When installing a No-Neutral (DN6HD or DN15S) dimmer or switch in a 3-way or 4-way application most users will install the DAWDC Decora Smart Anywhere Dimmer Companion or DAWSC or Decora Smart Anywhere Switch Companion. These RF Companions can be mounted on an electrical box or any wall surface using screws or mounting tape. The result is a traditional looking wall mount control with no new wires. For more information see this video.
For rooms with multiple My Leviton supported devices or for a more customized application you can use the DW4BC: Wi-Fi 4 Button Controller or the D2SCS: Wi-Fi Scene Controller Switch. For information on the DW4BC see How Do I Configure the Buttons On the DW4BC Or D2SCS Controller.
The Decora Smart No-Neutral Dimmer and Switch are not compatible with the DD00R/DD0SR hardwired remotes.
