The Nuki Opener transforms your intercom system into a smart access solution. When combined with the Nuki Smart Lock, you can experience completely keyless entry from your front door to your apartment door. The Nuki Opener is easy to install yourself and allows you to conveniently open the front door remotely when paired with the Nuki Bridge. You can also set a defined time window during which the front door will automatically open when someone rings the bell. This way, delivery services can easily leave your package right in front of your apartment door. The Nuki Opener provides keyless access to multi-family homes and allows for simple self-installation on your existing intercom system. Use the Nuki Bridge for a stable connection from your apartment to the entrance door. Adjustable time windows enable the Nuki Opener to automatically open the door when the bell rings, providing barrier-free access for delivery services to simply drop off your package in front of your apartment door. Access is completely keyless, from the street to your apartment, in conjunction with the Nuki Smart Lock.
