Due to popular demand, SONOFF eventually releases a new D1 smart dimmer switch. It excellently improves the lighting system in your home with different brightness levels. Turn on/off, brighten and dim the incandescent light bulbs and dimmable LED lights through the RM433 remote controller, eWeLink APP, Alexa or Google Home. The newly added sunrise and sunset mode are available in smart scene to activate your light when sunsets and inactivate it when sunrises. Amazingly, timing schedule and brightness setting can be enabled simultaneously in smart scene. It means that you can schedule the bed-room light to automatically turn on at 40% brightness at 7:00 AM and turn off at 100% brightness at 7:00 PM. There is a base for the RM433 remote controller which is used to be directly replaced your light switch and installed into the 86 type mounting box, everything looks perfect. Besides, the dimmer can be installed into the EU and US type mounting box. For the protocol document and the code for the DIY Mode tool (updating), please go to http://developers.sonoff.tech/sonoff-diy-mode-api-protocol.html


Note: the RM433 remote controller and base are not included.

    A sub standard dimmer with ghost switching.

    I bought this dimmer in may ’22, and there seems to be two major issues with it.
    First, it happens to automatically turn on by itself(just to add more detail, I haven’t set up any trigger,schedule or scene), yet it randomly turns on or increase the brightness to 100%. I looked on internet and found that this problem is here from last 2-3years.
    Second, the dimming range is pretty low, after 60% there seems to be a negligible change in the light, and anything below 10% will cause light to flicker(previously I was using a normal dimmer which was working pretty well, whereas with sonoff is having quite a bit trouble here)

    I can still manage to live with second issue but the first issue is just ridiculous, it seems like sonoff is absolutely not bothered with what crap they are launching and not even want to address the age old problems in its dimmers.
