Scripting Logic Node for Gira X1 and L1

With the SCRIPTING Logic Node you can combine calculations, text processing and custom logic into a single powerful block, replacing multiple formula, formatter and parser modules at once.
Build compact logic flows, reduce wiring complexity and create advanced automations with just a few lines of code. From smart data handling to dynamic text generation and complex conditions: everything runs inside one fast, flexible node.

One block. Endless possibilities.

How it works

Sending any value to the Trigger port (bool/number/text, even false or zero) will execute the script.

Output ports will only change when set in the script. If the script doesn’t set the output port, it will not change, so

if (IN1=5)
  OUT1=1;

will only set the Output port when Input1=5. If you always want to set the value, use

if (IN1=5)
  OUT1=1;
else
  OUT1=0;

Examples

Numbers

OUT1 = IN1 * 1.19;						// Multiply with Mwst.

OUT1 = IN1 + IN2 + IN3 + (IN4+2)		// Set Output sum.

OUT1 = IN1 + IN2; OUT2 = IN1 - IN2;		// Set multiple outputs in one time

OUT1 = (IN1 / 255) * 100;				// Devide and use ( and )

OUT1 = Math.round(IN1 * 100) / 100;		// Math.round will always round on whole number, to have two decimals, device by 100.

OUT1 = Math.min(Math.max(IN1, 0), 100);	// Limit the Input between 0 and 100

OUT1 = Math.abs(IN1);					// Inverse: -5 -> 5

OUT1 = -IN1;							// Also 5 -> -5

OUT1 = Math.pow(IN1, 2);				// (power of 2): IN1²

OUT1 = Math.sqrt(IN1);					// (taking the root): √IN1

Strings (text)

OUT1 = "Hello there!";			// Set a simple text to Output1

OUT1 = "Value is: " + IN1;      // Set combined text+value. Example: "Value is: 10"

OUT1 = "My " + IN1 + " has " + IN2 + " homes";   // Concatenate Strings. Example: "My Son has 2 homes"

OUT1 = IN1.toString().substring(0, 5);    // Take the first 5 characters (start at character 0)

OUT1 = IN1.toString().substring(0, 5);    // Trim spaces

if (IN1.length > 10) OUT1 = IN1.substring(0, 10) + "...";	// Shorten text to 10 characters + "..."
else OUT1 = IN1;

OUT1 = IN1.toString().substring(0, 5);    // Take the first 5 characters (start at character 0)

OUT1 = IN1.replace(/,/g,".");           // Replace all commas by dots.

OUT1 = IN1.slice(-3);  					// Remove last 3 characters

Logic

if (IN1=1) OUT1=1				// Use If to set output ONLY if IN1=1, otherwise do NOT set the output.

var temp = IN1;					// Declare a variable and use it or
OUT1 = tempt;

i=1;
OUT1 = this["IN"+1]				// Computed variabe: OUT1=IN1

if (IN1 >= 50) OUT1 = 1;		// Use if else
else OUT1 = 0;

if (IN1==1) OUT1 = 1;			// Use if, elseif, else
else if (IN2==1) OUT1 = 2;
else if (IN3==1) OUT1 = 3;
else OUT1 = 0;

if (OUT1==1 && IN2==0) OUT2 = 123;	 // Read the value of OUT1 

switch(IN1) {					   // Switch Logic (easier than if/elseif/else)
  case 0: OUT1 = "OFF"; break;
  case 1: OUT1 = "AUTO"; break;
  case 2: OUT1 = "MANUAL"; break;
  default: OUT1 = "UNKNOWN";
}

for (var i = 1; i <= 5; i++) {		// A FOR Loop
  if (this["IN" + i] == true) {		// The computed variable IN1...IN5
    OUT1 = i;
    break;
  }
}

JSON (extra data easily!)

 Sample JSON:
{
  "device": {
    "name": "LivingRoomController",
    "status": "online",
    "metrics": {
      "temperature": 21.6,
      "humidity": 48,
      "power": 312.4
    },
    "modes": [
      { "id": 1, "name": "Auto", "active": true },
      { "id": 2, "name": "Eco", "active": false },
      { "id": 3, "name": "Boost", "active": false }
    ]
  }
}

var obj = JSON.parse(IN1);						// Read Input1 as JSON

OUT1 = obj.device.name;                         // "LivingRoomController"

OUT2 = obj.device.metrics.temperature;          // 21.6

OUT3 = obj.device.modes[0].name;                 // "Auto"

OUT4 = obj.device.modes[2].active;               // false

OUT5 = obj.device.modes.length;                  // 3

OUT6 = obj.device.status + " / " + obj.device.metrics.power + "W";

AI

Examples of asking ChatGPT, CoPilot or DeepSeek for a script:

“Can you generate JavaScript code for the Gira X1 Scripting Logic Module (see examples at https://www.roelbroersma.nl/scripting)?
I have 2 inputs and 1 output.

IN1 = weather information as text
IN2 = expected afternoon temperature (number)

Requirements:

Output format: Temp: XX°C - DESCRIPTION
DESCRIPTION must be truncated to 20 characters and end with .. if longer
Use only plain JavaScript compatible with Jint
Assign the result to OUT1″

Release notes

v0.1.000024 (02-feb-2026)

Fix: Update Notification in GPA (didn’t work!).
Fix: You couldn’t Trigger the block when not all inputs are set, fixed by pre-filling with 0 (zero).
Fix: A lot of small fixes ans possible NullPointerExceptions.
Future: Implemented great Debug logging (enable Debug to see what’s happening).
Future: Debugging shows script execution time. (a hard limit is set at 200ms).

v0.1.000018 (01-feb-2026)

Initial version
Tested on Gira GPA v6.0. X1: v3.0.52 and L1: v2.5.149, but may work on lower versions.
