More and more homes are getting connected as smart homes. And the smart lock is the very first device that controls access to the smart home.
Avnet’s Smart Lock Solution is a powerful solution that boasts a complete set of features. Working with Cloud (RASPBERRY PI 3) and the Android app, it can store a “shadow state” containing access rights, logs and alarms which can be configured while logs and alerts can be viewed. Users can even install and register their locks as well as synchronize updates and policies. As this smart lock works on Bluetooth Low Energy (BLE), it can be unlocked via the Android apps. It can also be unlocked using password via a touch panel, fingerprints, NFC ST25R3911B or using a temporary password created by a smart phone.
