These smart plugs really do track how much power each outlet uses, so you can see watt-hours and cost instead of guessing where your energy bill is going. From Matter-over-Thread options like Eve Energy to classic Wi-Fi and Zigbee picks, you can match the plug to your ecosystem and finally hunt down those vampire loads. Keep reading to find the plug that fits your setup and helps cut your power use.
TP-Link Tapo Smart Wi-Fi Outdoor Plug with Matter
The TP-Link Tapo Smart Wi-Fi Outdoor Plug with Matter (Tapo P400M) is an IP65-rated outdoor plug with two individually controlled outlets, making it a solid pick if you want to track and tame energy use outside. Because it speaks Matter over Wi-Fi, you can bring those two outlets into Apple Home, Alexa, Google Home, or SmartThings and then watch and control each load from whichever hub you actually use. That makes it handy for spotting vampire loads like always-on patio heaters or decorative lights, then setting tighter schedules or timers to cut their runtime.This plug is built for real-world yards, with an IP65 rating, temperature tolerance from about -4 to 122°F, and dual antennas that can keep a signal up to about 300 feet in the open or through multiple walls. For an energy-focused setup, you can tie each outlet into automations in your main hub or the Tapo app, so string lights only run when someone is home or pumps only run during off-peak hours. Matter’s multi-admin support also lets everyone in the house control it from their platform of choice, which keeps your energy-saving routines from breaking if one person prefers Siri and another uses Alexa.
Kasa Smart Plug KP125M (2-Pack)
Kasa Smart Plug KP125M (2-Pack) is the “default” Matter smart plug for most people who want both remote control and real energy monitoring in a simple wall plug. Each KP125M reports energy use over time, so you can see exactly how many watt-hours that space heater, gaming PC, or coffee maker is pulling and hunt down vampire loads. The plugs connect over Wi‑Fi and speak Matter, so they slot into Apple Home, Alexa, Google Home, and SmartThings without forcing you into one brand app forever.Because the KP125M is Matter over Wi‑Fi, it works well in homes that already lean on Wi‑Fi gear and may not have a Thread or Zigbee hub. Once you set them up, the plugs can still talk to other Matter devices on your local network even if the internet goes out, which is helpful for automations like “turn off office gear after midnight.” The compact, UL‑listed, flame‑retardant shell keeps the second outlet free, and with a 2‑pack you can dedicate one to always‑on stuff like a freezer while using the other for short‑run loads to dial in your solar payback math.
TP-Link Tapo Smart Plug Mini P125M (3-Pack)
The TP-Link Tapo Smart Plug Mini P125M (3-Pack) is a compact Matter-over-Wi-Fi smart plug option that fits neatly into a home where you want per-outlet control without blocking the second socket. Each plug speaks Matter over Wi-Fi, so it can slot into Apple Home, Alexa, Google Home, or SmartThings while still reporting usage back through whatever hub or app you prefer. That makes it a nice pick if you want to track which lamps or fans are sipping power and cut down on vampire loads without committing to one brand’s ecosystem.For smart-home enthusiasts already running mixed platforms, Matter support means these P125M plugs can sit alongside other brands and still respond to the same automations and energy scenes. The compact, UL flame-retardant design works well for crowded outlets, while app and voice control let you put small appliances on schedules or timers to avoid leaving them on all day. Setup is quick with Bluetooth onboarding, so dropping a 3-pack into problem spots like the TV stand, office gear, and bedroom chargers is an easy way to start getting real numbers on what each outlet is doing.
Tapo Smart Plug In-Wall Outlet (P210M)
The Tapo Smart Plug In-Wall Outlet (P210M) is a Matter-certified, hardwired outlet that replaces your existing receptacle and adds full energy monitoring across both outlets. Instead of a chunky plug-in adapter, you get a clean in-wall install that still lets you control two outlets independently from the Tapo app or your smart home hub. It tracks power use and can estimate electricity cost for whatever is plugged in, which is great for spotting vampire loads from things like TVs, game consoles, or chargers that sit idle all day. Each outlet is rated for 15A on 125V, so it can handle typical home gear like space heaters, dehumidifiers, or window AC units you want to watch closely.Because the P210M speaks Matter over Wi-Fi, it can join Apple Home, Alexa, Google Home, or SmartThings and report watt-hours back to your preferred ecosystem. That makes it a strong fit if you want room-by-room energy data without stacking a bunch of pass-through plugs on the wall. The outlet also has features like overcharge prevention that auto-shut off outlets when a device is fully charged, plus away mode to randomly switch lights for security. If you are doing solar payback math or just tracking which always-on devices are costing you the most, this is one of the few in-wall options that gives you outlet-level energy data right in your hub.
Eve Energy Smart Plug (Matter), 2-Pack
Eve Energy Smart Plug (Matter), 2-Pack is the go-to pick here for Apple Home fans who want real energy data over Thread instead of Wi-Fi. Each plug speaks Matter over Thread, so if you already have a Thread border router in something like a newer Apple TV or HomePod, you get low-power, low-lag control without loading up your Wi-Fi network. The plug reports actual energy use, so you can spot vampire loads from things like chargers, speakers, or set-top boxes and decide what to kill or schedule.Because it talks Matter, Eve Energy can also slot into platforms like SmartThings or Home Assistant that are using Matter bridges, not just Apple Home. The compact body fits a standard outlet without blocking the second socket, which makes it easier to spread these around for whole-room energy tracking. This 2-pack is a good way to start mapping watt-hours per outlet so you can do things like track how much that always-on networking gear or TV setup really costs to run every month.
Legrand Radiant Wi‑Fi Matter Smart Plug
Legrand Radiant Wi‑Fi Matter Smart Plug (ASIN B0CLVSV67L) is the “nice to look at” option for tracking outlet‑level energy in a room where you care what the hardware looks like. It uses Matter over Wi‑Fi, so you still need a Matter controller in your setup, just like with other Matter‑over‑Wi‑Fi plugs. Once it is paired, you can see how many watts and watt‑hours a lamp, space heater, or charger is actually pulling and start hunting down vampire loads without sticking a chunky white brick on your wall.Because this plug talks Matter over Wi‑Fi, it slots into Apple Home, Alexa, SmartThings, or Home Assistant through your existing Matter hub, instead of forcing you into a separate Wi‑Fi app long term. That makes it a nice fit if you want energy data per outlet but also care that the plug matches Legrand Radiant switches and outlets you might already have in the room.
SONOFF S31 Smart Plug 4-Pack
SONOFF S31 Wi-Fi Smart Plug 4-pack is the budget pick for people who still want per-outlet energy monitoring without paying Matter prices. Each S31 reports real-time wattage and cumulative kWh, so it is handy for hunting vampire loads on TVs, chargers, and game consoles. The 4-pack keeps the price per plug low, which makes it easier to cover a whole room or power strip instead of just one problem device.These plugs connect over 2.4 GHz Wi-Fi and work with Alexa, Google Assistant, and Home Assistant, but they do not support Matter. That means they are a better fit for Wi-Fi-first homes or Home Assistant users who are fine staying outside the Matter world and just want solid energy numbers. Drop one on a fridge, dehumidifier, or space heater to log kWh over a few weeks and you can start to see which appliances are worth unplugging or upgrading.
THIRDREALITY ZigBee Smart Plug 4 Pack
THIRDREALITY ZigBee Smart Plug 4 Pack is the Zigbee pick for people running hubs like Home Assistant, SmartThings, Hubitat, or compatible Echo devices who want real-time energy data on each outlet. Each plug supports up to a 15A load, reports power use back to your Zigbee hub, and is ETL certified, so it fits common household circuits. This set is a strong fit if you already committed to Zigbee and want to track which appliances are sipping power all day for better “vampire load” hunting.These THIRDREALITY plugs work as Zigbee repeaters, so they help strengthen your mesh network while they watch your fridge, dehumidifier, or networking gear. You do need a Zigbee hub to use them, and they are not Matter or Wi-Fi plugs, so they are aimed at people who already know they want a Zigbee setup. Once paired, they can feed watt and watt-hour data into dashboards in Home Assistant or SmartThings so you can do things like alert if your freezer stops drawing power or track payback on a small solar setup.
Summary
The right energy-monitoring smart plug depends on your existing ecosystem: Matter-over-Thread (Eve Energy) for Apple Home, Matter-over-Wi-Fi (Kasa KP125M, the Tapo plugs, Legrand Radiant) for mixed setups, and Wi-Fi-only (SONOFF S31) or Zigbee (THIRDREALITY) when you don’t need Matter. Start with a few plugs on always-on loads — fridges, networking gear, entertainment centers — and let the data tell you where the waste actually lives.
