Kasa Matter Smart Plug with Energy Monitoring, 4-Pack (KP125M)
The KP125M is built on Matter, the cross-platform smart home standard that eliminates compatibility guessing between ecosystems. Setup works natively through Apple Home, Alexa, Google Home, or Samsung SmartThings without requiring the Kasa app as an intermediary. Energy monitoring tracks real-time and historical power consumption per outlet — practical for identifying which devices draw standby power and for building shutoff automations based on actual usage data. The compact design leaves the second outlet on a standard two-outlet receptacle unblocked, which matters in a plug that stays installed permanently. The 15A/1800W rating handles most household appliances including space heaters and small window AC units. The four-pack configuration makes it practical to equip multiple outlets at once. For households building a smart home on current standards, the Matter compatibility means these will keep working as ecosystems evolve.
