Knock knock

The device can be attached under tables, inside cupboard doors and on walls, turning any surface into a user interface. The system is designed to enable users to control their smart home devices intuitively and without the need for a range of platforms and controllers.

Each Knocki can be programmed to operate devices such thermostats and lights wirelessly using a series of taps. It can even be used to make a misplaced smartphone ring or alert the owner that someone is knocking at the front door.

‘If you enable a wall with Knocki, you allow anyone, whether they are in a wheelchair, elderly or a child that can’t physically reach a switch, to go to any part of the wall and control it by knocking,’ co-founder Jake Boshernitzan told Digital Trends. ‘And it’s also simpler than having to take a phone out to look through a bunch of apps to find a specific one to control a specific device.’
