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.

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.

Just installed today
I got this for some nightstand pendant lights in my room. I needed something in the tuya realm to sneak onto my treatlife app. It installed as easily as any other smart switch and programmed the same. I originally missed that you can set the dimming range, but thereâs a tiny dial on the bottom of the switch if you pull it off the wall.Overall, I really like it. Thereâs a little button to toggle the switch light off and on, which is awesome in my situation. Itâs got good functionality, the dial is great and it seems like itâs good quality. If they begin to make multi location smart dimmers, Iâll completely switch over to them. So fingers crossed ð¤

This works with existing 3 way and 4 way circuits
This switch works with traditional 3 way and 4 way circuits. No special switches required for the other switches. No instructions were included but a quick internet search solved the problem. Easy to install.

Sent back for refund
The brown travel wire would not work. I had normal three way switches attached to this circuit and they work perfect. I worked with this switch for a long time trying to get it to work and finally tested the voltage coming out of the brown wire I realized that there was no voltage when the switch was toggled. I sent it back for a refund and ordered the other version this company has that doesnât have the dial but just a simple slide for your finger to adjust the brightness. Received it, installed it, and it worked perfectly.

Poor quality
I bought 4, one didn’t work straight out of the box ,one got ruined upon installation (wattage rating is a lie ,handles much less than the box indicates) , another one refuses to work with my existing regular dimmer switch (turns itself on after turning it off manually ), extremely poor quality , buying a more expensive brand name smart switch now because these where an absolute waste of money. Installed with a certified electrician.
