Switch Overview

  1. Navigate to HSYCO Manager

  2. Create a new project or open an existing one

  1. Go into the Home page

  1. Click "add"

  1. Add a "Switch" object

  1. Go back to "edit" mode

7. Change the "Name" attribute to "$switchvalue". "$switchvalue" is a variable that will contain the value of this switch (true or false). By doing so, we can directly write the content of this object to a variable and use that variable later with some code

  1. Change the "Label" to "Light ON"

  1. You can enlarge the object by dragging one of the corners and also align it by pressing "Align" and then "Center Vertically"

Tip: Now we'll add the button linked to the dummy datapoint

  1. Click "add"

  1. Add a "Button"

  1. Click "edit"

  1. Move the button at the right of the switch object

  2. Change the "Label" to "Dummy Light 1"

  1. Change the "Action" to "datapoint"

  1. Change the "Datapoint" to "dummy.light.1"

  1. Click "Save"

Tip: Great! Now we'll write some code to flip the status of the light based on the value of the switch. We'll start with the EVENTS code

  1. Go into the File Manager

  1. Navigate into the "events" folder

  1. Click "New File"

  1. Give it a name ("switchevents.txt" for example) and click "New File"

**22. Copy the following code and save the file:

$SWITCHVALUE = true : IO dummy.light.1 = 1
$SWITCHVALUE = false : IO dummy.light.1 = 0

If the switch value is "true", set the dummy light 1 status to 1, which means ON. Otherwise, do the opposite, so set its status to 0 or OFF**

  1. Go back to the Project Editor, click "Run" and then "Default" to launch the application

  1. As you can see, by default the switch is OFF like the dummy light at first

  1. If we press the switch and change its status to "true", the light will turn on

  1. The same applies for the "false" status which makes the light turn OFF

Tip: We can do the same with some JavaScript code

  1. Create a new file under the "events" folder and give it a name ("switchjs.txt" for example)

**28. Copy the following code and save the file:

function varEvent(name, value) : {
    if(name.equalsIgnoreCase("$SWITCHVALUE")){
        if(value.equals("true")){
            ioSet("dummy.light.1", "1");
        }else{
            ioSet("dummy.light.1", "0");
        }
    }
}

What this does is, through the varEvent() function called when a variable cahnges its value, it checks if the name of the variable is "$SWITCHVALUE" (this check is Case Insensitive so even if the variable has a full Upper-Case name, in the equalsIgnoreCase() function you can write its name without worring of upper case or lower case characters) and, if it does, it sets dummy datapoint status to 1 or 0, so ON or OFF**

  1. As you can see, the switch is OFF like the dummy light at first
