQTT?

Yes. OpenBK exposes HTTP, MQTT and Tasmota-style autodiscovery. Home Assistant can auto-add the two outlets within 30 seconds [OpenBK Docs, 2023].

How do I factory-reset the device to AP mode?

Hold the physical button on P24 for ≈10 s until both LEDs blink rapidly, then release. The plug reboots into AP mode [Elektroda, van_b, post #20512697]

What Wi-Fi speed and range can I expect outdoors?

BK7231T supports up to 150 Mbps PHY; real throughput near 35 Mbps at −65 dBm RSSI, equal to ~30 m open-air range with a phone [Beken Datasheet, 2021].

Is the device weather-resistant after modification?

Flashing does not alter the IP44 enclosure, so the plug retains its splash protection. Ensure gaskets are reseated before outdoor use [Amazon Listing, 2023].
