3. Setup

3.1 Component Identification

Figure 2: Key components of the relay module, including input terminals, USB 5V input, manual switches, reset button, relay outputs, and network indicator.

• Input DC 7V~32V: Main power input for the module.
• Input USB 5V: Alternative power input via USB.
• Reset Button: Used for resetting the device and initiating pairing mode.
• Manual Switch: Buttons for local control of the relays.
• Relay: Electromechanical switches for controlling connected devices.
• NC (Normally Closed): Relay contact that is closed when the relay is de-energized and open when energized.
• COM (Common): Common terminal for the relay contact.
• NO (Normally Open): Relay contact that is open when the relay is de-energized and closed when energized.
• Network Indicator: LED indicating network status.

3.2 Wiring Instructions

Ensure all power is disconnected before performing any wiring. Incorrect wiring can damage the device or connected appliances.

• Power Supply: Connect the module to a DC/AC 7-32V power source via the input terminals or use a 5V USB power supply.
• Appliance Connection: Connect your appliances to the relay output terminals (NC, COM, NO) based on the desired operating mode.

3.2.1 Interlock Mode Wiring (for Motors/Two-Way Control)

This mode is suitable for controlling devices like motors (e.g., garage doors, window blinds) where only one direction of movement should be active at a time.

Figure 3: Wiring for a three-wire motor in Interlock Mode. The module's outputs control the motor's up/down or forward/reverse functions, ensuring only one is active at a time.

For three-wire motors, connect the motor's control wires to the relay outputs (e.g., one to NO1, one to NO2, and the common to COM). The module will prevent both relays from being active simultaneously.

3.2.2 Self-Lock Mode Wiring (for On/Off Appliances)

This mode is used for standard on/off control of individual appliances, such as lights.

Figure 4: Wiring for AC 220V appliances in Self-Lock Mode. Each relay can independently switch an appliance on or off.

Connect the appliance's power line through the relay's COM and NO terminals. When the relay is activated, the circuit closes, turning the appliance on. When deactivated, the circuit opens, turning it off.

3.3 App Installation and Device Pairing

The module uses the Tuya Smart Life app for configuration and control. Ensure your mobile phone has Bluetooth and location services enabled.

1. Download the "Smart Life" or "Tuya Smart" app from your mobile app store (iOS App Store or Google Play Store).
2. Register or log in to your account.
3. Power on the device. The network indicator should flash quickly. If it does not, press and hold the Reset button until it flashes quickly.
4. Open the Tuya app, tap the "+" icon in the upper right corner to add a device.
5. The app will search for nearby devices via Bluetooth. Tap on the discovered device to add it.
6. Enter your 2.4G WiFi network name and password. Note: 5G WiFi networks are not supported.
7. Wait for the device to connect and be added successfully.
8. Once added, you can rename the device and individual channels within the app.

4. Operating Instructions

4.1 Control Modes

The module supports three primary operating modes, configurable via the Smart Life app:

• Momentary (Inching) Function: When enabled, pressing the switch in the app will turn the relay on for a preset duration (e.g., 1 second to 1 hour) and then automatically turn it off. This is ideal for triggering actions like opening a garage door or gate.
• Self-Locking (On/Off) Mode: Each relay acts as a standard on/off switch. Pressing the button turns it on, and pressing it again turns it off. This is suitable for lights or other appliances requiring continuous power until manually switched off.
• Interlock Mode: Designed for controlling two-way devices (e.g., motors). When one relay is activated, the other is automatically deactivated, preventing simultaneous operation and potential damage.

4.2 App Control

Once paired, you can control the module and its connected devices from anywhere with an internet connection using the Smart Life/Tuya app.

• Remote On/Off: Toggle connected devices on or off directly from the app.
• Timing Schedules: Set up to 8 single, repeat, or countdown timers to automatically turn devices on or off at specified times.
• Device Sharing: Share control of the module with family members through the app.
• Real-time Status: View the current status of connected devices within the app.

4.3 Voice Control

The module is compatible with Alexa and Google Home. Link your Smart Life/Tuya account to your voice assistant app to enable voice commands.

• For Alexa: "Alexa, turn on the light." or "Alexa, turn on Garage door."
• For Google Home: "Hey Google, turn off the bedroom light."
