From the brand

Smart Dimmer Brand

Since 2017, we started to work on smart switches, from single pole to 3-way, dimmer to fan control. We are trying provide reliable and affordable IOT devices to our users.

How did we get our start?

Users know us from our 1st smart dimmer (MJ-SD01), which has a wide compatibility for different lamps.

From the first dimmer, we upgraded our design according to feedbacks from users, such as nigh light, auto dimmer, calibration, 3-way. Then, we win more and more users.

What makes our products unique?

We listen to our users. They want night light, we provide this feature. They like to link HA via MQTT, we provide tasmota pre-flashed devices.

Why do we love what we do?

We believe the IOT devices can really make our life easier and energy friendly.
