Device Simulator

The Device Simulator app simulates data input into Eliona.

Overview

This guide provides instructions on configuring, installing and using the Device Simulator app.

Installation

Install the Device Simulator app via the Eliona App Store.

Configuration

The Device Simulator app requires configuration through Eliona’s settings interface. Below are the general steps and details needed to configure the app.

Configure the Device Simulator app

Generators can be created in Eliona under Apps > Device Simulator > Settings which opens the app's Generic Frontend. Here you can use the endpoint /generators with the POST method. Each generator requires the following data:

Attribute	Description
asset_id	ID of the asset being simulated.
attribute	Attribute name of the data being generated.
subtype	Subtype of the data being generated (e.g., "input").
function_type	Type of function for data generation (e.g., "sin_wave", "random", "sawtooth_wave").
min_value	Minimum value for the generated data.
max_value	Maximum value for the generated data.
integer	Specifies if the generated value should be an integer or float. (true for integer, false for float).
interval_seconds	Interval in seconds for data generation. (Sampling rate) (How often should the new data be generated?)
frequency	Frequency in Hz for wave functions. (How often the function should reach the original value per second?) (typically less than 1) (Must not be higher than 1/(2*interval_seconds) to avoid aliasing / Nyquist frequency)

Example generator JSON:

{
  "asset_id": 17202,
  "attribute": "power",
  "subtype": "input",
  "function_type": "sin_wave",
  "min_value": 10.5,
  "max_value": 75.2,
  "integer": false,
  "interval_seconds": 1,
  "frequency": 0.05
