Zusammenfassung:	A wireless power transfer system supports wireless power transfer from a power transmitter (101) to a power receiver (105) using an electromagnetic power transfer signal. A power transfer device which is either the power transmitter (101) or the power receiver (105) comprises a power transfer circuit (201) which includes a power transfer coil (103, 107) for receiving or generating the power transfer signal during power transfer. A detector (203) is arranged to detect a change in a power transfer state for the power transfer. A generator (205) generates an event trigger message in response to the detection of the change in the power transfer state and a transmitter (207) transmits the event trigger message to a destination device via a network. The approach may allow a wireless power transfer system to be used to trigger external events.
