2Adding the Light Switch
This section describes how to add the Light Switch to the system.
STEP 1: Install the Light Switch
Install the device by following the Operating Instructions included in the original packaging.
Note: After installation, the Light Switch will immediately allow the lamp to function. To control
the switch wirelessly, it will need to be added to the free@home network. If the Light Switch has
been assigned to a different SysAP, it will need to be reset. Please see here for instructions.
STEP 2: Open configuration and search for the Light Switch
Ensure that the SysAP is in Access Point mode by pressing the button on the SysAP. The
indicator light will turn solid blue. Connect to the SysAP by selecting it from the list in your
wireless network.
Once connected, open a browser and enter 192.168.2.1 in the address line.
If you have a tablet, use the free@home App.
Note: It is not possible to set up the Light Switch by using a smartphone.
Log in as a user that has configuration rights.

Adding the Light Switch
Product Manual 2CQA 100 001 B0001 │2018-09-28 │5
Start Go to Settings > free@home radio > Search for wireless devices
The SysAP will now search for the Light Switch.
Note: The Light Switch can only be found if the search starts within 30 minutes after the Light
Switch was connected to power. If 30 minutes has elapsed, the user must turn the power OFF
and back ON again to restart the 30 minutes.
The Light Switch will be found automatically and will be inserted into the configuration software.
Please wait until the Light Switch configuration is read. This may take up to 10 minutes.
