Best outdoor smart plugs

Whether it’s for holiday lighting — or any time of year — picking up one of the best outdoor smart plugs will make wiring up all of your decorations and outdoor lights that much easier. An outdoor smart plug lets you control your outdoor lights via your smartphone, set schedules, and even sync them to other smart home devices.

For instance, an outdoor smart plug can turn on your lights if a motion sensor detects something running across your yard, or when you return home from a night out.

Or, you can just set your outdoor smart plug to turn on your lights as it gets dark, and turn them off in the morning. Whatever your purpose, an outdoor smart plug is an inexpensive, yet handy smart home gadget, especially if you've decided to learn how to grow a Christmas tree and you want to put it outside yet still have it lit up. 

What are the best outdoor smart plugs?

After testing a handful of devices, we think the Wyze Plug Outdoor is the best outdoor smart plug around. It’s relatively compact, has two outlets which can be controlled independently, and its app has a lot of scheduling options, even letting you connect it with other Wyze products. Best of all, it costs less than $20.

Most of the other smart plugs we tested were all very good, but all had one thing or another that just wasn’t right. Some didn’t have sunrise/sunset settings in their apps — very useful for outdoor smart lights; another has two plugs, but you can’t control them separately. Yet another has four plugs, but no way to turn them on or off on the device itself. 

Read on to see what we liked and didn’t like about the best outdoor smart plugs.

1. Wyze Plug Outdoor

Best smart outdoor plug overall

Specifications
Weather resistance: IP64
Size: 3.9 x 2.7 x 1.4 inches
Outlets: 2
Works With: Alexa, Google Assistant
Electrical rating: 15A
Wireless: Wi-Fi (2.4GHz)
Reasons to buy
+Inexpensive+Controls two outlets separately+Good scheduling features in app
Reasons to avoid
-Power cord harder to fit into electrical box

Wyze has built a reputation on making good low-cost smart home devices, and the Wyze Plug Outdoor is another such product. Like most outdoor smart plugs, the Wyze Plug Outdoor is a black box, with a cord on one end and two outlets on the other. The cord is a little short at around 6 inches, and the plug is in-line with the cord, so it was tough to cram it into my outdoor outlet and close the cover. 

The Wyze Plug has two sockets; at the top of the front of the Plug are two buttons to control each socket, with small LEDs that show which is active. Just below the buttons is a small light sensor; this can be used to tell the outlet when to turn on or off, based on the ambient lighting conditions. 

However, you can also create a schedule based on a set time of day, as well as sunrise and sunset — though there’s no offset, such as 15 minutes before or after sunrise. You can also use other Wyze products as triggers  — for example, having the plug turn on a light if a Wyze Cam detects motion. These too, can be time-based, but you can’t specify if something should work only after it gets dark out. 

You can also set a vacation mode, where the Plug will turn on and off so it looks like you’re home, but I’m not sure how useful that is for an outdoor light. As of this writing, the Wyze Plug Outdoor works with Alexa, but not Google Home.

One of the best outdoor smart plugs for scheduling

Specifications
Works with: Alexa, Google Assistant, SmartThings, IFTTT
Wireless: Wi-Fi (2.4 GHz)
Water resistance: IP64
Power rating: 1875W/15A
Size: 4.9 x 2.4 x 2.3 inches
Outlets: 2
Reasons to buy
+Two outlets+Comprehensive app
Reasons to avoid
-Lacks two-factor authentication

TP-Link's Kasa Smart Outdoor Plug KP400 has two outlets, so you can control two devices independently. The plug is a substantial 4.9 x 2.4 x 2.3 inches, but housed inside its thick plastic housing is a Wi-Fi radio that should connect to your router from up to 300 feet away. The KP400 is IP64-rated, so it can withstand dust and most rainfall, but you should ensure that the outlets are facing downward and covered when not in use. 

Aside from the hardware, it's TP-Link's Kasa app that sets this device apart from other smart outlets. The app makes the setup process exceedingly simple; it works with Alexa, Google Assistant, SmartThings and IFTTT, and it has pretty good scheduling options for letting you turn your lights on and off at certain times — including sunset and sunrise. There’s even an offset if you want the lights to turn off at a set time before sunrise, or on before sunset. The app also lets you create scenes and automations to work with other Kasa devices. However, Kasa’s app still lacks two-factor authentication. 

Ring smart plug

3. Ring Outdoor Smart Plug

The best outdoor smart plug for Ring owners

Specifications
Size: 4.9 x 3 x 2 inches
Plugs: 2
Works With: Ring, Alexa
Electrical rating: 15A/1875W
Water resistance: IP64
Reasons to buy
+Relatively inexpensive+Has two outlets
Reasons to avoid
-On the large side-Needs to connect to hub

The Ring Outdoor smart plug is a massive brick. At the bottom are two plugs, each protected by a rubber flap. At the top is a 6.5-inch cord that’s long enough to plug the Ring into an outdoor outlet, while still being able to close your outlet’s door. I especially like that the prongs are at a right angle to the cord; it makes it much easier to close the door.

The Ring also comes with three screws and wall anchors.  On the front of the Ring is a large circular button that’s blue in the center; you can press on either side of the button to control each outlet independently. The button makes a slight clicking sound. 

Unlike most other smart plugs, the Ring needs to connect to a hub, which can either be a Ring Bridge ($49) or an Amazon Echo smart speaker. Within the Ring app, you can configure the two outlets to work together or separately, and create schedules for when it turns on and off. In all, the Ring Outdoor Smart Plug is a good device for those invested in the Ring ecosystem.

Best outdoor smart plug for dimming

Specifications
Works with: Alexa, Google Assistant, SmartThings, IFTTT
Wireless: Wi-Fi (2.4GHz)
Water resistance: IP64
Power rating: 300W Incandescent, 150W LED/CFL
Size: 3.1 x 2.8 x 1.5 inches
Outlets: 1
Reasons to buy
+Lets you dim lights+Robust in-app features
Reasons to avoid
-Only one plug-No two-factor authentication

One of the problems with most smart outdoor plugs is that they lack a dimming function. The Kasa Smart Wi-Fi Outdoor Dimmer lets you do, well, exactly that — dim whatever lights are connected to it. It’s great if you want to create even greater ambiance in your outdoor space. Keep in mind that not all lights will react the same to being dimmed — some may flicker. 

The Kasa app has a ton of features, from scheduling to connecting the plug to other TP-Link smart home devices, to controlling it with Alexa, Google Assistant, and SmartThings. However, like TP-Link’s other outdoor plug — as well as all of its other smart home devices — the Kasa app lacks two-factor authentication, which makes it easier for hackers to potentially break into your account and take control of your smart home devices. 

GE Smart plug

5. GE Lighting Cync Outdoor Smart Plug

A well-designed outdoor smart plug but a simplistic app

Specifications
Works with: Alexa, Google Assistant
Wireless: Wi-Fi (2.4GHz)
Water resistance: IP64
Power rating: 15A
Size: 5.3 x 2.7 x 2.6
Outlets: 2
Reasons to buy
+Two plugs+Prongs perpendicular to cord+Great design
Reasons to avoid
-Simplistic app-App lacks two-factor authentication

GE’s outdoor smart plug looks like a more bulbous version of the TP-Link KAsa 400. We like that the prongs on the GE plug are perpendicular to the 7-inch cord; the prongs are slightly angled, too, so you can fit more than one in a standard outlet. Two soft rubber flaps help protect the outlets when they’re not in use. Above each outlet is a small button to control each independently, with two small LEDs indicating their status.

GE’s app is intuitive — icons are large, bright, and instructions easy to follow — but it’s a bit simplistic. You can create schedules for the plugs to turn on and off at scheduled times, but there’s no sunrise or sunset option, for instance (you could do this with Alexa, but that’s a separate step). It also lacks two-factor authentication, and I found the app crashed on me while I was using it on an iPhone running iOS 15. And, while it works with Alexa and Google Assistant, it’s not compatible with Siri.

PowerUI smart plug

6. POWRUI Smart Power Strip

The best outdoor smart plug if you have a lot of lights

Specifications
Works with: Alexa, Google Assistant, IFTTT
Wireless: Wi-Fi (2.4GHz)
Water resistance: IP44
Power rating: 1875W/15A
Size: 5.8 x 5.7 x 1.3 inches
Outlets: 4
Reasons to buy
+Lets you control up to four devices separately+Well-designed app
Reasons to avoid
-No physical power buttons on plug-Basic in-app features

The PowrUI Smart Power Strip is built for those Clark Griswold types who have a lot of outdoor smart lights, and not enough outlets. Extending from the body of the PowrUI are four plugs, all of which can be controlled independently. Annoyingly, though, it all has to be done through the generically named Smart Life app (available for Android and iOS). That’s because the only button on the smart plug itself turns off all four plugs. A green LED above each plug indicates whether it’s on or off.

The Smart Life app is generally well-designed, but pretty basic. You can rename each plug, set a countdown timer, and create schedules for each plug to turn on and off, but there’s no sunrise or sunset setting. However, the plugs can also be controlled via Alexa or Google Assistant, so you can use those assistants.

Wemo smart plug

7. WeMo WiFi Smart Outdoor Plug (WSP090)

Works with HomeKit

Specifications
Works with: Alexa, Google Assistant, HomeKit
Wireless: Wi-Fi (2.4GHz)
Water resistance: IP44
Power rating: 1800W/15A
Size: 3.7 x 3.5 x 1.8 inches
Outlets: 2
Reasons to buy
+Two plugs+Prongs perpendicular to cord+Robust app features
Reasons to avoid
-Can’t control each outlet separately

While the WeMo’s prongs are perpendicular to the cord, they’re not angled like the GE Cync plug, so it may be more difficult to fit two to an outlet. It’s not the most attractive, but it gets the job done. With an IP44 rating, it’s a little more susceptible to rain than other plugs, but it has covers for both outlets. However, the dumbest thing about WeMo’s smart plug is that while it has two outlets, you can’t control them separately. 

Fortunately, WeMo’s app is pretty robust. In addition to scheduling — including sunrise and sunset offsets — it has an Away mode, which, when set, will turn your lights on and off randomly to make it look like you’re home. While less applicable for outdoor lights, it’s a good feature for indoor smart plugs. And, not only does WeMo’s plug work with Alexa and Google Assistant, but it’s also compatible with HomeKit — the only outdoor smart plug on this list with that ability. If it had the ability to control each outlet separately, this would be darn near perfect.

Lutron Caseta smart plug

8. Lutron PD-15OUT-BL Outdoor Smart Plug

A pricey outdoor smart plug for Lutron Caseta owners

Specifications
Works with: Alexa, Google Assistant, HomeKit
Wireless: Lutron bridge
Water resistance: IP65
Power rating: 15A
Outlets: 1
Reasons to buy
+Robust app with lots of features+Works with all three virtual assistants
Reasons to avoid
-Four times as expensive as other outdoor smart plugs-Requires Lutron bridge-Very large

If you’re invested in the Lutron Caseta family of smart light switches and smart plugs, then it’s worth taking a look at its outdoor smart plug. However, its high price of $80 — four times that of other outdoor smart plugs — and the fact that it only has one plug for its massive size moves it well down our list. Lutron’s plug also makes it harder to fit into covered outlets. While the plug itself has an on/off switch, you can also pair it with a remote ($20, sold separately) if you’re looking for an easy way to control it from inside.

Similar to Ring’s outdoor smart plug, in order to control the Lutron plug from your phone or use any of its features, you need to connect it to a Lurtron bridge, which itself costs $80, and which needs to be within 30 to 60 feet of the plug. However, once connected, Lutron has a very robust app and ecosystem — you can control it with Alexa, Google Assistant, and Siri, and you can not only create schedules, but even use geofencing to have the lights turn on automatically when your phone gets within range of your house. 

What to look for when buying an outdoor smart plug

Plug orientation

Most outdoor outlets have a protective cover of some sort that shields them from the elements; some covers can close even when something is plugged in to the outlet. However, if a smart plug’s prongs are in line with its cord, then this often means that the cord will have to be bent 90 degrees in order for you to close the cover, which could lead to the smart plug wearing out sooner. 

Other smart plugs are designed so that the prongs are perpendicular to the cord, so that when you plug it into an outlet, it hangs down naturally, and won’t get bent if you plug it into an outlet. 

Number of plugs

Chances are, you’ve got more than one thing to plug in outdoors, so the better smart plugs have at least two outlets. More importantly, they let you control each outlet separately, making it much easier to control when things turn on and off.

Smart scheduling

One of the features we look for in the best outdoor smart plugs is the ability to schedule them to turn on at sunset and off at sunrise. If the lights you want to control are up all year-round, you don’t want to have to keep fiddling with the app as the days get longer and shorter. The very best apps in this regard also have an offset, so you can have your lights turn on at a set time before sunset — when it’s getting dark.

Water resistance

This should be a given, but any outdoor smart plug should be able to withstand some rain and snow. 

How we test the best outdoor smart plugs

In order to determine which are the best outdoor smart plugs, we install them outside our home, and evaluate a few key factors: 

  • How easy is it to set up? 
  • How well does it fit in our outdoor outlets? 
  • Is it a well-designed product? 
  • What features does the app have?

We take these, as well as other factors such as the price into consideration, and then compare that to competing devices to determine our final rating.
