Apartment building door + apartment door

Ringo was installed in the apartment of this building where it was connected to the intercom. Ringo now offers the user to open apartment door and building door via intercom. No permission was required from the building manager as Ringo does not interfere with the intercom system, only with an intercom handle in the user’s apartment.


User can now rent out the apartment via Airbnb. Guests will receive a digital key to open both doors on their own.
