Smart Light Switch, 3-Way WiFi Dimmer Switch Compatible with Dimmable LED and CFL, Work with Alexa and Google Assistant, No Hub, Neutral Wire, ETL and FCC Listed, Minoston (MS10W)

This was fairly easy to install following the directions. It does changing some of the wiring to the switch, but once you figure out your wiring scheme it's easy not too bad. Directions did a good job of laying out the wiring.The switch integrated perfectly with Google but you do need to install a secondary app (instructions included) and then you can link it to Google Home. It's given me zero issues since installation. I did not integrate with Alexa.My one complaint with this switch is that it doesn't have a very sensitive dimming function. It seems to be more of a 0%, 25%, 50%, 75%, 100% output, rather than the fine tuned dimming my old, not smart dimmer switch was capable of. This wasn't a deal breaker but something to be aware of if you like to dim the lights to nearly off as this is not possible with this switch.

TLDR I liked these so much, I have decided to replace all the switches in the house with them.Pros? Obviously number one is it can be voice controlled. It can handle 3 way installation (though it is a different wiring required than traditional 3 ways but traveler, line, neutral and load are all there - not hard to master and is arguably easier overall). It can dim. It looks essentially the same as the rocker switches we already had in the house. It can connect via the Smart Life app, which I had already used for other devices in the house, and can therefore be controlled by Alexa (or Google if that's what you use). All the same benefits from that are therefore also available for these switches (can name individually, and add to routines easily, group the same switch to multiple different groups like Office, Inside Lights and Christmas Lights for instance).Those were the reasons I tried it out. Then, when I received them and looked at the instructions, I was blown away with the extra features it had that I had no idea I wanted so badly, but when I found out about I realized that I did. Now these are my favorite switches, and I can't imagine anyone else coming close.Extra features (all of which can be set on the switch individually after installation at any time):Minimum and maximum brightness setting. Does exactly what it says. Now when Alexa says my light is at 1%, in fact it is set to whatever the minimum brightness setting I manually set for that light. To be clear, Alexa will still report the light is from 1% to 100%, but the "1%" amount of actual light emanating from the LED can be set manually, and may be put at what you used to call 20%. You'd do that if you cannot detect any difference between 10% and 20% say (which I couldn't). If you make the 20% the minimum, now telling Alexa 1% sets it to the 20% amount, and then increases from there will actually result in detectable increasing light amounts.This feature also eliminates the flicker problem for some LED lights because you can manually set the minimum. Incidentally, none of my LED light flickered at all even at 1% brightness with these switches, but others have had that type of problem. Seems to me that this setting solves that problem.Lastly, this feature also means I can use the dimmer safely on my ceiling fan, which you normally should not do, because I can set the minimum brightness to be the 100% amount, and then when I turn it on (and the software slowly ramps up the brightness from 1% to 100%) it does not cause the fan to actually receive too little power which can burn up a motor in the fan when left in that state for long periods. To be clear, it does not enable the dimmer to actually control fan speed, but I knew that it wouldn't, and I was ok with that. If you want that, buy a fan speed controller and ensure the fan and light are wired separately.LED light state setting. You can set the light on the switch to one of four states. Always on, always off, only on when the switch is on, or only on when the switch is off. This enabled me to have the ceiling fan switch always show the little light off even when the fan is on, so it doesn't bug me in the dark when I leave the fan on all night like we always do. However, my other lights in the house can have the little light on when the switch is on, and be off when it is off so it acts as an indicator. For actual lights that's clearly not much of a benefit since you can usually just see whether the light is on, but for ceiling fans that are on, and you want to turn them off with your voice and be sure they turned off immediately, you can see that the light goes out, and you know the switch is off. Nice feature.Light off state setting. Sets whether the light slowly fades to off when turned off, or whether it turns off immediately. This was nice to set for the ceiling fans as explained above. Curiously, there is no corresponding setting for altering how the light turns on, which always fades on (which is why I needed the first feature for my ceiling fans).Power on state setting. For when the power comes back on after being cut for whatever reason, you can set the light to come back to whatever state it was on before, or come back on no matter what, or come back off no matter what. I just use the default for this one (the first one), but perhaps this might be useful in an office setting maybe... This one wasn't a big deal for me like the others were.Set whether up or down turns the switch on. If you want to make the down button action turn the light on, you can do that. Again, I used the default here, which is up turns the light on, and down turns it off regardless of the previous state.Flaws? Well, perhaps another setting to determine whether the switch fades on or comes on immediately. It surprised me they didn't have that considering the lengths they went to for the other features. Still though, I had never considered that this was a feature I would have wanted, and I was just fine with the fade to on. Kinda like it now actually.When the power goes out now, I find that some switches do not automatically connect back to the wifi. Best solution I've found is to cut the power at the breaker again, and give it another chance to auto reconnect. Usually works. And, to be fair, with the 14 or so devices I now have, maybe 1 or 2 might not auto reconnect after a power outage, and multiple times they have all reconnected just fine.Another flaw is the size. They aren't bigger than any of the others, but they're bigger than my old regular dumb switches, so it may make for a tight electrical box when you are done. I've had to use some force [on only 2 boxes] when screwing them in because the wires are just that bunched together because of the reduced free space in the box, but I think this is to be expected. The wifi controller has to go somewhere, and frankly I want it in the box and not outside!Another big flaw for my wife was the usage of them. They don't "click" into place up or down like our old rocker switches did, they "click" when you hit them up, but then it returns to the middle state. So, it feels more like a momentary toggle switch. However, there is just no way to have an Alexa controlled switch, and keep the same up or down rocker state that the old switches had. Otherwise, if you've changed the light state with your voice, then the switch on the wall would have to mechanically "switch" itself to the other side in order to show the correct light on or off state. Now, maybe someone will create that, but no one has yet, probably because that would then require a motor or solenoid now in the switch to alter the state, and there's likely no room to put that, and really do people want it? So, you just have to get used to the idea that hitting up turns the light on, or does nothing if it's already on, and then the switch goes back to the middle state, ready to accept another up press. I think my wife has gotten used to it now, as I had already, and this is not a problem anymore, but it was an initial complaint. Besides, the first time you say Alexa goodnight and all the lights go out, you forget this issue. As I mentioned before though, this rocker style switch is far better than the toggle style switches from other companies where it is just a big single push button that toggles the state. We both way prefer the two button (up or down) design.The last flaw is the price of course. Expensive to change out all the switches in the house... but they're about $22 or $24 after the coupon, which isn't terrible, and they may go down in the future.

It is too bulky to replace a normal three way switch; also, a rearranging of the wiring is needed to make it work.The manufacturer gives an extended literature to explain the settings for the WIFI part; but, for the electrical instalation, some unclear diagrams are provided.By mere coincidence I have the application that controls this device; so, to incorporate this dimmer to the group it only takes a few seconds.I don't like this dimmer; so I will replace with a《Maestro and Companion Kit》that includes two units that allows to dim the same light from the two locations or many more if needed.

Very nice! I didn’t like the fact that there is a slight lag in reaction time to turn the light off and on. I also didn’t like that it dims before turning off and brightens to whatever level it was on before when turning it on. I’d prefer it turn on directly at the right brightness and turn off immediately without dimming. I do like that you don’t have to keep tapping up or down to brighten and dim, you can just hold it until it reaches the right level. If it was a cheap dimmer I might be able to forgive these but as it is I will return for something else.

I was very skeptical after reading some negative reviews, but I installed this switch in a 4-way setup and it works flawlessly!! I’m not sure if the folks that left negative reviews just didn’t know what they were doing, but if you install this in the correct box (the one with the main power line) you should have zero issues.First off, I have about 12 or so different wifi switches—dimmer, single pole, 3-way, motion sensor, etc. but this one is probably the most solid build and compares only to the Lutron products I have as far as build quality goes. My other Wi-Fi switches are Martin Jerry, TreatLife, Wemo, TP-Link Kasa.This one looks simple but elegant and is very simple to use—compared to my 3-way dimmer switches made by Martin Jerry which are covered with different color LED’s and require a slave switch. This product, however, let me use my existing 3-way switches in a 4-way setup, which is absolutely fantastic!! I might swap out my Martin Jerry products for this one, because the look and functionality are just superb.Nearly allOf my existing Wi-Fi switches and plugs (including this one) all use the SmartLife app that allows me to mix and match switches and plugs while using just one window to control them all! Tested this with Alexa and Google and it worked instantly after installing the product on the SmartLife app.I think I just found my new favorite smart switch manufacturer. You can’t go wrong with this one, I highly recommend it!
