TP-Link introduced a $90 smart door lock in China. The device, designated TL-SL31 Lite, can already be ordered in China
The creators emphasize that the lock is fully automatic – no additional actions are required with it after opening or closing the door. So, for example, when the door is closed, the lock is blocked automatically (relatively speaking, the “night latch” is automatically activated). You can unlock the device in five different ways: for example, by using a code on the digital panel, by scanning your fingerprint (response speed – 0.369 s) or from a smartphone. Naturally, the TL-SL31 Lite supports both Wi-Fi and Bluetooth.
A feature of the external design is a digital panel that rotates to the top at an angle of 15 °. The creators assure that the battery life of the lock is at the level of top solutions on the market. Well, in case of discharge, you can recharge the battery through the USB-C port.
