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.

Sending any value to the Trigger port will execute the script.

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″
