Kasa Smart Light Switch, Single Pole, Need Neutral Wire, HS200-BL

I bought this to control lights in a detached garage remotely, so that if I noticed they'd been left on I could turn them off without leaving the house. The instructions are pretty clear, and it doesn't take an electrical engineering degree to install--just make sure to flip the breaker first. The switch is bright white, and the included cover plate clicks right on. The switch worked perfectly right out of the box to turn the lights on and off manually, but I ran into difficulty connecting it via the app. I used Amazon's product page to get help, and one option was for them to call me, which they did right away, even on a Saturday late afternoon. Christian (who called) was very nice and gave clear directions (but also didn't treat me like an idiot, as sometimes happens with tech support). He troubleshooted as we went, working patiently through a couple of problems to figure out what was wrong. He knew specifics for the needed settings on my cell phone model, and we got it connected in less than 20 minutes. (Kasa: I don't know what you're paying him, but he's worth every penny--give him a raise!) Once the switch was connected to our house wifi, Amazon's Alexa recognized it without promoting, and I was able to use voice control and also set up a routine to turn it off at bedtime automatically. We have several Kasa products now, and the others have been working seamlessly for several years. Recommend!

I made the jump to a "Smart Home" a little over a month ago after Alexa joined our family. After talking to some friends, doing some research and assesing my needs I settled on TP-Link because of the variety of Smart products they offered, no requirements for a Hub, the lower cost and the ability to control everything from one simple app on my Smart phone and Amazon"s Alexa. I have not been disappointed. After a very short learning curve, I surprisingly found the installation and set-up of all the TP-Link Smart devices extremely easy and intuitive. I have installed several different Smart devices including three different bulbs (LB-100, 120 & 130) depending on the area, as well as, Smart Switches (HB-200) and Smart Plugs. All of it has installed, programed and worked with few problems. The only criticism I have is the Kasa App. I have found it to be a bit bugy at times, but since I use it primarily for programming and setting up new devices and scenes, rather than operationally, it has not been an issue since Alexa handels most of that work. So far, in the six weeks my Smart Home has been in operation I have only had one problem where Alexa and the Kasa app lost communication with most of (but not all) of my TP-Link devices. But after a bit of head scratching I was able to restore communication. So here's a tip to remember: I first tried rebooting the devices by cycling the power breaker, but that didn't work. Probably due to multiple devices signaling simultaneously and overloading Kasa. But, powering each device down for a few seconds then back up, and testing it before moving on ro the next one worked without a problem. I also recommend using a different control application. I only have experience with Amazon Alexa, but it also interfaces with Google Home among others. I have found that controlling scenes from Kasa not to be reluable for some reason, while issuing the scene commands to Alexa works 90% of the time, with repeating the command becoming necessary about 10% of the time. But even with an occasional repeated command being necessary, TP-Link devices respond extremely well through Alexa's control. Plus Alexa is able to easily "group" multiple devices so you can control areas with a single command, or program macro activities that Alexa can perform with a single command. Capabilities Kasa does not have. This is another deficiency of the Kasa app. Without the ability to group devices or run macro routines, it relies on programmed scenes which are very limiting for operational control. So another controlling app like Alexa or Home is essential to the TP-Link Smart Home system. For me, because I have Alexa for operational control, both at home and away, these short comings in the Kasa app are non-issues. But if I didnt have this capability I think I would look to a different Hub controlled platform for my Smart Home lighting and device control. HS-200 Smart Switch: I am a retired electrician, so I found the installation easy. Most DIY homeowners with a basic knowledge of electricity and components should also have few problems with the installation. I found this Smart Switch easy to control and the installation is about the same as replacing a standard light switch. But, a big drawback is not have a dimming capability. To me this should be a no-brainer and i cant understand why this featire is lacking. Because that would makevthis a 5 star product. So before you procede there are a couple of precautions that should be noted. First, you must three wires plus the ground (usually bare or green), and one must be the neutral (usually white) third wire, or the switch simply will not work. This can be an issue in some older homes (and even in some newer ones too). The neutral wire is the "common" wire that runs throughout the house and is common to all circuits. It completes the loop in the circuit from the electrical box to the receptacle. The "hot" (or "line") wire (usually black) carries the electrical load for that circuit only (usually 15-20 amps max). And finally, the "load" wire (usually black, red, or it could even be white) completes the hot side of the circuit between the switch and the receptacle. To save time and money some electricians when wiring homes "old school" would complete the light circuit by running the neutral to the light receptacle and then run a 2 conductor (plus ground) to the switch. So even though you may have a white and black wire at the switch, the white wire is not a neutral, but the load wire that that completes the hot circuit when the switch is turned on (closed). So if you don't have 3 wires, one of them being the white neutral, you are out of luck using a Smart Switch. You can control the light however, by using Smart bulbs and then grouping them in the controling app (like Alexa). Another caution is wire management. Standard light switches don't take up much room, so the original installing electrician had lots of room in the box to stuff extra wire. This is a luxury you don't have since the Smart Switch is much deeper and takes up most of the box. The new switch also uses leads that are wire nutted to the circuit wires and not terminated on the switch itself. Because of this, it may be necessay to shorten the wires to make room in the box for the extra electronics and wire nuts. My advice is to open your intended switch boxes to survey your electrical wiring BEFORE you order the switches, so there are no surprises when it comes time to install. One last safety precaution. Be sure to turn off the circuit at the electrical panel (breaker box). Also don't assume that all switches in a multi-switch box are on the same circuit. It is often the case that multiple circuits are in the box. This is especially true when a switch is controling a plug. So check all wires in the box with a meter to insure nothing is hot. Finally, when wire nutting multiple wires it is VERY EASY to leave a wire loose. This can be very dangerous, as loose wires can work themselves free and cause arking and sparking that can damage connected equipment, and worse, start a fire. This is a common cause of electrical fires, and you might not know there is a problem until it's too late. So to ensure all wire nut connections are tight and secure, tug on each wire at the nut with needle nose pliers. If you can't pull it loose it should be good to go. Also make sure there are no bare wires poking out of the nuts. The switches use stranded wire so it's easy to have some stray strands loose outside the nut. So that's about it. The install is pretty easy most of the time, but if you don't think you're experienced enough to do the job safely, put this phase of the job in the hands of a professional. It should be an easy job for any professional electrician, and should not be terribly expensive. Consider it cheep insurance!

Okay, let's craft a detailed review for the Kasa Smart Light Switch HS200-BL, assuming a positive experience for this example. Overall Rating: 5 out of 5 stars (based on the image and assumed positive experience) Headline: Effortless Smart Lighting Upgrade - Works Perfectly! What's most important to know? This Kasa Smart Light Switch is a fantastic way to easily upgrade your home lighting to be controllable from your phone, voice assistants, and schedules. Note: It requires a neutral wire connection. Make sure you check your wiring before purchasing. Add a photo or video: (Imagine a photo here showing the installed switch seamlessly blending with the existing wall plate. Maybe a shot of the phone app controlling the light, or a video demonstrating voice control via Alexa or Google Assistant.) Written Review: I recently decided to dive into smart home technology, and the Kasa Smart Light Switch HS200-BL was the perfect place to start. I was initially a bit intimidated by the installation, but it turned out to be surprisingly straightforward. What I liked: Easy Installation (with Neutral Wire): While the neutral wire requirement is crucial, assuming you have it, the installation was much simpler than I anticipated. The instructions were clear and easy to follow. I felt confident and safe doing it myself. Seamless App Integration: The Kasa app is intuitive and user-friendly. Setting up the switch and connecting it to my Wi-Fi network was a breeze. I love how easily I can control the light from anywhere. Voice Control Perfection: Integrating with my Amazon Alexa was incredibly simple. Now I can just say, "Alexa, turn on the living room light," and it works flawlessly. This is a game-changer for convenience. Scheduling and Automation: Being able to set schedules for the light is a huge plus. I have it set to turn on automatically at sunset and off when I leave for work. It adds a level of automation and security I really appreciate. Reliable Performance: The switch has been working flawlessly since I installed it. No connectivity issues, no glitches, just consistent and reliable performance. Affordable Price: Compared to some other smart lighting solutions, the Kasa Smart Switch offers excellent value for the price. What could be improved: Neutral Wire: While the description mentions the neutral wire, perhaps making this requirement even more prominent in the product title or bullet points would be helpful for those less familiar with electrical wiring. Also, it would be great if they made the same switch that deosnt require a neutral wire Physical Button Feel: The physical button on the switch feels a little different than a traditional toggle switch. It's a minor thing, but it takes a little getting used to.

I am really impressed with this Kasa smart switch. The installation process was incredibly straightforward and easy to follow, especially with the clear instructions provided in the app. Just make sure you have a neutral wire handy! Once wired up, connecting it to my 2.4GHz Wi-Fi network was seamless, and it integrated perfectly with Google Home right away. It's highly responsive, looks clean on the wall, and works flawlessly for scheduling and voice controls without needing an extra hub. It’s an absolute game-changer for upgrading to a smart home setup. Highly recommend!

My whole house is loaded with KASA products...smart bulbs, smart switches, led strips etc. One thing I had not upgraded was my porch light switch, mainly because I already had a programmable switch in the circuit. Unfortunately, that switch was programmed at the unit with a teeny tiny buttons and digital display. I don't like the porch light on all night, so I have to reprogram the light as the sunset times change. In Washington State that can be anywhere from 430pm to almost 10pm. Programing the old switch was a pain because of that and it did not recognize the yearly time changes. I bought the Kasa switch so I can do everything through the app. The installation was easy, especially since my wiring was labeled with "load" etc. The switch fit in a double gang box just fine and it worked with my existing faceplate. Now, my porch light cycles on and off when I want it too. If you want your porch light on sunset to sunrise, Kasa has that setting also. The app automatically adjusts to time changes. The only reason I did not give the switch five stars is it seems a little light duty. I never touch my switch, so it does not matter. If you have an "analog" person in your house who just HAS to flip switches on manually, I am not sure how long it the switch would last. Really, that should not be an issue because the whole reason to automate your home is so you do not have to flip random switches. KASA is great. You can do everything from your phone or tablet. KASA with Alexa is even better. You don't have to reach for your device in the dark...just say "Alexa, turn on bedside lamp." It is just that easy. Leaving to go on a trip? You can schedule your lights to mimic when they go on and off when you are home....fake out those would be thieves. Everything can be done seamlessly through the Kasa App. I highly recommend KASA products. Automate your home....DO IT NOW! Add an Alexa, Google Home or IFTTT control unit and enter whole new world.

I’ve installed multiple Kasa HS200 smart switches throughout my home, and they’ve quickly become one of my favorite smart home upgrades. 🧠 Works with Alexa and Google Assistant — No Hub Needed What I love most is the simplicity—this switch connects directly to 2.4GHz Wi-Fi without needing a hub (highlighted in the title and comparison chart on page 4). Once installed, it syncs seamlessly with Alexa or Google Assistant for voice commands like “turn off the kitchen lights.” 🔧 Straightforward Installation (If You Have a Neutral Wire) The product clearly states it requires a neutral wire (see "About this item" on page 1 and install guide on page 3), and that’s the only catch. Once you’ve got that, setup takes about 15–30 minutes with just basic tools. The Kasa app walks you through each step. 📱 Reliable App Control and Smart Features The Kasa app gives me full control over lighting from anywhere. Features like “Away Mode,” grouping, and scheduled routines (shown clearly in visuals on page 3) add a lot of convenience and security. ✅ Pros: No hub required, works over 2.4GHz Wi-Fi Alexa/Google Assistant compatibility Intuitive app with scene, timer, and away mode features Responsive and consistent operation ❌ Cons: Requires a neutral wire Slight learning curve if you’ve never installed a switch before Overall: This is a fantastic entry-level smart switch. It's dependable, integrates well with other Kasa devices, and is priced affordably. Highly recommended for anyone modernizing their home’s lighting without the hassle of a hub.

Very impressed with this smart light switch. Installation was simple and took only a few minutes, and the setup in the app was just as easy. It responds quickly, works flawlessly, and looks great on the wall. Definitely a solid upgrade for any home.

I was worry at first since my dad tried to install a motion sensor switch awhile ago at the washer room connect to garage. It did not work somehow. This time I pulled the trigger and tried it myself. After asking AI with pictures and watch youtube videos, it seems doable. And it did. Simple than I thought at first. However, don’t be alarmed if after you install and turn the breaker on, the switch flashing red (maybe orange, I can’t tell the difference). Just push the reset button locate just below the switch on the left facing you. The connection will take roughly few minutes like it stated on the app. This light switch can be control on Kasa App or TP link Tapo app as well. Remember to connect to 2.4Ghz wifi or the app will not connect to the switch. 10 out of 10 for Tapo, Kasa smart devices

Justo lo que necesitaba, tengo un anuncio de publicidad y necesitaba prenderlo y apagarlo a ciertas horas. Con esto ya lo tengo programado y me olvido de ello. Excelente calidad, dice que es fácil de instalar y si, siempre y cuando tengas la "fase" y el "neutro" donde lo piensa uno colocar, en mi caso no fue así, por lo que tuve que llamar a un eléctrico. Desgraciadamente donde lo tuve que poner es en el extremo de mi casa, llega el Wifi y lo conecté sin problemas, pero se me desconecta de vez en cuando (la señal no es de lo mejor en ese punto), eso si, la programación que le puse para prender y apagar no deja de funcionar. Y la reconexión es fácil, basta con oprimir el pequeño (casi imperceptible) botón izquierdo en la parte inferior del switch y hace la reconexión automáticamente. Muy recomendado, lo agarré con una buena oferta.

Amazing switch can be completed controlled by your phone.

Like the TP-Link Smart Plugs I already own this was simple to set up and works slick. TL;DR – Simple to use and rock solid performance, use the app anywhere, better than any timer from the hardware store. Look in the Apple and Google app stores for the “KASA” app. I’ve used both and they simply work without any tweaking. To use KASA you will need to create an account if you want to use the app remotely, no need if you only want to use it within your Wi-Fi range. You can do this right through the app. If your already using Amazons Alexa you’ll be happy to know that this device can be controlled through Alexa. A nice feature. When switched off there's a muted white LED that’s visible in the dark. The switch has three buttons, the big main light switch and two smaller buttons located directly beneath. To turn on the switch manually, depress and release the big switch which looks just like a standard light switch. It also fits into a standard single switch electrical box, it will also work in a dual or triple switch box as a standard modern cover plate made for the wide rocker type switches will fit perfectly over the portion around the main switch. I had looked at some of the non Wi-Fi options, the light switches that use a proprietary remote that's similar to what you would use with a TV but they all have limited range, maybe 30 meters if you’re lucky. The TP-Link system using the KASA app allows me to control these smart devices from around the house or when traveling through another province or country. Once you have connectivity to the internet it doesn't matter where you are, you can control these devices. One aspect that really appeals to me is the ability to set up schedules for the devices to turn on and off. If you already use timers to turn on lights while your away you'll appreciate that the app allows you to do that plus configure (this part isn't techy) the lights to come on randomly between certain hours which really makes it appear that someone is in the home. You can set up several schedules if you like. Any burglar with at least three grey cells knows to watch a home for a few days to see if there is a repeated sequence when lights come on. Once they discover the routine its actually the green light they need, they now know no one is at home since very few people always turn on the lights in certain rooms at the same time every night. This ability to set random schedules is a big bonus and really makes it appear that someone is in the home. There's one thing you should know here, this is not like the smart plugs when it comes to installation. Those you simply plug into the AC outlet and then plug in whatever it is you want to turn on remotely. This device completely replaces a wall switch which means you need to wire it correctly so I strongly suggest you hire an electrician or someone who has the skills to handle this if you aren’t qualified. Once the switch is installed the setup and connectivity portion is easy, it’s all done through the app and by pressing the little button to the left side (Reset) beneath the main switch. Again, this part is non-technical, simply follow the steps outlined in the very easy to follow instruction sheet which walks you through the 3 minute process. After that it’s easier to set up schedules and other features than entering a friends contact info in your phone. Comes with all the hardware needed to install in a standard electrical box including wire nuts Marretts).

Limpio, elegante y súper fácil de configurar. Después de configurar en la app Kasa pude agregarlos sin problema a la app Deco para controlar todo desde una sola app.

A simple switch to install and configure. Works with perfectly Alexa and also with Home Assistant as well as the native app. I do have one that occasionally goes offline - there are a couple of little buttons under the switch and pressing one of these brings it back online. Five others work perfectly. These are a bit bulky and the single challenge I had during installation was getting one of them into a rather crowded electrical box (I eventually shoehorned it in). Also, be sure there is a neutral in the box before buying. Quite a lot of switch boxes don't have a neutral wire as it was not require by code until quite recently.
