    Works perfectly
    The switch was easy to install, came with clear easy to understand instructions and works perfectly. I had to do some fancy foot work to get a neutral into the box but it’s all good. Priced fairly and works great with Alexa.

    work great…and great customer service.
    You must follow the directions closely and study the wiring diagrams carefully. I have ordered 6 of these and have installed them both as 1 way and 3 way with no issues. I did have one stop working after the return period and I emailed eva logik support and they replaced the unit for free immediately.

    **Edited** This switch works fine after update
    What I liked, and what I wish all smart switches would have, is the terminal connections instead of “pigtail” wires. Most smart switches have individual wires coming out for each connection, which means you need to connect to your house circuit using wire nuts. Those wires and nuts take up a lot of room in a box, making it tough to stuff back in. This switch has push-in wire connections that are tightened with screw terminals. This makes it easier to install.**EDIT** I’m updating my review.First, their Support was on vacation, so it took time for them to respond to emails.These switches have internal firmware that can be updated through the Smart Home app. Support suggested updating this to fix the problem and now it works just as it should. No problems at all.One minor thing to know, though – The switch’s style makes it look like a typical Decora “rocker” style, which matches our Decora rocker standard switches, but it doesn’t behave like a rocker. Normally, pressing the bottom and top halves of the switches performs some function. For example, on a standard, non-3-way switch, pressing the top half turns the light on and pressing the bottom turns it off. However on this switch, only pressing the bottom does anything. If the light is on, it’ll go off, and vice versa. Pressing the top half does nothing. It would be better if it behaved like a standard rocker (top turns on, bottom turns off) or if you could press either top or bottom to turn the light on/off.||| Original part of the review below, which no longer applies if you update the firmware. |||vv vvThe downside is it doesn’t operate very well as a 3-way. For one thing, the paddle only works when youpress the top half. The bottom half doesn’t do anything, so pressing the top turns your light off and pressing again turns it on. **Except** for when you turn the line off and on from your breaker box. That resets the switch so it turns off when you press the paddle bottom and on when you press the paddle top. But only if your other, regular (dumb) 3-way, is in one certain position. If I switch that regular switch to the other, then it goes back to where only the smart switch paddle top does anything. But if you start doing “smart things”, like using the Smart Home app, sometimes you get it to where you can’t get the paddle bottom to do anything ever again (until you reset again). Does this make sense?”Smart” operation is also messed up. If I use Google Home or Alexa, I have to press the button twice to get it to switch from on/off. The first time you press, Home says the light is on, but it’s not. The next press turns the light on, but Home says it turned off. Another press does nothing with the light (it stays off), but Home now says it’s off.There are other weird happenings, but it’s tough to sort out all the variables. Like Alexa commands seem to work, but only if the regular switch is in the right position.I’ve tried chatting with Eva Logik, but they only say to email, and email gets no response. I’m going to return this and hope I can find a smart switch with screw terminals.

    Worked for 8 months then died
    Installed and configured easily. It worked well for 8 months, then is just went dead. Tried all of the software and reset suggestions from manufacturer website with no luck. Tested the circuit and it was perfect. Replaced the ‘smart’ switch with a regular 3 way switch for $5 from HD, and the it’s working, so the wiring is fine. Sent a message to the manufacturer seeking support and got no reply. Very disappointed.

    Good, except when it disconnects from wifi
    I love this switch. EXCEPT, when the device is disconnected from wifi. Then it keeps switching on and off. I thought maybe it was my common neutral, but switching it with another switch stopped the issue. It rather is annoying

    Best wifi switch
    ***Updated reviewPreviously, I said these were among the best — these are the BEST wifi switches on the market today. These switches use a proper wire terminal (no wire nuts needed), and have a METAL frame instead of thick, cheap plastic.Do not buy anything else. I also have the Eva Logik 3-way version of this switch and it also works in the same way.I have owned literally half a dozen brands of wifi switches and I am slowly replacing all of them with these. There is literally ZERO bad news with these and I cannot believe how cheap they are.**original review:These are among the best Wi-Fi switches because it has a frame for mounting it and wire terminals instead of wires. The metal frame makes it compatible with more light switch covers. If you use the plastic frame switch, it’s very hard to use screwless switch covers. The plastic frame switches are simply too thick. Secondly, other Wi-Fi switches have wires instead of wire terminals which requires you to use wire nuts inside the switch box. If you have an older house with shallow switch boxes, it makes it impossible to install the switch. Everything else about the switch is also A+. Set up was very easy. Just make sure to follow the wiring instructions if you are using it in a three-way circuit.

    Good product and Good size!
    This switch was just what I was looking for. I needed a three way dimmer that will work with the Smart Life app and my LED lights. After shopping around, I ran across this one and chose it because of the smaller form factor. I have an older home with metal junction boxes that are smaller that the newer plastic boxes. Most smart devices are big and bulky and have pigtail connections. That makes them hard to fit in the smaller boxes especially with the required wire nuts. This switch fits much better! It does require a neutral conductor and also needs to be installed in the location with line side rather than the load side which could be an issue depending on your installation. Otherwise, it is easy to install and configure with the app. The only downside for me is that it is not available in brown or black, so it kinda jumps out in my room. I may end up coloring it somehow.

    Best one you can buy
    I have 9 different brands of smart switches in my house over the years. this is by far the easiest one to set up. It almost set it self up, no really. I turned the power on after hooking it up and it took me a few min. to get to my phone and it was half set up already. It is also the smallest smart switch I’ve seen. This switch can be hooked up with a 3 way lights with just this 1 switch saving money. my 1st on is about 1 1/2years old and never had a problem with it. It has really good range on it. So far its the only one that will work in my work shop out back, the other ones I’ve tried will not reach that far.
