To connect your Smart Lock to the Internet, you need the Nuki Bridge. For this, your Bridge needs to receive a Wi-Fi signal with 2.4 GHz.
The Nuki Bridge can generally be used with a power supply of 110 to 240 V. Please note that a socket in the immediate vicinity (<5 m distance) of the Smart Lock should be used to guarantee an optimal connection between the Bridge and the Smart Lock.
