This smart switch comes with two sets of switches. Each set includes two wire nuts, two mounting screws, snap-on face plate, wire labeling stickers, and the switch itself.

Installed this in our garage to control floodlights mounted on the exterior of our home, When our house was built the switches for some reason were installed in the garage as opposed to in the main living area which made it a pain to go in the garage to turn the lights on, Now we just ask the Lady in the round thing(Alexa..lol) to turn them on and off. Definitely saves time when we need them on quickly. Was very easy to install with the instructions and videos provided on the product page( and a short YouTube Search) Very Easy to set up to work with Alexa.

Got the single switch on sale for $14.99. Excellent deal and value. From other reviews, I saw that the instructions were very easy to follow (they are provided in the app). I agree, though I may have misread something when setting up mine, because it originally wanted me to install two of them. Fortunately, this was not necessary and it works great to replace a single switch. In fact, my setup is a 4-way setup (3 switches). I figured I couldn't replace the "middle" switch, which is a 4-way, but this one worked great to replace the end switches (which are both 3-way). I was afraid I might need to replace the "lead" switch, but nothing in the instructions said this was needed, and it works great with the one I replaced. My house wiring wasn't done with the proper colors (travelers are supposed to be red wires, where one of mine is black)... but I know enough about wiring to figure that out. This switch has clear labeling to identify the traveler screws, so that made it easy. The white and green are wires coming out of the box, so those are easy. The only one left is the black, which is on a screw terminal. It was an easy install since I could remove the black on my existing switch, and then put the two travelers on, and then connect the white and green as usual. Everything worked great, app connected to wifi quickly and easily, and the indicators on the switch are a nice extra feature (to know that the wifi is connected). Would highly recommend this one, as the instructions were great, and the setup was flawless!

These 3 Way work. Now, I learned you don't "have" to put each one on the same circuit, so if you are okay going against the TP Link recommendation, since they come in pairs, you can put 1 on a plug and have it work, and put the other one on a different plug and name it separately, and BAM you have two 3 way circuits that are on your Alexa control (and Kasa App control etc). I do have some "4 way" switches.....and they area PAIN. I thought they were 3 way, and one of them I got to work (don't ask me how, ha) but the other I cannot. They have an extra wire, and it's a huge pain in the rump. In general, it's awesome though. I copied the review from the "smart plugs" as well, because all of the information is essentially the same, except for the install which for the switch you have to put in the wall switch (TURN OFF BREAKER< HA) and the plugs are just plug in and then the lamp or whatever goes in the plug. The switches you have to know how to wire in a replacement switch in the wall. I will say, these switches are much bigger than just a switch (inside the wall box). I've done other timer switch replacement, and that's the norm. The problem is a lot of these boxes have TONS of wiring stuffed into them. On a few, especially ones that have 3 or more switches in one long box, I've had to pull all of them and trim wires to make them fit. I didn't trim where they weren't workable, but I did get a ton of the excess removed. These plugs work....that’s it, they work. All of the TP Link smart home plugs and Switches work, and work flawlessly that I can see. The Kasa app is great, works flawlessly as well. I have 8 of these so far, and they are mixed in my home with wall switches (TP Link switch and 3 way switches) to all run with Kasa app that is TP link that then works with the Alexa Amazon Echo's throughout the home. These things are truly plug and play. You plug them in, open the Kasa App, and "add device" and bam, it's super easy to follow the directions and add to WiFi in the home. Then open Alexa App on the phone and all of these TP Link items are there in the Smart Home section. It just works, and works flawlessly. The entire system, I add "Routines and Scenes" and you can do all kinds of cool things. In the Alexa App the Routines, I can turn on lights and play the weather on the Echo and then have it start music. I can say "Alexa, turn on the Accent Lighting" and it turns OFF the ones that I want off and don't think are accent, and turns on the ones I say to turn on, and it is super easy. The Kasa app also has timers as much as you want. You can set "turn on" and the time, and create as many as you want, and turn off the same. My Christmas lights indoor and outdoor were all on these indoors and the plugs for outdoors are on switches, so bam those all worked on timers there. Same with my patio outdoor lights. The "only" glitch I've had in the months of using these......I switched Broadband Providers from Uverse to Spectrum. The new WiFi router, I set up the SSID to the exact same, same password, and it "should" have all just connected and never had a glitch. After 2 hours of weirdness, and trying to reset one of them, and get the TP Link to work.....I spent more time online and realized these are 2.4Ghz ONLY. I had set up the 5Ghz Wifi to be the original. I went in and made the 2.4G the old one, and BAM, everything worked FLAWLESSLY again. So, the 5Ghz wave I made the SSID-5G and all was right with the world once again, ha. My wife said this was silliness......she also said that when I got our first DVR 20 years ago......now the DVR is full of HGTV.....and she admits these things are great.

as a smart switch it works well. but it only works in a 3-way configuration. I thought I could use these 3-ways as 2-ways as well (obviously you can't do it the other way around), and I was hoping this would be a cheaper way to get a bunch of 2-way switches. but it doesn't work that way they can only be used as a pair in a 3-way setup. also there is no way to configure it to a 4-way and Kasa does not make 4-way switches.

I simply want to reiterate what others have said: the architecture of the Kasa 3 way switch is significantly different from other smart switch 3-way/4-way systems from traditional smart switch providers such as zWave, Insteon, Lutron, etc. Up until now, almost everyone else has required that you put switches in ALL locations in a 3-way or 4-way setup as they don't do traditional 3-way/4-way wiring but instead use the wires between switches for a non-standard, typically low voltage "carrier" signal that requires that all switches in a path be replaced with some sort of switch or other electronics. The Kasa architecture is far superior in that it participates in 3-way/4-way systems exactly the same way that traditional mechanical switches do, namely by operating as a single pole/double throw (SPDT) switch identically to either the switch at the power (line) end of the switching system or the lamp (load) end. So in a 3-way (two switch) or a 4-way (three or more swtiches) all you need to do is install the Kasa switch in one of the 3-way locations and it works in smart mode correctly, but all of the other traditional mechanical switches also still work as they previously did. You will know if you found one of the 4-way switches by mistake if it has 4 wires (ignoring neutral and ground) going to it instead of only 3. In that case you will need to find one of the 3-way switches and replace that one with the Kasa. I am in the process of replacing a lot of the smaller smart switch installations that use some of the traditional and older smart switches with Kasa, instead of growing them for multiple reasons: 1) as the Kasa switches often cost half or less than these other switches, it's often cheaper to simply convert everything to Kasa rather than grow these older systems 2) the Kasa switches talk WiFi instead of older wireless protocols such as zWave, Lutron, Insteon, etc. and if you do have good wifi wireless coverage I have found the Kasa wifi protocols to be more reliable, and doesn't require a hub which many of these others do and much simpler to setup. The Kasa app is also very elegant and functional and good not just for on/off operations but for basic automation as well. 3) Kasa has a wide range of products (switches, plugs, light adapters, etc) all very reasonably priced. The only missing piece IMHO is a 3 way dimmer switch, and TP-Link says that is forthcoming. I strongly recommend Kasa both for new smart home installations and also for extending existing ones by replacing older systems with a Kasa only installation.

I'm NOT an electrician. My electrical prowess is on par with someone who can accidentally cut clean through an extension cord with electric hedge trimmers, then break out the electrical tape and piecing the wires together to get it functioning again. The HS210 kit comes with 2 3-way switches that can be used in two separate “groups”. The switch that you are replacing HAS TO HAVE A NEUTRAL WIRE, not usually a problem for newer houses. If not, you can try looking at the other switch. If you are tackling this job, I can only assume you can follow the app and won’t burn down your house. The first switch that I upgraded was text book simple. I replaced both switches in a two-gang box to control two separate lights. Each switch had it’s own neutral wire and life was good. It was like putting together an IKEA table… there wasn’t much I could get wrong. The app is a great walk-through and makes an easy job easier, although, it will try and get you to use both of your smart switches to control one light. If you have read any of the other reviews, you know you only need one. Anyway, I move on to my second set of switch I want to replace… same scenario at a glance, but what lied beneath was vexing. When I took off the wall plate and labeled my wires, I noticed there was only one, what I assumed, group of neutral wires. After much time researching and a few incorrect wirings, I found out that if both switches go to a single fuse, you can use that neutral for both switches. The Kasa app works very well on my Android. In comparison to the Smart Life app, the Kasa app is much more reliable. The Kasa app controls my TP-Link brand switches/plugs and the Smart Life is used for my random smattering of no-name brand switches/plugs. The Kasa widget functions like it should while the Smart Life has a tendency to report switch status incorrectly and not toggle when I hit the button. The Kasa widget only has scenes that you can select where the Smart Life has individual switches/plugs. I don’t think I have had any issues with Google Home or Alexa controlling my TP-Link devices, but there have been issues where the Smart Life plugs don’t respond. Also when Google/Alexa are used to turn on Kasa scenes, it seems to work well, however the equivalent Smart Life Smart Scenes don’t seem work. Things I Learned From Install On a normal 2-way switch, the common wire is usually connected to a screw that is darker in color One neutral wire can be used for two switches if they are on the same fuse If you hook up a common wire to a TP-Link HS210 switch correctly, and what you thought was a neutral wire but actually another common wire, the switch glowing circle will light up briefly and then out. It only took twice for me to decide that I was doing something wrong. On the plus side, it didn’t burn out the switch or my house. Finally, if you have kids that are 3 inches way from the HS210 Smart Switch and are more than capable using the smart switch as an actual switch, they will inexplicably shout out to Alexa, who happens to be on the other side of the house, to turn off upstairs hallway lights.

I purchased this kit in addition to a single switch of the same model. I wanted to remotely control three separate light sets. One set consisted of a foyer light. The foyer light had a switch in the ground level foyer and a switch one level up in my townhouse. Another set consisted of a light in the hallway between the foyer and the recreation room to the back of the first level as well as a light above the stairs landing between the first and second floor. There are four switches that control those two lights. The third set consisted of a light above the stairs landing between the second and third floors as well as a light in the third floor hallway. There are three switches that control those two lights. I wasn’t sure if I should replace and connect the switches one at a time. Or, if I should replace them all while the power was off and then connect them to the Kasa App. I decided the latter was more convenient. I followed the instructions and found that one of the two switches for the foyer light had a neutral wire. I replaced that switch. Surprisingly, it wasn’t the switch located the closest to the fuse panel. Next, I began checking the four switches for the next set of lights. I had read reviews stating that this switch could be used in a four switch set. However, the manufacturer gives no approval or instructions for such a connection. Upon opening all four switches, I was unable to recognize the neutral wire in any of the switches. Two were clearly four way switches and two appeared to be three way switches. I considered that it was possible that a different colored wire was used for the neutral connection. For instance, I saw a red wire connected to white wires. Nevertheless, since I wasn’t sure and I feared a fire hazard if I improperly wired the switch, I decided not to add a switch to this set. I found a neutral wire in the third set of switches. This set had three switches and a neutral wire was found in one of the two switches on the third floor. I was expecting to find the neutral in the switch on the second floor that controlled the lights on this set, but I didn’t recognize the neutral in that switch. The point is, the neutral wire may not be where you expect to find it. Some reviews say you’ll find it nearest to the electric (fuse) panel or first or last in the chain of switches. That may not necessarily be the case. Once I got the two switches installed, I turned the power back on and followed the instructions to connect the switches to the Kasa App. The first switch connected relatively easily. However, I had to exit the setup once or twice and restart the setup to get it done. The second switch, which was further from my router, took three or four tries. On several occasions, it either did not show the Wi-Fi signal I wanted to use or it just wouldn’t connect. Ultimately, it finished the setup, and all is working properly. I would highly recommend these switches for light sets that have two or three switches. While you might be able to get it to work with a light set with four switches, don’t be surprised if it doesn’t. BTW, the switches work as expected with the Kasa App, including scheduling as well as with Alexa.

I ordered these switches after making the mistake of ordering a different brand that were a bit less expensive with a special package deal. Even though the other brand (TreatLife) was also well reviewed, I had nothing but issues with them and there was no tech support to speak of. I installed these switches and they are WONDERFUL. The 3-way switches have a mix of wire nut pigtails and screw terminals. The single pole switches are all wire nut connections. I prefer the screw terminals since they are cleaner and take up less space in the junction box. This is important since the switches are bigger than normal switches and real estate in the box can get very crowded. The only hit against Kasa is that the switches come with ZERO electrical documentation in the box. I didn't need it, but I can see how that would confuse some people. I believe that the installation instructions are all in the app, but that does not seem to be as handy as having them on paper. Not a big deal though. Hooking them up and replacing normal switches was a breeze. I did 3 different circuits in under 30 minutes. Two circuits were 3-way overhead lights and one was a single-pole switch for a ceiling fan. Pulled out the old switches, wired in these new smart switches and powered on the breaker. They worked on the first try. This should always be the case but I had the bad experience with the other brand where the 3-way switches did not work properly. It was very refreshing having these work so well. A few notes: 1) If you are installing the 3-way switches, you do NOT need to replace both switches on the circuit. That is why these switches need a neutral wire. It keeps them powered even when the lights are off, and thus act like any other 3-way switch. Just replace one of them. 2) You must have a neutral wire in the junction box. These switches will not work without a neutral wire. If you're not sure, remove the switch plate and look inside. If you can't tell, consult an electrician. Next step was to link with the Kasa app. I already had the Kasa app since I have an outdoor Kasa smart plug. I just went through the process of adding the switches and within 2 minutes the switch was connected to the Kasa app, Google Home, and Alexa. This was again in stark contrast to the TreatLife switches which did not connect well with WiFi. Kasa is a breeze and a joy to set up! Sure Kasa equipment may be a little more expensive than the other brands but they WORK and don't give me any headaches. That is worth the price. From now on it is all Kasa brand for me.

Three-way switches are kind of tricky. I was expecting a one-to-one swap with the existing wiring. I did a lot of research before attempting the swap. The instructions provided, describes "standard" wiring. On inspection, of the switch boxes, I was very confused. The electrician that recently did my kitchen wiring used scrap Romex utilizing existing black/white wires for the travellers. Neutral wire is needed for the Kasa switch was not connected to my old switch. Tips: 1) Take pics 2)Know how a 3-way switch works 3)Study the existing wiring and compare with instructions. 4)Proceed with caution! Make sure breaker to your switch is off. 5) After connecting/configuring, test each switch with app 6)Pushing wires back in box was really crowded. Careful not to short ground wires across any other terminals (electrical tape helps). Test one switch and re-test to make sure wires are still connected and not shorting.(If you have kids, make them wear ear plugs... ) 7) If you are still confused, the internet is your friend! 7)If there is ANY doubt, call a reliable electrician. I hope this helps. I am not an expert, just sharing my experience. The Kasa product itself, seems to work beautifully once you figure out the wiring. I would not want to attempt this again, unless it was absolutely necessary.
