Flashing OpenBeken on BK7231N CBU Module in WiFi Presence Sensor: Is It Possible?

I bought WiFi Presence sensor. Opening I found out there is a CBU module which is BK7231N. Does anybody tried to flash OpenBeken? Is it tuya cloudcuttered?

Very interesting, can you share Ali link? So it uses UART to communicate with a sensor? This shouldn't be hard to support.

Hello seems there is a directly connected sensor. I haven't checked it, but the board seems clear of other chips. There is also one button at the side of the sensor.

Will you buy it? If I should wait for your work or try to support it myself.

I'd really love if you tried to do some tests on your side already. I have a long queue of things to do, and I still have some gifted devices from users that I need to handle.

I can guide you step by step by testing process. So, I assume you know how to solder, right? Would you be able to solder wires to those RX/TX pads and try to capture the UART communication between WiFi module and the sensor?
Also, to make sure, check with multimeter to which UART port of CBU is this sensor connected?

Or maybe we can find a datasheet for it?
