Facility Control

Currently, I am trying to figure out if it is possible to have the colour of a button change based on feedback from an Arduino node MCU. 

To change the color of a button, you need to set its style. 

Let's assume feedback you get from the Arduino is a string, you can then set the style of your button (e.g. coloredButton) based on the string value to color red like this:

 ogscript.setStyle('coloredButton', 'bg#ff0000');

The following example grid allows you to choose the color you want to assign to the button using a drop down list provided by a local parameter:

<abs contexttype="opengear" id="_top" keepalive="false">
   <meta>
      <params>
         <param access="1" constrainttype="STRING_CHOICE" maxlength="0" name="msgParam" oid="msgParam" type="STRING" value="blue" widget="combo">
            <constraint>green</constraint>
            <constraint>red</constraint>
            <constraint>blue</constraint>
         </param>
      </params>
   </meta>
   <param expand="true" height="78" left="305" oid="msgParam" top="101" width="253">
      <task tasktype="ogscript">var text = params.getValue('msgParam', 0);
      switch (text){
            case 'green':
               ogscript.setStyle('coloredButton', 'bg#009933');
               break;
            case 'red':
               ogscript.setStyle('coloredButton', 'bg#ff0000');
               break;
            case 'blue':
               ogscript.setStyle('coloredButton', 'bg#0099ff');
               break;
         }</task>
   </param>
   <button buttontype="push" height="79" id="coloredButton" left="81" name="Colored Button" top="104" width="148"/>
</abs>
