Standard pushes use capabilityEvent and this page’s msgType; some models may also use legacy msg_type—see device.capability.list and message query.
Device-side momentary siren alarm (not manual SirenStart/SirenStop service invoke). Subscribe to capabilityEvent in setMessageCallback. msgType is detection.siren.activated. Channel-level (includes channelId); outputData is often {}. Clear/stop events are other Siren leaves in the capability catalog.
