Kasa Matter Smart Plug with Energy Monitoring, KP125MP2, 15A/1800W Max
- 【Matter-Compatible Smart Home Integration】Works with Matter-certified platforms such as Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings. Users can manage compatible devices across supported apps within the Matter ecosystem.
- 【Matter: Smooth LAN Control】All Matter-certified devices in your local area network (LAN) will work smoothly even when your home internet goes offline. Matter allows effective communication directly between devices, without the need for a specific 'forwarding' device. For example, a Matter smart switch or sensor can turn on/off a Matter bulb directly without being connected to a cloud service, or other specific action. Once configured, communication and control between Matter devices can be achieved directly on the local network.
- 【Energy Monitoring】Tracks energy usage over time to help you understand consumption patterns and make informed decisions about how your devices are used.
- 【Compact & Flame Retardant Design】Avoid blocking additional outlets with its compact design, and plug in your WiFi smart plug with confidence thanks to its UL certified flame retardant design and 2-year limited warranty.
- 【App & Voice Control】Control your WiFi smart plug from anywhere, anytime via the free Kasa App or just give voice commands to Siri, Amazon Alexa, Google Assistant or Samsung SmartThings. Your favorite smart assistant enables you to have a truly hands-free experience.

Quick Verdict
The Kasa KP125M brings genuine future-proofing to a simple smart plug, pairing Matter certification with real energy monitoring in a compact, flame-retardant design. It works across Apple Home, Alexa, Google Home, and SmartThings without being locked into one ecosystem, and the Kasa app makes tracking device power usage straightforward. It’s slightly pricier than basic non-Matter plugs, and the energy monitoring data lives in a separate section of the app rather than being front and center, but for anyone building a genuinely cross-platform smart home, it’s a smart, forward-looking choice.

Frequently Asked Questions

No — it connects directly over Wi-Fi with Bluetooth used only for initial setup, and works as a standalone Matter-certified device without needing an additional Matter controller for basic functionality.
How accurate is the energy monitoring?
The Kasa app tracks real-time and historical power consumption per device, giving a reliable picture of usage patterns over time to help identify energy costs and inefficient appliances.
Can I mix this with older Kasa devices that aren't Matter certified?
Yes — it works alongside your existing Kasa devices through the same app, and Matter certification adds cross-platform compatibility without removing any existing Kasa ecosystem functionality.

It works seamlessly across Apple Home, Alexa, Google Home, and SmartThings, making it a smart choice for anyone who doesn’t want to be locked into a single ecosystem. It costs more than a basic smart plug, and the energy data takes a bit of digging to find in the app, but for buyers who want both cross-platform flexibility and genuine usage insights, it delivers real value.
