Smart Outlets, Power Strips & Outdoor Plugs

In-Wall Smart Outlets: A Permanent, Clean Solution

While smart plugs sit between your outlet and your device, an in-wall smart outlet (also called a smart receptacle) replaces the entire outlet. From the outside, it looks just like a standard duplex receptacle, but one or both of its sockets can be controlled remotely. This is the cleanest solution for permanent installations because there is nothing protruding from the wall, no adapter blocking adjacent outlets, and no visible indication that the outlet is "smart" aside from a tiny LED indicator.

In-wall smart outlets are wired into your home's electrical system the same way a standard outlet is. Installation requires turning off the breaker, disconnecting the old outlet, connecting the hot, neutral, and ground wires to the new smart outlet, and mounting it in the box. The process is simpler than installing a smart switch because outlets have a more straightforward wiring configuration. Most smart outlets provide one always-on socket and one controllable socket, which is ideal for situations where you want one device permanently powered and another on a schedule or automation.

Good options in this category include the Leviton Decora Smart Wi-Fi Tamper-Resistant Outlet (D215R) and the TP-Link Kasa Smart Wi-Fi Outlet (KP200). Both require a neutral wire, connect over Wi-Fi, and support scheduling and voice control through Alexa and Google Home.

Smart Power Strips: Multiple Devices, Individual Control

A smart power strip takes the concept of a smart plug and multiplies it. Instead of controlling one device, you get a strip with multiple outlets, each of which can be controlled independently. This is incredibly useful behind an entertainment center, computer desk, or anywhere you have a cluster of devices that you want to manage individually.

The TP-Link Kasa KP303 is one of the most popular smart power strips. It features three individually controllable outlets plus two USB charging ports. Through the Kasa app or voice commands, you can turn off your TV and soundbar while leaving your streaming stick powered on, or shut down your monitor and desk lamp while keeping your router always on. You can set different schedules for each outlet, create groups, and monitor total energy usage.

The Eve Energy Strip is a premium option for Apple and Matter households. It provides three individually controllable outlets with Thread connectivity, meaning it works locally without cloud dependency. Each outlet reports its own power consumption, so you can see exactly how much energy your TV, game console, and sound system draw individually. Thread mesh networking ensures fast, reliable communication.

When choosing a smart power strip, look for these features:

• Individual outlet control – This is the whole point. Make sure each outlet can be switched independently, not just the strip as a whole.
• USB ports – Many strips include USB-A ports for charging phones and tablets. Some newer models include USB-C ports as well. These USB ports are often always-on and not individually controllable.
• Surge protection – A power strip that also provides surge protection saves you from needing a separate surge protector. Check the joule rating: higher is better, with 1,000 joules or more being a reasonable minimum for protecting electronics.
• Cord length – Make sure the cord is long enough to reach from your outlet to where the strip will sit. Most smart power strips come with a 4- to 6-foot cord.

Outdoor Smart Plugs: Weather-Resistant Control

Outdoor smart plugs are designed to withstand rain, snow, humidity, and temperature extremes. They are essential for controlling landscape lighting, patio string lights, holiday decorations, water features, and pool or pond pumps. An outdoor plug installs the same way as an indoor plug: you plug it into an outdoor GFCI outlet and connect it to your network.

The key specification for outdoor plugs is the IP (Ingress Protection) rating, which tells you how well the plug resists dust and water:

• IP44 – Protected against splashing water from any direction. Suitable for covered porches and patios where the plug is not directly exposed to rain.
• IP64 – Dust-tight and protected against splashing water. Good for semi-exposed locations.
• IP65 – Dust-tight and protected against water jets from any direction. This is the standard for fully exposed outdoor installations and the rating you should look for if the plug will be in an uncovered location.

Most outdoor smart plugs feature two independently controllable outlets, a heavy-duty housing with a protective cover, and a short power cord designed to connect to an outdoor GFCI receptacle.

The TP-Link Kasa EP40A is a reliable outdoor Wi-Fi plug with two individually controllable outlets, IP65 weather resistance, and built-in energy monitoring. It works with Alexa and Google Home and the Kasa app provides sunset/sunrise scheduling, which is perfect for landscape lighting. The Meross MSS620 is a more affordable alternative with similar features and HomeKit compatibility, making it a good choice for Apple households.

Outdoor plugs are especially popular for holiday lighting because you can set them on a schedule from Thanksgiving through New Year's and never crawl behind the bushes to manually plug and unplug lights again. Set them to turn on at sunset and off at 11 PM, and your holiday display runs itself all season.

Heavy-Duty Plugs for High-Draw Appliances

Standard smart plugs are rated for 15 amps at 120 volts, which handles most household devices. But some appliances draw more power and need a heavy-duty plug rated for higher amperages.

Window air conditioners, portable heaters rated above 1,500 watts, dehumidifiers, and certain power tools can approach or exceed the 15-amp limit. For these, look for plugs explicitly rated for 20 amps, such as the Zooz ZEN15 Z-Wave Plus Power Switch, which handles up to 15 amps but includes robust energy monitoring and is designed for appliance-level loads. For truly high-draw applications, dedicated 20-amp smart plugs exist from brands like Heavy Power and BN-Link.

For 240-volt appliances like electric vehicle chargers, dryers, or well pumps, smart plugs in the traditional sense do not exist at the consumer level. Instead, you would use a smart circuit breaker or a dedicated smart EV charger with built-in connectivity. Some whole-home energy monitoring systems can also control 240-volt circuits through add-on relay modules.

Organizing and Naming Your Smart Devices

Once you have more than a handful of smart plugs, outlets, and power strips, a consistent naming convention becomes essential for keeping things manageable. When you say "Alexa, turn off the lamp," you need to be sure which lamp you mean, and so does Alexa.

The most widely recommended naming convention follows the pattern "Room - Device": Living Room Lamp, Kitchen Coffee Maker, Patio String Lights, Bedroom Fan. This works well with voice assistants because you can say "turn off living room lamp" and the assistant knows exactly what you mean. Avoid names that sound too similar to each other or that include the word "light" for non-lighting devices, which can confuse voice assistants.

If you have a smart power strip behind your entertainment center, name each outlet after the device plugged into it: "Living Room TV," "Living Room Soundbar," "Living Room Game Console." This way, you can say "turn off the living room TV" and only the TV loses power, while the soundbar and game console stay on.

Group related devices into rooms within your smart home app. Most platforms (Alexa, Google Home, Apple Home, SmartThings) let you assign devices to rooms and then control the entire room at once. "Turn off the living room" shuts down every device assigned to that room. This layered approach, individual device names combined with room groupings, gives you both precision and convenience.

Spend five minutes naming and organizing each device properly when you first set it up. It saves exponentially more time later when you have 20, 30, or 50 smart devices and need to find the right one quickly in your app or troubleshoot an automation. In the next lesson, we will look at energy monitoring, one of the most practical and money-saving features available in smart plugs and switches.
