5. Setup and Installation
5.1 Wiring Instructions
Ensure power is disconnected before performing any wiring. Refer to the diagrams below for common wiring configurations.
5.1.1 General Wiring Diagram (DC/AC 7-32V Input)
Image: This diagram illustrates connecting the relay module to a DC/AC 7-32V power source and controlling a linear actuator. The module supports both Smart Life/Tuya app control, 2.4G Wi-Fi, 433MHz RF, and voice control via Alexa and Google Assistant.
5.1.2 Automating a DC Motor
To automate a DC motor, connect the motor to the relay outputs as shown. The module's interlock mode can be used for directional control.
Image: Wiring diagram demonstrating how to connect a DC motor to the relay module. The input power for the module is 7-32V. Interlock mode can be configured by pressing the mode switch button.
5.1.3 Wiring for a 3-Wire AC Motor (e.g., Shutter/Curtain)
For controlling 3-wire AC motors, such as those found in electric shutters or curtains, follow this wiring configuration. Ensure the interlock mode is set in the Tuya Smart app.
Image: Wiring diagram for connecting a 3-wire AC motor (like a shutter motor) to the relay module. The input power is DC/AC 7-32V. The neutral wire, shutter open, and shutter close wires are indicated. Interlock mode should be selected and set in the Tuya Smart app.
5.2 App Pairing (Smart Life/Tuya App)
- Download the App: Download and install the "Smart Life" or "Tuya Smart" app from your mobile device's app store (available for iOS and Android).
- Register/Log In: Create an account or log in to your existing account.
- Power On: Connect the relay module to its power supply (DC 7-32V).
- Enter Pairing Mode: Press and hold the "Reset" button on the module until the network indicator LED starts blinking rapidly. This indicates it's in pairing mode.
- Add Device: Open the Smart Life/Tuya app. The app should automatically discover the device via Bluetooth. If not, tap the "+" icon in the top right corner, then select "Add Device" and choose "Auto Scan" or manually select "Switch (Wi-Fi)".
- Connect to Wi-Fi: Follow the in-app instructions to connect the module to your 2.4GHz Wi-Fi network. Enter your Wi-Fi password when prompted.
- Device Renaming: Once successfully added, you can rename the device and each individual channel within the app for easier identification.
Note: Even if the relay module loses Wi-Fi connection after initial setup, you can still control it via Bluetooth using your phone within range.
6. Operating Modes
The Tuya 2-Channel Wireless Relay Module supports various operating modes configurable through the Smart Life/Tuya app:
- Momentary (Inching) Function:
When activated, the relay will turn on for a set duration (default 1 second) and then automatically turn off. This is ideal for applications like garage door openers. The inching time can be adjusted from 1 second to 1 hour within the app.
Image: This diagram illustrates how to modify a remote control for use with the relay module in inching mode, often used for momentary actions like opening a garage door.
- Latching (Self-Locking) Mode:
In this mode, each relay acts as a standard on/off switch. Pressing the button (physical or in-app) toggles the relay's state (on or off). This allows independent control of two connected devices.
- Interlock Mode:
This mode ensures that only one relay can be active at a time. When one relay is turned on, the other is automatically turned off. This is suitable for applications requiring directional control, such as motor control for shutters or gates, preventing simultaneous activation in opposing directions.
6.1 Scheduling and Timers
The app allows you to set up to 8 time schedules for automatic control. You can create single, repeat, or countdown timers to turn devices on or off at specified times. This feature is useful for automating daily routines or security lighting.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not powering on. | Incorrect power supply voltage or loose connection. | Verify the power supply is within AC/DC 7-32V. Check all wiring connections for security. |
| Cannot pair with Smart Life/Tuya app. | Module not in pairing mode; incorrect Wi-Fi password; 5GHz Wi-Fi network; weak Wi-Fi signal. | Ensure the network indicator is blinking rapidly. Confirm your Wi-Fi network is 2.4GHz. Re-enter Wi-Fi password carefully. Move the module closer to your Wi-Fi router. Try resetting the module and re-pairing. |
| Voice control not working. | Skill not enabled; account not linked; device not discovered by Alexa/Google Home. | Ensure the "Smart Life" or "Tuya Smart" skill is enabled and your account is linked in the Alexa/Google Home app. Ask Alexa/Google to discover devices again. Check device names for clarity. |
| Relay not responding to app commands. | No Wi-Fi connection; app issue; module malfunction. | Check Wi-Fi connectivity. Restart the app. Power cycle the relay module. If Bluetooth control works, the issue might be with Wi-Fi. |
