I’m looking for a smart lock for my house and I’ve seen these at a pretty interesting price on Aliexpress (https://a.aliexpress.com/_mMbQRZx), it says that it can be controlled with the tuya app and I have some old plugs integrated from that app, but I also have a lamp that connects to that app but not to the home assistant. Does anyone know if I will have problems integrating this lock into my system? Does anyone have this model or similar?
thanks for the help
EDIT: Thank you all for your responses and help, this is a fantastic community.
I just want to tell you that security is not an issue for me right now, it is much more the combination of price/comfort and not depending on third parties whenever possible.
In any case, I have learned a lot from your answers and I took away important ideas to consider before making a purchase.


Avoid Tuya wifi devices. They’re nothing but trouble, requiring all kinds of hacks to get working locally, and even then can still be a headache.
If you really want the lock, try to see if you can run the Tuya cloud cutter on it, so it’ll be a truly local device. Then control it via HA, using a VPN or HA Cloud if you need remote access.
