Smart switches connect through wireless protocols such as Z-Wave, Zigbee, or PowerG, or through wired connections to a compatible lighting system, hub, or security panel. Once paired with the appropriate platform, they can support control from an app, voice assistant, wall control, or automated scenes, schedules, and security events, depending on system compatibility.

Before installing smart switches, verify the circuit voltage, load type, amperage, and whether the device requires a neutral wire, since options in this category support different requirements such as 120 V, 120/277 V, and loads that include lighting, fans, motors, or outlets. Review the wiring method, terminal or wire-gauge requirements, and whether the device is a load-bearing switch, companion control, or plug-in unit, then confirm that the circuit is de-energized before wiring.

Smart switches can control a light from one location in a single-pole setup, or from multiple locations when paired with compatible companion, remote, or wireless controls. For three-way and multi-location applications, installers should match the switch and accessory type, confirm whether a neutral wire is required, and follow the system’s wiring and hub requirements.

Smart switches in this category can control LED, incandescent, halogen, compact fluorescent, fluorescent, electronic low-voltage, and magnetic low-voltage lighting, along with fans, motors, wall outlets, and small appliances. Load capacity and neutral-wire requirements vary by switch, so confirm the product specifications for the intended application.
