4.1 Working Modes (SMG-8112-SCS)

The SMG-8112-SCS receiver supports three working modes:

• **Inching Mode:** The relay activates for a set duration (2-3600 seconds) after a single trigger, then automatically deactivates. This is ideal for momentary actions like opening a garage door and having it automatically close after a set time.
• **Toggle Mode:** Pressing the button once activates the relay, and pressing it again deactivates it. This acts like a standard on/off switch.
• **Latched Mode:** Pressing one button activates the relay, and pressing a different button deactivates it. This is useful for controlling two separate functions where one action cancels the other.

You can set the Inching mode duration within the Tuya/Smart Life App's timing options.
