Event message format

Event message format examples

Sections 1–3 below are legacy alarm/iot/deviceStatus callback samples (did/cid/desc); msgType enums are in Event message types (legacy table). Capability catalog events (capabilityEvent, deviceId/outputData) are in 4. Capability catalog events and Overview and common payload. Archived copies of sections 1–3: legacy payload format.

1. General alarm messages (legacy push)

Only devices with platForm 4 include a token field on alarm messages.
The desc object holds different fields per message type.

4. Capability catalog events (`capabilityEvent`)

After subscribing to capabilityEvent via setMessageCallback, msgType equals the capability eventId and business fields are in outputData. Index: Event types; push payload: Overview and common payload. Full field tables are on each capability event page (e.g. Algorithm package download result). Setup: Receive device messages · Receive alarm messages.

{
 "msgType": "algorithm.package.downloadResult",
 "deviceId": "TESTIPC000012345",
 "productId": "56WGTET2",
 "outputData": {
 "type": "1",
 "dwnResult": {
 "ret": "1",
 "url": "https://example/pkg.bin"
 }
 },
 "time": 1673406989,
 "localTime": "20230111T111629",
