Smart 1 Gang Relay Switch | AC or DC, 10A, and 433MHz | Tuya Smart Life
The Smart 1 Gang Relay Switch is a specialized low-voltage smart relay module designed for DIY automation. It combines WiFi, Bluetooth, and 433MHz RF control into a single unit, making it a “hybrid” switch that works with both smartphone apps and physical remote controls.
Product features
- Dual power input: It can be powered via the AC or DC terminals or a 5V micro-USB port.
- Scheduling and timers: set automated routines to run high-energy devices during off-peak hours to save on electricity costs.
- Voice control: integration with assistants like Amazon Alexa or Google Assistant for hands-free operation.
- Dry contact relay: the switching mechanism is isolated from the device’s internal power supply. This allows you to switch different voltages or simply “close a loop” without introducing any new current into the target circuit.

Nice little unit.Perfect for my application. I took this unit so that I can power it via USB from from my Gizzu UPS so the unit stays on, connected and operational even if Eskom steals our electricity for a few hours. I definitely recommend buying from this website. No hassles and fast delivery. Will definitely be buying more “gadget stuff”

Excellent product and purchased both versions ie AC mains and DC versions and they work very well and real easy to setup. I really like the fact that they have plastic cases for electrical protection and esthetic appeal. The size is small and I managed to fit the unit inside the light switch to control an outdoor flood light. Highly recommended.
