Use this Topic to Publish data to more than one variable of a Device with global timestamp

It is possible to send several values with the same timestamp. This is useful to save data upload costs and to create lower rom memory scripts. You can use the global timestamp as follows:

Topic:

/v2.0/devices/{DEVICE_LABEL}
FieldValueRequired
Hostindustrial.api.ubidots.comYes
Port1883/8883 (Non-TLS/TLS)Yes
UsernameYour Ubidots TokenYes
PasswordAny character or leave blankNo
Quality of Service0 or 1No

Payload Structure:

{
  "temperature": 10,
  "humidity": 90,
  "pressure": 78,
  "timestamp": 1634311791000
}
{
  "temperature": {
    "value": 10,
    "timestamp": 1634378596000,
    "context": {
      "status": "cold"
    }
  },
  "humidity": {
    "value": 90,
    "context": {
      "status": "High humidity"
    }
  },
  "pressure": {
    "value": 78,
    "context": {
      "status": "Normal"
    }
  },
  "timestamp": 1634311791000
}

🚧

timestamp hierarchy

If a timestamp is provided within a Dot, it will ignore the global timestamp and use the provided one instead. e.g. the "temperature" variable will receive a 10 with the timestamp: 1634378596000 instead of the global timestamp: 1634311791000.
