How to use triggers with our wireless Art-net controller REACTIVO?

REACTIVO is our small, yet very powerfull Art-net controller. Capable of controling up to 1024 individually addressable diodes, it comes up with a Anroid/iOS app that has many functions. 

For a typical usage in any large or small scale DIY home project, you can use it to control your LED lights. You can switch effects, colors, create a playlist and more. And you can also connect external sensors and set up Triggers that perform certain task. 

Trigger - what it is and how to use it?

REACTIVO has two inputs that you can use to connect your triggers. Digital sensors that you can connect then trigger specific events, e.g. play specific color on your LED strip. 

Among many sensors that you can use are simple buttons or motion sensor. In the current version of the firmware, you can program these actions: 

  • Switch Color 
  • Switch Animation
  • On/Off
  • Play Specific Animation
  • Play Specific Animation for Exact Time
Example of sensors that can be used with REACTIVO

Basic Settings

You can set your triggers in the Web Config of your device. Click on the Menu icon and Select Triggers.

The setup is divided into three main sections, or steps, that you need to set: 

  • Trigger Source
  • Event type and Event Settings – e.g. which animation from SD card should play
  • Advanced Settings for Event – e.g. multi click/push behavior, delay, etc.

There are default Triggers set in the device to switch the animations stored on an SD-Card with simple buttons.

Each trigger Event has more Optional Settings. Optional settings are unique to each event and you can use it to set how the Event will play the animation.

Advanced settings

This is an optional step in the setup and it allows you to set advanced conditions for each event. It also allows you to set parameterst that are otherwise in default values. This section is also important to visit for some types of sensor. For the motion sensor for example. You want to setup only a short animation while the sensor is detecting movement.

The examples of Advanced settings for Events:

  • Press count – how many time to press the button to perform task/event
  • Press delay – pause lenght between the press/push
  • Invert
  • Duration – of the animation 

Current version of the Firmware supports buttons or sensors with simple binary input. It can also work with analog inputs, but only when those are converted to binary values. Once the inputed value is greater then 0-1, it will automatically switch the trigger. 


In the feature we will implement full support fot the analog inputs that will further expand the options for triggers.
