Kasa Smart 3 Way Dimmer Switch KIT, Dimmable Light Switch Compatible with Alexa, Google Assistant and SmartThings, Neutral Wire Needed, 2.4GHz, ETL Certified, No Hub Required, White (KS230 KIT v2)

Wow, welcome to the 21st century
Wow, leave it to tp to come up with this amazing product.Easy to install, durable and, simply, the best product of its kind in the market, believe you me, I’ve tried so many different products and returned them all after major disappointments.With this, I feel spoiled and cannot stop myself from calling on Alexa to turn on then off or dim and brighten the ceiling light controlled by this smart, sleek and durable dimmer, I give this product 10 out 5 stars.BS: follow the wiring instructions carefully then you won’t have any difficulties setting up this amazing dimmer, also you have to have the pair dimmers installed (main and satellite). Do not listen to some YouTubers who claim you can use only one, this model requires the two sides installed.You will be amazed when you pair it with Alexa. All day I’m calling for Alexa to turn on, off, dim or brighten my living room ceiling fixture, I’m going insane.

Works great but needs either HomeKit or Matter support
We love how we can turn out the lights over our kitchen island without having to get up from our couch. We love the way the lights can be dimmed either from an app or from the switch itself. We love how there’s a small white ring-shaped LED on the switch that you can see when the lights are off. It disappears when you turn the lights on. It is a very dim, unobtrusive ring of light, but is plenty bright enough when the room is dark. The same light ring comes on in orange or green when you program the switch in the Kasa app. They were fairly easy to wire-up, install, and program. I’m a fairly competent DIYer, but I have a brother-in-law who’s an electrician, so that definitely helped my confidence level.The system isn’t perfect, though. It works with Alexa and some of the other “smart home” apps, but not Apple’s HomeKit. Granted, way more people use Alexa and other products, so there isn’t a real need for TP-Link to bring out the 3-way switch in the Apple format. However, there is a new standard “communication protocol” (not sure of that term) that has been rolling out called Matter. If you don’t know what I’m talking about, Matter is a communication “standard” that all the MAJOR manufacturers of smart devices have adopted to allow these devices to talk to each other. The idea is, you can have an Apple TV 4K and use it to operate smart items that were originally only set up to use Alexa, or one of the other systems. I may not have all the “jargon” right, but I think I am communicating the general idea of Matter correctly.Kasa have just come out with new single-pole switches that use the Matter standard. I bought and installed two of them on some of our other kitchen lights. They were as easy to program as the 3-way switches I’m currently reviewing. Now I can use the Kasa app OR the Apple HomeKit app (and my friend Siri) to turn those lights on and off. I’m hoping TP-Link will come up with a way to convert these 3-way switches in the future, but I don’t know if it’s possible. I asked, but TP-Link have no comment about their plans (which makes me think they can’t or won’t be doing so).So 2 thumbs-up on the 3-way Kasa light switches. The reason I didn’t give a 5-star rating is because of the need for a neutral wire in the switch box and how big the bodies of the switches themselves are. I had to dig out the bundle of stiff, 27 year old, 12-gauge, solid wires, separate them, and reconnect the bundle of neutral wires with the neutral wire from the switch, using the biggest wire nut I’ve EVER seen. Then I had to do the same thing with the bundle of ground wires that were jammed in the back of the box too. The extra wires and bigger wire nuts made it very hard to get the switches into the box. Putting all that aside, I’m impressed by the switches and glad I did it.

Easy to connect anything (plugs/switches/etc) once u have the app setup. Motion switches r great and can set timing on them real easy. Only issue which is minor is u can’t arrange the order of your switches… to do it u have to add a numeri al digit to get the room switches to be in the order u want them to appear. (Ie: Living Room Light, Upstairs Bedroom, Bathroom, Kitchen, etc… need to put 1. 2. 3. 4…. in front of the rooms to get them to go in the order u wish to see them on the app. Not a biggee but would be better if u could just arrange them on the app with out numerical input.

1. Step-by-step instructions through the app are well written and super helpful.2. The label stickers for the wiring made things a lot easier.3. The Kasa app as a whole is very well done.4. Dimmer calibration is a first I’ve seen in smart dimmer switches and makes it a lot better than those without.5. Configurable fade in & out speeds is nice to have.6. Configurable long-press option is nice to have.IMPORTANT NOTE for Google Home users: Google Home sees this as a “switch”. Edit that setting and change it to a “light”. As a switch, it only lets you turn it on and off. As a light, it also lets you adjust the brightness. Thanks to another reviewer here for pointing this out.

This KS230 is an interesting piece of kit. It comes with a primary/master and secondary switches. The primary/master is the only one that requires a neutral wire.The primary/master switch is massive. It’s roughly the same size as the v1/v2 HS200 Kasa switches from years ago. I placed it inside of a 2 gang box and needed to cut protruding studs in the box with an oscillating tool so the switch would fit.Edit: I also purchased an HS210 kit 3 way set with 2 3-way switches. I read that you were able to use 1 of the switches for a 3-way set up, which I thought was really convenient. I wired up one of the HS210 as the main side (connected to line/hot) with my secondary/dumb switch at the load side. The switches worked as expected when they were toggled physically. However the HS210 couldn’t keep track of the ON/OFF state when the load-side switch was used.I had to pair the second HS210 in the kit at the load side before it worked as expected.Setting up the switch in the iOS Kasa app is a breeze. The first-time setting up the minimum dimmable level for the fixtures doesn’t seem to work correctly. The second time around, it manages to get the minimum right.I have this and nearly 20 other Kasa switches running in Homebridge and Node-Red and they’re great.
