Field	Type	Description
deviceId	string	Device identifier
occurredAt	string	Receive time in RFC3339 UTC
rs485.responseHex	string	Raw RS485 hexadecimal data

A response matched to device.rs485.transceive is returned only as command.result.responseHex in the corresponding reply. It is not duplicated as this event. Late responses and unsolicited device data may be delivered through this event.

Events have no history replay. Persist data after receipt when the application cannot tolerate losing it.
