[OpenBeken Project for BK7231T/WB2S] Flashing Globe Smart Plugs with OpenBeken and Pin Setup

I recently found the OpenBeken project after buying a three pack of Globe smart plugs and realizing they use BK7231T's and not esp8266's. Flashing the plugs with OpenBeken is easy enough given its similarity to Tasmota.



I used a pocket knife to pry open the case. Sliding the edge into the seam between the two halves helped break the adhesive hold.



I soldered on just the 3.3V, GND, RX, and TX wires initially but couldn't get uartprogram to connect. I had to add a wire to the CEN pin as well and short it to GND while the uartprogram was "Getting Bus."



After that, a bit of trial and error led me to the following pin configuration:

P7 - LED_n
P24 - Rel
P26 - Btn

Thank you, device will be added to our templates list. It's interesting to see that your one had WB2S without a metal shield on BK7231T, most of the modules have the metal shield in place.

Any BK flasher requires a reboot during "Getting bus" to work. You can reboot by shorting CEN to GND or by doing a power off/on cycle.

I have the same globe electric smart plug, can I flash it with open beken without opening the plug or soldering?

I have the same globe electric smart plug, can I flash it with open beken without opening it and soldering? I want to take it out of the cloud and use it with home assistant. Right now I am using local tuya within home assistant and blocked internet access for these smart plugs using firewall.

@sandhurajwant61 there is a cloudcutter project, you need to check their page, but it will work only if someone already did a flash dump of this device...

can you please help? I cannot find device profile for my globe electric smart plug

There isn't much that I can do. You can try checking profiles of similar devices and just testing if they work. Maybe you will get one matching. If not, you will need to read flash 2MB by wires with UART and then submit it so they can create new profile for your device.
