    Hello everyone!
    It’s been a long time since I posted anything here.

    Today I have bought a new device from lsc/action store it's the LSC Smart Connect power strip model: 3202888 (I think this model is the latest one).
    On elektroda I have seen another post about this device but it seems to be a different version of mine (3202887) and does not have the same pinout.
    White power strip with four sockets and a green LED indicator. Information plate on the LSC Smart Connect power strip.

    Upon inspection the two versions are very similar mine have black relay and the other one have white relays and different pinout to control them.

    After a quick inspection, I found that it uses the CB3S board with the BK7231N chipset. I did a quick firmware dump and flashed the latest available version of the OpenBeken firmware on it!

    WARNING: The wiring in the picture is incorrect—I’ve reversed the 3.3V and ground pins. Ground should be on the right, and power should be on the left.

    Here is the configuration I found for my version of the power strip.

    Hi, do you have an idea to pass this power strip on openbeken by tuya-cloudcutter.

    Thank you
