device.message.detail (Query one alarm message)

device.message.detail: Query one alarm message

What it does

Fetch one message by alarmId. No permission → whole-call DV2011. Returns one push-shaped object (same as Receive alarm messages), not list count / nextAlarmId. msgType equals eventId.

Legacy alarm / deviceStatus payloads differ; see Receive device messages.

Platform fields are not inside capability outputData.
