To reboot a Locator device:
• Long press on paper-clip button (5-7 seconds)
The RED LED will switch ON for 2 seconds, then the Locator device will actually reboot and switch OFF the RED LED.
Upon reboot, the Locator device will send a "heartbeat" to the backend.
The Locator device will apply the device UI (LED, buzzer) that corresponds to its state.
