Device simulator

The device simulator app simulates data input in Eliona.

Overview

This guide provides instructions for 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 the Eliona settings. Below are the general steps and details for configuring the app.

Configuration of the device simulator app

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

Attribute	Description
asset_id	ID of the simulated asset.
attribute	Attribute name of the generated data.
subtype	Subtype of the generated data (e.g. "input").
function_type	Function type 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	Indicates whether the generated value should be an integer or a float (true for integer, false for float).
interval_seconds	Interval in seconds for data generation. (Sampling rate) (How often should new data be generated?)
frequency	Frequency in Hz for wave functions. (How often should the function 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
