1. Istruzioni per il cablaggio
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.

Image: Wiring diagram illustrating how to connect the input power (AC 85-250V or USB 5V) and the output to a load (e.g., a light bulb) using the NO and COM terminals.
- Potenza in ingresso: Connect AC 85-250V to the "Input AC 85-250V" terminals or connect a 5V USB power supply to the USB port.
- Connessioni di uscita: 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.
- Scarica l'app eWeLink dall'App Store (iOS) o dal Google Play Store (Android).
- Registrati o accedi al tuo account eWeLink.
- Power on the Wengart Smart WiFi Relay Switch.
- 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.
- In the eWeLink App, tap the "+" icon to add a device.
- Segui le istruzioni sullo schermo per connettere il dispositivo alla rete Wi-Fi a 2.4 GHz.
- Una volta completata l'associazione, è possibile rinominare il dispositivo e i singoli canali all'interno dell'app.
Modalità operative
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).
- Modalità autobloccante: 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.
- Modalità di interblocco: 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.
- Modalità di avanzamento lento: 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
