Leviton · model D26HD · For the US and Canada
- Matter Yes, over Wi-Fi
- Apple Home Yes
- Google Home Yes
- Amazon Alexa Yes
- SmartThings Yes
- Home Assistant Via Matter
Leviton's D26HD is a Wi-Fi dimmer in the Decora style that replaces a US wall switch and needs a neutral wire. Leviton lists Apple Home, Alexa, Google Home and SmartThings with no hub. A firmware update in the My Leviton app adds Matter, which is how Home Assistant reaches it. The update removes the HomeKit pairing, so you re-add it to Apple Home with the Matter code and an Apple home hub. It dims 300 W of LED or 600 W of incandescent.

| Google Home | Yes | Through the My Leviton cloud link; Matter is also an option after the firmware update.[1],[3] |
| Amazon Alexa | Yes | Through My Leviton; Matter is also an option after the firmware update.[1],[3] |
| SmartThings | Yes | Leviton lists SmartThings and says the Matter update leaves the existing integration alone.[1],[3] |

“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.
