We tested smart plugs that actually track energy usage. The Emporia Classic leads for real-time and historical monitoring, with Matter and outdoor alternatives for specific needs.
Your home is full of devices that quietly sip power — phone chargers, entertainment centers, old TVs on standby. These "energy vampires" can add 10–20% to your monthly bill without you noticing. A smart plug with energy monitoring is the cheapest way to find them, measure them, and schedule them off.
We looked at real-time tracking depth, historical logging, app quality, and ecosystem compatibility to find the plugs that actually help you save.
emporia classic. If you want detailed, actionable energy data, this is the one. The Emporia app shows real-time wattage, daily and monthly kWh totals, and estimated cost — all without a subscription. You can see exactly what each connected device is doing and set schedules to cut usage during peak hours.1 It works with Alexa and Google Assistant, handles a full 15A load, and costs less than most plugs that offer far less data.
why it wins: Real-time + historical energy tracking, peak-hour scheduling, 15A rating, and no subscription fees. The app is clean and the data is granular enough to actually change your behavior.
tp-link tapo p110m (matter). If you want Matter compatibility for future-proofing your smart home, the P110M is the top pick. It offers energy monitoring, works with Alexa, Google, and Apple Home via Matter, and is widely reviewed as the best overall smart plug for 2025.2 The Tapo app logs daily and monthly energy usage, and you can set schedules and away modes.
kasa smart outdoor plug kp401. For outdoor energy monitoring — holiday lights, pond pumps, patio heaters — the Kasa KP401 is a weather-resistant dual-outlet plug. It handles 15A and works with Alexa and Google. Note that outdoor-focused models may have less granular energy reporting than indoor counterparts, so check the app's monitoring depth for your use case.
minoston matter outdoor smart plug mp22m. A Matter-enabled outdoor plug that brings future-proof connectivity to heavy outdoor equipment. It supports 15A loads, works across Alexa, Google, and Apple Home via Matter, and is built for all-weather use. If you're building a Matter-based smart home and need outdoor energy control, this is the one to get.
| feature | emporia classic | tp-link tapo p110m | kasa kp401 | minoston mp22m |
|---|---|---|---|---|
| energy tracking | real-time + historical | real-time + daily/monthly | basic | basic |
| ecosystem | alexa, google | alexa, google, apple (matter) | alexa, google | alexa, google, apple (matter) |
| form factor | indoor | indoor | outdoor (weather-resistant) | outdoor (weather-resistant) |
| amp rating | 15A | 15A | 15A | 15A |
energy tracking depth. Not all "energy monitoring" plugs are equal. Some show only real-time wattage; others log historical data you can review in charts. The Emporia Classic and Tapo P110M offer the best logging for actually tracking trends over time.1
ecosystem compatibility. If you're all-in on Apple Home, look for Matter or HomeKit support. Alexa and Google are more universal. Matter is the emerging standard that lets you switch platforms later.
amp rating. Most major appliances need a 15A-rated plug. Lower-rated plugs (10A) can't handle space heaters, window ACs, or high-wattage kitchen gadgets. All our picks are 15A.
form factor. Outdoor plugs need weather-resistant housings and ground prongs. Indoor plugs are smaller and often block adjacent outlets less.
The Emporia Classic is the best smart plug for anyone serious about tracking and reducing energy usage. If you need Matter compatibility, the Tapo P110M is an excellent alternative. For outdoor use, choose the Kasa KP401 or Minoston MP22M based on whether you need Matter.
