I. Core Highlights: Smart Remote Control, Dual Working Modes
This dry contact WiFi relay switch is designed for home intelligent control, integrating WiFi connectivity and relay functionality to realize remote management of electrical devices. As a practical wireless remote control switch, it supports both normally open and normally closed working modes—suitable for different scenarios such as door control, lighting, and small household appliances, solving the trouble of "needing to manually operate devices on site".
It is also compatible with smart control ecosystems, supporting APP remote operation, voice commands, timing countdown, and group control. Whether you are at home or away, you can easily control the switch status of connected devices, making daily life more convenient and efficient.

Description
Product Type
Dry Contact WiFi Relay Switch (with smart control module)
Working Modes
Normally Open (NO), Normally Closed (NC)
Control Methods
WiFi (APP), Voice Control (third-party assistants), Manual Operation
Smart Functions
Timing Countdown, Group Control, Device Status Check
Compatibility
Suitable for door control, lighting, small household appliances
Core Advantage
Wireless remote control, dual working modes, wide scenario adaptation
III. Smart Control Functions: Multi-Dimensional & Convenient
1. APP Remote Control
Through the matching smart APP, you can realize long-distance control of the relay switch anytime and anywhere. For example, when you are on the way home, you can pre-turn on the connected lighting equipment via the APP—no need to fumble for the switch in the dark. This remote control on off switch function also supports real-time checking of device status, avoiding the worry of "forgetting to turn off the switch".
2. Voice Control
It is compatible with mainstream third-party voice assistants. You only need to issue simple commands such as "Turn on the door relay switch" or "Turn off the bedroom light relay", and the switch can respond quickly. This wifi smart switch feature frees your hands, especially suitable for scenarios where you are busy with housework or holding items.
3. Timing & Countdown
The timing countdown function can be set according to daily habits. For example, set the relay switch connected to the door to "automatically close after 5 minutes of opening", or set the lighting relay to "turn off at 11 PM on time". This not only simplifies operation but also helps save energy.
4. Group Control
If multiple dry contact WiFi relay switches are installed at home, you can group them (such as "living room group" or "entryway group") in the APP. With one click, you can control all switches in the group, avoiding the trouble of operating each switch separately.
IV. Applicable Scenarios: Wide Adaptation to Home Needs
Door Control: Connect to door access devices, use the normally open/normally closed mode to control door opening and closing, and support remote unlocking via APP.
Lighting Control: As a wireless switch for light, it connects to home lighting, realizing remote on/off and timing control of lights.
Small Appliance Control: Match with small household appliances (such as exhaust fans, small heaters), and use the relay switch to control their power supply, ensuring safety and energy saving.
V. Simple Operation: Easy to Get Started
Device Pairing: Power on the relay switch, connect it to the home WiFi via the APP, and complete pairing with simple steps.
Mode Setting: In the APP, select "Normally Open" or "Normally Closed" mode according to the connected device (e.g., door control usually uses normally closed mode, lighting uses normally open mode).
Function Configuration: Set timing tasks, group management, or voice control authorization in the APP—all operations are visualized and easy to understand, even for the elderly.
