knocki

Knocki is a new smart device that gives you instant control of your favorite functions from any surface. There is no other smart home device like it. Enjoy the freedom to do things more quickly, easily, and naturally, without the hassle of switches, buttons, or smartphones.

Simply attach Knocki to a solid surface. Knocki detects and identifies tap or knock patterns on tables, walls, counters, doors, and more. Using the free app, specify actions that correspond to a certain number or pattern of knocks. For example, you can stick knocki behind your nightstand and then knock your nightstand to turn out lights and set an alarm.
