#4 in our rankings · Best for Apple Home
Kasa Smart Smart Plug Mini EP25 (4-Pack)
Best for: Apple households who want Siri control and energy monitoring without buying into Matter or Thread.
Our recommendation
Buy the Kasa KP125M if you want Matter support that works across Alexa, Google, Apple Home, and SmartThings, and you are happy with a two-pack. Buy the Kasa EP25 if the household is Apple-first and you want native HomeKit support in a four-pack. Both offer energy monitoring and the same 15A rating, so the choice is Matter flexibility against HomeKit depth and pack size.
Matter against HomeKit
The KP125M is Matter certified, so one plug can join Alexa, Google Home, Apple Home, and SmartThings, and it keeps working if the household switches assistants. The EP25 has native HomeKit support, so it joins the Home app directly and answers to Siri without Matter, but it cannot join a Matter-only setup. Apple-first households may prefer the EP25 depth, while mixed households should take the KP125M flexibility.
Pack size and cost per plug
The KP125M comes as a two-pack and the EP25 as a four-pack, so the EP25 covers a whole room in one purchase while the KP125M suits a smaller start. The cost per plug is close, so the deciding factor is how many plugs the household actually needs, not the sticker cost.
What they share
Both plugs are rated at 15A with 1800W, both offer energy monitoring in the Kasa app, both use 2.4GHz Wi-Fi, and both have the same slim body that leaves the second socket free. A lamp switched by one behaves exactly like a lamp switched by the other, so the difference is the platform, not the switching.

Choose Kasa Smart Smart Plug Mini EP25 (4-Pack) if…
- Your household is Apple-first and you want native HomeKit
- You want four plugs in one purchase
- You prefer Siri control without setting up Matter

Strengths and limitations
Kasa Smart Smart Plug Mini KP125M (2-Pack)
Strengths
- Matter certification lets one plug join Alexa, Google Home, Apple Home, and SmartThings, so it keeps working if the household switches assistants later.
- Energy monitoring tracks what a connected appliance uses over time in the Kasa app, which suits heaters, dehumidifiers, and gaming setups.
- The slim body is the smallest Kasa plug yet, so two plugs can share one duplex outlet without blocking each other.
Limitations
- Energy data shows in the Kasa app, not in Apple Home, so Apple users still open a second app to see usage.
- It works on 2.4GHz Wi-Fi only, and Matter setup needs a compatible hub or controller for some platforms.
- It costs more per plug than the HS103P2, so buyers who only need basic switching pay for features they will not use.
Kasa Smart Smart Plug Mini EP25 (4-Pack)
Strengths
- Apple HomeKit support means Siri can switch connected devices, and the plug appears in the Home app alongside other Apple gear.
- Energy monitoring reports real-time use and history in the Kasa app, which helps track heaters and other heavy loads.
- The four-pack covers a living room or a set of lamps in one purchase, and each plug still leaves the second socket free.
Limitations
- Remote control through Apple Home needs an Apple hub at home, such as a HomePod or Apple TV.
- It works on 2.4GHz Wi-Fi only, so the 2.4GHz band must be switched on if the router hides it.
- It is not Matter certified, so it cannot join a Matter-only setup the way the KP125M can.

Made your call?
Questions, answered
Can I use both plugs in the same home?
Yes. Both use the Kasa app, so they sit side by side in one account, and both can join Alexa routines. The EP25 also appears in the Home app, while the KP125M joins Apple Home through Matter.
Which shows energy data better?
Both show energy data in the Kasa app only, not in Apple Home. There is no difference between them on energy reporting.
Do they need different apps?
No. Both plugs use the Kasa app for setup, schedules, and energy data, so one app covers the whole Kasa household.
