Devices
An overview of devices, where they can be found, and the various types.

Device Types

The following table provides an overview of all the device types that can be found throughout our API.
Device Name
Device Type
Description
​Temperature​
temperature
Sensor that reports temperature in Celsius.
​Proximity​

Structure

A device is either a sensor or a Cloud Connector and has a defined structure in our APIs. They can be fetched either by listing the devices in a project or looking up a single device, both of which will return device(s) with the structure as shown in the snippet below.

Field
Type
Description
name
string
The device resource name. Includes both the identifier of the project the device is currently in and the identifier of the device itself.
type
string
The device type. See the overview below for a full list.
productNumber
string
The device product number. This is the same product number that can be found on the Sensors and Cloud Connectors support pages.
labels
struct
Device labels are user-configurable metadata key-value pairs. DT Studio uses labels with the keys name and description for the display name and description of the device, respectively.
reported
struct
Contains the last Event of each event type received for this device. Which events are included here depends on the device type. See the overview below to learn which event type is included with which device type.
