It's 2018, and yes, I am disappointed that we don't have flying, time-traveling cars. However(!), we do have incredible smart plugs that can basically control everything in your home via an app — and that's some futuristic technology I can get behind.

Especially considering that, you know, we all have our lazy moments. Just think about that dreaded feeling of crawling into your warm, cozy bed — only to realize that the lights are *still on*! This is what true defeat looks like.

Thanks to the handy TP-Link Smart Plug (on sale for $19.99; originally $27.99), though, you can now turn electronics on and off, operate your Alexa or Google Home, and schedule the lights to go on at a certain time — all from the comfort of wherever you are. (I'll be on my couch.) 👏

And all you need to control lights, fans, humidifiers, and whatever else needs controlling on is your phone! You just download the Kasa app, and from there you can monitor everything that's connected to the smart plug. (The app is compatible with iPhone and Android.)

The smart plug and your phone use Wi-Fi to communicate with each other, so as long as you have a secured 2.4 GHz network connection, you're set.

Here's how it works:

The smart plug goes into a regular outlet and acts as the new power source. You can plug in lamps, coffee makers, fans, small appliances — whatever you're looking to control — with the app. Once that's done, you can turn them on or off, including scheduling lights to turn on in the morning or at night to give the appearance that you're home.

AND! You can pair the smart plug with your Alexa or Google Home device so it's voice-activated. It's like we're living in Disney's Smart House (just without the scary mom hologram)!

And listen: I am not the only one who thinks this is the coolest invention since the World Wide Web. The product has over 3,000 reviews and a 4.3-star average rating on Amazon.

Promising review: "I set this up on my Alexa and the app in less than 30 minutes start to finish. I noticed that sometimes I would say the command, 'Alexa, turn on lamp,' and Alexa would respond 'OK' without actually turning anything on. The issue was my five-year-old router. I replaced the router with a new one that could handle more devices. The new router resolved the issue. I've been using this plug for a few months now and it is still working great." —C. Dunn

Promising review: "These switches do NOT require a special hub to use them. So you don't have to jump through hoops to set up the hub and then jump through even more hoops to set up each switch to connect to that hub. The Kasa app on your phone lets you program timers into each switch as well as controlling them remotely. You can be on vacation and turn the lights on at your house. Lastly, the energy monitoring feature is really handy. When you look at a particular switch in the app, you get a complete picture of the energy consumed by the lights or devices hooked to that particular switch. It's an eye-opening experience to see how some items use a lot more energy than you thought, while others are pretty frugal. Lastly, the TP-Link switches, Nest thermostats/alarms, and the Echo can all work together to lower your energy costs by sensing when you're home or away. This is when the potential of integrated home automation becomes really clear. Highly recommended!" —Bill D.

The company behind these smart plugs, TP Link, also has a variety of other plugs and switches with different features.

If you're looking to control actual light switches, you can buy a three-way light switch kit, which will allow you to turn lights on/off in living rooms, stairways, and halls (on sale for $54.99).

There's also a mini version that only occupies one socket and is ideal for Christmas tree lights (on sale for $24.99).

If you're not a professional electrician, don't fret. The setup is simple and they have a tutorial-packed YouTube channel that walks you through each step.

The energy monitoring smart plug normally retails at $27.99, but thanks to the wonders of Prime Day, it's on sale for $19.99!!!!

Now you can transform your crib into a smart house. Or never again stress about whether you left your coffee pot or curling iron on. You can turn your Christmas tree lights on and off, just because. Really, you can do *whatever* you want with these smart things. It's just...too cool not to have!
