Leviton Decora Smart: Match the Generation, Wiring and App
Decora Smart covers several product families. Select by the exact model and documented wiring requirements, then confirm the app and companion controls that belong to that generation.

Use the full model number
Write the complete switch or dimmer code into the quote rather than the brand family alone. Similar faceplates can conceal different connectivity and installation requirements that matter during a retrofit.
Confirm neutral and network
D215S documentation specifies a neutral connection, and its Wi-Fi setup has its own requirements. Have the existing box and final network location assessed before ordering multiple rooms of equipment.
Include companions and handover
For multi-location circuits, confirm the approved companion arrangement for the chosen generation. Ask the installer to show manual operation and the appropriate app controls, including how the household owns the account.
