    I bought a new garage door opener from a local dealer (Non-US), and it came with tuya
    It has some basic "smart" functions.
    Any information about how it works ?
    If I can use esphome or openbeken with it to get all the functions or at least garage position and open,close and stop buttons
    From what I can tell it doesn't use tuya mcu, just Rx/Tx connections from CB3S module through the USB port.
    The USB plugs directly to the garage motor.

    You can use our GUI tool ( link - https://github.com/openshwprojects/BK7231GUIFlashTool ) to read out the backup from the module via those pads on the back (I would guess), after that we can probably provide some sort of support for your device. DO NOT write anything on the device just backup data and post here.

    Full disclosure - full backup will expose some of your data such is MAC, device serial, wifi ssid and pass etc.
