4. Setup and Installation
4.1 Wiring the Relay Module
The relay module offers flexible power input options and passive output contacts. Ensure all power is disconnected before performing any wiring.
- Power Input: The module can be powered via a Micro USB 5V/0.5A input or directly with DC 7V-48V. Connect the positive (+) and negative (-) terminals accordingly for DC 7V-48V input.
- Relay Output: The module provides dry contact output through three terminals: NO (Normally Open), COM (Common), and NC (Normally Closed). Connect your device's control circuit to these terminals based on your application's requirements.

4.3 Pairing the Module with eWelink
Follow these steps to connect your relay module to the eWelink app:
- Power on the relay module.
- Open the eWelink app and tap the '+' icon to add a device.
- Select the appropriate pairing mode (e.g., Quick Pairing Mode).
- Press and hold the 'Open the key / Pairing button' on the module until the Wi-Fi network indicator light blinks rapidly.
- Follow the on-screen instructions in the eWelink app to complete the pairing process, including entering your Wi-Fi network credentials.
5. Operating Modes
The DieseRC Smart WiFi Relay Module supports two primary operating modes: Inching (Momentary) and Self-Locking (Toggle). These modes can be configured within the eWelink app.
5.1 Inching Mode (Momentary)
In Inching mode, the relay will activate for a set duration (e.g., 0.5 to 3600 seconds) after being triggered, and then automatically deactivate. This is suitable for applications like garage door openers or pulse-triggered devices.
5.2 Self-Locking Mode (Toggle)
In Self-Locking mode, the relay acts like a standard on/off switch. One trigger activates the relay, and it remains active until another trigger deactivates it. This is suitable for controlling lights or other devices that require a continuous on/off state.
Image 5.1: This image illustrates the two operation modes: Inching mode, represented by a momentary push button, and Self-Locking mode, represented by a toggle switch.
5.3 Bluetooth Remote Control
The included Bluetooth remote control allows for local operation of the relay module. Each button on the remote can be paired to control specific channels or functions (e.g., ALL ON/ALL OFF).
5.4 APP Control (eWelink)
Once paired, you can control the relay module from anywhere using the eWelink app. The app allows you to:
- Turn devices on/off.
- Set schedules and timers.
- Share control with family members.
- Configure operating modes (Inching/Self-Locking).
