Tuya 2-Channel WiFi Relay Module – True Automation, Not Just a Remote Control
Looking to control your devices from anywhere without rewiring your entire electrical panel? This 2-channel independent WiFi relay module integrates seamlessly into your existing setup in minutes, giving you complete control via the Tuya Smart Life app — whether you’re using your smartphone, voice commands, or a physical RF remote.
Note: This module supports fixed-code 433MHz RF remotes. Rolling-code remotes, commonly used for garage doors or alarm systems, are not compatible.
Why choose this model? (Key Advantages):
- Control from anywhere — Manage 2 independent circuits via 2.4GHz WiFi directly from the Tuya Smart Life app, even when you’re away from home.
- 3 Configurable Operating Modes — Self-locking, Interlocking, and Inching (timer from 0.5s to 3600s) cover any scenario, from lighting to motor control.
- Physical RF 433MHz Backup — The remote works independently of the internet, ensuring you maintain control even if your WiFi connection drops.
- Alexa and Google Home Ready — Enjoy hands-free voice control without the need for additional hubs or complex configurations.
- Heavy-Duty Relays — Rated for over 1,000,000 cycles; this isn’t just a hobbyist module, it’s built for reliable residential or industrial use.
- Universal Power Supply — Flexible power options via Micro USB 5V or DC/AC 7–32V, making it easy to adapt to any project or electrical cabinet.
- Smart Sharing & Scheduling — Grant access to other users and set automated timers or schedules directly within the app.
Performance and Technical Details
Each of the 2 independent relays supports up to 10A (2200W), featuring switchable contacts between Normally Open (NO) and Normally Closed (NC) — ideal for ensuring a circuit remains active if the module loses power. WiFi communication on the 2.4 GHz (802.11 b/g/n) band ensures real-time status synchronization in the app. The integrated 433MHz RF receiver adds a layer of local control, and the compact design is perfect for standard DIN rail mounting.

Frequently Asked Questions
Is it compatible with all 433MHz RF remotes?
Not all. It works with fixed-code 433MHz RF remotes. Rolling-code remotes, often used for garage doors or security alarms, are not compatible with this module.
Can I control electric motors with this module?
Yes. By combining Interlocking and Inching modes, you can control low-voltage DC motors, including reversing rotation direction using alternate pulses on the two channels.
Does it work if I lose my internet connection?
App-based control requires an internet connection. However, if you have paired a 433MHz RF remote, it will continue to function independently of your network connection.
Can I set automatic schedules?
Yes. The Tuya Smart Life app allows for comprehensive scheduling — you can set devices to turn on or off at specific times or trigger them based on specific conditions directly from your phone.
Can I share access with other people?
Yes, you can share control of the module with other Tuya users via the app. Each user can operate the relays independently from their own smartphone.
