This document provides instructions for the QIACHIP Ewelink WiFi Wireless Smart Relay Module, Model KR0548-4CH. This smart switch allows users to remotely control connected home appliances or devices via the eWeLink application. It supports third-party voice control systems such as Amazon Alexa and Google Home, and can also be controlled by a 2.4G remote. Key functions include timer on/off, scene linkage, power-on status settings, inching mode configuration, and sharing control.
The module features a signal indicator light and a relay pull-in indicator light. Its board power consumption is less than 1W, with a quiescent current of 80mA. The rated switching current is within 10A, and the switching voltage is within 250V. It utilizes a 10A relay with a life expectancy exceeding 1,000,000 operations. Electrical insulation resistance is 100M, and electric shock withstand voltage is 1000V. The maximum pull-in time of the relay is 15ms, and the maximum release time is 5ms. It operates within a temperature range of -40 to +70 degrees Celsius and a humidity range of 40% to 80% RH.

2.4 eWeLink App Setup
To control the module via your smartphone, follow these steps to set up the eWeLink app:
- Download eWeLink-appen: Søg efter "eWeLink" in your smartphone's app store (available for iOS and Android).
- Registrer/Log ind: Opret en konto eller log ind, hvis du allerede har en.
- Gå ind i parringstilstand: Power on the relay module. Observe the WiFi network indicator light. If it flashes two short blinks followed by one long blink, the device is in pairing mode. If not, press and hold the setting button on the module until this pattern appears.
- Tilføj enhed i appen: In the eWeLink app, tap the "+" icon or "Add Device" option. The app will search for nearby devices.
- Connect to 2.4G WiFi: Ensure your smartphone is connected to a 2.4G WiFi network. The module only supports 2.4G WiFi; 5G WiFi is not supported.
- Fuld parring: Follow the on-screen prompts in the eWeLink app to complete the pairing process. Once successfully added, you can rename the device and control its channels.

3. Betjening
3.1 Arbejdstilstande
The module supports different working modes, configurable within the eWeLink app:
- Self-locking Mode (Default): In this mode, each channel acts as a standard on/off switch. Once activated, it remains in that state until manually changed.
- Krybningstilstand: In this mode, the device turns on and automatically turns off after a set interval (e.g., 1 second). The interval time can be adjusted in the app. This mode is suitable for applications requiring momentary contact, such as garage door openers or pulse-triggered devices.
3.2 Stemmekontrol
The QIACHIP Smart Relay Module is compatible with Amazon Alexa and Google Assistant. To enable voice control:
- Ensure your eWeLink account is linked to your Amazon Alexa or Google Home account through their respective apps.
- Discover devices in your Alexa or Google Home app.
- Once discovered, you can use voice commands (e.g., "Alexa, turn on Channel 1" or "Hey Google, turn off the living room light").
