I've used a lot of smart home gadgets, and often the "easy setup" promised on the box turns into a frustrating session of troubleshooting. The Kasa Smart Plug HS103P4, however, is the rare exception. It lives up to its name by being incredibly easy to get up and running, especially with the ecosystems that matter most to me: SmartThings and Alexa. The initial setup with the Kasa app itself was a breeze. I had all four plugs connected to my Wi-Fi in a matter of minutes. The app guides you through the process step-by-step, and it just worked flawlessly, with no unexpected connection drops or firmware issues. But the real magic happened when I linked it to my smart home hubs. For Alexa, it was as simple as enabling the Kasa skill and letting it discover the new devices. Within seconds, I was using voice commands to turn my lights and appliances on and off. The response time is instantaneous, and the reliability has been perfect—Alexa has never failed to control a Kasa plug. Integrating with SmartThings was equally painless. The connection process was straightforward, and the plugs appeared in my SmartThings app with all the functionality I needed. This has allowed me to incorporate them into more complex automations, like having a lamp turn on automatically when I open the door. In a market full of smart plugs that can be a headache to install, the Kasa HS103P4 stands out as a dependable, user-friendly choice. If you're looking for a plug that plays well with Alexa or SmartThings and won't leave you frustrated, this is the one to get.

If you need a timer for whatever reason, these are the best. I have so many of these and I use them all over our home for turning lights on and off. Well of course that's what they're for, right? Ever set up a Christmas tree, get it plugged in and then when it was bedtime you struggled to reach the outlet to unplug those lights? I know I have. Sure, you can buy one of those step on switches that you plug your light strings into. But these make it so much easier to control and setup. There's a small learning curve to get it loaded onto your home internet, but once you've done one the rest are a breeze. Yup, your internet. No it's not going to slow it down and no it's not going to create issues with other wifi connected devices. In my home, I use not only these outlets, but I also use the wall switches, both single and three way switches. Also use the outlets that are meant for being outside in the weather from this same company. And they all work perfectly. Just to give you an idea I have at one time, mainly during the Holidays, I have at least 15 of these outlets around inside my home. Add into that 4 wall switches and another 4 outdoor weather resistant plugs. Take all those along with laptops, phones, speakers, tv's, tablets and I forget what else and I have zero issues with my 500GB internet speed. As for the plugs, they connect to your internet quickly, easily, install the app on your phone, laptop, tablet whatever to set them up and your good to go. Program them anyway you need, on at dusk, off at dawn, on or off at any time of day or night any number of days you want, and they work flawlessly. The outlets I have outside work no matter the weather, they're just as durable as you need. We have one that's located 60-70 feet outside, from our home and we can easily control it from inside our house. Did you leave the house and leave something plugged into a timer you didn't really want to have come on when you're not home? Just go into the app and turn it off, from wherever you are. Honestly I can't say enough good things about these plugs. The only scary part is when you have several of them scheduled to turn on at one certain time, like say dusk and all of sudden you're walking around and click, click, click, lights are coming on everywhere. Oh, and if your internet goes down, you won't have control of them through the app. But you can walk up to any plug, push the button on the side and it'll turn on or push the toggle on the light switch it'll still turn on. And they don't lose their programing, if the internet's not available, they will still turn on and off just as though they were connected to the internet. Then when your internet connection returns, they automatically reconnect, just like any other device you might have.

These Kasa smart plugs are easy to setup, and they work great. They reconnect to your wifi automatically if you ever unplug them or loose power to your house.

I bought these to replace another smart wi-fi outlet that had failed. I've bought these before and they are easy to setup using the Kasa app and then integrate into my Amazon Alexa smart home. They are a quality product and a their size allows you to use two, one in each socket in a normal wall outlet.

These have 2 pairing options. WIFI and Bluetooth. WIFI does not work 80% of the time. Recommend you use Bluetooth to pair and program. Other than that, these work great.

I love these plugs. Easy to install, easier to use. So easy a 5 year old can use them. Plus Kasa offers free technical support 24/7. I Love this company. I spoke with a tech by the name of Jolina and she answered all my questions and had me up and running in no time. She was wonderful!!!!!

These smart plugs are an amazing addition to my Home Assistant automation. They work fabulously and I will be getting more of them in the future. These little things work exactly as advertised and I couldn't be happier. The app is easy to use and full Matter compatibility means I have zero issues integrating it into my life. Unlike other smart plugs, you can two into one outlet or have one smart and one "dumb" plug.

Never fail, always work. Unlike the Kasa smart led bulbs which I have thrown away 19 bulbs that stopped connecting and after endless attempts would not discover or connect. The app is lame and not user friendly. Amazed at how all of the bulbs failed. I replaced with DayBetter bulbs whose app is quick and bam connects. The bulbs lasted a year to a year and a half. Every one stopped connecting. Try like 8 times on one bulb. Can’t find server! Lame! In the garbage
