Switches work as advertized – Some improvements needed to get to perfect –
Summary:The three ways HS201 kit replaced my existing HUBBELL switches.The HS201s are bulkier than conventional switches. You need to factor it into account if you are installing in a gang box crowded with wires and connectors. I expect that any smart switch will take more space, it is not specific to TP-Link.The TP-Link switches only function when a neutral is available. New and recent constructions may have a neutral laid out, missing with older buildings. Do not order the TP-Link smart switches if you don’t have a neutral available.The TP-Link switches have a thicker mounting bracket than that of my HUBBELL. I installed the HS201 in existing 4-Gang and 3-Gang boxes. As shown in the photos, my existing wallplates no longer provided a perfect fit between the switches and the wall. I called TP-Link CS, and they took note of the problem, and never provided any answer.PROS:works as expected;Central hub not required.”Kasa” app. takes you through the installation step by step, with DIY instruction;you need to create an account, one more email and password.Easy to pair with your Wifi network;Easy to configure to work with your existing Smart Home devices (Alexa, Google home, etc…)CONS:Switches are bulkier than conventional ones, it may be an issue in crowded gang boxes.Neutral is required for the system to work.Delivered with two single switch wallplates; the wallplates should not be included, but sold separately.TP-Link offers no 2-Gang, 3-Gang, 4-Gang wallplates to fit their switches.Customer Service was reachable, but did not follow up on my request: what wallplate should I use to have a perfect fit between the wall and a TP-Link HS201 switch. The original wallplate left a gap with the wall where the switch was installed.Be aware that if your installation deviates from standard, the Kasa app. will tell you to call support for assistance.Keep in mind that if you lose power, you will have to pair each and every TP-Link switch again! why couldn’t they use non volatile memory?The same goes if you change ISP.Not cheap!REVIEW:I have a staircase in my home, and three way switches at the top and bottom. This was the perfect testing ground for a set of Smart Switches.After a bit of research, I identified TP-Link as a good candidate, because they had a selection of products that would work in case I decided to add more components in my home.I renounced to my initial brand choice, because it required to have an extra hub to interface all the devices together.The installation did not go as smoothly as I expected, due to the larger size HS201s compared to conventional three way switches. My installation was done inside 4-gang and 3-gang boxes, with existing connectors and plenty of wires. The wires are not the flexible type, and it took me some time to bend them in a way that would allow the switch to fit. This also makes me question the possibility to add more switches. There is very limited room behind the HS201 and the back of the gang box. I suppose gang boxes manufacturer should start proposing deeper boxes to accommodate smart switches.Before you order any Smart switch, check the inside of your gang box, even if it is for a single switch.Before you order any Smart switch check your Wifi level close to where you will install. No Wifi, means you need to spend more money for repeaters. Not necessarily from TP-Link. There are other solutions.There are a few tools TP-Link advices to have before you begin, and I strongly recommend one of them; the contact less voltage detector, to ascertain you have effectively cut the power off.Identifying the wires require a little understanding of how a 3 way switch works, meaning load, 2 travelers, a ground. A conventional three way switch does not require a neutral. So you may have a little digging to do to find it.In my case, they did the paint job without covering the gang boxes, so all the wires inside were white! I had to remove the paint to be able to see the colors. You may also be in that situation. Do not hesitate to remove ALL the switches, and clean everything as required.In case of multiple switches in a gang, make sure ALL the switches are powerless. Do not assume because the one switch you are working on is powered off, that the others will necessarily be. Especially if you work with 3 way switches installed in multiple locations. This is where the contact-less voltage detector comes handy!!!I used Leviton wall plates to replace my originally installed one, which did not fit a mix of HUBBELL and TP-Link switches.If you want to install smart switches in a “shadow” area of your home, I recommend that you use a “mesh” system, rather than “repeaters or extenders”; Google, Linksys, Netgear, Samsung, eero propose equipment that eliminate any network shadow in your house. However, those are not cheap.I have tried the Linksys Velop and returned it. Each time you lose power, you need to reconfigure it.I live in an area where power outages are frequent. I am talking about losing power once every two months in average. This is why I am reluctant to equip my house with more TP-Link switches.

Easy wiring, easy wi-fi connection, and the product looks great after install. App is really easy to use too.I have 20+ units installed around my house, and they all work great. Motion sensor units work great, and the dimmer switches have memory, so the brightness level is always perfect.Only downside is the height of the switch. They don’t fit inside older (80’s) boxes very well.*** Just don’t buy used switches ***Often they come damaged, or the incorrect switch is in the wrong box. Not worth the hassle of a few dollars.

I have purchased a few TP-Link/Kasa products over the years and they have yet to let me down.These switches do exactly what you would expect and at a reasonable price and they work flawlessly.Installation was easy with the instructions provided (they even include little label stickers to wrap around the wires to make keeping track of them easier) and, once all of the wiring was done, setup took no more than a couple of minutes (including adding to Google Home for automation).Very happy with this product.
