Kasa Smart Dimmer Switch HS220, Single Pole, Needs Neutral Wire | 2.4GHz Wi-Fi Light Switch, Works with Alexa & Google Home, UL Certified, No Hub Required, White

🔌 The Core Function: Reliable Dimming After using the basic Kasa HS200 switches, I upgraded a few key areas—like the living room and master bedroom—with the Kasa Smart Dimmer Switch HS220. This switch is an immediate winner because it handles dimming with exceptional smoothness, even with my mixed bag of modern LED bulbs. The physical buttons on the switch make it easy to quickly adjust brightness, but the real power is in the app. ✨ Unmatched Customization (The App Advantage) The Kasa app truly unlocks the potential of the HS220 and sets it apart from simpler dimmers: Custom Fade: I love the ability to customize the "fade on" and "fade off" speed. I set my bedroom light to gently fade on over 3 seconds and fade off over 10 seconds, which is perfect for winding down at night. Flicker Control: You can use the app to calibrate the low-end dimming range for your specific bulbs. This eliminates the annoying flickering that often happens with smart dimmers set to their lowest levels, ensuring consistent performance. Scheduling: Setting lights to dim to 50% at 9 PM and turn off completely at 11 PM through scheduling is effortless and works flawlessly via Wi-Fi. 🛠️ Installation Notes & Reliability The installation process is similar to the HS200 and remains guided and straightforward through the Kasa app. However, two things are vital: Neutral Wire is Required: As with the on/off switch, the HS220 must have a neutral wire in the switch box to function. Be sure to check your wiring first! Bulkiness: The internal dimmer module is bulky. When installing it in a tight or shallow junction box, it requires careful management of the wires to fit the switch plate back on, which is the only real sticking point in the installation process. Once installed, the switch is highly reliable. It connects directly to the 2.4GHz Wi-Fi and responds instantly to voice commands via Alexa and Google Assistant, all without needing a separate smart hub. ⭐ Final Verdict The Kasa Smart Dimmer Switch HS220 offers features often reserved for more expensive systems, like fade customization and low-end calibration, at an incredibly competitive price. If you have a single-pole circuit that needs reliable, fully customizable smart dimming and you have a neutral wire, the HS220 is easily the best switch to buy.

The Kasa Smart Dimmer Switch HS220P3 does what it’s supposed to: it makes your lights smart and dimmable without fuss. Setup on 2.4 GHz Wi-Fi was straightforward through the app, and once it’s connected, voice control and scheduling work reliably. The dimming range feels smooth and consistent — no random flickering or dead zones like some cheap dimmers. Toggling through the app or voice is snappy, and automation features are actually useful. Here’s the practical reality: this switch requires a neutral wire. If your box doesn’t have one, you’ll need to run one or pick a different switch. That’s not a dealbreaker, but it’s something you absolutely need to check before buying — saves a headache halfway through install. Once installed correctly with a neutral, it’s solid. Responsive, easy to control, and integrates well with Alexa/Google Home. Just be sure your wiring situation matches what it needs; otherwise you’ll be picking up tools sooner than you’d like. Good smart dimmer overall — just not a drop-in for all houses because of the neutral requirement.

The light switch works just as advertised. Install was simple and just like any other light switch. If you have never installed one there are a lot of videos online. Connecting to wifi was also pretty easy. The best part is that it works with Alexa and we can now control our lights with the echo.

I recently installed a few WeMo switches so I could test them out, but found they weren't well designed and I wasn't particularly happy with them. So I started searching around for a new smart switch (Dimmer), and ran across the Kasa switches. I went ahead and purchased one to test it out. Installation: 5 stars, super easy and much better in my opinion than the WeMo switches. Main wires screw onto to the switch plate, and a couple of wires run off to attach with nuts. WeMo had all wires run off to attach with wire nuts which resulted in large amounts of wire and clutter behind the switches making them much harder to work with. Application: 5 stars, switch was immediately recognized and I had no problems with the application. Unlike the WeMo switches where I had several that had significant problems connecting, and they constantly disconnect. The Kasa switch has had a couple of times where the physical switch didn't work for a short period of time, but the app has always worked even when the switch didn't, and then the following day the physical switch would again work. Not sure if that is the result of a bad switch or if something else is going on, but ultimately it is a relatively minor issue as I can always use the application to turn the lights on or off if needed. Wireless: again the setup and connection were easy, and I haven't had any problems with the switch staying connected to my network and always being accessible via the application. I have loads of problems with this on the WeMo switches. Design: The design is much more well thought out from the wiring to even the physical function of the Switch than the WeMo version. WeMo uses a capacitive touch plate that runs the entire length of the switch. This results in the dimmer level constantly being change, turned off, etc... whenever you turn the light switch on or off because almost the entire switch is capacitive touch. Kasa on the other hand has their dimmer buttons at the very top of the switch so they are never in the way but are very easy to access. Quality: Quality seems to be on par with the WeMo, but the design decisions were clearly well thought out. If feels like someone actually tested the Kasa Switch, while it feels like no one actually ever tested the WeMo switch design of they would have easily seen and addressed several of the blatant issues it has. Note: there is one oddity with the Kasa switch, you may consider it a good or bad thing, but when turning the switch on/off there is a slightly delay (maybe 1-2 seconds). It caught me off guard at first and made me think the switch wasn't working properly. I'm still on the fence on whether this is a good thing or not, I think I prefer the instant switching action, but I can see why some people might prefer the delay and once you realize it is there it is honestly not a major issue. The Kasa Dimmer switch isn't perfect, there are a few oddities to it, but it generally functions well, it seems to be far more well thought out than the WeMo switches and is significantly more reliable as a "Smart" switch. If you are trying to decide between Kasa and WeMo, don't wait, go with the Kasa switches, they are significantly better in almost every way than my WeMo Switches have been. At some point I will be replacing the rest of my switches with the Kasa Switches and removing WeMo entirely from my house as they just have way too many problems with them.

Smartest upgrade to my house!! Never realized I could schedule a light switch via Google Home and WiFi. Super easy to install while the connectivity and compatibility is seemless. I bought several more over the years from my original purchase and my entire outside lighting of my home is fully automated to the sunset and sunrise. I have told many friends about this and they are impressed as well!

I installed the Kasa HS220 dimmer switch in our living room and it’s been a fantastic upgrade from a traditional switch. 💡 Smooth Dimming and Voice Control What really stands out is how smoothly it dims lights—either through the physical switch or remotely via the Kasa app. The responsiveness is excellent. It also integrates seamlessly with Alexa and Google Assistant (highlighted on page 1), letting you dim the lights with a simple voice command. 📱 Reliable App and Scheduling The Kasa app offers intuitive control and reliable scheduling. I love being able to set lights to dim gradually in the evening or simulate presence while I’m away (illustrated in the smart actions panel on page 3). The grouping feature also lets me control multiple Kasa devices from one dashboard. 🔧 Installation Was Straightforward Installation took about 15 minutes. Just make sure you have a neutral wire—this is clearly stated in the product title and specs (page 1 and 4). Once wired in, setup via the app was quick and painless. ✅ Pros: Works with Alexa and Google without a hub Reliable dimming performance and voice control Easy scheduling and scene automation via app Clear instructions and good build quality ❌ Cons: Requires a neutral wire Slightly bulky, may not fit well in tight electrical boxes Overall: This is one of the best smart switches I’ve used—sleek, responsive, and reliable. Great value for the price, especially if you're building out a smart home lighting setup.

Love it. Now my light switch is smart and I can control my lights with the Alexa and app. No more having to get up when forgetting to turn off the lights. Easy to wire up and connect. App is good and you cam fine tune the lights and even have them on a schedule too so they can automatically turn on/off at times of the day. The switch was compatible with all my led lights around the house after adjusting the high and low dim

Walkede through the process step by step easy peasy

Buenas noches, quiero comentarles que el día de hoy revisé mi correo y dice que el producto se entrego, en el cual quiero comentarles que no tengo el producto, hasta horita no he recibido el producto todavía, tuve comunicación con la paquetería en la cual se le indico que no podía recibir el producto ya que no me encontraba en Pachuca que regresaba hasta el lunes, por lo cual les pido de la manera más atenta rastreen al operador de la paquetería ya que no tengo ningún producto, gracias. Buenos días quiero ratificar que después de unos días de la fecha que se registró como entregado el paquete ¡llegó finalmente el producto! , lo revisé y venía cerrado y en buenas condiciones, lo conecte y probé y funciona de maravilla, la aplicación es muy sencilla y practica, lo recomiendo bastante, la relación precio producto es muy buena, gracias.

This is another great product from TP-Link. I am using their Smart WiFi Plug HS105 for the block heater with zero issues for three seasons already. HS220 comes with everything you need for installation but you absolutely need to check whether you have Neutral wire provided by your builder. If you don't adding it is pretty much impossible without reaping walls off. Seriously. I know a guy who sued his builder for failing to provide Neutral wire for lighting. First I would suggest to determine which wire is LINE and which is LOAD in your old light switch. I used multimeter for this purpose - you will always have 120ish volts between Line and Ground when the switch is OFF and nothing between LOAD and ground. Use Electric box as ground when you measure. I did have two LINE wires connected to the old mechanical switch - the second LINE was wired elsewhere and HS220 doesn't have any additional connectors for the second LINE. This is not an issue whatsoever - using pliers carefully make a half-loop for both LINE wires you have, completely unscrew the bolt (black in my case) on HS220 and remove small metal push plate. Lay both LINE wires the way so they wrap around the screw hole, put metal push plate back and tighten the black screw. Provided black screw is more than sufficient to tighten two 14G overlapped copper wires. Think strategically about all the wires you have in electric box since HS220 requires three times the space than you old switch. Locate all the wires in the box the way to allow enough space for the HS220 when you install it. Carefully push it in place applying pressure to the top and bottom flanges only (with Face Plate off, of course). Do NOT apply any pressure to the buttons while installing the switch. Do not panic if you don't get lights turning on fast enough with physical button or through the app. This is a well known issue which made people complain since December, 2020. This only happens because of double-tap functionality. Switch is making a delay checking whether single- or double-tap is used. Go to the TP-Link community website and download beta-firmware which works way better. Upgraded firmware from my PC and got ALMOST instantaneous switch response. The key word is almost since it doesn't look like you can get the same on/off performance from this switch as you do from a simple physical switch. Used the switch with cheap Sylvania 60W 2700K LEDs just for test. Will definitely go for brighter bulbs later. The only thing I REALLY don't like about this switch is annoying squeaking noise when on/off button is pressed. Makes entire unit feel really cheap. As per TP-link response this is working as intended and caused by the spring. UPDATE #1: Got two more switches and installed them the next day in two more rooms. Everything went smooth except of one switch with a somewhat crooked button which sticks and moves whenever the main button is pressed. There is definitely room for improvement in QC. Both switches are Hardware Version 3 and so far don't have any squeak. UPDATE #2: If you get dimmer switch wired on the same line as exhaust fan (I realized that one of my switches feeds exhaust fan in the nearby bathroom) you will get light blinking every time when the fan is turned off. Seems like this is the way all dimmer switches work. There is a solution suggested online involving the use of MOV (Metal Oxide Varistor) 270V (175VAC/225VDC) 6500A Surge Through Hole 20mm Disc. Need to try it and see if it works. UPDATE #3: Bought MOV through "Jameco Electronics" online. Just Google their web site. Ended up getting MOV-20D271K-ND equivalent. Installed it on the bathroom fan switch and IT WORKED!!! Now I do not have any more flickering caused by line noise or RF noise, generated by the switch connected to the induction motor opening (turning off). When bathroom fan wired on the same line with one of my HS220 is turned off I have zero flickering. Highly recommend this solution to those who are interested in fixing this annoyance.

This was the first set of smart switches that i purchased and it was honestly a very confusing endeavor. there are just too many of them out there and a lot of mixed reviews. I ended up buying these on sale and honestly i am quite impressed. They were easy to install, easy to integrate with Google Home, and the app is super easy to use. As soon as you find the device, the firmware gets installed and you're good to go. I've lost electricity twice since they've been installed (not due to the switches) and they have never lost connection to wi-fi. They auto connect and without wifi still function like a regular switch. highly recommend this brand

It’s designed for American homes which have a 110V supply. UK homes have a 230/240 V supply so it can’t be used in UK homes

Funciona de maravilla, compre un par para probar y después de un mes comencé a automatizar por completo la casa, en precio conviene mejor que comprar lámparas inteligentes. El único problema que veo es que no están diseñados para las cajas de conexión estándar en México, si caben pero es muy complicado acomodar los cables, por lo que deben considerar este factor antes de comprar, sobre todo si sus cajas de conexión son demasiado antiguas; resolví este problema perforando a un lado de las cajas existentes e instalando una caja mas grande que ya puedes encontar en el mercado.
