Switch in *.item file does not switch KNX actuator

No? You are using openHAB2.5.2.1, by default this version will use knx2, not knx1.

If you are using knx1, then for the fast solution, uninstall knx2, enable legacy bindings (Paper UI->Configurations->System->Add On Management -> Include Legacy 1.x Bindings), then install knx1.

For the long run, please consider to change configuration to knx2, which is using a Bridge (holds config part from old knx.cfg), at least one knx generic thing (better to use one thing per knx device) and per channel one channel. Then link these channels to the items.

EDIT: too slow… :slight_smile:

Another EDIT: As you are using knx1, the logging will be org.openhab.binding.knx1 instead. :slight_smile:
