Kasa Smart Dimmer Switch HS220P3, Single Pole, Needs Neutral Wire, 2.4GHz Wi-Fi Light Switch Works with Alexa and Google Home, UL Certified,, No Hub Required, 3-Pack

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.

Very customizable. I’m obsessed with these things. I was very impressed with the range of customizations available in the app settings. Things I wouldn’t even have thought about as features but seem like they would be really useful for the right use case. Such as dimming the lights (or turning them on) over a 10 min time frame. Just a very well thought out feature set in the App. I have two other types of switches from Kasa (3-way and non-dimmable single pole) and I have been impressed with all of them, although these dimming ones are my favorite.The only downside is that they are quite large and really fill the space in the electrical box, so if you have a small box or an excessive amount of wires this might not be feasible for that application. I did have to skip over one of the switches I planned to swap out because of this problem.

Amazing Dimmers. It took me the longest time to buy the lights for our theater because all I could get was LED and they don’t dim worth crap. But thanks to these dimmers, the lights now can dim at the level of incandescent lights. I love being able to control them from my phone through the Kasa app and I can also group the lights together with the other lights as a group and dim them both at the same time. Incredible dimmers that are cost effective and smart!
