  • the garden light is connected and controlled by an KNX switch actuator
  • the trivum multiroom system is integrated in your KNX installation via KNX/IP router
  • the KNX support of your trivum multiroom system is enabled and ready for use
  • a trivum TouchPad is installed and ready for use

To switch your garden lighting on and off via the trivum TouchPad you have to first create an "switch" button on one of the 8 KNX control screens of your TouchPad. Proceed as follows:

  1. Open the TouchPad WebConfig (How does it work?)
  2. Click on Page Editor
  3. Click on one of the 8 KNX control screens, called "pages"
  4. Move thy mouse coursor over one of the free widget slots
  5. Click on the +-sign, to add an app, button or macro on this free slot
    Tipp: The position of the "switch" button can be adjusted at any time by drag&drop.
  6. Select switch from the list KNX Button hinzufügen

→ The "switch" button has been successfully created and you will automatically enter the configuration page.

The next step is to adjust your "switch" button (color, size, icon etc.) and to parameterized it for your KNX installation. Proceed as follows:

  1. Enter a name for the "switch" button in the field Button Text, for example "Garden"
  2. Click on Icon for 'Off' button and select a appropriate icon from the list, e.g. WallLight
  3. Click on Icon for 'On' button and select a appropriate icon from the list, e.g. WallLightActive
  4. Enter in the text field GA to set on/off (1 Bit) the group address of your KNX switch actuator, which  is parameterized for controlling your garden lighting, for example 5 / 1 /  1
  5. Enter in the text field GA to read status (1 Bit) the group address of your KNX switch actuator, which addresses the feedback channel, for example 5 / 1 / 2

→ The "switch" button has been successfully created and parameterized and you can now control your garden lighting from you trivum TouchPad:
