Connect it to the ring bridge (sold separately) to unlock smart controls and custom combinations in the ring app. The ring bridge lets you group together ring smart lights and connect them to ring doorbells and cameras. If one ring bridge-enabled device detects motion, it can turn on lights, activate your cameras and more. The ring bridge also links your ring smart lights to select alexa-enabled devices, so you can turn on lights and adjust settings at the sound of your voice.
