TREATLIFE 3 Way Smart Switch 4 Pack, 2.4GHz WiFi Smart Light Switch 3 Way, Works with Alexa, Google Home and SmartThings, Remote Control, FCC, Schedule, Neutral Wire Required

They work great, except they're a bit large considering the size of the 3-way cables. You just need a lot of patience and care during installation, as you'll need all 5 cables to connect. The click when it turns on and off is very soft, and it has a small light that tells you whether it's on or off (which you can turn off via the app). It's very easy to set up for Wi-Fi in just a few minutes.

I just installed the 3-Way Smart Switch in my hallway, which has multiple switches controlling the lights. No issues with installation at all. I now have most of the house on a combination of regular switches, dimmer switches and 3-way switches, all from TreatLife. They're straightforward to install and set up in their app. Once that's done, I pop over to the Alexa app and add them as new devices. I can now control nearly every light in the house with these switches and they work great.The switches are good quality and I haven't had any problems with them. I don't know about other switch brands, but TreatLife products have worked great for me. Here are some tips I've learned:- They're bigger than regular switches, so make sure you push all the wires to the back of the box- Go slow. Don't pull all of the wires off of your old switch before installing the TreatLife switch. Transfer one wire at a time. Also, use their stickers before you remove the old switch so you'll know what each wire is- Get yourself a simple voltage tester. I bought a Klein Tools Voltage testers from Home Depot. Turn it on and the base is green. Put it up to a wire and if there's juice flowing to it, it the tester beeps and the tip turns red. The few dollars you spend on that tool is well work avoiding being shocked by a live wire!- If you use Alexa, make sure to add the new TreatLife switch as a Light, not a switch. That will allow you to control it with voice commands and create routines (great if you travel--you can have lights go on and off as if you're home)- Make sure you first recognize your new TreatLife switch in the TreatLife app. Then add it as a new device in the Alexa app. TreatLife has improved their app so some of the "I can't find the switch" errors have been cleared up. I installed five new switches and the TreatLife app found each one after a 45-second search- As with any home project, be safe. If you're uncomfortable working with electricity and wiring, ask a friend to help or hire a qualified electrician

Easy to install and connect to my wifi. I can now manage lights using the app from anywhere. I have 6 of them in use and all work flawlessly.

First the good: Once installed, these generally work just as you expect, interact well with the SmartLife app and Alexa, and all of the features (timers, schedules, remote on/off, etc.).Drawbacks: There are a couple of quirks that you need to be aware of: (i) if you happen to have a dimmer on your 3-way circuit, that is the one this switch needs to replace -- it is not that this switch includes a dimming function, but at least in our home having the dimmer on the other end of the 3-way circuit caused this switch to frequently short if the other switch with the dimmer was in one of the toggle positions -- take the dimmer out and this works great; (ii) this does not seem to have a positive "off" when toggled to open the circuit - there seems to be some very low level voltage leakage (not at all unusual with a 3-way switch), regardless of what position the other switch on the circuit is in -- so if you are using with just a single LED light, that very low level of leaking voltage can cause the LED light to glow dimly (because LED lights need so little energy to glow slightly) -- in our home, if there are 2 or more LED lights on the circuit, or an LED light + any other load, the voltage is not enough to cause any glowing. Also, beware that it is very challenging to fit two of these in the same box -- they are deeper than a simple toggle switch and the box needs to have room for the switches + all of the wires.

I’ve dealt with the GE brand smart switches for the last 7 years and I’m never going back, these are far superior to them in every way (Price, response, installation, reliability, and even look)I’ve had to replace my old GE switches about every 1.5 to 2years as they would constantly go out, yes they were under warranty (the first time) but what a pain in the a** to deal with that regular change. I bought one of these dimmer switches 5yrs ago on a whim because it was on sale and it’s never given me an issue once and the on/off response is instant not delayed like the GE. Even the fact that the 3-way switches can work with the old existing 3-way switch is a major plus, GE makes you buy a $20 add on huge switch just to have 3-way capability so $60 total to have a GE 3-way functional light compared to TreatLife $17. This brand is cheaper in price but not in value at all such a better quality product and a great affordable price. Will be switching everything to this brand from here on out.I use the smart life app and it’s great I highly recommend anything this company produces and look forward to what they put out next!
