Shelly Dimmer 2 | WiFi Smart Dimmer Switch | No Neutral Wire Required | Home Automation | Compatible with Alexa & Google Home | iOS Android App | No Hub Required | Wireless Switch | Dimmable Lights

These are extremely small, simple wiring, easy setup, and they just works. I highly recommend these. I just eliminated 3 dimmers in my kitchen with these relays.Instead of using switches we decided to use a tablet running home assistant to control our lights.I am new to Shelly products but so far so good 5x dimmers2 4x Plus1 1x H&T G3 1x 2pm and all have been plug play super simple to connect setup and use.Thanks Shelly!!!!

These are amazing! Literally any feature you could ever want are already included. This smart dimmer is really geared for makers and tinkerers and is obviously set up for being integrated into projects and other devices.I have it set up to control and dim a string of 10 LED under cabinet lights in my kitchen. It even has switch inputs that are completely configurable so you can retain physical controls. Their website even has Arduino integration tutorials!I love that it automatically calibrates the 0-100 brightness settings so you have a full usable range. It also tracks power usage! You can even have it ping webhooks!I had this set up and integrated with Google Home in minutes.Absolutely the best home automation purchase I've made in years of not ever.

Genial

I really wanted to like this thing, I really did. Installation wasn’t too hard, but after getting it installed, setup and configuration was a NIGHTMARE. There is no manual adjustment for dimming calibration, the app is kind of clunky and doesn’t make much sense, and to top it all off, if the lights are set to any less than 100% brightness, they flicker bad enough to make you turn them all the way off. Waste of time and money, I won’t be buying anything Shelly ever again.

Let me start by saying I LOVE these dimmers. They work flawlessly once installed—smooth dimming, seamless integration with Alexa and Home assistant, and no neutral wire required (a lifesaver for older homes). They’ve turned my basic light switches into one of the best parts of my house. Now my porch lights turn on when my cameras are triggered, and when I am close to home, but stay off the rest of the time, helping to reduce light pollution in my area.But here’s the catch: installing these bad boys with the included diagrams was like solving an escape room designed by an electrician with a sense of humor. The instructions were just clear enough to give me hope and just confusing enough to make me question my life choices. I had to YouTube my way through it, and even then, there were moments I considered calling a professional, and I did have to call my father in law.Now that they're installed? They’re amazing. The dimming is smooth, the app is intuitive, and the lack of a hub is a huge plus. These switches deserve 5 stars for performance, but they lose a star for not being DIY-friendly.Pro tip: If you’ve never wired anything before, maybe watch a few installation videos before you buy—or make friends with an electrician.Bottom line: If you can figure out the installation process (or survive it), these dimmers will change your lighting game.

The Shelly dimmer was easy to install and had many more features for really complex needs. I inserted it in a magnetic led transformer to manage on/off and dimmer function through my Amazon interface. It works flawlessly. Directions are brief, but there are RSS streams and videos on automation that can assist one with whatever their need. Coincidentally, mine was minor and it was harder to find basic use instructions.

Purchased on August 5, 2024. In mid-April 2025, it died. I'm giving 3 stars just because of its great functionality and the promise of a better product. However, it’s ultimately useless because the low quality of the assembled components cannot even withstand one year of operation.

We had a smart microwave that the light would automatically turn on at night and when we go rid of it and put in just a hood over our stove my wife wanted the light to come on automatically. This product worked beautifully. The wiring took a little bit of Google electrician to get right since it can be wired a few different ways and to make the switch still functional. Also it will set a passcode by default and it is hard to find what the default code is on the instructions but it is there. 0000 if you need. After it was done it performs great band does exactly what I need. Make a switch that cannot be smart smart controlled.
