[BK7231T - WB2S] mERKURY WiFi power plug
Hello Community,
I would like to contribute my teardown of a power plug: Merkury MI-WW218-199WW

It uses a WB2S modul, which is based on the BK7231T.
Flashing was done after opening the plug with https://github.com/openshwprojects/OpenBK7231T_App. I used a raspberry pi with a serial adapter. Note: powering the plug needs 3.3 Volt, but the 3.3V output of the Pi is not sufficient. You have to use an external 3.3V power source.
Openning the device is pretty hard but cn be done with acutting around with a strong utility knife. Be carefull as it is easy to demage the pcb (like I did) and then extra soldering is needed.
Some internal pictures:
Settings in the app is pretty straight forward:
P6 Btn 1
P8 LED_n 1
P24 Rel 1
Good luck!

Thank you for presentation, the device will be added to our supported list. Very good note! I am always using my TC1264 for that, buy any simple AMS1117-3.3V will also do well. One can easily get AMS1117,... [Read more]
