Smart door locks on the test: Sesame, open it yourself – please automatically

There is nothing more annoying than standing with the front door fully loaded when you get home, and then having to place your purchases on a damp floor. Smart door locks are designed to solve this and some other problems by opening automatically when you get home.

Over the past few months I have tried three solutions like Nuki, Yale and Teddy, sometimes more and sometimes less exciting. In some cases, smart locks have really made everyday life easier for me. But sometimes when I shake my cell phone in front of a locked door for minutes they make fun of me.

Operating policy is the same for all devices: the locks are connected to the mobile phone via Bluetooth, which can be used to close and unlock from there using the app or open and close automatically when accessing or leaving the mobile phone in your pocket. The so-called bridges, which are provided as ornaments, help to control the locks remotely via the Internet. There are startup gadgets that open the door at the push of a button or after entering the access code.
