4. Modalità operative

The module supports three primary working modes, configurable within the eWelink APP:

• Self-locking Mode (Default): In this mode, each channel operates independently. Pressing the button once turns the relay ON, and pressing it again turns it OFF.
• Modalità di avanzamento lento: When activated, the relay will turn ON for a set duration (e.g., 0.5 seconds) after the button is pressed, then automatically turn OFF. This is useful for momentary actions like opening a garage door.
• Modalità di interblocco: In this mode, only one channel can be ON at a time. If one channel is activated, any other active channel will automatically turn OFF. This is suitable for applications where only one operation should occur at a time.
