In the KNX configurator screen, after adding or learning KNX addresses, select the KNX group address in the centre pane, and press the [color=\"#ff0000\"]Switch Device ON[/color] or [color=\"#ff0000\"]Switch Device Off[/color] buttons (on the right pane) to test the KNX address.
This should switch on or off the KNX device. It is not necessary to WRITE to EEPROM for the UCM/KNX to use the test buttons. See the screenshot below

However, there is a BUG in Comfigurator up to 3.10.4 - The Test buttons do not work for KNX group addresses 1/7/X (where X is the subgroup). This is a problem for the test buttons only, but the actions to send a command to control 1/7/X will work
