The STANDARD MOTOR INTERFACE is the standardised interface for electric drives in roller shutter and sun protection systems. SMI was developed for intelligent drives with integrated electronic circuits. This allows standardised data telegrams to be exchanged from the control to the drive and vice versa. Thanks to SMI, products of different manufacturers can be combined with one another. It is a substantial advantage for architects, planners, roller shutter and sun protection manufacturers as well as controller producers. Drives with an SMI interface offer additional benefits for the user.


Applications to roller shutters and sun protection systems make high demands for robustness and economy. The SMI interface fulfils these requirements.

-       Providing planning reliability

-       Saving energy

-       Uniform design of façade image

-       Optimising daylight

-       Simplifying maintenance
