Additional equipment

The modular system design enables you to expand the SOMMER door operator with numerous accessories according to the "plug and play" principle. All accessories can be easily assembled, as the slots are color-coded and labeled exactly.

Speichererweiterung von SOMMER
Memory expansion


Serves to expand the memory to 450 hand-held transmitter commands. If service is required, saved data can simply be transferred to a new drive.

Senso from SOMMER


For recording temperature and air humidity in the garage. The carriage automatically opens the door a bit if necessary (e.g. when the air humidity is too high), ensuring perfect circulation. When the optimal value has been achieved, the door is closed, reducing the risk of mould formation.



Additional relay for additional switching of a garage or courtyard light or another 230 V consumer.


Output OC

Transfers the door status (open/closed) to Smart Home systems. Optionally, a further external lighting unit can be operated.



Two functions in one product: The alarm buzzer recognises a break-in attempt and outputs a loud signal tone. The warning buzzer, on the other hand, outputs an acoustic signal during the closing process or when the slip door is open.

HomeLink radio receiver module SOMMER

HomeLink radio receiver module

With the HomeLink radio receiver, the operator can be upgraded to the HomeLink radio control system. The operator can then be controlled with a HomeLink transmitter integrated in the vehicle.

Delta Dore X3D-Modul SOMMER

Delta Dore X3D-Modul

The module Integrates the operator into the Delta Dore Smart Home system. This allows you to control and query the position of the operator via the Tydom app from Delta Dore.
