   They just work!
   Love these smarts switches! Why?Because they just work!Power outages, wifi problems, you name it as soon as they are able, they reconnect and just work as if nothing happened. I have over 20 of these installed in my house and have been totally trouble free since the spring of 2022. I have had them tied to google home and Alexa through multiple accounts it has been totally seamless.However, If I am being critical I would point out the mechanical side of the switch feels somewhat cheap and doesn’t not give a satisfying click when pressed. Also the switch is quite bulky on the backside make sure you have plenty of space in your switch boxes, making room for this extra bulk is the most time consuming and tedious part of the install if your boxes are already crowded

   Works great for both three way dimmer and four way configurations
   This smart switch comes with two sets of switches. Each set includes two wire nuts, two mounting screws, snap-on face plate, wire labeling stickers, and the switch itself.

   These Just Work
   These 3 Way work. Now, I learned you don’t “have” to put each one on the same circuit, so if you are okay going against the TP Link recommendation, since they come in pairs, you can put 1 on a plug and have it work, and put the other one on a different plug and name it separately, and BAM you have two 3 way circuits that are on your Alexa control (and Kasa App control etc). I do have some “4 way” switches…..and they area PAIN. I thought they were 3 way, and one of them I got to work (don’t ask me how, ha) but the other I cannot. They have an extra wire, and it’s a huge pain in the rump. In general, it’s awesome though. I copied the review from the “smart plugs” as well, because all of the information is essentially the same, except for the install which for the switch you have to put in the wall switch (TURN OFF BREAKER< HA) and the plugs are just plug in and then the lamp or whatever goes in the plug. The switches you have to know how to wire in a replacement switch in the wall.I will say, these switches are much bigger than just a switch (inside the wall box). I've done other timer switch replacement, and that's the norm. The problem is a lot of these boxes have TONS of wiring stuffed into them. On a few, especially ones that have 3 or more switches in one long box, I've had to pull all of them and trim wires to make them fit. I didn't trim where they weren't workable, but I did get a ton of the excess removed.These plugs work....that’s it, they work. All of the TP Link smart home plugs and Switches work, and work flawlessly that I can see. The Kasa app is great, works flawlessly as well.I have 8 of these so far, and they are mixed in my home with wall switches (TP Link switch and 3 way switches) to all run with Kasa app that is TP link that then works with the Alexa Amazon Echo's throughout the home.These things are truly plug and play. You plug them in, open the Kasa App, and "add device" and bam, it's super easy to follow the directions and add to WiFi in the home. Then open Alexa App on the phone and all of these TP Link items are there in the Smart Home section. It just works, and works flawlessly.The entire system, I add "Routines and Scenes" and you can do all kinds of cool things. In the Alexa App the Routines, I can turn on lights and play the weather on the Echo and then have it start music. I can say "Alexa, turn on the Accent Lighting" and it turns OFF the ones that I want off and don't think are accent, and turns on the ones I say to turn on, and it is super easy.The Kasa app also has timers as much as you want. You can set "turn on" and the time, and create as many as you want, and turn off the same. My Christmas lights indoor and outdoor were all on these indoors and the plugs for outdoors are on switches, so bam those all worked on timers there. Same with my patio outdoor lights.The "only" glitch I've had in the months of using these......I switched Broadband Providers from Uverse to Spectrum. The new WiFi router, I set up the SSID to the exact same, same password, and it "should" have all just connected and never had a glitch. After 2 hours of weirdness, and trying to reset one of them, and get the TP Link to work.....I spent more time online and realized these are 2.4Ghz ONLY. I had set up the 5Ghz Wifi to be the original. I went in and made the 2.4G the old one, and BAM, everything worked FLAWLESSLY again. So, the 5Ghz wave I made the SSID-5G and all was right with the world once again, ha.My wife said this was silliness......she also said that when I got our first DVR 20 years ago......now the DVR is full of HGTV.....and she admits these things are great.

   Easy wiring, easy wi-fi connection, and the product looks great after install. App is really easy to use too.I have 20+ units installed around my house, and they all work great. Motion sensor units work great, and the dimmer switches have memory, so the brightness level is always perfect.Only downside is the height of the switch. They don’t fit inside older (80’s) boxes very well.*** Just don’t buy used switches ***Often they come damaged, or the incorrect switch is in the wrong box. Not worth the hassle of a few dollars.

   I have purchased a few TP-Link/Kasa products over the years and they have yet to let me down.These switches do exactly what you would expect and at a reasonable price and they work flawlessly.Installation was easy with the instructions provided (they even include little label stickers to wrap around the wires to make keeping track of them easier) and, once all of the wiring was done, setup took no more than a couple of minutes (including adding to Google Home for automation).Very happy with this product.

   El producto funciona de una forma maravillosa, la tengo conectada a una bomba de agua, prende y apaga según mis programaciones y con Alexa mejora la experiencia.IMPORTANTE. Antes de comprar este producto deben considerar que necesitan los siguientes cables en su instalación eléctrica:1. Línea Activa “Con energía”2. Línea Neutra “Retorno de energía”En ambos espacios donde lo quieran poner.Lo anterior se los hago saber ya que los switch de escalera normales usan una entrada de energía de un lado (Línea Activa) y una salida neutra para el otro switch. Ese fue el problema al que me enfrenté ya que solo pude poner uno. De otra forma tenía que jalar una Línea Activa a mi segundo socket lo cual es inviable sin pagarle a alguien…>.<

   Excellent product, I had an existing KASA HS200 using since last 4 Years, little doubt when ordering but worked well in India. I am using this switch as one way switch for garden lighting. Most reliable product in this category.
