Kasa Smart Light Switch HS200P3, Single Pole, Needs Neutral Wire, 2.4GHz Wi-Fi Light Switch Works with Alexa and Google Home, UL Certified, No Hub Required, 3 Count -Pack of 1 , White

Great high quality reliable smart switch
I am in the middle of a large home renovation and have ordered and installed a mix of Kasa smart switches, dimmers, and 3 way switches. They are all super easy to install and setup, and also look fantastic and modern.
The only complaint I have is with the included decora wall plates. I love that they are the jumbo size plate, but I hate how they install. They are a simple snap on design that snaps onto the outer frame of the switch itself. The issue I have is that if the mounting depth of the switch is not exactly right, the plate’s tabs will not snap into place and the plate wont install at all. Issues like this can be remedied with the use of outlet/switch spacers, but you also need to be careful with these, as too many spacers will make it so the plate wont sit flush on the wall. Other manufacturers use a 2 piece design, which I find far superior – an inner plate that secures the switch to the wall, and an outer decorative plate which snaps onto the inner plate.
Connecting to wifi is very easy, as the Kasa app is intuitive and walks you through the process from start to finish. I have had zero connectivity issues. Nice and stable!
Overall, TP-Link’s Kasa series smart switches are a great product that I highly recommend. Great stuff!

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.

Fácil instalación, funciona muy bien manualmente, con la aplicación y con Alexa

Like the TP-Link Smart Plugs I already own this was simple to set up and works slick.
TL;DR – Simple to use and rock solid performance, use the app anywhere, better than any timer from the hardware store.
Look in the Apple and Google app stores for the “KASA” app. I’ve used both and they simply work without any tweaking. To use KASA you will need to create an account if you want to use the app remotely, no need if you only want to use it within your Wi-Fi range. You can do this right through the app.
If your already using Amazons Alexa you’ll be happy to know that this device can be controlled through Alexa.
A nice feature. When switched off there’s a muted white LED that’s visible in the dark.
The switch has three buttons, the big main light switch and two smaller buttons located directly beneath. To turn on the switch manually, depress and release the big switch which looks just like a standard light switch. It also fits into a standard single switch electrical box, it will also work in a dual or triple switch box as a standard modern cover plate made for the wide rocker type switches will fit perfectly over the portion around the main switch.
I had looked at some of the non Wi-Fi options, the light switches that use a proprietary remote that’s similar to what you would use with a TV but they all have limited range, maybe 30 meters if you’re lucky. The TP-Link system using the KASA app allows me to control these smart devices from around the house or when traveling through another province or country. Once you have connectivity to the internet it doesn’t matter where you are, you can control these devices.
One aspect that really appeals to me is the ability to set up schedules for the devices to turn on and off. If you already use timers to turn on lights while your away you’ll appreciate that the app allows you to do that plus configure (this part isn’t techy) the lights to come on randomly between certain hours which really makes it appear that someone is in the home. You can set up several schedules if you like. Any burglar with at least three grey cells knows to watch a home for a few days to see if there is a repeated sequence when lights come on. Once they discover the routine its actually the green light they need, they now know no one is at home since very few people always turn on the lights in certain rooms at the same time every night. This ability to set random schedules is a big bonus and really makes it appear that someone is in the home.
There’s one thing you should know here, this is not like the smart plugs when it comes to installation. Those you simply plug into the AC outlet and then plug in whatever it is you want to turn on remotely. This device completely replaces a wall switch which means you need to wire it correctly so I strongly suggest you hire an electrician or someone who has the skills to handle this if you aren’t qualified.
Once the switch is installed the setup and connectivity portion is easy, it’s all done through the app and by pressing the little button to the left side (Reset) beneath the main switch. Again, this part is non-technical, simply follow the steps outlined in the very easy to follow instruction sheet which walks you through the 3 minute process. After that it’s easier to set up schedules and other features than entering a friends contact info in your phone.
Comes with all the hardware needed to install in a standard electrical box including wire nuts Marretts).
