4. Setup
4.1 Powering the Module
The module can be powered using one of two methods:
- USB 5V: Connect a Micro USB cable to the 5V Micro USB port and a compatible 5V power adapter.
- AC/DC 7-32V: Connect your AC or DC power supply (within the 7-32V range) to the screw terminals labeled 'AC/DC 7-32V'. Ensure correct polarity for DC input.
4.2 App Installation (Tuya Smart Life)
- Download the Tuya Smart or Smart Life app from the Apple App Store (iOS) or Google Play Store (Android).
- Register or log in to your account.
4.3 Wi-Fi Pairing
To connect the module to your Wi-Fi network:
- Ensure your smartphone is connected to a 2.4GHz Wi-Fi network. The module does not support 5GHz Wi-Fi.
- Power on the relay module. The Wi-Fi LED should blink rapidly, indicating it's in pairing mode. If not, press and hold the 'M/S/I Modes Toggle Button' for approximately 5 seconds until the LED blinks rapidly.
- Open the Tuya Smart Life app, tap '+' to add a device.
- Select 'Electrical' > 'Switch (Wi-Fi)' or 'Relay Switch'.
- Follow the on-screen instructions in the app to complete the pairing process. This typically involves confirming the Wi-Fi LED status and entering your Wi-Fi password.
4.4 RF Remote Pairing
The included 433MHz RF remote control can be paired with the module:
- To pair a button on the remote with a specific relay: Press and hold the corresponding manual switch button (1-4) on the module for approximately 3 seconds. The LED on the module will indicate pairing mode. Then, press the desired button on the 433MHz remote. The LED will confirm successful pairing. Repeat for other buttons/relays.
- To clear all paired RF codes: Press and hold any manual switch button on the module for approximately 15 seconds. The LED will indicate that all RF codes have been cleared.
5. Operating Modes
The module supports three distinct operating modes: Inching (Momentary), Self-locking (Toggle), and Interlock. All four channels operate in the same mode; individual channels cannot be set to different modes. You can switch between modes by pressing the 'M/S/I Modes Toggle Button' on the module.
5.1 Inching (Momentary) Mode
Image 5.1: Inching (Momentary) mode application examples.
In Inching mode, when a relay is activated (via app, remote, or manual button), it will remain active for a brief, predetermined duration (e.g., 1 second) and then automatically deactivate. This mode is ideal for applications requiring a short pulse, such as triggering a garage door opener or a momentary switch.
5.2 Self-locking (Toggle) Mode
Image 5.2: Self-locking (Toggle) mode application examples.
In Self-locking mode, each relay acts as a toggle switch. When activated, the relay turns ON and stays ON until it is activated again, at which point it turns OFF. This is suitable for controlling lights, fans, or other devices that need to be switched ON or OFF and remain in that state.
5.3 Interlock Mode
Image 5.3: Interlock mode application examples.
In Interlock mode, only one relay can be active at any given time. When one relay is activated, any other currently active relay will automatically deactivate. This mode is commonly used for controlling motors with forward/reverse functions or other applications where only one output should be active at a time.
5.4 Smart Control Features

7. Troubleshooting
If you encounter issues with your Newgoal Smart Life WiFi 4-Channel Relay Module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not powering on. | No power supply or incorrect voltage. | Check power connections (USB 5V or AC/DC 7-32V). Ensure power source is active. |
| Cannot connect to Wi-Fi. | Incorrect Wi-Fi band (5GHz), wrong password, module too far from router. | Ensure your router is broadcasting a 2.4GHz Wi-Fi network. Verify Wi-Fi password. Move module closer to the router. Reset module to pairing mode. |
| RF remote not working. | Not paired, remote battery low, interference. | Re-pair the RF remote following Section 4.4. Replace the remote control battery. Ensure no strong RF interference sources nearby. |
| Connected device not responding. | Incorrect wiring, relay mode mismatch, device fault. | Verify wiring to the load (NO/COM/NC terminals). Check if the module's operating mode (Inching, Self-locking, Interlock) is appropriate for the device. Test the connected device independently. |
| Relay clicks but device doesn't activate. | Load wiring issue, device power issue, overloaded relay. | Check the wiring between the relay terminals and the device. Ensure the device itself is functional and powered. Confirm the device's current draw does not exceed 10A. |
