Device Variables

What is a device variable?

A device variable is a data point or value that is associated with a specific device or sensor. These variables can represent a wide range of parameters such as temperature, humidity, pressure, location, and much more.

  • What is a derived variable?
    • Derived variable:

      • Derived variables are data points that are calculated or derived from other existing device variables for the same device within a workspace.
      • This variable type represent a way to transform or manipulate the raw data collected from sensors and devices. For example- if a device is measuring temperature and humidity, a derived variable could be the dew point, which is a calculated value based on the temperature and humidity readings.

How to create a device variable?

Quick guide to create a new device variable

  • Click on your Workspace Name to enter within your workspace.
  • Go to -> Administration tab on top right corner.
  • From the left side pane, Go to -> Devices.
  • Click on Device ID, and you will be able to access the Device Variables tab
  • Click on New Variable button to create a device variable.
  • Select the variable Type as Actual or Derived as required.
  • Enter a suitable Name/Label for your variable.
  • Enter the Unit for the device variable.
  • Add suitable Description.
  • You can apply transformation formula on actual Variables or derivation formula on derived variables and mention it under Pre Save Transformation Formula or Derivation Formula block as per your variable type selection.
  • Add suitable Decimal Precision & Widget color for your device variable and click on Save button.
