    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.

    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.

    Let me refresh this topic and ask you gentlemen as experts - is there a real danger that all these smart handles, locks based on the Tuya protocol can be easily hacked ?
    I personally have owned a smart door handle for over 4 years, one of the first I think that was available on Ali for my flat in a block of flats. It unlocks on a fingerprint, card, code and unlock request sent to the phone.
    For me, as a disabled person, such a handle is a great thing, because my hands are becoming less and less dexterous and the problem of turning the key would be greater and greater, but I am increasingly wondering if, for example, such a card can be copied? Do I have anything to fear? Are the solutions in smart Yale products etc. really several classes higher in security than in "stupid Tuya" as "experts" claim, or is it just the fact that you pay several times more for a product from a reputable company that creates such a feeling.

Topic summary

✨ A user has acquired a Tuya-based smart door lock featuring fingerprint and face recognition capabilities, along with remote video calls, card access, and password options. They are exploring the possibility of integrating the lock with Home Assistant, similar to their experience with Tuya lights. The lock includes a USB-C port for emergency power during low battery situations. Community members suggest using the TuyaMCUAnalyzer to sniff communications between the module and MCU, although there are concerns about the limitations of OpenBeken regarding facial recognition and fingerprint functionalities. The user plans to create a backup and investigate MCU sniffing further, noting that the app allows temporary password setup and alerts with images.
