Setup

1. Wiring Instructions

Before wiring, ensure the main power supply is disconnected to prevent electric shock. The device supports both AC 85-250V and USB 5V input. Connect your devices to the relay outputs (NO, COM, NC) as required.

• Input Power: Connect AC 85-250V to the "Input AC 85-250V" terminals or connect a 5V USB power supply to the USB port.
• Output Connections: Each channel has NO (Normally Open), COM (Common), and NC (Normally Closed) terminals. Connect your load (e.g., light, motor) between COM and NO for standard switching.
• Manual Switch Inputs (K1-K4): These terminals allow for external manual switches to control each channel.

2. App Pairing (eWeLink)

To control the switch via your smartphone, you need to pair it with the eWeLink app.

1. Download the eWeLink App from the App Store (iOS) or Google Play Store (Android).
2. Register or log in to your eWeLink account.
3. Power on the Wengart Smart WiFi Relay Switch.
4. Press and hold the "Reset" button on the device for approximately 5-7 seconds until the network indicator LED blinks rapidly. This indicates pairing mode.
5. In the eWeLink App, tap the "+" icon to add a device.
6. Follow the on-screen instructions to connect the device to your 2.4GHz Wi-Fi network.
7. Once successfully paired, you can rename the device and individual channels within the app.

Operating Modes

The Wengart Smart WiFi Relay Switch supports three distinct working modes, configurable via the eWeLink app:

Image: Visual representation of the three operating modes: Self-locking (independent control), Interlock (only one channel active), and Inching (timed pulse).

• Self-locking Mode: In this mode, each of the four channels operates independently. Turning one channel ON or OFF does not affect the state of the other channels. This is suitable for controlling individual lights or appliances.
• Interlock Mode: This mode ensures that only one channel can be active (ON) at any given time. If one channel is turned ON, any previously ON channel will automatically turn OFF. This is useful for applications where only one output should be active, such as motor direction control.
• Inching Mode: Also known as momentary mode, this allows a channel to turn ON for a set duration (e.g., 0.5 to 3600 seconds) and then automatically turn OFF. This is ideal for triggering short actions like opening a gate or pressing a button. The duration can be customized in the eWeLink app.

Remote Control and Voice Control

Remote Control via eWeLink App

Once paired, you can control your Wengart Smart WiFi Relay Switch from anywhere with an internet connection using the eWeLink App. The app provides real-time status updates for each channel.

1. Ensure your eWeLink account is correctly linked to your Amazon Alexa or Google Home account through their respective apps.
2. Discover devices in your smart assistant app.
3. Use commands such as:
   • "Alexa, turn on [Device Name]"
   • "Hey Google, turn off [Device Name]"
   • "Alexa, set [Channel Name] to on"

Intelligent Timing and Scene Management

Enhance your home automation with the timing and scene features available in the eWeLink App.

• Timing: Set specific ON/OFF times for your devices.
• Delay Timing: Schedule a device to turn ON or OFF after a specified delay.
• Cycle Timing: Automate devices to repeat ON/OFF cycles at regular intervals.
• Scene Management: Create custom scenes to control multiple devices simultaneously with a single tap or based on specific conditions (e.g., "Good Morning" scene turns on lights and coffee maker).
