Kasa Matter Smart Dimmer Switch: Voice Control w/Siri, Alexa & Google Assistant, UL Certified, Timer & Schedule, Easy Guided Install, Neutral Wire Required, Single Pole, 2.4GHz Wi-Fi, 3-Pack

Don’t buy a cheaper brand
This one works great! I had originally put in a very slightly cheaper smart dimmer in and had endless connectivity problems. I have this one connected to both Alexa and Siri and I have not once had an issue. 

Great switch, needs more smart actions
I installed 25 tp-link switches (combination of dimmer, switch, and 3 way switch) in my home, and one wemo dimmer.Installation: The tp-link dimmers and switches have different attachment hardware (where you screw the switch to attach it to the electric box in the wall). This is annoying because the switches have a thick plastic, while the dimmers are metal but have a piece of plastic that screws onto the top of the front which has to be removed. I personally prefer the dimmer metal hardware. When you install a dimmer next to a switch you have to really fiddle with them to make the two different sizes look the same after the cover is on.What I like:I really like the fact that I can control these from the switch, my phone, or the from google assistant.I also have a in wall wemo dimmer. When I tell google to turn off or on the lights the wemo is significantly slower to respond then the tp-link. For tp-link the lights start to turn on//off in probably .5 sec while the wemo dimmer may take 2-8 seconds to start to respond.Look – the switches and the covers have a bright shiny finish. In most cases I was not able to use the included cover as they are installed in double or triple switch settings, but I like them where I was able to use them.Light compatibility – I’ve installed these with multiple kinds of dimmable LED lights and they have all functioned well.Light range – I replaced my living room light which originally had the wemo dimmer switch and I noticed that the tp-link uses a greater range of the light bulb – i.e. it dims more and 100% brightness is brigher which I like.These also pretty quickly reconnect to wifi after I flip the breaker off or power outage (unlike some of my other smart devices that I have to setup over an over again with every power blip)Enhancements I would really like:Enabling third party triggers. I use IFTTT to integrate multiple smart things together. While these dimmers are compatible with IFTTT – they are only able to be used as THAT devices (in the “if this than that”(ifttt) recipes). So for example, with my wemo switch, if I wanted to turn on/off some other smart device when I clicked the wemo dimmer switch, I could use the wemo click as a THIS action or trigger. But these switches I can only use to respond to other actions, for example, when my door sensor senses that the door opened I can turn on the entry way light.True Instant on/off: The dimmer switches have a setting where you can change how fast they dim on and off when you click the switch. One option is “Instant”. When I have it set to instant, it really just dims on/off fast. I have a non dimmer switch right next to a dimmer switch and when I click both at the same time the dimmer light takes longer, probably a second to turn on, while the non-dimmable switch is instant. This would also probably help with non-dimmable lights. I had non-dimmable lights attached to some of my dimmers and these acted very poorly even when set to instant on. They really buzzed and some even continued to buzz loudly while on.Always on circle light in switch – In places where I have three dimmers together, when I turn one light on, that switches circle on the switch turns off. When I go to turn the light off I instantly think that the switches with the light on are the ones that are on, so I click those two only to find that neither of those lights were on and end up cycling through all three switches.In the kasa app when you select a dimmer or a switch the UI is completely different, it would be nice for them to be more similar.What I don’t like -The click. About 1 out of every 4 times that I click the switch it doesn’t turn on/off. Probably similar to learning to double click on a computer mouse for the first time (for those that can remember that). This could also probably be resolved with the instant on/off I mentioned before. Because it takes about a second even on instant on for the light to come to full power, when you click on and didn’t click hard enough you end up walking past the switch thinking it is just takings its second to dim on, but then you have to walk back to the switch once it actually doesn’t work. Some of my switches also have a bit of a squeaky click, which is also annoying.Note about 3-way switches – Even though my house was built fairly recently, for every set of three way switches, only one of the two wall wirings has the white wire. Luckily these can be paired with an old dumb three way switch and work quite well (i.e. you can use a single 2 pack of 3-way switches for two separate sets of 3-way sockets)Note about wifi – I have mesh wifi in a smallish house so my wifi coverage is good throughout and wifi connectivity has not been an issue for switches.Update Feb 2020:Smart actions – Auto off action. I really like this feature. I have my bathroom vent fans set to auto off after 15 minutes, and I think it has always worked except for one time my WiFi was down. The problem, your only allowed 3 smart actions. I’d love to be able to set more. My son uses the bathroom at the far end of my house and leaves the light on every time. A 15 minute auto off would be perfect. It would also work for closet and hallway lights. TP-link please add more smart actions.

I have had a smart home with 50+ devices for about a decade, since Apple first brought out its HomeKit smart home system. I have a lot of experience with the benefits and also the many hassles of smart home devices.Firstly let me comment on the physical product itself, and the company behind it. Great design. Great quality. Committed brand, with a good track record I think you can trust. Easy to physically install if you are comfortable with connecting wires, and can turn off a circuit breaker. You MUST have white “neutral” wires, which typically any electrical system done since the 1980’s will have. Instructions are straight forward. You might discover some of your existing switches are not wired in typical ways. If this is the case and you don’t fully understand it, get an electrician. I think most people will be okay.BUT … from an all around software setup perspective, this is by far the most aggravating installation experience I ever had – until it wasn’t. This is the FIRST Matter protocol device I have installed in my Apple Home. I DO have the required Matter/Thread routers that are needed. In this case of an Apple Home, several Apple TVs and HomePods. If you use Google Home, or Alexa, or other you MUST also have in your home a “Matter Hub” capable product from Google or Alexa respectively.I spent almost a full time week, googling, trying various things, getting frustrated, and I would rate myself a 9/10 on expertise in this area. Until I learned the best trick. You HAVE to FULLY commit if you want to move to the Matter, protocol and I think you SHOULD. Even if you do at first get it working without this drastic step, I think you are just pushing hidden problems into the future. Start FRESH.All those smart home rules, profiles, pairings, etc you have built over the years – you should DELETE THEM ALL, and FACTORY RESET ALL your smart home devices. Delete your ENTIRE home profile. Start over completely. Drastic yes. But just like it is much easier to build a quality new home from scratch, rather than patchy renovations to an existing home, the same applies to a smart home when moving to a very different technology, in this case “Matter”.If you want to get into the Matter ecosystem, and I think any serious smart home enthusiast SHOULD, you have to understand that you are much more on your own right now than by sticking with a current proprietary ecosystem. The attempt to make Matter work with many different platforms, means the ability for product manufacturers, and Ecosystems – like Apple, Google, or Alexa support, to assist you is very limited, even when they want to.One MORE step. Do the same with your router. FACTORY RESET. It also plays a core essential role in the reliability of your smart home. If you have a cheap router you should really consider something higher end.When I took the deep dive, and started from scratch, I was able to set up all my Matter devices with ease. Another suggestion – just because matter claims to be able to support multiple home ecosystems out of the box, DON’T do that. You are asking for trouble, Pick 1 like HomeKit as I did, or Google Home, or Alexa, or SmartThings, or other platforms, and do EVERYTHING on that ONE platform. Also install the manufacturer specific apps for direct control of your devices, outside of any ecosystem. Reduce complexity, don’t embrace it.

Yes, Matter is still quite frustrating, but most of the issues should be solvable through updated ecosystem software and product firmware. I still believe it will become THE standard, likely the ONLY standard in the future. So unless you need features not yet supported by Matter, I think Matter devices are worth the initial pain, to future proof your investment.Hope that helps !
