Smart Lock (lemmy.zip)
submitted 3 weeks ago* (last edited 2 weeks ago) by Foni@lemmy.zip to c/homeassistant@lemmy.world
 

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.

I would not want anything that requires a cloud connection to be responsible for securing my house. The security record of these smart locks also isn't great.

The final question you need to ask yourself is how they fail safe? There have been Tesla owners trapped in burning cars. If, god forbid, your house caught fire can you get out of your door secured with a smart lock?

Yes, working through a third-party cloud is not ideal, but I have not seen anything that matches the price/simplicity and is self-hosted.

Regarding security, I don't have it so I can't confirm it 100%, but it's not supposed to override the traditional key or block the handle, so you shouldn't have that problem.

If you're set on these devices, maybe have a look at the open-source projects meant to strip Tuya devices from their Cloud dependencies. There's some aftermarket firmware available for some devices. And we have projects like TuyAPI, Local Tuya, tuya-mqtt... It involves some tinkering, but some of these devices work with new firmware or a fake version of the API. And there might be some information on specific devices in the HomeAssistant forum. With a bit of luck, someone already tried it. I generally don't buy devices unless there's some info in the forum.
