Because this one smart home product it can stick on any surface, turn all physical surfaces into remote control switches, and through WiFi you can control all smart devices that can be connected. Make everything into a touch screen and tap to control it anytime, anywhere.
A whole wall, desktop or cabinet surface can be turned into a control surface. When you fix Knocki on a wall, nightstand, or table, its internal accelerometer will be able to sense the user's taps on these surfaces, and not only that, but it will also be able to calibrate itself based on environmental data, and be able to realize different functions when it senses different taps, such as turning on the lights in two taps, or turning on the TV in three taps, and so on.
Knocki connects to WiFi, so in theory it could work with most smart devices, such as Nest, Philip's Hue smart light, Spotify, and Wemo, and has an internal battery that can last up to a year. Before using the device, users need to connect the smart device and its companion app (which supports both Android and iOS devices) together.
