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.

{
    "name": "projects/<PROJECT_ID>/device/<DEVICE_ID>",
    "type": "<DEVICE_TYPE>",
    "productNumber": "<PRODUCT_NUMBER>",
    "labels": {
        "<KEY>": "<VALUE>",
        ...
    },
    "reported": {
        ...
    }
}

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.

Wireless Sensors Details

Counting Proximity Sensor

Reports the total number of proximity state changes on each heartbeat. The counter does not reset on heartbeats and will keep getting incremented. The presence of an object and the absence of an object are counted individually, and will both increment the counter with 1. A counting proximity sensor also reports normal touch events if touched and held for a few seconds. This allows the sensor to be identified through Touch to Identify.
