Not every smart plug is supported — it depends on whether ioBroker (or the underlying bridge) has a device handler for it. The list above is limited to smart plugs confirmed to work with ioBroker.
You need a Zigbee coordinator (USB stick) connected to ioBroker. Once the coordinator is set up, you pair the smart plug and it's controllable from ioBroker.
