Knocki makes any surface a smart one

Turn any surface you can tap into a smart home remote.

Moore’s Law claims that the number of transistors on a chip will go up every two years, while the cost of that same chip will halve. This is why everything from your trashcan to your lightbulbs now comes in a “smart” version, yet there’s still the problem of the interface. Who wants to pull out their phone and start an app to see who’s at the door?

Knocki, which is available for a limited time with best-on-the-web pricing, turns any surface you can tap into a smart home controller. All you have to do is place it on or under a surface, such as a table, connect it to your Wi-Fi network using the companion app, and set tap patterns to trigger specific commands.

For example, you could install Knocki on your front door, and configure it so when you knock on the door three times, it flips on the lights. Someone can knock twice to ping your phone so you can know when a specific guest arrives. Each Knocki can be configured with up to ten patterns, so really you’re only limited by what else is on your Wi-Fi network and your imagination.

You won’t need your phone with you, either; it’s only necessary for your initial setup. And since Knocki uses vibration sensors instead of audio, you can use multiple Knockis and voice assistants at the same time.

Knocki is compatible with a huge range of smart home products and services as well, including Philips Hue, Sonos, Wemo, Nest, IFTTT, and more. It’ll even work with just your phone, so, for example, a quick set of raps on the wall will make your phone chime in order to find it, or another set will put in your favorite food order. At $69.99, Knocki makes smartening up any home simple and affordable, saving you 29 percent on the MSRP.
