Smart 2 Gang Dimmer Mini Switch | Light Switch | Tuya Smart Life
The Smart 2 Gang Dimmer Mini Switch is a compact, retrofittable relay designed to sit inside an electrical wall box, effectively turning a traditional light switch into a smart device. Because it uses WiFi, it connects directly to your router without the need for an additional hub.
Unlike a standard smart switch, this module uses TRIAC (Edge Cut) technology to vary the voltage sent to the bulb, allowing you to adjust brightness levels from 0 to 100%.
Product features
- Physical design: these modules are typically very small, designed specifically to fit behind a physical switch inside a standard conduit box.
- Smartphone control: once paired with the Tuya smart app, you can toggle the power from anywhere in the world.
- Manual override: a critical feature is that your original wall switch remains functional. The module detects the state change of the physical switch and toggles the light accordingly.
- Voice integration: it is compatible with major voice assistants like Amazon Alexa and Google Home.

Works as well as expected. The problem is it’s a little bulky and doesn’t fit together with the Smart light switch.

Great product. Easy to use on application. However if you are planning to add the device to Home Assistant through the Tuya Local integration you need to use the smart life app and not the Tuya smart app.
