    I use this for some outside string lights and it works great. Connects well with Google assistant and the phone app is designed intuitively. I love the timer settings. This was a good purchase.

    Need to setup the Kasa mobile app first, and add the device plugs with names using the included wifi. Then within the Google Home app, add the Kasa integration. I am able to group the plugs together by room. Can either include in existing scenes or command the devices as a group. If needed, I can also voice command individually. Scenarios are endless. I setup a time based trigger to turn on at 50% brightness at sunset. They turn off as part of my goodnight scene. I also found some logic using IFTTT to only turn the lights on when I’m home. No complaints with my floor lamps now being better managed by Google Home for energy efficiency. I like the dark color of the plug and cord, as well as the additional manual dimming ability. I’m sure you can add a motion sensor for even more improvement.

    This is my third Kasa smart plug and will certainly not be my last. I now have two dual plugs and this single, dimmable, plug. I use them in our back yard to light up our fire pit, on the front porch for Christmas lights and on the deck for controlling the pool pump and other pool resources. These plugs are ultra customizable and fully integrate with Google Home (I do not use Alexa, so I cannot rate that integration). I find it best to customize them in the native Kasa app and then can control them from any of my Google Home apps or devices. The quality of the devices is also top notch and have had no issues with them being outside, fully exposed to the weather.

    Bought it to control string lights on my patio. Easy to set up.

    I have about 400 watts of outdoor lights. The plug has built in overheating protection, which is great; however at 100% brightness, our outdoor lights are too much for this plug. We had no issues plugged directly into the outlet. We have to die about 50% for this smart plug. The lights are dimmable incidents. Combined about 400watts full power.If they were LED, this might not be an issue.

    I have multiple Kasa products and used them for several years. I have not had any problems with these products and love the features. I would love to see an emergency button on the app that turns on all connected lights. This would be great to help public safety responders locate you residence or scaring away criminals.

    We recently moved to an apartment with a large balcony. This plug works perfectly with our Alexa and the lights we purchased. Love how you can control how dim or bright you want it by a command.

    Ive installed numerous TP-Link Kasa smart plugs and switches to integrate my home lighting with my Alexa Echos and Show 8 as well as my Ring doorbells and cameras. Im amazed at how well all these different systems work together. I needed an outdoor smart plug to control both some outside Christmas lights as well as a bird bath heater. This Kasa Smart K400 Outdoor Smart Plug works perfectly. Since the two outlets on the plug can be controlled independently, I plugged my heated bird bath into one and my Christmas lights into the other. I especially like the Kasa Android app, which allows you to easily set what time you want the lights to come on and go off. You can also set it to come on at Sunset (or a prescribed number of minutes before or after sunset) (similarly with Sunrise). You can set different times for each day of the week if you want. A very nice and easy to use app. Installation of the Smart Plug was also very straightforward with step-by-step guidance from the app. For my heated bird bath, I set up a routine using the If This Then That (IFTTT) app. I set the heater to turn on if the outside temperature drops below 35 deg F and turn off if the outside temp goes above 35 deg F. One thing to be aware of - the Kasa outlet must not be limited to Local control if you want outside apps such as IFTTT to work with it. For some reason, my outdoor smart plug reverted to local control and there is no obvious way to get out of this state using the app. After researching this on the web, the one solution that seemed to work was to assign the smart plug a reserved DHCP IP address on your home router. I did this and then reset the switch. All works fine now. Bottom line is this is a waterproof outdoor smart outlet that works well, has an easy to use and very flexible controlling app, and integrates nicely into the smart house ecosystem (at least with Alexa, Google Home, and IFTTT which are the ones Ive tried). I would gladly buy this again if I need another one.

    Ive tried several of the other cheaper smart plugs and its hit or miss if they work or not. I have 3 Kasa plugs including this outdoor one and they were all simple to connect (less than 5 minutes), integrate with google home and work just as I need them too. Do yourself a favor and spend a few bucks extra and get the Kasa so you dont have to deal with the headaches.
