Customers say
Customers find the smart dimmer plug works well with incandescent holiday lights and is easy to set up, particularly noting it’s simple to add to existing Kasa home networks. Moreover, the device is heavy-duty and performs well outdoors, with one customer reporting it lasted all winter without issues. Customers appreciate its dimming capabilities, working with both incandescent and LED bulbs, and its user-friendly app control. Additionally, the timer feature receives positive feedback, with customers noting they can schedule times for on or off. However, connectivity experiences are mixed, with some reporting quick Eero WiFi system connections while others experience frequent disconnections.

Easy setup. Great app. Working well.
Purchased almost a year ago and works perfectly with my outdoor Feit LED stringlights. Great Kasa app with excellent scheduling options. Smooth dimming from 0% to 100%. Full Alexa support with voice commands for on, off and dimming to any level desired. I have many Kasa smartplugs. None have failed and all work flawlessly. Highly recommend!

Excellent with a few *
I picked up 20 of these because they were under $14 each, making them even cheaper than the lowest-cost Chinese Smart Life dimmers. For the price, they deliver a lot of value and functionality.Pairing these with the Kasa app was straightforward and hassle-free. Linking them to Google Home and Amazon Alexa was just as easy, and I had zero issues getting them to work with both platforms.One of the standout features is the design. Since the cable extends away from the unit, you can plug it into the lower outlet and still have room for something in the top outlet. This is a big advantage over some of my Lutron dimmers, which are bulky and tend to monopolize the entire outlet.Another great feature is the grounded outlet. Unlike many dimmer controllers, such as my Lutron and GE models, which only have hot and neutral connections, these include grounding for added safety and versatility.It is worth noting that these dimmers only support up to 4 amps, so you need to keep your load under 400 watts. For most modern LED lighting, this is not an issue. However, for some of my outdoor Christmas lights, which are older incandescent strings, I had to limit the number of strings I could connect. It was not a big deal, though, because these are so affordable that I just used a second one to handle the extra load.Finally, I was impressed by the lack of flickering. Even at low dimming levels, there was no noticeable flicker with my LED lights, which was a pleasant surprise. Overall, these dimmers are a fantastic value and work flawlessly indoors and outdoors.

Easy to Program and Convenient for Outdoor Use
This timer is really easy to program, which I prefer over the older-style timers that look like clocks and require you to manually press down all the tabs to set the time. Those can be a hassle, especially since you have to constantly adjust them as sunrise and sunset times change throughout the year. What I love most is that I can program it to turn on at specific times and set different schedules for different days of the week. Plus, it automatically adjusts for sunrise, sunset, and daylight savings time, eliminating the need for manual resets every season.I mainly use it for outdoor fountains and lights, and it works perfectlyâmaking life so much easier. I also use Kasa light switches as well, so it is nice to have everything on the same app.

Kasa Good
Product: Kasa / TP-Link Outdoor Smart Plug, single outlet, model KP401Gist: overall I like it and would get it again although I’d actually get the one with 2 plugs insteadGood: Kasa Smart app works good, the Kasa/TP-Link products are good quality and good function with the Kasa App or the Alexa App and Echo devices, actual setup of the plug was very simple and easy – just select it in the Kasa app and then go into Alexa and it already has it ready to go without even doing anything.Not so good: you have to have the Kasa Smart App on your phone, you need a username and password, the unit is not waterproof – it is weather proof – that means no direct water contact I’m pretty sure. It is designed to be plugged into the outlet and for the unit to hang down by the cord about 7 inches with the actual socket facing the bottom. That way rain will not enter, just run off the sides. Just keep that in mind when determining if this style plug will fit into your scenario.Details: My first smart plug was a Kasa/TP-Link product that I purchased off Amazon in 2017 and in 2024 it is still operating perfectly with Alexa/Echo so I expect this item will also last a few years.Since I already had a Kasa account setup in 2017 all I had to do was login and add this new device. Well, I haven’t accessed that account since 2017 and haven’t had the Kasa app on my phones since then either. I’ve just been using the Echo devices to control my Kasa devices ever since initial setup years ago. So here is the process for me to setup this device:First: Like most smart devices you need the 2.4 GHZ band of your internet router to be active along with the 5 GHZ all the time.1. download the Kasa Smart App onto my phone (I ditched Apple so I use the Android version now)2. open the Kasa App – it will want a login before anything else can be done. If you have an existing account and don’t know your username or password then just click recover option and it will send a link to your email it has on file. Use the link to reset the password. I actually had my password written down but I think since its been years since I logged in it was disabled and that’s why I had to do the reset.3. After you login to the app, just click the plus sign for add device and scroll through the types to select your Outdoor Plug and then the KP401.4. Assign a group or routine in the Kasa App if you want5. Once you’re done with the Kasa app if you go into the Alexa app it should be already setup and ready to use.I didn’t give it 5 stars because everything can always be better and I think the amount of cord this hangs by should be shorter. For some reason they didn’t think so. It works well but looks a little clunky in my patio scenario.

Great smart plug, works as expected.
Paid well with Alexa, easy to set up. Reconnects automatically when I unplug it from the outlet and plug back in. I use this for my portable swamp cooler with a manual switch to come in as my house heats up in the afternoons to keep my kitties cool and save money by not having to use the AC.Â

El producto se recomienda solo, y es parte de la familia TP Link, dicha marca fue recomendación de un buen amigo Gerente de IT y utilizado en cierta empresa que de verdad estos productos trabajan y valen cada centavo por el servicio que dan non solo en cuanto a este tipo de contactos, desde ahora la bomba de la cisterna es controlada desde el teléfono móvil, entre otros equipos tal como la presurizadora que abastece los servicios en toda la casa.

Weatherproof outdoor dimmer. Comes with a rubber flap to cover the outlet if nothing is plugged in. Thereâs a button on the unit to turn it on/off and dim. Main control with more features is done through the Kasa app. Itâs a well laid out app with editing and personalization abilities. You can set a timer to turn the light on or off. You can also create a schedule for one-time or daily operations. You can even choose the dim level. There is also an away feature for when youâre on vacation. The package also contains a wire clip to hold the unit against the wall using the 4â cord. The great thing with the Kasa app is that you can control all of your Kasa items from one page. Kasa offers switches, dimmer switches, motion switches, motion dimmer switches, 3-way switches, switched outlets, power strips, dual exterior outlets and this single exterior dimmer outlet. I currently own multiples of each of these items for over a year now and Iâve been very satisfied with the experience. I have had no issues with any device and the app has worked flawlessly. Currently, all items only work with 2.4G (no 5G). If youâre looking to start creating a smart home, Kasa offers a wide range of items for your whole house. Itâs better to get items that all use the same app to make things simpler and more convenient. The only thing missing, that I hope Kasa will eventually release, is the remote switches that Lutron offers for their switches. Their Decora style switches and dimmer switches are linked to a dedicated Lutron switch. You can then mount these remote switches in other locations, converting a single-pole switch into a 3-way. They even offer the mounting hardware and cover plate that looks like a wired switch. You can also leave these switches on tables, or wherever a switch would be most convenient for you. If Kasa were to offer their own remote switches to control their light switches and outlets, it would be the perfect smart home system. Other than that, theyâve covered everything else.
