This document outlines the features, installation, and operation of a Wi-Fi Dimmer, model QS-WIFI-D02-TRIAC(RF). This device is designed to integrate into a smart home ecosystem, offering flexible control over lighting.

The primary function of the Wi-Fi Dimmer is to enable smart control of lighting, specifically triac LED lights, incandescent lamps, and halogen lamps. It acts as a dimmer module, allowing users to adjust light levels and switch lights on/off. The device supports both remote control via a mobile application and local control through a traditional push-switch or an RF controller.

Usage Features:

The Wi-Fi Dimmer offers a comprehensive set of features for convenient lighting control:

Global International Operation: Users can control their lighting from anywhere in the world using a single mobile application, provided they have an internet connection.
All-in-one Mobile App: The device is managed through a dedicated mobile application, which serves as the central hub for all smart lighting functions.
Schedule Timer: The app allows users to set schedules for their lights, enabling automated on/off times and dimming routines. This feature is useful for creating ambiance, enhancing security, or simply automating daily lighting needs.
Voice Control Integration: The dimmer is compatible with popular voice assistants such as Google Home and Amazon Alexa. This enables hands-free control of lighting, allowing users to adjust brightness or switch lights on/off using voice commands.
Device Sharing: The mobile application supports device sharing, allowing multiple users (e.g., family members or housemates) to control the same dimmer module. This eliminates the need for individual setup and provides shared access to smart lighting.
In-house Local Operation: Even without an internet connection, the dimmer can be controlled locally. This includes:
- Apps (via local network): When within the local Wi-Fi network, the mobile app can still communicate with the dimmer.
- Router: The dimmer connects to the home router for Wi-Fi functionality.
- Voice Control (local): If a local voice assistant device is present and configured, voice commands can still function.
- Push Switch: A traditional push-switch connected to the dimmer module provides direct manual control.
- RF Controller Control: The device also supports control via an RF controller, offering another layer of local, wireless control.
Manual Override Functionality: The dimmer module includes a manual override function accessible via the connected push-switch.
- Short Push (<1s): This action provides a permanent on/off function for the light.
- Long Push (>1s): This action allows users to adjust the brightness level of the light.
- Synchronization: Both app adjustments and push-switch adjustments can overwrite each other, with the last adjustment remaining in memory. The app control is synchronized with the manual switch, ensuring consistent status across all control methods.
- Unconnected "S" Terminals: If manual control is not required, the "S" terminals on the dimmer module can be left unconnected.
Wi-Fi Connectivity: The device operates on a 2.4GHz Wi-Fi frequency, ensuring compatibility with most home Wi-Fi networks. It is recommended to keep the smartphone close to the dimmer module during configuration and ensure a minimum of 50% Wi-Fi signal strength for optimal performance.
Offline Functionality: In the event of a Wi-Fi outage, the light connected to the dimmer module can still be controlled using the traditional switch. Once Wi-Fi connectivity is restored, the device will automatically reconnect to the network.

Maintenance Features:

While the manual does not explicitly detail "maintenance features" in the traditional sense (like cleaning instructions), it provides crucial information for troubleshooting and ensuring the longevity and proper functioning of the device:

Troubleshooting Guide (FAQ): The manual includes a comprehensive FAQ section to address common issues:
- Configuration Issues: Provides steps to troubleshoot problems during initial setup, such as checking power, Wi-Fi network (2.4GHz), internet conditions, app password, and wiring.
- Device Compatibility: Clarifies that the dimmer is primarily used for triac LED, incandescent, and halogen lamps.
- Wi-Fi Outage Behavior: Explains that local control via the traditional switch remains functional during Wi-Fi interruptions, and automatic reconnection occurs upon Wi-Fi restoration.
- Wi-Fi Network/Password Changes: Instructs users to re-connect the dimmer module to the new Wi-Fi network as per the App User Manual if the network or password changes.
- Device Reset: Details the procedure for resetting the device by pressing and holding the traditional dimmer switch for 10 seconds or more until the connected lamp flicks quickly, indicating entry into configuration mode. This is a critical step for re-pairing or troubleshooting.
Installation Warnings and Guidelines: These guidelines are essential for preventing damage to the device and ensuring safe operation, thereby contributing to its maintenance and lifespan:
- Qualified Electrician: Emphasizes that installation must be performed by a qualified electrician in accordance with local regulations. This prevents improper wiring that could damage the device or pose safety risks.
- Child Safety: Advises keeping the device out of reach of children.
- Environmental Protection: Recommends keeping the device away from water, damp, or hot environments to prevent damage.
- Signal Interference: Instructs users to install the device away from strong signal sources like microwave ovens to avoid signal interruption and abnormal operation.
- Obstruction Avoidance: Warns that concrete walls or metallic materials can reduce the effective operation range and should be avoided during installation.
- No Disassembly/Modification: Explicitly states that users should NOT attempt to disassemble, repair, or modify the device. This is a standard safety and warranty-related instruction, as unauthorized alterations can damage the device and void warranties.

By adhering to these installation and troubleshooting guidelines, users can effectively maintain the device's functionality and ensure a reliable smart lighting experience. The emphasis on proper installation and a clear reset procedure are key aspects of device maintenance from a user's perspective.
