Homematic IP door lock drive for convenient locking, unlocking and opening of the front door With this door lock drive, door locks can be operated at any time and from any location, enabling smart access control to the respective premises. The door lock drive is installed on the inside of the door and is not visible from the outside. It can be installed on all standard profile cylinders, also with emergency and danger function, which protrude 8 to 15 mm. Access authorisations can be individually configured - depending on the user or time-based, for example to allow a cleaner access via remote control (see accessories) (assignment of personal PINs for app use). Door openings are stored in the Homematic IP app. The door can always be locked during the night, for example, so that there is no need to go out to check. Re-locking after each opening can also be set up (delay time adjustable). In addition, locking and unlocking can be performed individually at any time via app or voice command
