Matter-certified smart plug with real-time energy monitoring that works with every voice assistant

Kasa EP25: The Matter smart plug that monitors energy and works with everything

The Kasa EP25 hits the right intersection: it uses the Matter protocol (meaning it connects to Alexa, Google Home, Apple HomeKit, SmartThings, and any other Matter controller simultaneously), and it includes real-time energy monitoring that shows exactly how much power a device is drawing. At $22, it's the safest buy in the category.

What works

Matter certification is the key differentiator. Unlike WiFi-only plugs locked to one ecosystem, the EP25 registers once and is visible everywhere. If you switch from Alexa to Google Home, or add a Home app to your setup, the plug moves with you without re-pairing. For a smart home component you'll use for years, that flexibility is worth paying for.

Energy monitoring shows real-time wattage and cumulative kWh with a monthly cost estimate. Useful for understanding how much a space heater, dehumidifier, or refrigerator actually costs to run. The Kasa app also supports schedules, countdowns, and away mode.

At 15A and 1800W max load, it handles any standard household appliance. The form factor is slightly larger than a standard plug but leaves the adjacent outlet clear on most outlet configurations.

What doesn't

Like virtually all WiFi-based smart plugs, the EP25 requires a 2.4GHz network — it will not connect to 5GHz-only networks or 5GHz bands on dual-band routers without splitting the network. This is a one-time setup annoyance rather than an ongoing limitation.

Who should buy this

Anyone setting up a smart home who wants energy monitoring and doesn't want to commit to a single voice assistant ecosystem. The Matter standard guarantees this plug works regardless of which direction the smart home market moves.

Who should look elsewhere

Apple HomeKit only, no energy monitoring needed: Wemo Mini 2nd Gen ($35). Budget energy monitoring with simpler ecosystem: Emporia Smart Plug ($20). Ultra-compact form factor: TP-Link KP125M ($18).
