5. Product Overview
6. Setup
6.1 Powering the Device
The relay module can be powered in two ways:
- USB 5V: Connect a standard Micro USB cable to the 'Power Input 1' port.
- AC/DC 7-32V: Connect a power source within this voltage range to the 'Power Input 2' screw terminals.
Note: The power supply input is for the PCBA (circuit board) only. The relays themselves are switches without output; they control the power to your connected devices.
6.2 Wiring Connected Devices
Refer to the wiring diagrams in Section 9 for specific connection instructions based on your desired operating mode and device type. Each relay has Normally Open (NO), Common (COM), and Normally Closed (NC) terminals. Connect your appliance's power line through the appropriate relay terminals.
6.3 App Installation and Device Pairing (Tuya Smart Life)
- Download the Tuya Smart or Smart Life app from the App Store (iOS) or Google Play Store (Android).
- Register or log in to your account.
- Ensure your smartphone is connected to a 2.4GHz Wi-Fi network. The device does not support 5GHz Wi-Fi.
- Power on the Newgoal relay module. The WiFi LED should blink, indicating it's in pairing mode. If not, press and hold the central button on the module for 5 seconds until the LED blinks rapidly.
- In the app, tap '+' to add a device. The app should automatically discover the device nearby. Follow the on-screen instructions to connect the device to your Wi-Fi network.
- Once connected, you can rename the device and individual channels within the app.
6.4 RF Remote Control Pairing
To pair the 433MHz RF remote control with the relay module:
- Press and hold one of the manual switch buttons (RF Pairing Button) on the relay module for 3 seconds. The corresponding LED will illuminate.
- While the LED is lit, press the desired button on your 433MHz remote control. The LED on the module will flash to confirm successful pairing.
- Repeat this process for each channel you wish to control with the remote. The module can learn up to 14 different 433MHz codes per channel.
To clear all paired RF codes for a specific channel, press and hold the corresponding manual switch button for 15 seconds until the LED flashes rapidly and then turns off.
7. Operating Modes
The Newgoal 4-Channel Smart Wireless Relay Switch supports three operating modes, which can be configured via the Tuya Smart Life app:
- Momentary (Inching) Mode: In this mode, the relay turns on for a set duration (e.g., 1 second) and then automatically turns off. This is ideal for applications like garage door openers or momentary button presses. You can configure two wiring ways: turn on for 1s then auto-off, or turn off for 1s then auto-on.
- Self-locking Mode: The relay acts like a standard toggle switch. Pressing the button (in app or on remote) turns the relay ON, and pressing it again turns it OFF. This is suitable for controlling lights or other devices that need to stay on or off until manually changed.
- Interlock Mode: (Supported on 2-gang and 4-gang versions) In this mode, only one relay can be ON at a time. If one relay is activated, any other active relay in the group will automatically turn OFF. This is useful for controlling motors with forward/reverse functions or ensuring only one device operates at a time.
8. App Control (Tuya Smart Life)
Once paired, the Tuya Smart Life app provides comprehensive control and automation features:
- Remote On/Off: Control connected devices from anywhere with an internet connection.
- Timing Schedules: Set schedules for devices to turn on or off automatically at specific times.
- Countdown Function: Set a timer for a device to automatically turn off after a specified duration.
- Device Sharing: Share control of the device with family members.
- Group Management: Group multiple devices together for simultaneous control.
- Scene Automation: Create custom scenes and automations based on conditions like time, weather, or other smart devices.
8.1 Voice Control Integration
The device is compatible with Amazon Alexa and Google Home. After linking your Tuya Smart Life account in the Alexa or Google Home app, you can use voice commands to control your connected devices. For example:
- "Alexa, turn on Switch 1."
- "Hey Google, turn off the living room light."
Note: Currently, US/UK English and German voice commands are supported.
