Frequently asked questions and answers

You can test the functions of the SOMlink service interface in our demo version at www.somlink.sommer.eu free of charge.

The SOMlink is used to adjust safety-relevant settings, which, if not made correctly, may lead to unsafe operation of the door or gate system. Only trained specialist personnel are permitted to use it.

No Internet connection is required to use the SOMlink. All you need is a WiFi-enabled end device such as a smartphone, tablet, laptop or computer.

Standard mode

You connect to the network provided by the SOMlink, which is displayed on your end device in the list of available WiFi connections.

Hotspot mode

Hotspot mode offers a more stable connection between end device and SOMlink. You should use hotspot mode if you have problems connecting in standard mode.

In hotspot mode, the SOMlink connects via smartphone (Android) or PC (Windows) to a mobile hotspot provided by you.

  • The SOMlink must not be supplied with power for longer than 20 seconds when connecting. If necessary, disconnect it and plug it in again.
  • Make sure that the hotspot is spelt correctly in the settings: Name and password (upper and lower case letters, no spaces, correct characters for the Mac address).
  • Update the SOMlink firmware with the help of the SOMMERsuite.

You can change the language on the SOMlink via your web browser. The SOMlink user interface switches automatically to the set browser language.

Use the following link to change the country codes at the end of the URL for the respective national languages: http://somlink.lokal/webglt/index.html?language=de


The network key is saved the first time you log in and therefore does not need to be entered when you connect again.

You can access the user interface via a web browser in standard mode. Unfortunately, for technical reasons, no app is available for iOS. Hotspot mode is not available for iOS devices, as the standard mode functions reliably with iOS devices.

Connection is only possible with iOS Version 13 or newer. Try updating your device to the latest software version. Alternatively, you can test the connection with another browser.

You can find instructions on connecting the SOMlink to an Android device here, in our Download area.

The standard mode is not available via the app on devices with the Android 9 and 10 operating system. When connected with the SOMlink WiFi, standard mode can still be accessed via browser under http://somlink.lokal.

With versions higher than Android 8, we recommend that you use hotspot mode.

Loading can take up to one minute. If it takes longer, please use hotspot mode (Android or Windows devices).

If you cannot load the user interface at all, please check the following:

  • Check that you have entered the password correctly
  • Check the LEDs of the SOMlink. Before connection to the device, both LEDs light up red. If this is not the case, another end device is already connected to the SOMlink. When you connect to the SOMlink, the LED on the right switches from red to green. If necessary, unplug the connected device.
  • Open the user interface via the app or another web browser.
  • Use hotspot mode (Android devices or Windows PC)

Updates with SOMMERsuite

  • The software version installed is displayed on the bottom left of the user interface.
  • The current software version can be accessed via the SOMMERsuite or the Demo version.

The SOMlink is updated via the program SOMMERsuite. You will find instructions and the program here, in our Download area. Make sure that your computer or laptop computer is equipped with an integrated WiFi module or a stick.

If the old software version is still displayed on the user interface after successfully carrying out an update, you should load the page again. Alternatively, restart the browser and delete the temporary data (cache) in the web browser.

The SOMlink is updated via the program SOMMERsuite which is only available for Windows. You will find instructions and the program here, in our Download area.

The SOMMERsuite only runs on a Windows computer or laptop from Windows 7.
