Trigger

The Trigger node detects when values change in a specific way, rather than checking if they match an exact number (which is what the Compare node does).

Examples:

• Detect when a temperature increases by more than 10 degrees (even if you don't know the exact starting temperature)
• Trigger when a sensor value suddenly drops
• Activate something when a value crosses a threshold going up or down

Real-world example: When the temperature of a room increases above a certain threshold, you can trigger an event to turn on the air conditioning. The Trigger node watches for the change, not just checking if it's above a fixed number.
