Our homes are increasingly filled with gadgets that connect to the internet in ways that rightly have us concerned for our privacy and security. But when discussing those concerns, it's important to keep a level head and consider just what kind of privacy and security concerns actually stem from using these products, and in what instances they might actually enhance both for you in real, tangible ways. And like surveillance cameras, we think smart locks fall into such a category: they can actually make your home safer and more secure than a traditional, "dumb" lock, and they do it all while bringing a tremendous amount of convenience.
I have tested dozens of smart home products in my time here on Android Police, yet few of them have been as reliable and as effortless to use as Nuki. This smart lock that I reviewed back in December of 2017 has stayed on our door, offering us quick access to our house without any keys. So when the company told me it had a second generation available, I quickly jumped on the opportunity to try it out.
Nuki 2.0 doesn't change a lot, but improves a few features. The lock is still made for Euro Style/Profile Double Cylinders. It is now also compatible with knob and oval cylinders, uses Bluetooth 5.0 for better range, works with Apple HomeKit, has a Zigbee radio (though it's not active yet), and more conveniently, comes with a little sensor that detects when the door is physically open or closed.
