6. Operating Modes

The smart switch supports three working modes: Self-locking, Interlocking, and Inching. The default mode is self-locking.

• Self-locking Mode: In this mode, each of the four devices can be controlled independently. Turning one device on or off does not affect the state of the others. This is ideal for controlling individual lights or appliances.
• Interlock Mode: When one device is turned on, all other devices are automatically turned off at the same time. This mode is useful for applications where only one output should be active at any given time.
• Inching Mode (Jog Mode): In this mode, when a switch is turned on, it will automatically turn off after a customizable duration (default 1 second, configurable from 2 to 3600 seconds in the app). This is suitable for momentary actions like opening a garage door or activating a motor for a short period.
