DC Relay Smart Switch – Tuya Smart Life WiFi Module with RF Support (7V–32V)

Description

The DC Relay Smart Switch is a compact yet powerful solution designed for people who want smarter control over their electrical devices without replacing their existing wiring. Whether you are upgrading your home automation setup, working on a DIY project, or automating low-voltage equipment, this smart module gives you reliable control through the Tuya Smart Life app with added RF remote support for extra convenience.

This intelligent WiFi relay module works on DC power from 7V to 32V, making it highly flexible for different applications such as lighting systems, access control, garage doors, pumps, fans, and other low-voltage appliances. It connects directly to your WiFi network, allowing you to control connected devices from anywhere using your smartphone. Even when you are away from home, your appliances stay under your control.

Unlike ordinary switches, this DC Relay Smart Switch functions as a relay without output power. The DC power supply is used only to operate the internal circuit board (PCBA), while the relay itself acts as a dry contact switch. This design makes it suitable for automation projects where safety, precision, and flexibility are required.

Using the Tuya Smart Life app, available on both Android and iOS, you can turn devices ON or OFF instantly, set schedules, and manage multiple devices in groups. The interface is simple and user-friendly, so even first-time users can set it up easily without technical expertise. You can also share device access with family members, making it ideal for homes, offices, or small commercial setups.

One of the standout features of this DC Relay Smart Switch is its RF (433MHz) support. While the product does not include a remote control, it supports compatible RF remotes, giving you an additional control option when WiFi is unavailable. This makes it a practical choice for environments where stable internet access is not guaranteed.

For hands-free control, the module works seamlessly with Amazon Alexa and Google Home. Once connected, you can control your appliances using simple voice commands. Whether you’re relaxing on the couch or busy in the kitchen, voice control adds comfort and efficiency to your daily routine.

The module also supports momentary (inching) mode, which is especially useful for applications like door locks, garage doors, and gate systems. You can customize the inching time directly from the app, ensuring precise control according to your needs.

Another major advantage of this DC Relay Smart Switch is its compact size. It can easily fit inside electrical boxes, control panels, or project enclosures without taking up much space. Despite its small form factor, it delivers stable performance and long-term reliability.

This smart relay module is ideal for users who want automation without complexity. From home automation enthusiasts to professional installers, it offers a balance of smart features, compatibility, and ease of use. If you are looking for a dependable WiFi relay that supports RF control and works with popular smart home ecosystems, this device is a solid choice.

In short, the DC Relay Smart Switch brings intelligence, flexibility, and modern control to your electrical setup while keeping things simple and practical.

👥 Device Sharing & Group Control

You can easily share access to the Smart DC Relay Switch with family members or colleagues through the Tuya app. Multiple users can control the same device without needing separate setups.
