Leviton Decora Smart Controller Switch, Wi-Fi 2nd Gen, Neutral Wire Required, Works with My Leviton, Alexa, Google Assistant, Apple Home/Siri, & Wired or Wire-Free 3-Way, D2SCS-1RW, White

I give it 4.5 stars. For something that has a lot of software in it and sends messages to AWS in Virginia and back to control my light scenes, it is surprisingly fast and reliable. Also easy to setup by creating scenes on the app. My only complaint is... You can't use the bottom button for a fourth scene. I don't have this wired to anything, so the bottom button is worthless for me, and I think 90% of users would really like the option of using it as another scene.

This device spends most of the time off- line and doesn't work. Getting Customer Service to help me has been one of the most frustrating experiences. Do yourself a favor and go with the Lutron system instead. The wifi protocol used by Leviton is just crap.

If you have an automated home lighting system, this switch works well to control lighting for example in your kitchen where you have say: Recessed Lights, Under Cabinet Lights, Over The Sink Light, Over The Island Lights on switched separate circuits but don't want or don't have a convenient co-located 3-way switches for everything. Like All Leviton Automated Switches Very Easy to install and program. For Example: What I did is replace the over the sink light with this controller, to control the sink overhead light and the other 3 automated circuits (the other 3 circuits are on 3 separate automated switches). It is WI-FI !!! And stays programmed even after a power failure.

Works great in Home Assistant. I have the bottom button controller the hardwired 3 way swith AND another light. I have the top 3 buttons setup to toggle 3 other lights. One of them I even have setup to toggle multiple lights at once. Great product. Only thing to make it better would be Matter support.

Like the other Leviton smart switches, this works really well. A small physical annoyance unique to this 4 button switch that I don't really like the feel of the button presses (hard to describe, but not a very firm push or click or etc, so sometimes you aren't really sure you pushed it hard enough, or in the right place, or not). Another thing to note is that the 3 upper buttons only control 1 scene each. That means that any push of the button triggers the same scene. Apple's Home app doesn't easily let you create a "toggle light" scene. So if you want each button to first turn a light on, then on the next push to turn it off, you need to go through some hoops to convert the Apple Home scene into a "shortcut" and then use IF/ELSE conditions in the shortcut to make this work. This is really an Apple Home limitation, but something to be aware of since there is really no way to make it work without these steps. After that setup, the button does work perfectly fine to toggle a light, but note that the response time is a bit extra delayed (2-3 seconds between button push and action... again, likely this is a result of the need to setup the special Apple Home shortcut that has to run, and not caused by the switch itself)

Easy to install and adds control possibilities for several different scenes or devices.

"no hub required" right on the box Works as a homekit smart switch with no hub. The other 3 buttons are useless unless you have a hub or compatible leviton products.

Easy to set up. Works good. Easy to wire. Expensive, but worth it. I use mine as a kill switch for the house, because everyone leaves everything on in my house, no matter how much I complain.

These switches work as advertised. It is nice to turn the outside lights on/off from the phone - especially if you end up coming home in a rural area after dark. The feature within the App to group switches together allows one 'click' to turn all lights in the group. Programming the top three buttons to trigger any action set up in the App also allows one light switch to turn on all the outside lights in the group also.

Excelentes ,con cosas por mejorar: notificaciones de haberse realizado una acción, El grabado de los botones y en términos generas súper bien . Requieren de internet paran funcionamiento de las escenas .si NO hay sigo,las escenas no funcionan. Por lo demás EXCELENTE
