Tuya based Smart Door Lock with fingerprint and Face Recognition

Hi, I have bought a smart door lock from Alibaba with Tuya/3D face/Remote video calls/Fingerprint/Card/Password/Key options. It works pretty well.
I have flashed a lot of Tuya lights to connect them to Home Assistant so I was wondering if it is possible to do the same with the lock.
I am uploading some photos for you to check.
I have one installed and one spare to test and debug, so if someone can point me the right way maybe can dump some data and check how it works.
Thanks in advance.

Do you have pictures with better resolution?

Seems to be WBRU: Link

p.s.
outside unit with usb-c plug? what for?

The usb-c is for emergency power when you are locked out because of low battery.
I am attaching more images.

interesting device. If it's standard TuyaMCU comms then those can be sniffed between module and MCU with https://github.com/openshwprojects/TuyaMCUAnalyzer or the dpIDs can be extracted from Tuya dev after pairing (or I could do this if you grab a WBRU backup)

There isn't provision for setting/configuring facial recognition/finger print/card scanning in OpenBeken so I'm not sure how usable it'll be after conversion ;(

>>21455148 All of those are probably done/stored on mcu, not in the cloud.
App probably can only send command to 'enable' those.
From pics i can see that a password can be set up temporarily, this i can imagine getting sent over tuyamcu protocol. But the rest? I don't know.

Hi, thank you for your input.
I will do my best to make a backup and upload it.
Also will read more about MCU sniffing and how it is done.

The smart app functions are limited I can set temp password for visitors,
I see alerts with images, I can get a video call when someone rings the bell and then I can unlock the door.

The face, fingerprint and NFC card adding is done via key combination on the outside keypad.
