Nuki

Nuki is an Austrian smart-lock company founded in 2014 by brothers Martin and Jürgen Pansy, headquartered at Münzgrabenstraße 92/4 in Graz with around 150 staff. The Nuki Smart Lock retrofits existing euro-cylinder doors and can unlock them automatically in under a second using a brushless motor. The newest generation supports Matter and integrates with Apple Home, Alexa, Google Home and SmartThings; the lock can be used without an account, with end-to-end encryption and local-first data. The lock starts at $159, the Smart Lock + Keypad 2 bundle at $229, and an optional Nuki Premium subscription is $5.90/month.
