We tested the top outdoor smart plugs with energy monitoring to help you cut electricity bills, monitor holiday lights, and catch faulty equipment early. Our picks cover Matter compatibility, multi-socket setups, and long-range Wi-Fi for every yard size.
If you've ever wondered how much power your patio string lights, pond pump, or holiday inflatables are actually drawing, an outdoor smart plug with energy monitoring is the answer. Beyond the convenience of voice control and schedules, these plugs give you real-time wattage data so you can spot a failing pump (spiking power draw), trim holiday light costs, or just prove to yourself that leaving the fountain on 24/7 costs less than you think.
But outdoor plugs face rain, snow, dust, and temperature swings — so weatherproofing matters as much as the smart features. Here are the three best outdoor smart plugs with energy monitoring, ranked by connectivity, durability, and real-world usefulness.
The Minoston MP22M is the most future-proof outdoor plug you can buy right now. It supports Matter, the universal smart home standard, which means it works natively with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings — no bridging, no compatibility headaches. 2
It's rated IP65, meaning it's fully dust-tight and protected against low-pressure water jets (think heavy rain or a garden hose splash). The enclosure handles temperatures from -4°F to 122°F, so it'll survive a Canadian winter or a Texas summer. 2
The energy monitoring is granular enough to track individual device power draw through the Minoston app, and you can set schedules or timers locally (LAN control) even if your internet goes down. The 15A / 1875W rating covers most outdoor appliances, from hedge trimmers to space heaters. 2
Specs that matter: IP65 weatherproof, Matter + Wi-Fi 2.4 GHz, 15A / 1875W, LAN control, child lock.
If you need to control more than one thing at an outlet location — say, holiday lights on one socket, a fountain pump on another, and a landscape spotlight on the third — the Meross three-socket outdoor plug is the obvious choice. Each socket is independently controllable, and the unit still carries an IP44 rating (splash-proof from any direction). 1
Energy monitoring is available per-socket in the Meross app, so you can compare the draw of each device and see exactly which one is the energy hog. It works with Alexa, Google Home, and Apple HomeKit out of the box. 1
The trade-off: IP44 is less rugged than IP65 or IP64. It'll handle rain and sprinklers fine, but you'll want to keep the plug elevated off the ground (use the included mounting bracket) and avoid direct hose blasts. For covered patios or eaves, it's perfect.
Specs that matter: 3 independently controlled sockets, IP44, HomeKit + Alexa + Google Home, per-socket energy monitoring.
The TP-Link Kasa Outdoor Plug (model EP40 or KP401 depending on generation) has a built-in power amplifier that pushes Wi-Fi range up to 300 feet in open areas. 3 If your outdoor outlet is at the far end of the yard, near a detached garage, or behind a brick wall, this is the plug that'll actually stay connected.
It's rated IP64 — fully dust-tight and protected against splashing water from any direction. That's a step above IP44 and a small step below IP65 (which adds low-pressure water jet resistance). For most residential rain and snow, IP64 is plenty. 3
The Kasa app provides real-time energy monitoring and historical usage graphs. You can set schedules, countdown timers, and "away modes" that randomize on/off patterns. It works with Alexa, Google Home, and Samsung SmartThings. 3
Specs that matter: IP64, 300ft Wi-Fi range, 15A / 1875W, Alexa + Google Home + SmartThings, energy monitoring.

Energy monitoring isn't just about saving pennies on your electric bill — it's a diagnostic tool. Here's what to watch for:
All three will save you money, catch equipment problems early, and make your outdoor space genuinely smarter.
