This Smart WiFi Wireless Relay Switch Module serves as a compact and practical solution for integrating home automation into everyday electrical systems. Engineered around the Tuya smart platform, it provides a straightforward method for controlling a single channel (1CH) of dry contact momentary switching. The module accepts both AC and DC power sources ranging from 7 to 32 volts, as well as a standard USB 5V input, offering flexibility in installation scenarios. Its physical construction uses durable, fire-resistant ABS plastic for the enclosure, ensuring safe operation within rated parameters.

The internal circuitry is designed for reliable switching and stable performance over extended use, with clearly labeled terminals for easy wiring. The device functions as a dry contact momentary switch, making it suitable for controlling garage doors, gates, electric locks, and other momentary applications. Through the Smart Life app, users can set schedules, create countdown timers, and link the switch with other Tuya-compatible devices.

The module’s compact dimensions allow it to fit behind existing wall switches or inside junction boxes without occupying excessive space. Connectivity relies on standard 2.4GHz WiFi, requiring a stable network for remote operation. The switching mechanism is rated for a moderate current and voltage, ensuring it handles common household control tasks efficiently.

Compatibility extends to major voice assistants, including Amazon Alexa and Google Home, which allows for hands-free activation via voice commands. The module does not require a separate hub, as it connects directly to the home WiFi network, reducing setup complexity. Its affordability—priced at a very competitive level—makes it an accessible entry point for those exploring WiFi-based relay control.

The build quality includes strain-relief features on the terminal blocks, and the PCB is coated for moisture and dust resistance, enhancing durability in typical indoor environments. While it does not include built-in overload protection, proper fusing on the power side is recommended for long-term reliability. This switch module is particularly well-suited for DIY enthusiasts, electricians, and smart home integrators looking to add remote and voice control to existing dry contact loads without significant rewiring.
