Best smart plugs for Alexa in 2026 (and how to set them up)
Amazon’s own plug is the easiest to set up. A Matter plug like the Kasa KP125M is the smarter long-term buy, and it still works with Alexa.

The best smart plug for Alexa in 2026 is a Matter plug, not necessarily Amazon’s own. Recent Echo speakers and displays act as Matter controllers, so plugs like the Kasa KP125M pair straight into the Alexa app. You get energy monitoring and the freedom to add Apple Home or Google Home later. The Amazon Smart Plug is still the simplest setup in an Alexa-only home.
| Plug | How it connects to Alexa | Energy monitoring | Other ecosystems | Price |
|---|---|---|---|---|
| Kasa KP125M | Matter (or Kasa skill) | Yes | Apple, Google, SmartThings | ~$15 |
| Amazon Smart Plug | Native Alexa | No | None | $24.99 |
| Tapo P125M | Matter (or Tapo skill) | No | Apple, Google, SmartThings | ~$10–$13 |
| Eve Energy | Matter over Thread | Yes | Apple, Google, SmartThings | ~$40 |
Best Alexa smart plug: Kasa KP125M
Pair the KP125M as a Matter device in the Alexa app and it runs locally from your Echo. It also reports energy use in the Kasa app, which helps when you’re building an Alexa routine to switch off an idle dehumidifier.
Easiest setup: Amazon Smart Plug
If your Amazon account is linked, the Amazon Smart Plug can set itself up with Frustration-Free Setup and no extra app. It’s Alexa-only and has no energy data, which is fine for a lamp and a poor choice for a growing smart home.
Useful Alexa smart plug routines
- “Alexa, good morning” turns on the coffee maker plug and the hallway lamp.
- Sunset turns on porch string lights. Midnight turns them off.
- An Alexa Hunch or away routine switches off the TV cabinet strip when everyone leaves.
- A motion sensor plus a plug lamp makes a hallway night light.
Questions we get
How do I pair a smart plug with Alexa?
For a Matter plug: plug it in, open the Alexa app, tap Devices > + > Add Device > Other > Matter, and scan the QR code on the plug or box. For a non-Matter plug, set it up in the maker’s app first, then enable that brand’s Alexa skill.
Does Alexa need a smart plug?
No. Alexa works on its own, but a smart plug lets Alexa control ordinary devices like lamps, fans, and coffee makers by voice, routine, or schedule.
What is an Alexa smart plug?
Any smart plug that Alexa can control. That means Amazon’s own Smart Plug, any Matter-certified plug, or a plug whose maker offers an Alexa skill.
What are the disadvantages of smart plugs?
They only switch power on and off, so they can’t dim lights or change device settings. They can’t safely run high-draw heaters, and Wi-Fi models add load to your network. Matter and Thread plugs reduce the cloud-dependence problem.
Which smart plug is best for Alexa connectivity?
A Matter plug paired directly to an Echo. It connects locally, so routines run faster and keep working if the plug maker’s cloud goes down.
