In a single-pole installation, the compatible in-wall switch or dimmer controls the connected light, while a paired remote can provide an additional control point. In a multi-location installation, companion remotes communicate with the primary switch or dimmer, allowing users to turn lights on or off, and with compatible dimmers, adjust brightness from multiple locations.

Check the device requirements before installation, since many in-wall switch remote controls use 120V power, require a neutral wire, and fit standard wall boxes, while some accessory switches use 3-way wiring for multi-location control. Wireless paddle remotes typically run on a battery and mount to a wall with a bracket, so they can add a control point without pulling new wire or cutting a wall box, but they must be paired with a compatible switch or dimmer.

Wired accessory controls connect to the primary switch or dimmer through three-way circuit wiring, typically install in a standard wall box, and may require a neutral wire. Wireless wall-mounted remotes pair with a compatible smart switch or dimmer and use a mounting bracket, allowing an added control point without pulling new wire or cutting into the wall.

Check that the remote uses the same lighting-control system or wireless protocol as the primary in-wall switch or dimmer, and confirm support for single-pole, three-way, or multi-location operation. Before installation, verify the circuit voltage, neutral-wire requirement, load type, and any pairing limits, such as the number of accessory controls the system supports.
