Yes. If you have two switches that control one light and want to control the light with a Decora Digital switch or dimmer, you will need to replace one switch with a Decora Digital Bluetooth switch or dimmer. The other would be replaced with a Matching or Coordinating Companion:
- DD00R-DLZ - Decora Matching Dimmer/Fan Companion – use for 3 or 4 way dimming applications. Neutral required
- DD0SR-DLZ - Decora Matching Switch Companion (with Status LED) – use for 3 or 4 way switch applications. Neutral required
- DD0SR-1Z - Decora Coordinating Switch Companion (no Status LED) – use for 3 or 4 way for switch applications. Neutral required
