đ The Core Function: Reliable Dimming After using the basic Kasa HS200 switches, I upgraded a few key areasâlike the living room and master bedroomâwith 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. đ ď¸ 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. â 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 itâs 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 itâs connected, voice control and scheduling work reliably. The dimming range feels smooth and consistent â no random flickering or dead zones like some cheap dimmers. Toggling through the app or voice is snappy, and automation features are actually useful. Hereâs the practical reality: this switch requires a neutral wire. If your box doesnât have one, youâll need to run one or pick a different switch. Thatâs not a dealbreaker, but itâs something you absolutely need to check before buying â saves a headache halfway through install. Once installed correctly with a neutral, itâs solid. Responsive, easy to control, and integrates well with Alexa/Google Home. Just be sure your wiring situation matches what it needs; otherwise youâll be picking up tools sooner than youâd like. Good smart dimmer overall â just not a drop-in for all houses because of the neutral requirement.

I installed the Kasa HS220 dimmer switch in our living room and itâs been a fantastic upgrade from a traditional switch. đĄ Smooth Dimming and Voice Control What really stands out is how smoothly it dims lightsâeither 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. đą 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 Iâm away (illustrated in the smart actions panel on page 3). The grouping feature also lets me control multiple Kasa devices from one dashboard. đ§ Installation Was Straightforward Installation took about 15 minutes. Just make sure you have a neutral wireâthis is clearly stated in the product title and specs (page 1 and 4). Once wired in, setup via the app was quick and painless. â
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 â Cons: Requires a neutral wire Slightly bulky, may not fit well in tight electrical boxes Overall: This is one of the best smart switches Iâve usedâsleek, responsive, and reliable. Great value for the price, especially if you're building out a smart home lighting setup.

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.

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.

If you know how to install a regular switch, It's very easy to install. You Do need to connect 4 wires. Line, Load, Neutral and Ground. If you have never done it before, ask some professional electrician to install. If you live in an apartment, ask the landlord beforehand.
