Linus

Security company Yale have partnered with Nest, the company behind the smart-thermostat. Linus is a door lock that can be controlled remotely with a smartphone. Users can check if the door is open, create pass codes for individuals, and track who has been to visit.

Since releasing their smart-thermostat the Google-owned company have released a smoke-alarm and a home security camera, this lock is the next logical step I suppose. We'll be able to control everything with our phones soon enough!
