TREATLIFE Smart Dimmer Switch 4 Pack, Single Pole Smart Switch Works with Alexa and Google Home, Neutral Wire Required, 2.4GHz WiFi Dimmer Light Switch for LED, CFL, Incandescent Bulbs

Smart light switches at a great price (and good quality)
I bought a bunch of the Treatlife smart switches for my new home — we have mostly LED lighting throughout and I wanted to be able to control everything with my Google Home. These work super well and I’m keen to buy a few more of the 3-way switches when they’re back in stock.Pros:- Look really elegant and simple — I didn’t like the brands that have a bunch of buttons, this looks just like a normal switch and fits in with the others in my house- Works extremely well with Google Home and Assistant, I assume the same for Alexa- Installation is fairly easy for someone who’s relatively handy (don’t forget to turn off power at the breaker!) but a little tricky to find the neutral wire if your previous switch doesn’t have it- Routines — I have the porch lights on one of these switches and I have them automatically turn on (to a set brightness) at sunset and turn off at sunriseCons:- They’re not consistently in stock (which hopefully they’ll get better at over time)- Every once in a while the status light on the bottom glows red, and we can’t figure out why. The lights still work and respond to my voice actions, just glow red…- The color is a slightly bluer white than my other switches, but your milage my vary and I plan to update all my switches anyway

Great dimmer switch! Very easy to install. Many different settings for compatibility.
Update:After 2 years: 2 of these switches have failed and had to be replaced. Not sure why, could possibly be because of power surge? Dropping 1 star.Original:These switches were very easy to install and look great in a multi-gang box, or as a single! The box only comes with plates for single installation. There are some good youtube videos online on how to install switches. The only difference between these switch and traditional switches is that these switches have a white wire that needs to be attached to the other white wires as well. If the switch/lights don’t turn on when the power is resumed, you probably need to swap your black wires.They have a touch-slide interface for manually adjusting the brightness of bulbs. They also have an increasing turn on and decreasing turn off, as not to startle or blind you as they turn on.The software has a great easy-to-use interface for changing the brightness of the lights, or you can simply ask your digital assistant to do it for you! Additionally, you can set up daily schedules to turn on and off the lights, or set up smart events that are related to other devices in the house. (If you turn on this switch, turn on other smart lights or smart bulbs in the house)You can set a minimum brightness, to avoid low-voltage flickering on some bulbs. There is also 3-different dimming modes. I can’t really explain them, but playing around with it, I found that some modes offered a smoother dimming then other modes, depending on the type of bulbs it’s used with.Make sure your bulbs are dimmable, and don’t use these on any other device besides lights. Don’t dim smart bulbs with a smart switch.

I installed a 4 pack on 1 Feb 2020. We have a single Google Asus OnHub that services our 3-story house including finished basement. The setup process was simple and worked flawlessly in all four installations. Here are the specifics;1. Living Room – 4xE26(A19) 8.5W bulbs in two (2) lamps, set minimum dimming to 1%, -56dBm2. Family Room – 4xE26(A19) 8.5W bulbs in two (2) lamps + 1 internal LED, set minimum dimming to 1%, -33dBm3. Cat Room – 2xE26(A19) 8.5W bulbs in one (1) ceiling fixture, set minimum dimming to 1%, -58dBm4. LG Kitchen – 2xE26(A19) 8.5W bulbs in one (1) ceiling fixture + 3xGU10 6W bulbs in one (1) ceiling fixture, set minimum dimming to 1%, -48dBmAll Wi-Fi connections are solid, i.e. no drops and of “Good” quality, the furthest distance from the Router is about 30 ft and all bulbs dim without flickering from 100-1%. I use the “Smart Life” and “Google Home” apps on an S9+ running Android 9.0 and on an iPhone X and we currently have two (2) Home Minis to control the switches. All switches function as expected and without incident. The bulbs are also as bright as they were with the original mechanical switches, i.e. no loss of brightnessI purchased these switches for two reasons;1. So that my wife could turn on the lights in several rooms where we have cameras so she could better see her cats while we are on vacation2. To turn lights on and off while we are on vacationIssues;1. It is easy to change the dimming level when turning the switch on and off. There is a different model that would make this less likely.2. I understood from the description that these switches had a random timer, but they do not. When I subsequently reviewed the description, I noted that the wording could be interpreted several ways, one of which is that the user needs to set up multiple schedules to emulate randomness. I have several “EcoPlugs” that have this “random” timer feature which I have typically used while on vacation.Overall, they work well. Cannot comment on the long term reliability yetUpdate: 7 July 2020- Replaced the OnHub with the Google/Nest WiFi Router as I now have ~50 devices on our private network. The new router is physically smaller but actually offers significantly better range.- Now have 8x DS01C (touch sliding dimmer switch), 4x DS02S (2-button dimmer switch) & 4x SS01S (non-dimming switch), all are single pole.- Confirmed with Treatlife technical support that the switches DO NOT currently support a random timer feature- Use 3 dimmers and 1 non-dimming switch to control 7 exterior lights from dusk to dawn- So far so good, no issues to date (~5 months of use)- I plan to add several Treatlife 3-way switches in the coming monthsUpdate: 22 Nov 2020- We’ve experienced two (2) power failures recently and I noted that most of the dimming switches revert back to the default 15% brightness despite my setting them to 1%.- Reliability after ~11 months of operation for the first group of dimming switches has been 100%. We have experienced no failures of any of the switches to date.- One other issue that I neglected to mention previously relates to the installation. The switch housing is quite large and consumes most of the space inside the electrical box. I had difficulty installing the switches in several ganged boxes, as it seems that the original electrician created some of the ganged box from multiple single boxes rather than using a purpose built ganged box. As a result, there are small flanges inside the box that prevent the switch from seating properly, i.e. the housing will not slide into the box completely. I cannot change the box (obviously) so I had to cut the flange off, which as one might imagine was troublesome. This is not a criticism of the switch, it is just an example of a challenge that one might encounter due to the way the original boxes were made/constructed.- Another challenge with the multi-ganged boxes is the amount of cable, and I didn’t want to shorten the switch wires if at all possible, so it is a very tight fit.- The switch covers are larger than standard covers and in my opinion are more aesthetically pleasing since the screws are hidden. However, they only work for single boxes and most of my switches were installed into ganged boxes (see Pic). I ended up purchasing new switch cover plates that are very similar to the OEM plate, and these work well but do add to the cost of the installationLong Term (12 March 2022)I just ordered #17, the previous 16 switches are all performing well. The only other issue I’ve encountered is that one switch occasionally becomes unsynced from the rest when executing a smart action. I correct the issue by cycling the power to that switch, so I imagine resetting the switch would also work. This happens every 2-3 months. Also, a power outage to the house will correct the issue. Smartlife issues an alert when this event occurs so I am aware of it. BTW, the Smart action just runs these lights/switches from dusk till dawn.

Is a really good product man. It’s my go-to brand for using around the house. I’ve almost converted all of my switches to the app. Works great! Interfaces great with Google home and Alexa
