The Leviton Decora Smart Wi-Fi 2nd Gen Switch (D215S) is a rocker switch that replaces your existing wall switch and needs a neutral wire and a 2.4 GHz Wi-Fi network, with no hub. Leviton rates it for 600W LED/CFL, 1500W incandescent or halogen and 3/4 HP motor loads. It works single pole or 3-way with Leviton's wired or wire-free companions, and Leviton says Matter is turned on with a firmware update in the My Leviton app.

Quick answers
- Is the Leviton Decora Smart Wi-Fi 2nd Gen Switch Matter certified?
- Yes. MatterCatalog matches it to CSA Matter certificate CSA23178MAT40691-24, certified Mar 2, 2023.
- Does the Leviton Decora Smart Wi-Fi 2nd Gen Switch work with Apple Home or HomeKit?
- Yes. The maker’s own site names Apple Home, and it is Matter certified (certificate CSA23178MAT40691-24). 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 lights among the accessory types the Home app supports.
- Does the Leviton Decora Smart Wi-Fi 2nd Gen Switch work with Google Home?
- Likely. It is Matter certified (certificate CSA23178MAT40691-24), 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 Light type.
- Does the Leviton Decora Smart Wi-Fi 2nd Gen Switch work with Alexa?
- Yes. The maker’s own site names Alexa, and it is Matter certified (certificate CSA23178MAT40691-24). 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 Leviton Decora Smart Wi-Fi 2nd Gen Switch work with Samsung SmartThings?
- Yes. The maker’s own site names SmartThings, and it is Matter certified (certificate CSA23178MAT40691-24). SmartThings adds Matter devices through the SmartThings app and a Matter controller.
- Does the Leviton Decora Smart Wi-Fi 2nd Gen Switch work with Home Assistant?
- Likely. It is Matter certified (certificate CSA23178MAT40691-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Home Assistant on a page we hold. Home Assistant says: “Adding a new Matter device only works in the Home Assistant Companion app.”
- Does the Leviton Decora Smart Wi-Fi 2nd Gen Switch use Thread or Wi-Fi?
- Wi-Fi. Its catalog record lists Wi-Fi, so it joins your Wi-Fi network and does not need a Thread border router. You still need your platform’s Matter controller.
- Does the Leviton Decora Smart Wi-Fi 2nd Gen Switch need a hub or a Thread border router?
- No hub of its own and no Thread border router: it joins your Wi-Fi network. You still need your platform’s Matter controller (a smart speaker, display, streaming box or hub), though Apple says an iPhone using iOS 18 or later can add Matter accessories without a home hub.
- When was the Leviton Decora Smart Wi-Fi 2nd Gen Switch Matter certified?
- The CSA certified it on Mar 2, 2023 (certificate CSA23178MAT40691-24). That is its certification date, not a retail release date, which MatterCatalog does not state.
- Where can I buy the Leviton Decora Smart Wi-Fi 2nd Gen Switch?
