Tedee Bridge

It connects to your smart lock with Bluetooth and to the internet via Wi-Fi: like a bridge between your device and the global network.
Using a bridge gives you features available only in the online mode: auto-unlock, remote opening, notifications, and auto-updates.
Bridge also enables more opportunities for integrating the smart lock with voice assistants and smart home systems.
You can plug the bridge directly into a power socket or connect it with a micro USB up to 2m away from your smart door lock.
