I've used two or three different brands of smart switches over the years, and I've found that Treatlife smart switches just plain work. They're not expensive, but they're easy to install and pair with my system. I have them working through my Alexa device, and they work very well. Highly recommended brand.

Affordable dimmer, works with smart life app.

I gambled on a few boxes of these at a deep discount when they came out. But I hesitated to install them after I saw the plastic flange. Then I saw some unfavorable reviews. I just KNEW these were going to fail.In a pinch, I finally installed one. And I regret my initial judgment.They're not deep, so I didn't need to use the screws to pull it into the box. So, the flanges should live forever.Divorcing the power switch from the adjustment switches the way TreatLife did is genius. I get it that the lighting industry keeps the simple rocker because it feels familiar, and that most people are afraid of change. But a simple rocker just isn't adequate for adjusting output. I spend way too much time trying to reduce light to the minimum output without inadvertently turning the light off altogether. But these have a power switch, a low adjustment, and a high adjustment. It took a day or two for the critter who shares my house to get used to punching the main power button to turn them on (it's at the bottom, where the "off" side of a conventional switch is). But she picked it up quickly.These avoid that in at least two ways. The adjuster switches offer a number of output options that let the lamp get pretty dim. The app takes it one step further by offering a minimum threshold setting and three output modes to match various lamp designs. These switches get my lamps dimmer than any of my other switches, hands down. And the modes can eliminate flicker in some of the more finicky lamps. I tested an older compact fluorescent bulb on one. It wouldn't start in the lowest setting, but after warming up I could get it to go way dimmer than I could get that bulb to go with any other switch.The app is simple but effective. As mentioned, it offers minimum threshold settings and three modes of operation. But you can also turn off the night light that illuminates the power button when the switch is off.So far, the only thing that keeps them from perfection is no Z-Wave or Zigbee compatibility. Being WiFi only, they're limited by your router's range (the switches don't double as repeaters as they do in other protocols). Our house is small (1,300sf on two levels) with a low-tech mesh router, and the ones in the farthest corner of the house are a little slow to react and can sometimes fail to respond to hub commands.Being WiFi only, they don't offer acknowledgements to the hub to confirm the switch's mode. So, the hub doesn't know to resend the signal if the switch doesn't respond to commands. But that's a rare issue.A good mesh network should solve most of those problems. The ones closer to the primary router don't seem to suffer the latency and response failures.These are the ticket for those who don't want to invest in a hub that speaks Z-Wave or Zigbee. Even though we have a Z router, we still mix these WiFi switches with Z-Wave devices. And they work just fine. You just have to set them up in Alexa or Google Home before linking them to another router.I gave them four stars but I will also buy these again. They work really well and you can't beat the price.

Picture taken in very dark area led indicators hard to see, at day time impossible to see. Pairing not possible with best of my abilities. If compare with other brand which is green led light is much easy to install and better luminance in dark to find switch.

Installs easily for the second one. Learning to do first one takes a little time getting correct app. Works very well. I have 5 of them and my only issue is crosstalk from time to time resulting in two lights effected for one action. Have not resolved.

Purchased based upon looks, price and interoperability with my existing devices (Smart Life app). I was not disappointed. Received as promised and took about an hour to do the full install and connect to the app plus Alexa integration. I use it to control my back porch string LED lights. The switch is located inside the house by the rear door and replaces the existing standard toggle switch. Here's my advice on the install; Read the product details, you do need a neutral line (white wire) for this to operate. I've read reviews that state the unit is too deep in the installation box - i did not find this to be the case here. The depth of the unit is no different than any similar smart unit device (and i have many in the house from different brands). Instructions and clear and surprisingly in full English with color diagrams to match if you are unsure (i am an Electronics Engineer and come across many poorly translated user/install guides - this one is precise). The unit (dimmer switch) comes with a standard single gang wall plate attached - my installation was into a double gang and so i simply purchased a new wall plate and detached the unit from the provided single wall plate and it fits as intended into the double gang plate. There are retainer clips on the rear (plastic) - you simply ease them open and the unit detaches from the provided wall plate. Wiring is extremely simple - the user guide even shows you how to search out your existing toggle switch to determine which is your line and which is your load wires. The product also comes with pre-printed labels that you peel off and stick to the existing load/line conductors in the wall, to be foolproof if you are a novice. Labels are also provided if you need to identify your Neutral and Ground wires but these are self-explanatory by color. Of course, labeling is optional but good practice! The unit itself is clearly marked on the rear for all four connections (Load, Line, Neutral and Ground and also by standard colors). Upon power-up the unit has a backlit LED circle on the rocker switch. When operated there is a horizontal row of small white LED's at the top to show the dimming percentage (10-100%) approximately. Connecting to the wifi was simple and occurred first time for me (unlike other brands!). Make sure your mobile phone is on a 2.4GHz network if you have Dual bands in your home (2.4 / 5 GHz) in order to complete the setup. Then simply add the device per the app instructions...(interestingly, while my Smart Life app was scanning for the device, Alexa found it first and told me it was available!). Now i can operate and dim the lights by voice command and set timers and schedule from the app etc. All in all i'm very pleased with the purchase so much so that it's making me think about other lights in my home that i have yet to change out to the smart dimmers.

I bought this dimmer switch for my new chandelier light in my master bedroom. I use smart plugs with my Alexa throughout my home, but have never used a smart dimmer switch. After reading many reviews, I decided I liked the simplicity and styling of this dimmer switch. It appeared to have a more subdued operating/indicator light on it than brands, which was important for me so I could minimize the ambient light in my room for sleep. It was easy to install and pair with Alexa through the Smart Life app. It works great. So, I placed another order to get a second dimmer for my guest bedroom. This is a quality product.

We installed this in our future baby’s nursery. One thing I was concerned about which won’t be an issue is the glow being too bright when it is off but it’s only a slight glow and won’t light up the room. Followed the instructions to pair (with the Smart Life app I already had for other smart devices) and then it automatically connected to my Alexa. Like all smart switches/devices does not use 5g WiFi which is expected. It actually makes the light fixture brighter (on brightest setting) than the original toggle switch we had which is great. The default dimness is 10% but you can change that to 1% in the app (and also limit brightness as well). When using manually: I also like how it has a default brightness setting you can set up (super easy) where you click the on button twice and it goes to that setting (such as 50% or whatever you pick), and you can change the brightness BEFORE you turn it on (say you turned it off at 90% but want to turn it back on at 20%, you can turn it down before you turn it back on).

I liked the easy Alexa Integration..Works flawlessly...Installation was a challenge..The switch does not fit in a twin electrical switch box..The screws which join the two electrical boxes protrudes in the inside of the box which causes interference with the Smart dimmer switch..To fix this problem i grinded off to protruding screws and made them flush with the inside of the electrical box.That allows room for the Smart dimmer switch to fit properly..W.N.

Great product, this dimmer switch works very well, I used the smart life app from my phone, the switch connected instantly and showed up on my Google Display. It has many brightness levels, like 20, maybe too many but that's fine. It can easily be controlled from my phone, Google Home, Alexa, Google Nest Display or Sony android TV. Can also be used with automation and routines. I also got other smart switches and fan switches and all work fine.

This was easy to install (I have no electrical experience). Hardest part was finding the right breaker for the circuit. If you're organized and label your breaker panel like responsible adults do, it's a no-brainer to install the switch.The manual has clear and easy to follow instructions. It paired right away using the Smart Life app. Integrated with Google Home just by linking to Smart Life.All functions work as advertised.It will dim from 10-100%. Any lower and nothing happens.The only thing I will say is that the housing is cheap plastic, so be careful if you have to apply any pressure to get it into the wall box.The buttons' "clickiness" feels kinda cheap, but I'm using it mostly on automation and voice commands, so I've only pressed the button to test that I'd wired it correctly.I'd buy it again.

I needed a handyman for unrelated projects and had him install the switch, He said it was easy and the instructions were quite clear. I already own Treatlife smart plugs so already have the Smart Life app and the Alexa Smart Life skill and integration. (That was easy to do with the earlier purchases so did not need to do it again.) . I paired the switch to the Smart Life App very easily. The instructions are quite clear and easy to follow. I then, also easily, linked the switch to the Alexa app. And I was done. I had one issue that was an Alexa problem, not a Treatlife one. I could use voice and manual controls on the Smart Life App but only manual control on the Alexa app. I worked with the Treatlife customer support first and we could not solve the problem, but the Amazon customer support figured out that the problem was a naming one that the Alexa software didn't "like". Both the Treatlife and the Amazon customer support were outstanding. The Treatlife folks followed up several times to further troubleshoot without my needing to prompt them. I wish all technical support was this excellent. Once solved, the switch works perfectly and I can easily control the lights that the switch works by voice. One of the good features of this switch is the ability to turn it on and off and dim or brighten the light manually on the wall in the event that wi-fi goes down, The wall switch also has a very dim light at its on-off point; the light is just enough to see it in the dark but not obtrusive at night in a dark room (i.e., a bedroom). Overall, quite a good product coupled with excellent customer support.

Works well. No problems. Some things to note that I didn't read or recall reading. You can set the dimming to the level you want before you turn on the light instead of going balls to the wall bright and then turning it down. My lights can go all the way to 1% and that has to be set in the app because the switch defaults start at 5% because of cheap bulbs I assume. The switch saves your setting so you don't have to change it every time and there are lights on the top that indicate the level of brightness and light on the large switch as well that I didn't see in the ad images. Also realizing that I don't need 3-way switches where I want dimmers as well because with smart devices you can put the switch in the most convenient spot and if you are on the other side of the room you just have to tell it to turn on or off. Currently, I have a routine set that I tell Alexa goodnight when I get in bed and all of the lights turn off in the house and all of the TVs as well. Cool thing is that you can set the routine up to first dim the switch to 1%, then shut it off and go to bed. If you are like me and you get up in the middle of the night the switch will already be set to dim so you don't get blasted from dark to bright. Then in the morning I just tell Alexa good morning and the switches are set to 100% for the day. Connection to wifi was easy however I have no wifi dead spots because I installed a mesh network surrounding the entire home. The switch is better than I expected honestly and may have convinced me that this brand is the way I'll go. My only dilemma is having matching switches. That is hard to find in one brand when you need special features like 3-way dimmable switches. Some brands have them but then the other switches are just ugly or they don't match well.
