Create Your Own Smart Lock With A Raspberry Pi, RFID Badge & Custom Code – Review Geek

One of the better smart home products you can buy is the smart lock. It helps you know who is coming and going, and you can set up routines to lock your door at night or when you leave. But it also often means submitting your data to the company that created your smart lock and any connected smart company such as Amazon and Google. If you don̵

7;t like that thought, why not make your own?

Now let’s be transparent and fair in advance: buying a smart lock is easier. If you want something you can just install and use, this is not the route for you. Before tackling this, you’ll want to be familiar with wiring diagrams and coding. You don’t need to write the code, but you will still have to do some work.

But if you’re fairly handy, you should be able to follow YenteDeWael’s directions. At Instructables, he explained the process for making your own smart lock. It doesn’t have a traditional key, which is something to keep in mind too. You unlock the door with an RFID badge, as you see in many office spaces. You can also unlock it with a fingerprint or website access.

Still, not only can you control who comes and goes, but you can also see when the door is unlocked, along with the badge owner. To get started, you’ll need a Raspberry Pi 3 B +, a power supply, a fingerprint sensor, an electronic door lock, and a host of wires. You can find the full list in the Instructables guide.

You also need to build a housing unit to hold and protect everything from the weather and curiosity. The system includes a screen to indicate when your badge is working and a camera to take pictures of the person at the door. All in all, it is a nice (although large and cumbersome) project.

And if all that seems like too much work, then we recommend the Schlage Encode. It works on Wi-Fi, is easy to use and set up, and works extremely well.
