6. Setup
6.1 Wiring the Smart Switch
The smart switch offers flexible power input and passive output connections. Ensure power is disconnected before wiring.
- Power Input: Connect power to the VIN and GND terminals. The module supports DC 5V (via USB Type-C port), DC 7V~48V, or AC 7~32V.
- Output Connections: The relay provides dry contact outputs: Normally Open (NO), Common (COM), and Normally Closed (NC). Connect your device's control wires to these terminals based on your application's requirements.

7. Operating Modes
The smart switch supports two primary operating modes: Inching (Momentary) and Toggle (Latching). You can configure these modes within the Tuya/Smart Life app.
- Inching Mode: In this mode, the relay will activate for a set duration (e.g., 0.5 seconds) and then automatically turn off. This is ideal for applications like garage door openers or electric locks that require a momentary pulse.
- Toggle Mode: In this mode, the relay will switch its state (ON to OFF, or OFF to ON) with each command. This is suitable for controlling lights or other devices that require a continuous ON/OFF state.

Figure 7.1: Configure the operating mode (inching or toggle) within the device settings in the app.
8. APP Control Functions
Beyond basic ON/OFF control, the Tuya/Smart Life app offers advanced functionalities to enhance your smart home experience:
- Timing: Set a specific time for the switch to turn ON or OFF once.
- Schedule: Create recurring schedules for the switch to operate automatically on specific days and times.
- Countdown: Set a countdown timer for the switch to turn ON or OFF after a specified duration.
- Scene Automation: Integrate the smart switch into smart scenes with other Tuya-compatible devices (e.g., turn on lights when a motion sensor is triggered).
- Device Sharing: Share control of the smart switch with family members, allowing multiple users to manage the device.
