ExoSense® Device Simulator


The ExoSense device simulator tool allows users to create and run devices to use with ExoSense, typically for trying out the application and testing out features, before going through the work to connect a physical piece of hardware.

The ExoSense device simulator is also useful for providing demonstrations and creating repeatable scenarios for testing purposes.


  • Supports up to 10 simulated devices
  • 5 simulators can be running at any time
  • Includes a simple custom waveform simulator type
  • Includes a CSV file reader simulator type
  • Selectable report rate with a minimum setting of 10 seconds supported. Note: If value is set to less than 10 seconds, it will report at 10 seconds.



Simulators are disabled (turned off) after a given set amount of run time - which is specified in the simulators information panel. Users can turn simulators back on if still required for another period of run time.

CSV Reader Simulator Type

This type of simulator loops through data of an uploaded csv file. The CSV file defines the channels, properties, and data. An example is provided for download in the tool.

Getting Started

  1. Click 'Add +' to create a new simulator
  2. Give it a unique identifier and pick a type.
  3. Download the example CSV
  4. Modify or use as is (recommend to try this first)
  5. Upload or drop the CSV onto the simulator CSV link.
  6. Be sure to hit 'SAVE' to apply the new CSV.
  7. Enable the Simulator
  8. Go to 'Unclaimed Devices' in ExoSense and assign to a group
  9. Start using for Asset data


Users can modify the CSV file to add more channels, change the data, and edit properties for the configuration.


  • First row is for the channel identifiers (id)
  • Following rows support adding items from the channel schema interface specification such as:
  • display_name (required)
  • properties.data_type (required)
  • properties.data_unit (required except for NUMBER,STRING,BOOLEAN data types)
  • The last part of the file is for specifying data in rows. Each row is sent in order, at the given report rate.


Recommend the Exosite Industrial IoT Schema documents for more information about the channel configuration

Example in Tabular View

id temperature1 humidity
display_name Temperature 1 Humidity
properties.data_type TEMPERATURE HUMIDITY
properties.data_unit DEG_FAHRENHEIT PERCENT
protocol_config.report_rate 10000 10000
properties.precision 2 2
protocol_config.timeout 30000 30000
properties.locked TRUE TRUE
data 22.43 45.5
23.3 45.67
23.14 45.02
23.02 44.02

example csv file content

display_name,Temperature 1,Humidity


Max CSV file size supported is 100KB

Location data support

Location data can be sent but requires a special formatting in the CSV as latitude and longitude need to be placed inside a JSON formatted value which is not supported in CSV format. The tool will create the JSON data if formatted in this way, note the addition of the 'property' row. This will properly create the JSON value.

Example in Tabular View

id location location temperature1
display_name Location Temperature 1
properties.data_type LOCATION TEMPERATURE
properties.data_unit LAT_LONG DEG_FAHRENHEIT
protocol_config.report_rate 20000 10000
properties.precision 1 2
protocol_config.timeout 60000 30000
properties.locked TRUE TRUE
property lat lng
data 43.67423 -96.18115 22.43
43.67424 -96.18215 23.3
43.67424 -96.18286 23.14

example csv file with location data

display_name,Location,,Temperature 1

Custom Waveform Simulator Type

This type allows for creating channels, setting configuration parameters for the channel, and specifying a waveform such as sine, square, etc. This type has limited functionality but is the easiest to set up and use.

Next Steps

Once the device simulator is running, use the ExoSense guide for creating assets from devices.
