only does one bulb 5/2/2020 1:48:55 PM

Pros: app was neat and helpful

Cons: it will not work on a light fixture that has more than one bulb. this and ALL TP links light switches will only run one bulb. they told me they do not offer one that handles multiple bulbs

Overall Review: be nice if they specify that it only will run one bulb and thats it.

Manufacturer Response:
Hi Preston,

Thank you for your review. As long as the bulbs in the fixture do not exceed the total load limit of the switch, and are controlled by a single switch already (i.e. a bank of lights or a multi-bulb fixture connected to a single switch), the HS220 should have no issues controlling it.

Our Support Team is always happy to answer any questions you might have about our products. Please feel free to e-mail and we'll gladly have a Support Agent follow up with you directly.

Best Regards,
TP-Link Support

No complaints here 9/25/2019 5:02:57 AM

Pros: + easy to install
+ works perfectly
+ no more telling the kids to shut the light off

Cons: - doesn't dim LEDs quite as low as I would like
- white is the only option

Overall Review: I've been very happy with all of my Kasa purchases and this one is no different. It was very easy to install and the instructions were perfect. Everything works as expected. I've been replacing my switches that the kids always leave on with smart switches. This makes turning them off and on so much easier. I know it sounds silly but it's really nice especially when you set up schedules. When the lights go off it's bedtime and the kids know that without having to tell them a million times.

I should have bought more! 9/24/2019 8:43:55 AM

Overall Review: This light dimmer switch works perfectly with my LED B20 bulbs and I'm really regretting not purchasing more of these switches when they were discounted to twenty bucks not too long ago. I'm keeping my eyes out for a sale again!
One of the things I was concerned about with the switch were some reports people had about tight spacing within the switch box. After replacing several light switches with non-smart manual dimmers in the distant past and really having to jam everything back in, I was concerned it would be REALLY a problem with the switch. I'm glad to say I did NOT run into that problem with this switch.

Great Product! 5/2/2019 11:42:10 AM

Pros: If you understand on how to install a regular switch.. then this will as easy. other wise have a certify electrician/IT install it for you.

Cons: No Cons.. so far,. Product works as expected.

Overall Review: I will be great if the application will allow to set groups of items into one and turn all at once and still have the option to do one at the time.

These smart dimmer switches work very nicely for me. 3/20/2019 11:51:56 AM

Pros: Already had some TP-LINK devices, so Kasa app was already on my phone. I launched it, clicked on the button to add a device, and up came instructions which were clear and precise. I installed three of these in my living room, replacing three 30 year old dimmers which actually worked OK, but I wanted wi-fi control. All three devices installed and run perfectly from both the app and using local control. I have never had to use TP-LINK tech support, so have no experience with them (unlike the other reviewers, who it seems have had negative experiences).

Cons: The requirement to have a neutral line at the install point is kind of annoying for some setups, but see below.

Overall Review: Using incandescent bulbs because my wife likes the way their color goes warm and soft when dimmed, so can't comment on dimming LEDs, but these things just work great on those incandescents, both as local control and through the app. It's amazing how long incandescents will last when they're run dimmed most of the time - of the five bulbs being controlled, four are as old as the old dimmers (so 30 years old, and used pretty much daily).

As for the neutral line requirement for installation...on this triple setup and one other non-dimming version I have here, I had no neutral line available in the box. The gang box where I installed all four was a true measured ground, so I tied the neutral and ground wires together and connected them to the gang box ground, and that worked FOR ME. IT MAY NOT WORK FOR YOU AND MAY CAUSE OTHER ISSUES, so get a professional electrician's advice if you're going to try doing that. Remember, you're dealing 120 volt electricity, so better safe than sorry.

Extremely frustrating customer service/returns process 3/4/2019 4:43:39 PM

Pros: - 1 of the 2 I bought works well

Cons: - The 2nd one I purchased was a dud
- TP Link has _the worst_ customer service I have ever experienced

Overall Review: I have nearly a dozen TP Link smart home devices, from smart plugs to switches to cameras. I like them, they generally work well. But after my experience with their customer service department, I'll be searching for another brand.

I purchased 2 dimmer switches from Newegg and had 1 installed by a professional electrician. It was defective - the lights wouldn't turn off via the app or the physical buttons on the switch. Stuck on. Electrician swapped it out with the 2nd one which worked immediately.

I contacted the manufacturer by phone, they acknowledged the defective unit and opened a case. Since then I have literally exchanged 20 emails with them, only to get nowhere. It went from "create an account on the warranty portal" to "your email address is invalid, create another account on the warranty portal" to "oops, we deleted your account by accident" to "okay we fixed that, now request a return" to "oh, by the way, now that you're finally ready to return the device, we're going to charge you shipping". It is _shocking_ to me that such a simple return process could be made so complicated and frustrating.

TP Link, you sent me a defective device. Make it right. And treat your customers better. Because you just lost a good one.
