Condition Configuration

Rule functions can be configured using one of two methods, each offering a different approach to condition configuration:

JavaScript Logic Builder

If you are comfortable with coding, the JavaScript Logic Builder allows the creation of custom logic using JavaScript syntax.

You can create conditions directly by using device data keys within the run() function and data keys are inserted using the ${{KEY_NAME}} format, where KEY_NAME is the name of the data point you want to include.

Example condition:

function run(){
 
    let tmp = ${{TEMPERATURE}};
    let hmdt = ${{HUMIDITY}};
    let light = ${{LIGHT}};
    let motion = ${{MOTION}};
    let vdd = ${{VDD}};
 
    // Your complex conditions go here
 
    if (tmp > 25 && hmdt > 70) {
        trigger();
    }
}

Visual Condition Builder

The Visual Condition Builder provides quick and straightforward condition creation, using dropdown menus to specify parameters and desired conditions.
