Cannot add any matter devices, and thread settings give an error

For zigbee/zwave, it acts as an ordinary zigbee router, like zigbee/zwave lamps and switches do (almost all mains powered zigbee/zwave devices do). And zigbee lamps can go for less than €10,-

This functionality is reserved for 433MHz/Ble/IR.
