Wemo Smart Plug with Thread (WSP100): what it works with
Wemo · model WSP100 · sold in US
Built for Apple HomeKit and nothing else, the Wemo WSP100 joins Apple Home directly over Bluetooth or Thread; Belkin says it doesn't work with Google Home or Alexa. Home Assistant can pair it through its official HomeKit Device integration instead. Because it never used the Wemo app or cloud, Belkin says it keeps working through HomeKit after the Wemo cloud shutdown. The US plug is rated 120 V / 15 A / 1800 W and has no power reporting.

Ecosystem compatibility
| Platform | Works? | Details |
|---|---|---|
| Matter | Unconfirmed | Belkin describes it as a HomeKit-only device and never mentions Matter for it. No CSA listing found. Not confirmed either way. |
| Apple Home | Yes | HomeKit (HAP) over Bluetooth and Thread, set up with NFC or the HomeKit code. Thread and remote control need an Apple home hub with Thread (Apple TV 4K 2021 or HomePod mini).[1],[2],[3] |
| Google Home | No | Belkin's FAQ answers "No" for Google Home and says the plug is designed for use only with Apple HomeKit.[2] |
| Amazon Alexa | No | Belkin's FAQ answers "No" for Amazon Alexa and says the plug is designed for use only with Apple HomeKit.[2] |
| SmartThings | Unconfirmed | Belkin says the plug is designed only for Apple HomeKit and lists no Matter support, but no Belkin or Samsung page names SmartThings either way. |
| Home Assistant | Yes | Home Assistant's official HomeKit Device integration pairs HomeKit accessories over Bluetooth and Thread (Thread needs a border router). HA doesn't name the WSP100, and a HomeKit accessory pairs with only one controller at a time.[5] |
“Via Matter” means you add it with that platform's Matter controller instead of a brand skill or app. “Unconfirmed” means we couldn't find an official source either way. How we verify.
Specs that matter for setup
- Radio: Bluetooth LE 5.0 and Thread (802.15.4), per Belkin's spec article.
- Hub: Belkin's sources disagree: the FAQ says a hub is needed only for Thread and away-from-home control, while the spec list says you need an Apple home hub or Thread hub.
- Local control: Runs on HomeKit with no Wemo app or cloud; Belkin says Thread Wemo devices keep working through HomeKit after the Wemo cloud shutdown.
- Energy monitoring: Belkin's FAQ says the WSP100 has no power reporting.
- Max load: 120 V, 15 A, 1800 W. The Thai version (WSP100-TH) has a different rating.
