Here is a nifty gadget that turns any surface smart, allowing you to easily interact with your thermostat, TV, and smart appliances. Knocki is a wireless device, so you can attach it to walls, tables, and doors easily and set custom commands. You will be able to use simple tap gestures to complete tasks.
Knocki can be used to turn your lights on/off, make your phone ring, activate your alarm, control the temperature, and do a whole lot more. It will be compatible with iOS and Android devices. More information is available on Kickstarter.
