  • 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.

    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

    PinDescriptionNote
    P06Rel 1 (Relay 1)*
    P07Rel 2 (Relay 2)*
    P10LED 1*
    P24Button
    P26LED 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.
    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.
    Helpful post? Buy me a coffee.
