6. 설정 가이드
6.1. 장치 전원 공급
Connect a standard USB 5V power adapter (not included) to the Micro USB port on the module. The module will power on, and the Wi-Fi indicator light will begin to flash, indicating it is ready for pairing.
6.2. Wiring Diagram (Dry Contact)
The module provides a dry contact (passive output) relay. This means it acts as a switch, opening or closing a circuit without supplying power itself. You will need to connect the device you wish to control to the Input and Output terminals.

이미지 6.1: Examples of dry contact wiring for various applications.
- For AC Loads: Connect the module's output terminals in series with one of the AC lines (e.g., Live wire) of your AC device. The module itself is powered by USB 5V, not the AC line.
- For DC Loads: Connect the module's output terminals in series with the positive or negative line of your DC device.
- For Garage Door/Access Control: Connect the module's output terminals to the control input terminals of your garage door opener or access control system, which typically require a momentary contact closure.
6.3. 앱 설치 및 페어링
- eWeLink 앱 다운로드: 검색 "eWeLink" in your smartphone's app store (Google Play Store for Android or Apple App Store for iOS) and install it.
- 등록/로그인: eWeLink 앱을 열고 새 계정을 등록하거나 기존 계정으로 로그인하세요.
- 페어링 모드 시작: Power on the module. Press and hold the "on/off switch/setting button" on the module for approximately 5 seconds until the Wi-Fi network indicator light flashes rapidly.
- 장치 추가: In the eWeLink app, tap the "+" icon (or "Add Device") and follow the on-screen instructions to add a new device. Select the appropriate pairing mode (e.g., Quick Pairing Mode).
- Wi-Fi에 연결: Enter your 2.4GHz Wi-Fi network name and password. The module only supports 2.4GHz Wi-Fi networks, not 5GHz.
- 완벽한 페어링: 앱이 모듈을 검색하여 연결합니다. 연결되면 기기 이름을 변경하고 방에 할당할 수 있습니다.

7. 작동 모드
7.1. Self-Locking Mode (Default)
In self-locking mode, the relay acts like a traditional toggle switch. When you turn it ON, it stays ON until you manually turn it OFF. Similarly, when you turn it OFF, it stays OFF until manually turned ON. This mode is suitable for controlling lights, fans, or other devices that require a continuous ON/OFF state.
7.2. Inching (Momentary) Mode
In inching mode, the relay will automatically turn OFF after a set duration once it has been turned ON. This mode is ideal for applications like garage door openers, electric strikes, or pulse-activated devices. The duration of the momentary pulse can be adjusted within the eWeLink app (e.g., 0.5 seconds to several minutes).
To switch between modes, access the device settings within the eWeLink app and select the desired working mode.
8. 스마트 홈 통합
The QIACHIP WiFi Smart Relay Module is compatible with popular smart home platforms:
- 아마존 알렉사: Link your eWeLink account in the Alexa app to control the module with voice commands (e.g., "Alexa, turn on the garage door").
- 구글 홈/어시스턴트: Link your eWeLink account in the Google Home app to control the module with voice commands (e.g., "Hey Google, open the gate").
- IFTTT: Create custom automations and applets by connecting your eWeLink account to IFTTT (If This Then That).
Ensure your eWeLink account is bound and devices are synchronized within the respective third-party smart home applications.

- 전력 안정성: Ensure the USB 5V power supply is stable to prevent unexpected behavior.
10. 문제 해결
- Q: Device not connecting to Wi-Fi?
- A: Ensure your Wi-Fi network is 2.4GHz. Check that the Wi-Fi password is correct. Move the module closer to your Wi-Fi router. Try resetting the module by holding the setting button for 5 seconds until the indicator flashes rapidly, then re-attempt pairing.
- Q: Relay not responding to app commands?
- A: Verify the module is powered on and connected to Wi-Fi (solid blue indicator light). Check your internet connection. Ensure the wiring to the controlled device is correct and secure. Test the manual button on the module.
- Q: Voice control not working?
- A: Confirm that your eWeLink account is correctly linked and synchronized with Amazon Alexa or Google Home. Check the device name in the eWeLink app and use that name in your voice commands. Ensure your smart speaker is connected to the internet.
- Q: Inching mode duration is incorrect?
- A: Adjust the inching duration setting within the device's settings in the eWeLink app.
