   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
