Kasa smart switch

Kasa smart switch DEFAULT

People may take light switches for granted because they’re, well, pretty boring. (Not to us, though!) Smart switches, however, add a little pizzazz and convenience, letting you control your entire house’s lighting with an app or voice command whether you’re at the office, on vacation, or in bed for the night. We recommend the TP-Link Kasa Smart Wi-Fi Light Switch Dimmer HS220 because it’s easy to use, affordable enough for you to install several throughout a home, and designed to support Amazon Alexa, Google Assistant, and IFTTT.

The TP-Link Kasa Smart Wi-Fi Light Switch Dimmer HS220 connects directly to your home Wi-Fi network, includes three buttons (for dimming and on/off) plus a status light, and looks good on your wall. The app allows you to create automated schedules and to control groups of switches, as well as to program the dimmer to react based on how you touch it—so a long press or a double tap, for example, can instantly turn it on/off, instruct it to fade off, or tell it to go to a preferred preset dimming level. The HS220 also integrates with Amazon Alexa and Google Assistant, so you can tie lights to voice commands and other devices around the house. The one thing it can’t do is simulate occupancy via an Away Mode; for that feature, consider instead its non-dimming counterpart, the Kasa Smart Wi-Fi Light Switch HS200.

The Monoprice Stitch Smart In-Wall On/Off Light Switch With Dimmer also has built-in Wi-Fi and is a great alternative for people who want something reliable and inexpensive but don’t love the three-button layout of the Kasa Smart HS220 dimmer. We prefer the Kasa app and some of the additional features it offers, but the Stitch is easy to operate, allows for scheduling based on a variety of conditions (including weather), and works with Alexa, Google Assistant, and IFTTT. If you don’t need dimming capabilities, we also recommend the slightly less expensive Monoprice Stitch Smart In-Wall On/Off Light Switch.

If you already have a smart home that supports Z-Wave devices, choose the GE Enbrighten In-Wall Z-Wave Smart Dimmer. It requires the use of a Z-Wave smart-home hub and is compatible with many of the most popular hub models, including those from SmartThings, Ring, Wink, Vivint, Honeywell, and HomeSeer. It’s also the easiest-to-use, least expensive Z-Wave dimmer we tested, providing remote control, customized Scenes, and scheduled use so you can turn the lights on and off at set times of the day.

The Lutron Caséta Wireless In-Wall Smart Dimmer relies on a rock-solid network, a wireless system that is especially helpful if you have Wi-Fi dead spots in your home. The app lets you easily create Rooms, Zones, Scenes, and automated schedules, though it’s more expensive than our other picks and lacks the ability to remember the last used setting. What does make the Lutron Caséta dimmer a standout is that it doesn’t need a neutral wire, which is great for older homes, and it works with Amazon Alexa, Apple HomeKit, and Google Assistant, as well as SmartThings, Sonos, and many other popular smart-home systems. You will need Lutron’s Caséta Smart Bridge or a Wink Hub, which adds to the overall cost, but buying a starter kit is cheaper.

Everything we recommend

Why you should trust us

I first started testing smart-home devices back when the only smart-home devices were X10. Over the past 15 years, I’ve had my hands on everything from remotes and security cameras to AV receivers and smart bulbs. I’ve also written articles for The New York Times, Wired, Woman’s Day, Men’s Health, and USA Today, among others.

Although I performed hours of testing on each switch myself, my husband, who is a licensed electrician, completed each installation. He has installed literally thousands of switches and was able to help me evaluate each installation and the build quality of each switch; this also made swapping out switches 10 times faster than if I’d done it. If you aren’t comfortable or familiar with wiring, it’s always best to have a professional do it.

Who this is for

No one likes entering a dark house. Smart lighting allows you to turn lights on and off from almost anywhere using a smartphone, as well as to use an app to set timer-like schedules so your lights power on and off automatically based on the time of day, among other variables. There are a lot of smart-lighting options (such as bulbs and plug-in switches), but in-wall smart light switches are a more permanent fixture, allowing you to control one or more lights on a circuit.

Most smart switches are an easy swap (although you should hire an electrician if you aren’t comfortable with turning off the power and poking around inside the wall). And smart dimmers can help you save on your electricity bill because you’ll frequently set the light level at less than full blast.

Most wireless switches connect directly to your home Wi-Fi network, but some need a smart-home hub or proprietary network bridge that sets up a separate wireless network. In-wall wireless switches can control one or more lights at a time and typically can integrate with other smart devices, so you can have your lights triggered by motion sensors, smart locks, cameras, or even the sound of your voice.

One issue that comes up a lot when you’re using modern LED lighting and dimmers (smart or regular) is buzzing or flicker, which can be maddening—especially as these switches can be so pricey. We spoke with Brent Protzman, director of building science and standards development at Lutron, and he explained that LED bulbs can be much more prone to issues. “The behavior of the electronic driver inside the LED lamp is quick and directly responsive to the everyday fluctuations on a home’s electrical supply,” he said. “Some LED bulbs may also make an audible buzzing sound due to the vibration of its components, and the level of vibration (buzzing) depends on the LED design.” So if you experience buzzing with your new switches, before ripping out your switches (and hair), try swapping out the bulbs for a better fit, or vet the dimmer on the company website or with its tech support before buying to confirm that the dimmer is compatible with your bulb or fixture.

How we picked

A set of dimmers sitting on a small mat on a wooden countertop.

For years, we‘ve been keeping up with reviews and roundups of in-wall smart dimmers and switches. For us to consider a model for testing, it needs to be wireless and designed for installation inside the wall. All dimmers are also switches, and we favor dimmers because they’re better for setting a mood and saving electricity. We consider all the following features:

  • Dimming: If you have a dimmable light, you need a smart dimmer. One of these typically costs around $5 to $20 more than the standard in-wall smart switch.
  • Scheduling: All smart switches and dimmers offer scheduling so you can turn lights on and off at predetermined times of day. We consider it a bonus if any models offer scheduling based on sunrise and sunset and the status of other devices, as well as scheduling for every day of the week, or an Away Mode for security that simulates occupancy by turning lights on and off randomly.
  • Smart-home and voice integration: Most of the models on our list offer some type of voice control, with Amazon Alexa and Google Assistant being the standard. Some models can also tie in to Apple HomeKit or IFTTT (If This Then That), which lets you create your own smart-home rules, called “recipes.”
  • Wireless technology: Most of the smart switches and dimmers on our list use Wi-Fi, but we also consider models that use Z-Wave, Zigbee, and even proprietary wireless technologies.
  • More control options: Only a few companies are producing smart switches that work in three- and four-way configurations. If you need to control lights from multiple switch locations (for example, at the top and bottom of the stairs), ensure that you get switches only from those companies.

Prices for these switches vary widely, but the majority cost $20 to $100, with dimmers and Alexa-integrated models at the higher end of that range.

How we tested

My husband, a licensed electrician, installed each model. Some switches come with electrical leads attached; others have only terminals. Having leads should make the installation easier, depending on the size of your wall box.

The part of a wireless switch that goes inside the wall is bulkier than that of the average light switch, due to the extra technology built in. That doesn’t mean you’ll need to get out a handsaw, but it does make the installation slightly more difficult than your average light-switch swap. Except for two dimmers, each in-wall model we reviewed this round requires a neutral wire. If you have older switches, you may not have this wire inside the existing box. If that is the case, you must either buy a switch that doesn’t require a neutral wire or hire an electrician to rewire the entire switch configuration (you could also consider putting a completely wireless in-wall switch in that location).

Even with the larger switch body and the wiring requirements, my in-house electrician took only about 10 to 15 minutes to complete each installation, which included shutting off the electricity at the circuit breaker and removing the old switches.

We tested each switch separately for a minimum of two weeks (most of them much longer—some for years). All of them allow you to turn lights on and off remotely, as well as to set schedules using each device’s respective smartphone app. Dimmers add the option to trigger a connected light to dim at a certain time of day. All of the models we tested switched lights on and off without delay (except where noted in the Competition section), both when we physically touched the switch and when we used app controls.

To test remote functionality and features, we used apps on an iPhone 7, an iPad, and a Nokia 3.1 running Android 9 Pie. Aside from Siri, we also used an Amazon Echo Dot, Echo Plus, and Echo Show, as well as a Google Mini, for devices compatible with voice commands.

Security, privacy, and in-wall smart switches

Wirecutter takes security and privacy issues seriously and investigates as much as possible how the companies whose products we recommend deal with customer data. As part of our vetting process for smart outlets, we looked at all of the security and data-privacy practices behind our picks. We also reached out to all the companies that produced our top picks and had them answer an extensive questionnaire to confirm information that we thought should be of primary concern for any potential buyer. Here are the results.

Our pick: TP-Link Kasa Smart Wi-Fi Light Switch Dimmer HS220

A person's finger rests on the Kasa Smart Wi-Fi Light Switch Dimmer

After six months of long-term testing, we think the TP-Link Kasa Smart Wi-Fi Light Switch Dimmer HS220 is the best smart light dimmer. It’s reliable, easy to use, and affordable enough that you could reasonably install smart dimmers all over the house. The Kasa app is one of the friendliest we’ve tested, with clear controls for Presets, Schedules, and Timers. It also responded quickly in our tests, and it allows you to group a switch with other Kasa devices (such as smart plugs and smart bulbs) and to set up integration with Amazon Alexa, Google Assistant, and IFTTT.

The Kasa Smart HS220 is a standard single-pole dimmer (meaning it can control just one circuit from one location), and we found it dead simple to use—which is exactly what you want in a light switch. There’s no wondering what the buttons do, and no need to root around the iOS or Android app. The actual switch features three buttons: a large one for on/off and two small ones to adjust dimming.

Once you’ve pressed the switch, a thin strip of LEDs atop the dimming buttons briefly illuminates to show the dimming level; it then shuts off after a few seconds. When turned off, the HS220 has, in the center of the large button, a faint circular LED that’s bright enough to be visible in a dark room but not to keep you up at night. You can adjust dimming levels by going into the app or by calling out to Alexa or Google Assistant (“Alexa, dim the mud room to 25%”). The Kasa Smart HS220 remembers dimming levels, so if you turn off the light when it’s dimmed to 50%, for example, the next time you trigger it, the switch will turn on to the previous setting, unless you’ve scheduled it to do otherwise.

The Kasa app also allows for a level of customization we haven’t seen elsewhere at this price. It includes options to set dimming fade speeds for on and off, as well as how long you want that fade off to last (preset speeds vary from 10 seconds to five minutes, but you can also choose a custom time). Those controls are useful; you might, for example, want to hit the switch and exit a room without having to feel your way around in darkness. The app also gives you the option to program custom actions for the switch based on whether you tap the switch twice or do a long press, so it will go on/off instantly, fade off, or go to a preset dimming level. For instance, we set a double tap to turn the light on to 50% and a long press to fade it off after one full minute.

One thing we really loved was the Dimming Calibration feature (you can find it at the bottom of the Device Settings menu in the Kasa app). If you’ve ever dimmed lights using a smart switch and thought they didn’t seem dim enough, or if you’ve experienced flicker, this is how you fix it. Open the setting and drag your finger on the dimming strip to find the minimum level at which the bulbs will light up. Once you’ve got that, tap Test. The lights will then brighten from the lowest setting to the brightest. The process should be smooth, without any flickering. If you see flickering, you may need to adjust levels or, potentially, change the bulbs if they aren’t compatible.

TP-Link Smart Wi-Fi Light Switch HS200

We tested the HS220 at a variety of dimming levels, with both the Android and iOS apps, Amazon Alexa, and Google Assistant. We also grouped it with the Kasa Smart Wi-Fi Light Switch HS200, our previous budget pick, in an arrangement that let us turn on several lights with a single press in the app or a voice command. We also created an Alexa Routine to have the Kasa switch trigger whenever someone approached our Arlo Video Doorbell (our top doorbell pick), and we paired it with IFTTT to turn on whenever someone walked past a Wyze Cam v2 (our budget indoor camera pick). In all our tests, it worked flawlessly and reacted quickly.

Flaws but not dealbreakers

Kasa has confirmed that, confusingly, there are three versions of this dimmer model being sold by retailers, and some users have reported that one version creates a slight squeak when the rocker is physically operated. If you have this issue and are bothered by it, we recommend returning the dimmer to the retailer or reaching out directly to Kasa, which offers a two-year warranty.

The Kasa Smart HS220 supports up to 300 watts of power, while our other picks are able to support twice that. Why does that wattage matter? If you use low-wattage LED bulbs (a 75-watt equivalent draws around 10 watts) or lights with just two or three incandescent bulbs, it probably doesn’t matter, but if you hope to control multiple high-wattage lights using the same switch, you should confirm that it can support your needs.

Like many of the switches and dimmers on our list, the HS220 requires a neutral wire. That means installing it may be a problem in homes with old electrical wiring (houses built before 2011 weren’t required to have a neutral wire for switches). If you have an older house or aren’t sure if your wiring has a neutral, we recommend our upgrade pick, the Lutron Caséta Wireless In-Wall Smart Dimmer.

And finally, we’re disappointed that the HS220 doesn’t have an Away Mode, a setting that randomly turns your lights on and off during a set time to make it appear as if someone is home. For instance, if you’re going on vacation, you could set an Away Mode to trigger between 8:00 p.m. and midnight every night to turn the lights randomly on and off to mimic someone going in and out of a room. The cheaper and non-dimming HS200 has this feature, which makes the omission in the HS220 even more bizarre. However, you can add Away Mode to the HS220 via Alexa Guard.

Runner-up: Monoprice Stitch Smart In-Wall On/Off Light Switch With Dimmer

The Monoprice Stitch Smart In-Wall On/Off Light Switch With Dimmer

If our top pick is sold out or you prefer a traditional rocker-style switch, we recommend the single-pole Monoprice Stitch Smart In-Wall On/Off Light Switch With Dimmer. It also connects directly to Wi-Fi without the need for a hub, and it works with Amazon Alexa, Google Assistant, and IFTTT. The Stitch is easy to set up and control, but it doesn’t offer as much customization as the Kasa. Also, we encountered a few quirks with the app that pushed it just below our top pick.

The Stitch dimmer has one tiny blue LED on the bottom, which turns on or off along with the switch. (The LED’s light level isn’t adjustable, which we would have preferred, but at least it doesn’t flood a room with light.) To turn lights on and off at the switch, just push; a longer press adjusts dimming levels. Given this dimmer switch’s low price, we were very impressed by the build quality—this is one sturdy switch, and it delivers a really nice snap when pressed.

The Stitch app is no-frills, with on/off functionality available on the home page and under the main page for the dimmer. On that dimmer page, you’ll also find the Schedules option. The Smart tab at the bottom of the main page allows for Scenes and Automations, which let you schedule the dimmer based on set times, local sunrise/sunset, and even weather conditions. Although it doesn’t have an Away Mode, you can apply a workaround using Amazon Alexa; for instance, we were able to schedule the light to go on at sunset based on our location. Just know that for some of those Automations to work, you will need to grant access to your location.

Our one gripe with the app is that the scheduling feature only turns the switch on or off. To schedule the light to go on at specific dimming levels, you need to use the Automation field. On the same tab, you can also set timers, which can turn lights on and off after you leave the room. It’s good that both features are present, but considering how user-friendly this dimmer is otherwise, it just seems odd that they are on a separate page.

Unlike our top pick, the Stitch is a bit more no-frills. The switch offers no way to set it to do anything special, no customized fade times, and no dimming calibration. If those things don’t matter to you, and if you prefer a standard rocker, the Stitch dimmer is a reliable, affordable alternative to the Kasa Smart HS220. And if you don’t need dimming, the Monoprice Stitch Wireless Smart In-Wall On/Off Light Switch delivers the same features (except the dimming) for a few dollars less.

Also great: GE Enbrighten In-Wall Z-Wave Smart Dimmer

The GE Enbrighten In-Wall Z-Wave Smart Dimmer

The GE Enbrighten In-Wall Z-Wave Smart Dimmer is a great in-wall dimmer for anyone who already uses a Z-Wave smart-home hub such as a SmartThings, Ring, Wink, Vivint, Honeywell, or HomeSeer hub. Although many basic lighting features, such as dimming and scheduling, are standard across most hubs, it’s important to note that special features, including support for voice platforms like Alexa, Google Assistant, and Apple HomeKit, are contingent on the hub you use. Also, because GE does not have its own, proprietary hub, this dimmer won’t receive firmware updates. That means it won’t get new or improved features or security fixes should any be needed.

Like our runner-up from Monoprice, the GE Enbrighten is a sturdy, traditional rocker-style switch. The actual switch delivers a nice snap and allows you to dim the lighting with a long press. It also has a tiny blue LED on the bottom, which you can adjust to be always on, off, or contingent on the status of the switch.

We paired the GE dimmer with the SmartThings Hub and our Ring Alarm system. The dimmer performed well in our tests, reacting quickly to commands. Of course, your mileage may vary, depending on the hub you use. Speaking of which, depending on your hub, you can pair the GE dimmer with other smart-home devices, as well as create Scenes, so you can have one-touch access to your favorite dimming levels; for instance, we created a Dinner Scene that would turn the light on to 50%. You can do the same in Alexa or Google Assistant; using both, we frequently barked out orders to turn the switch on and change the dimming level, and the switch responded accordingly.

If you’re looking for more customization at the switch and don’t mind doing the tweaking yourself, the HomeSeer HD-WD200+ dimmer switch may be a better fit. The HomeSeer platform can pair with the SmartThings Hub, but it also has its own hub and a flash-based upgrade kit, allowing for firmware updates. However, we found the GE Enbrighten to be easier to set up and use, as well as more affordable.

Upgrade pick: Lutron Caséta Wireless In-Wall Smart Dimmer

A Lutron smart light switch shown installed in a wall.

After years of testing and use, we still think the Lutron Caséta Wireless In-Wall Smart Dimmer is a smart choice, as it provides remote on/off, dimming, scheduling, and grouping by room. It’s also the only one of our picks that works with Apple HomeKit, Amazon Alexa, and Google Assistant. And unlike most of the models we tested, this Lutron Caséta wireless dimmer doesn’t tap directly into your home’s Wi-Fi. Instead, it operates via Clear Connect, Lutron’s proprietary radio-frequency protocol. This setup boasts a more reliable connection because it doesn’t conflict with all of the Wi-Fi devices you may have around your house. However, it also needs the Lutron Caséta Smart Bridge, which connects to your router with an Ethernet cable and allows your smartphone to talk to the wall units. This arrangement costs more and might be a problem if you keep your router in an out-of-the-way place, because the Smart Bridge has to be within 30 feet of each dimmer to maintain a reliable connection. (If you have a larger home, a Lutron plug-in smart dimmer can act as an extender.) But several Wirecutter editors use this Caséta in-wall dimmer and report that they haven’t experienced any range problems.

Lutron sells a starter package containing the Smart Bridge, one dimmer, and one remote control, and we think it’s a bargain—it’s cheaper than some of the standalone switches we’ve tested. Lutron’s Caséta Smart Bridge is part of a larger lighting ecosystem that includes plug-in switches, wireless remotes (which can act like three-way dimmers or switches), and even wirelessly controlled window shades. The Smart Bridge also makes it possible for this in-wall dimmer to work with more smart devices and platforms than any other switch on our list, including Amazon Alexa, Apple HomeKit, Google Assistant, SmartThings, Sonos, IFTTT, and many other third-party devices. So although the Caséta setup needs the Smart Bridge, it does a lot with that.

The Lutron Caséta switch is one of two models we tested that don’t require a neutral wire. That makes installation a little easier, and it’s great if you have an older home or older switches, as many homes don’t have the extra wire inside their existing boxes. On top of that, the Caséta switch is the only one with a multi-button keypad: Instead of having a single rocker, slider, or button, this dimmer features four separate keys for you to turn lights on or off or to raise or lower brightness; those keys are slick and sturdy, they lie flat parallel to the wall (unlike a rocker switch), and they emit a nice little snap as you press each one. The Caséta switch also has a strip of LEDs along the side to indicate the brightness level.

Lutron’s app is easy to use, but turning the light on or off takes an extra tap. Everything else is clearly marked, so you can enable scheduling, geofencing, and the Smart Away feature, which can trigger lights randomly during a customizable window of time. Scenes are equally simple to set with a few taps, so you can group different devices as well as set dimming levels that you can turn on and off with one touch. And you may want to do that, since this switch doesn’t remember the last used setting; it goes on at full brightness every time you turn it on from the app or via voice commands. There are two workarounds for this. You can program the favorite button on the pico remote or create a Scene for that switch that sets it to your preferred dimming level (but we’d prefer not to have to do that for every switch).

What to look forward to

We plan to test the Eaton WFD30 Wi-Fi Smart Dimmer, a Wi-Fi–enabled light dimmer with Alexa support and the option for single-pole or three-way configurations.

Treatlife offers several inexpensive switch and dimmer options for single- and three-way configurations. We will soon have a review of the Treatlife Smart Dimmer Switch, a single-pole dimmer that works with Alexa and Google Assistant.

TP-Link plans to release two new smart dimmer switches sometime this year. The Kasa Smart WiFi Light Switch (KS230 KIT) is identical to our top pick, except it comes with two dimmers for a 3-way configuration, so you can control the same light from two different locations. The Kasa Smart Wi-Fi Dimmer (KS220M) is a single-pole model that includes motion detection and an ambient light sensor for completely touch-free control.

The competition

The Leviton Decora Smart Wi-Fi 600W Dimmer DW6HD is typically more expensive than some of our picks, but it includes single-pole and three-way functionality plus remote on/off, dimming, and scheduling that works well. Like other models, the DW6HD provides customizable Scenes, scheduling, and fade rates, with support for Amazon Alexa, Google Assistant, and IFTTT. If you’re looking for HomeKit support, the DH6HD dimmer is sold separately, but it lacks Alexa and Google Assistant compatibility.

We found the HomeSeer HS-WD200+ to be best suited for smart-home enthusiasts who love to tweak. Setting it up takes more time and money than setting up our Z-Wave pick, although it does offer a lot in return, including the ability to program multi-tap functions at the switch and adjust the LED colors. And if you’re willing to spend the additional money on the HomeSeer Hub, you will receive firmware updates.

The Geeni Tap+Dim is almost identical to our Monoprice Stitch runner-up, which shouldn’t be surprising since the two use the same app developer. It functions well, but we thought it felt a little cheap and not as sturdy as any of our top picks.

The Legrand Tru-Universal Wi-Fi Enabled Dimmer is expensive and a bit trickier to work with than other models we tested due to a required QR code (which is on a little sticker affixed to the front—better hang on to that), a slightly larger (1.77 inches total) depth, and longer wires that crowd the switch box.

The C by GE Smart Switch Motion Sensing + Dimmer is pretty, but we can’t recommend it. This model is interesting because it’s one of the few switches we’ve tested that don’t require a neutral. However, in our tests it constantly asked us to connect to Bluetooth and had a handful of connection issues, and we found the app more confusing than it needed to be.

The Etekcity Smart WiFi Light Switch is easy to operate, with scheduling, an Away Mode, support for Alexa and Google Assistant, and the option to turn off all indicator lights. However, during our testing, the touch-sensitive button on the front sometimes wouldn’t respond to the first touch. Also, the device made a loud click when we flipped it on and off, whether we did so by touch, through the app, or via voice commands.

Providing single-pole, three-way, and four-way functionality, the iDevices Wall Switch includes a night-light feature that you can turn off or tweak to show a variety of colors using the company’s iOS or Android app, as well as HomeKit. However, it’s very expensive for a non-dimming smart switch.

The multi-way Insteon Dimmer Switch uses Insteon, a mesh of electrical wires and wireless RF technology. If you already have the Insteon hub, this switch is a no-brainer, providing reliable remote control, schedules, and dimming. Otherwise, we recommend going with one of our picks.

The Eve Light Switch is iOS-only and uses HomeKit, so you’ll need an Apple TV, HomePod, or iPad at home for control outside of the house. During testing, we had a few connection issues, but the real dealbreaker was that the response time was mixed, with the switch sometimes turning on and off quickly and other times taking a few seconds, whether we used the app or the touch-sensitive switch.

We had problems with the Aqara Smart Wall Switch, which pairs with the Zigbee-based Aqara Hub. We are working with the company and are continuing to test the switch, and we will report back when we have more thoroughly tested it.

We have yet to find a switch with Alexa built in that works successfully—and we’ve reviewed three of them to date. The Leviton Decora Smart Wi-Fi Voice Dimmer had problems with Alexa often failing to recognize commands, as well as frequent connection issues. The iDevices Instinct doesn’t dim, feels a little cheap for the money, and doesn’t use the same app as other iDevices products. And the Ecobee Switch+ also doesn’t dim, is overpriced, and was often buggy during our testing.

I find the TP-Link smart switches are a must-have gadget in your smart home with their sleek design, easy installation, and use, as far as smart switches go.

I’ve been using it for the past few months which I bought along with my 5GHz smart plug.

I love the TP-Link smart switch because it is compatible with other smart network hubs like Amazon Alexa, Google Home, SmartThings, etc.

In fact, recently, I made it work with HomeKit too.  

However, I found that it is common for these smart switches to malfunction from time to time.

I faced this issue in the past few days. That’s when I researched methods to troubleshoot my TP-Link HS200 with tech support.

How To Troubleshoot TP-Link Smart Switches

  • Check the wiringto your TP-Link smart switches.
  • Check the WiFi connectivityto your smart switch.
  • Reset and restart the your TP Link smart switch.  

Let’s explore why certain technical issues arise with the TP-Link smart switch and see what troubleshooting measures you can take to fix these issues.

Guide to Troubleshooting TP Link Smart Switch

There are many different issues that users have reported with their TP-Link switches.

However, for almost all of these technical problems, there are four simple solutions that you can try at home, by yourself.

Faulty Wiring to your TP Link Smart Switch

Faulty wiring or loose connections are some of the most common issues seen with the TP-Link HS200.

This issue can mostly happen when you’ve self-installed the smart switch. You might’ve ended up connecting to the wrong wire.

Also, check for the possibility that wires are not connected tightly and securely with each other.

This can even cause a short circuit within the device.

TP-Link provides the smart switches with color-coded wires to differentiate between live, neutral, and ground to avoid these issues.

They also provide wire caps that you can use to connect the wires securely. If you are inexperienced with electric circuits and wiring, refrain from installing the device yourself and hire a certified electrician instead.

WiFi Connectivity on Your TP Link Smart Switch

The WiFi LED light on your TP-Link switch can tell you about your device’s connectivity status to the network.

A static, solid green light means it is connected to your WiFi network. If it is blinking amber and green, it means your device has been disconnected from the WiFi and needs to be reconnected. 

To reconnect to the WiFi, try going through the setup process again in the Kasa Smart app.

If that doesn’t work, it means the signal is too weak to reach your TP-Link smart switch.

In that case, you might want to try moving your router closer to the switch, or if that is not possible, try using a WiFi extender.

It is important to note that the TP-Link smart switches are compatible only with the 2.4 GHz band of your WiFi network.

While it can still manage on the 5 GHz band or cellular data, it is recommended that the smart switch stay connected to the 2.4 GHz band of the main router.

You may also want to consider using a different channel on your WiFi network to avoid congestion when connecting your smart switch.

If a particular channel has many devices connected to it, it can slow down the network speeds over that channel, which could be why your smart switch cannot connect to the network.

If your smart switch is still struggling to establish a WiFi connection despite trying these solutions, try rebooting your router.

If there is an issue arising from the router, troubleshoot it to resolve the problem.

Reset And Restart Your TP Link Smart Switch

For a lot of WiFi devices, resetting or rebooting the device is a go-to solution.

Similarly, you can try to restart or reboot your TP-Link smart switch by following these steps:

  • Remove the front panel of the smart switch to reveal the reset and restart buttons.
  • Both the buttons are located right below the main power button. The one on the left is the reset button, and the one on the right is the restart button.
  • To restart your TP-Link switch, press the restart button just once.
  • To reset your switch, press and hold the reset button for five seconds. The WiFi light will begin to blink amber and green. This means your smart switch has been successfully reset and is now ready for use.

This reset is a soft reset, which means that the device will still have your settings and configurations intact, unlike a factory reset.

In all cases, a reset or reboot wipes away the current state of software that the device is running, thus eliminating any code that is stuck or misbehaving.

Factory Reset Your TP Link Smart Switch

Performing a factory reset on your TP-Link switch is very similar to performing a soft reset.

Instead of holding the reset button for five seconds, hold it for ten seconds until the WiFi LED begins to blink amber and green rapidly.

Once this happens, it means your smart switch is successfully reset to its factory defaults.

Factory reset removes all previous settings and configurations. Your TP-Link smart switch is now equivalent to a brand new device fresh out of the box and needs to undergo the whole setup and installation process from the beginning.

Other Solutions To Try If Your Smart Switch Is Not Working Properly

The four solutions mentioned above should fix most of the technical issues that arise with the switch in general.

However, there is another solution to try.

New firmware updates often fix existing bugs and add new features to the device.

This is why it is important to keep your firmware up to date. You can try updating the switch’s firmware via the Kasa Smart App by following these steps:

  • Click the icon on the top left to open the side menu bar. Click on “Settings”.
  • Under this menu, you will find an option saying “Firmware Update”. Click on it.
  • If there are any firmware updates available for your device, they will show up here.


Almost all technical issues with your TP-Link switch can be solved by trying out these methods.

The most common issue I have had with my TP-Link HS200 is the WiFi connectivity issue.

However, I solved it by rebooting the router and the device itself. 

If none of these solutions works, you can reach out to TP-Link’s customer support via their technical support email, asking a question on the community forum, or calling the toll-free number.

The average response time is less than 24 hours, and customer support is very reliable.

Frequently Asked Questions

How do I reset my HS200?

There are two reset options available to the TP-Link HS200. A soft reset keeps the current configuration.

On the other hand, a factory reset erases all custom configurations and resets the device back to factory defaults.

To cause a soft reset, press and hold the reset button for about 5 seconds until the WiFi LED flashes amber and then green to initiate the app configuration.

To reset the device to factory defaults, press and hold the reset button until the WiFi LED flashes amber rapidly.

What do the lights mean on the TP-Link extender?

The color or number of Signal LED lights on your TP-Link extender is indicative of the signal strength it is receiving from your main router. 

Solid green indicates that the signal is strong and that the extender is in an optimal location, while red indicates that the signal is weak and the extender needs to be moved closer to the router.

Where is the reset button on the Kasa Smart Switch?

The reset and restart buttons are located right below the on/off button, which is the rectangle’s bottom half.

The button on the left is the reset button, while the button on the right is the restart button.

How do I reconnect my TP-Link Smart Switch?

To reconnect your TP-Link Smart Switch, follow the same procedure you used to install it for the first time.

Connect your phone to the smart switch’s WiFi network, open up the Kasa Smart app, select your device model and proceed with the installation.

How do I connect to TP-Link?

Connecting to TP-Link smart devices is quite simple. First, make sure that you have the device wired and installed correctly.

Then connect your smartphone to the device’s WiFi network to begin setting it up.

Open up the Kasa Smart app on your smartphone, locate the model of the device you wish to set up, and follow the instructions on the screen to complete the setup.

Switch kasa smart

This 3 pack of TP-Link Kasa smart switches is under $30

Smarten up three light switches at an excellent price today. Amazon is selling a three-pack of TP-Link single pole Kasa smart light switches for $29.59, down from the current all-time low of $37. To get the sale price you have to click the 20 percent off coupon under the price on the product page.

The great thing about Kasa TP-Link smart switches is that they connect directly to your home network instead of going through a hub. It all happens via the Kasa smartphone app, where you can also set schedules, control smart devices remotely, and so on. Kasa gear can also integrate with Google Assistant and Amazon’s Alexa.

As these are single-pole switches you can’t use them on three- or four-way switches where you control a single light from multiple spots. These are solely for single location switches, and they require a neutral wire for installation.

Controlling three switches via your smartphone or smart speaker is a fantastic deal for less than $30. The one downside of Kasa gear is that if there’s ever a power outage then you’ll likely have to reconnect them to your network, but that should be a minor concern for most people.

[Today’s deal: TP-Link Kasa smart switches 3-pack for $29.59 with coupon on Amazon.]
