Telemetry

Publish telemetry for one or more downstream devices in a single message. Each device entry is an array of objects — either timestamped value objects, or plain key-value objects if you want the server to assign the receive time.

Client-side timestamp
Server-side timestamp

Provide your own timestamp using the ts and values keys:

{
  "Device A": [
    {"ts": 1483228800000, "values": {"temperature": 42, "humidity": 80}},
    {"ts": 1483228801000, "values": {"temperature": 43, "humidity": 82}}
  ],
  "Device B": [
    {"ts": 1483228800000, "values": {"temperature": 42, "humidity": 80}}
  ]
}

Omit ts to have the server assign the receive time. In this case, do not use the values wrapper — place the telemetry key-value pairs directly inside the object in the array:

{
  "Device A": [
    {"temperature": 42, "humidity": 80}
  ],
  "Device B": [
    {"temperature": 42, "humidity": 80}
  ]
}

Field	Required	Description
`ts`	No	Unix timestamp in milliseconds. If present, the array object must also use the `values` wrapper. If omitted, the server assigns the receive time and the telemetry keys go directly inside the array object.
`values`	No	Key-value map of telemetry fields. Required only when `ts` is present.

Replace GATEWAY_DEVICE_ACCESS_TOKEN in the commands below with the gateway device’s access token.
