Side-by-Side Comparison
| Spec | Emporia Energy Monitoring Smart Plug (1-Pack) | Kasa Matter Smart Plug KP125M (KP125MP4 4-Pack) |
|---|---|---|
| Price | $11.99 | $37.93 |
| Release Year | 2022 | 2023 |
| Max Load | Sources conflict: Emporia's store lists 10A max continuous, 15A peak for up to one hour a day, and separately '1800W @ 120V'. 10A continuous is 1,200W | 15A / 1,800W at 120V |
| Motor / Inductive Rating | Not published. Emporia explicitly advises against refrigerators, freezers, medical equipment, pet heat lamps and pumps, and networking gear | Not published by TP-Link for the KP125M |
| Energy Monitoring | Yes, measured — this is the product's entire purpose | Yes, measured — but only visible in the Kasa app; the Matter integration does not expose it |
| Radio & Protocol | Wi-Fi 2.4GHz to the Emporia cloud. No Matter, no HomeKit, no Zigbee | Matter over Wi-Fi (2.4GHz), Bluetooth for commissioning |
| Hub Required | No | No for the Kasa app; a Matter controller (HomePod, Apple TV, Echo, Nest Hub, SmartThings) is required to use it in Apple/Google/SmartThings |
| Works Without Internet | No documented local API; the app and schedules depend on Emporia's cloud | Yes — Matter commands are local, and Kasa keeps LAN control |
| Switched Outlets | 1 | 1 |
| Pack Size | 1 | 4 |
| Price per Switched Outlet ($) | 11.99 | 9.48✓ |
| Dimensions | Not published by Emporia | Not published by TP-Link on the US KP125M product page |

Pros & Cons
Emporia Energy Monitoring Smart Plug (1-Pack)
Pros
- +The metering is the product, and it slots straight into Emporia's whole-home energy dashboard
- +$11.99 single or $34.99 for four direct from Emporia — the cheapest per-plug metering in the category
- +Emporia is unusually honest about its limits, publishing a continuous rating and a do-not-use list
Cons
- −10A continuous, not 15A — the 15A figure is a peak good for one hour a day, so the real ceiling is about 1,200W
- −Emporia's own store tells you not to plug in a fridge, freezer, pump, heat lamp or router
- −Roughly 80,000 North America Smart Plugs sold July 2022 to May 2023 were recalled by CPSC in September 2023 for inadequate grounding (electric shock hazard); check what you receive
- −Alexa and Google only — no HomeKit, no Matter, no local control, no Home Assistant path
- −Emporia publishes no dimensions, so you cannot tell in advance whether it blocks the second socket
Kasa Matter Smart Plug KP125M (KP125MP4 4-Pack)
Pros
- +Matter multi-admin means the same plug can live in Apple Home and Alexa simultaneously — the Kasa EP25 cannot
- +Matter on/off is handled locally, so it survives an internet outage
- +Street price has fallen to roughly half the $69.99 launch MSRP for the 4-pack
- +2-year warranty and UL certification
Cons
- −The headline energy monitoring is invisible over Matter — you must install the Kasa app alongside your chosen platform to see a single watt
- −TP-Link does not publish a motor/HP rating for this model, so inductive loads are a guess
- −Needs a Matter controller you may not own; the plug alone does nothing in Apple Home without a HomePod or Apple TV
- −Amazon 4-pack pricing swings between roughly $37 and $43, so per-unit comparisons against 2-packs are unstable
