Kasa Matter Smart Light Switch: Voice Control w/Siri, Alexa & Google Assistant | UL Certified | Timer & Schedule | Easy Guided Install | Neutral Wire Required | Single Pole | 2.4GHz Wi-Fi | KS205

UPDATED-Very easy to upgrade just takes time to do it right
UPDATE:I pride myself on being unbiased and being honest with my reviews. My original review stands, these are still great switches and if I had to do it again, I’d still install these. However out of (now 32) switches in my house, one had issues. The small reed switch(?) used to toggle on and off the relay inside, or the relay itself failed. No problem I said to myself, I registered these for the 2 years warranty at the company, and one of these which operates a vanity light, wouldn’t engage. The click it makes is weaker than its neighbors. I reached out to support for an RMA & it took a week and a half going back and forth with support over email, wanting me to take the wall plate off, expose the wires, to take a picture and video to prove I wired this correctly, video it not working properly, and who knows what else they come up with. It had been installed for almost a year without any issues. I’m experienced with residential AC wiring & given the fact these were working for a year closed up in a 4 gang box with 31 other switches also working fine, they kept insisting. I am busy and don’t have time for the back and forth, and considering these are modestly inexpensive, I just bought a replacement instead of this extra run around. Be aware if you need support, it’s going to be a hassle. They did honor support for me in the past with bad light bulbs but I didn’t have time for the hassle for waiting for a reply after a couple of days in the middle of the night. I’m reducing my previous 5 stars to 4 for now because of the tech support grief.Original Review:I recently completed my project of automating the house’s lights. I used a mix of all Kasa switches, single poles, 3 ways, dimmers and even a 3 way dimmer. It was an investment even though these are somewhat cheap in a 3 pack, I needed up automating 31 light switches in my house (no joke). I bought a few at a time and took 5-6 months of the project a little at a time. Now I can control all the lights with Kasa and Alexa. I grouped them and created routines activated by voice, time (sunset/sunrise) and even event-based (turn on a light in the bathroom-it turns off automatically 10 mins later). The features of automating the home is essential now that I have the right devices!These Kasa switches are reliable and good quality. If you are confident to do your own work but not sure how to wire these (like the 3 way switches), the Kasa app shows you step-by-step how to do it. Very Nice!! I noticed right away the wires were tinned to give them a solid connection when wire nutting the switches. The setup was easy in the app being these are wifi, and they are very easy to operate. They come with a single gang cover plate, but in most cases I had 2-3 switches in a box so I bought other covers to have the same look and feel. I also got a cover to cover switches that should not be turned off like my yard floodlights or driveway camera. But I can still oowercycke them easy with the Kasa app or Alexa.Take your time to do the project. If there is any doubt on electrical-seek a professional. I’m a capable DIYer so I did mine on my own. The biggest problem with these was pulling out the neutral and ground wires which were never used for the old switches.The other biggest issue I had was how the builder’s electrician for the house building, was lazy about how things were chained together.If you tackle this project, invest an extra $20 ina voltage detector and a line tracer (the orange thing in my pics) this helps you trace which switch is powere by what breaker so you can shut them off. In some cases, I had 2 feeds into a box which powered one light or another, so it helps to spend the extra few $ to have a simple tool to be safe. Wire nutting is also important. Be sure your connections are secure!

Just seems to work
I installed these myself, and they work great! We already have a hub with smart bulbs, but you aren’t really supposed to use smart bulbs outside. And I wanted a way to control my outside porch light that was more complex than a dawn to dust sensor. Enter these things.INSTALLATION:Setup was easy, but I would implore anybody unfamiliar with wiring electrical things to take off the cover of their switch and study the wires. Don’t touch anything! This is very easy to install if your wiring is right.So, my understanding of the modern electrical code is that electricians aren’t supposed to connect multiple things directly to a switch, but that doesn’t they didn’t back in the day. The instructions make it seem like you just connect four wires to four wires on the switch with wire caps, but that is only if your wiring was done up to current code. My wiring was a lot more chaotic with a light switch being used to piggyback power to a quarter of the rest of the house! So, just something to be very aware of for anybody unfamiliar with it. The app claims to guide you through installation but it literally is only for perfect, absolute best case scenario wiring.If you open your box and there is a wire nut of white wires, bare copper ground wires, and just two black wires connected to two different screws (or slotted in the back with nothing on the screws) on the light switch, you should be good to go. If there are multiple wires connected to one screw, or multiple wires connected to one screw with additional wires coming out of the stabs in the back, your wiring isn’t up to modern code and it will be a lot more complicated of a process that the app WILL NOT guide you through.PROS:The switches are reliable and will trigger when commanded with a phone, but we have a small house with good WiFi. We have two switches right next to each other in a gang box, but there doesn’t seem to be any interference or anything. I was a little worried about that.The switches also come with a decora style plate, which is nice. I recently bought a dumb dimmer and it didn’t come with a plate at all.The app is fine even if is a little cluttered with all of the their other smart products. Setup was very easy with the app.So, I have one of those routers that has 5 and 2.4 GHz networks, but they combine it into one name, basically. So, like, I can’t have my phone intentionally use the 2.4 GHz network. It just defaults to the 5 GHz one no matter what. This can be an issue with some smart devices, but not with these. Note that you do need a 2.4 GHz network, but it will work fine if your router combines the two.The app also lets you do nifty stuff. So, we have two light switches in the kitchen that control two different sets of lights, but one switch is blocked by the kitchen table, so that switch is really annoying to use since you have to reach over the whole table. Well, I just used the app to basically link that one with the easily accessible switch, so now one switch will turn on both pairs of lights, although there is an understandable one-second delay between the second one turning off. We’ve had a few guests comment on how weird the delay is, but I don’t care.I don’t know if the description even mentions this, but the subtle illumination is awesome! I didn’t even know it had this, or that I apparently need it in my life, but there is a very faint glowing circle when the switch is “off” that makes finding it in the dark so easy. I love it! I almost want to convert all my switches to smart ones just for this.CONCLUSION:I’m really happy with these. They just work and do exactly what I wanted. Plus it has neat features I didn’t even know I needed in my life. I’m beyond tickled.

They’re great. Easy installation and setup. It works with their app or Alexa. I use Alexa and its very convenient to control the lights with voice commands. Bought two moreIf you have 3-way switches they also have that. Just make sure you buy the right product
