Importing datapoint templates in a model
Datapoint templates for a Device model, Asset model, or Location model can be imported directly from predefined datapoint groups.
Note: Only Realtime Datapoints without any computation are available in datapoint groups and can be imported. If you need to add a datapoint template with computation or a scheduled KPI datapoint template you must add them as a custom datapoint template.Importing Datapoint Templates in the Developer Application
To import a datapoint template in the Developer Application,
Access the Developer Application.
Select Asset or Devices or Location in the left pane based on the model to which you want to import the datapoint template. For this illustration, Device is selected.
Click the name of the model you want to add the datapoint template to.For this illustration device model: IAQ sensor is selected.
Click Add Datapoint.

Select Import From Datapoint Group and click Proceed.
Click Add New Datapoint Group. This action is necessary if the datapoint group you need is not already imported. Once imported, it will remain available for all models in the application, unless the datapoint group is removed. This step is not required if you have already imported datapoint groups into the application. Skip to step 9.
Note: If the datapoint group you need is unavailable, or if you require a custom datapoint template for your specific use case, you can create your own datapoint group with the necessary templates and then import them.
Choose Import From Gallery and click Next.
Select the datapoint group you want to import in the left pane, and click Import. For this illustration, Environmental Monitoring datapoint group is selected.
Select the datapoint group (eg., Environmental Monitoring) from which you want to import the datapoint.
Select the datapoint(s) you want to import and click Import. For this illustration, datapoint templates Temperature, Humidity, and CO2 are selected.
The Datapoint template will now be added to your selected model.
