The Halo Home in-wall accessory dimmer controls your Halo Home lighting devices from a central location. The accessory dimmer is designed to connect to the Halo Home Bluetooth Mesh network with no hub or internet connection required. The accessory dimmer can occupy any position in a multi-gang junction box, while the other positions of the junction box can be occupied by switches or other dimmers. The accessory dimmer can operate Halo Home lighting fixtures with single, three-way or multi-switch controls. For standard lights, the accessory dimmer can be used for multi-switch control when paired with Halo Home in-wall smart dimmer.
