If you are weighing a Kasa vs Wemo smart plug, the answer changed in 2026. Belkin announced that Wemo support would end on January 31, 2026, and that shifted this from a close feature comparison to a question of which plug will actually keep working.
Both brands built their names on simple plugs that turn lamps, fans, and small appliances on and off from your phone. Here is how they compare now, and who should buy which.
How We Picked
We did not lab-test these plugs. Instead, we compared official specs from TP-Link and Belkin, Belkin’s published end-of-support notice, coverage from tech outlets, and patterns in verified customer reviews. Because Wemo’s situation is unusual, we weighted long-term support more heavily than we normally would.
Kasa vs Wemo Smart Plug, At a Glance
| Product | Price | Best For | Our Rating |
|---|---|---|---|
| Kasa Smart Plug Mini EP25 | Check price | Most households, Alexa and Google Home | 4.7 / 5 |
| Wemo Smart Plug with Thread (WSP100) | Check price | Apple Home only households | 4.1 / 5 |
1. Kasa Smart Plug Mini EP25, Best Overall
The Kasa EP25 is a compact Wi-Fi plug from TP-Link’s Kasa line. It connects straight to your 2.4GHz network, so there is no hub to buy or maintain.
It works with Alexa and Google Home, and it supports Apple HomeKit as well. That flexibility is the main reason it wins here: you are not locked into one ecosystem if you switch phones or speakers later.
The EP25 also includes energy monitoring in the Kasa app. You can see how much power a space heater, a window AC, or a gaming setup draws, which is useful if you are trying to trim your electric bill.
Customer feedback on Kasa plugs tends to praise quick setup and reliable schedules. The common complaint is the 2.4GHz-only Wi-Fi requirement, which can make initial pairing fiddly on some mesh systems.

2. Wemo Smart Plug with Thread (WSP100), Best for Apple Home Households
The Wemo WSP100 is the notable survivor in Wemo’s lineup. It uses Thread, Bluetooth, and NFC rather than relying on Wemo’s cloud.
According to coverage of Belkin’s announcement, Thread-based Wemo products, including the WSP100, are expected to keep working through Apple Home after the shutdown. That makes it a reasonable pick if every phone and hub in your home is Apple.
The tradeoffs are real, though. It is built for Apple Home, so you will not get the broad Alexa and Google Home support you get with Kasa. You also need a Thread border router, such as an Apple TV 4K or HomePod mini, for remote access.
It has fewer reviews than the Kasa plugs, and Belkin’s decision to wind down the Wemo app is a reasonable reason to be cautious about the brand’s future.
Wemo Smart Plug with Thread (WSP100)
- Connects over Thread, Bluetooth, and NFC
- Built for Apple Home and Siri control
- Slim design that lets you use both outlets
- Still supported after Wemo's cloud shutdown

Pros
- Kasa plugs still work with the Kasa app, Alexa, and Google Home, with remote control away from home
- The Kasa EP25 adds energy monitoring so you can see what a device costs to run
- Wemo's Thread plug (WSP100) keeps working locally through Apple Home after the cloud shutdown
- Neither plug needs a separate hub when paired with Wi-Fi (Kasa) or an Apple Home hub (Wemo Thread)
Cons
- Most Wemo plugs lost the Wemo app, remote access, and Alexa and Google Home integration after January 31, 2026
- Kasa plugs connect to 2.4GHz Wi-Fi only, which can trip up some mesh router setups
- The Wemo Thread plug is built for Apple Home and has no Alexa or Google Home path through Wemo
What Happened to Wemo’s Cloud?
Belkin said that after January 31, 2026, the Wemo app and cloud features would stop working for most products. That covers remote access and integrations with Alexa and Google Assistant.
Devices already set up in Apple HomeKit are expected to keep working locally, and Thread-based Wemo products continue through Apple Home. But new setup or reconfiguration through the Wemo app is no longer possible for older Wi-Fi models.
If you already own older Wemo plugs, check Belkin’s support page for your model. If you rely on voice control or remote access, replacing them with Kasa plugs is the simplest fix.
How to Choose Between Kasa and Wemo
Start with your voice assistant. If you use Alexa or Google Home, Kasa is the clear choice, because Wemo’s integrations with those assistants ended for most products.
If you are all-in on Apple, both can work. Kasa supports HomeKit on models like the EP25, while the Wemo Thread plug is built around Apple Home from the start.
Next, think about energy monitoring. If you want to see what an appliance costs to run, the Kasa EP25 includes it. The Wemo Thread plug is a simple on/off plug.
Finally, consider long-term support. A plug is only useful if the app and cloud behind it stay around. Kasa’s active ecosystem is a safer bet than a brand that just wound down a major platform.
Our Verdict
Kasa wins this comparison for most buyers. The EP25 works with Alexa, Google Home, and HomeKit, adds energy monitoring, and comes from a company that is still actively supporting its app.
The Wemo Smart Plug with Thread is a narrow pick for Apple-only homes that want a Thread device. Everyone else should look at Kasa.

If you are building out the rest of your smart home, pair these with a smart speaker for Alexa or a smart lock that works with your smart home.
