- Yes. MatterCatalog matches it to CSA Matter certificate CSA24137MAT42986-24, certified Mar 7, 2024.
- Does the Legrand Smart Plug-In Switch with Wi-Fi (4-Pack) work with Apple Home or HomeKit?
- Likely. It is Matter certified (certificate CSA24137MAT42986-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Apple Home on a page we hold. Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. Apple’s Matter page lists outlets among the accessory types the Home app supports.

- Likely. It is Matter certified (certificate CSA24137MAT42986-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. Google’s supported-device-types page lists the On/Off Plug-in Unit type.
- Does the Legrand Smart Plug-In Switch with Wi-Fi (4-Pack) work with Alexa?
- Likely. It is Matter certified (certificate CSA24137MAT42986-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold. Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does.
- Does the Legrand Smart Plug-In Switch with Wi-Fi (4-Pack) work with Samsung SmartThings?
- Likely. It is Matter certified (certificate CSA24137MAT42986-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named SmartThings on a page we hold. SmartThings adds Matter devices through the SmartThings app and a Matter controller.

- Does the Legrand Smart Plug-In Switch with Wi-Fi (4-Pack) use Thread or Wi-Fi?

- Does the Legrand Smart Plug-In Switch with Wi-Fi (4-Pack) need a hub or a Thread border router?

- When was the Legrand Smart Plug-In Switch with Wi-Fi (4-Pack) Matter certified?
