Retrofit remote control devices

A remote control device that is configured for use in a load control system having a load control device, the load control device configured to control an amount of power delivered to an electrical load that is electrically connected to the load control device, the remote control device comprising:

• an adapter that is configured to be attached to a first yoke of a mechanical switch that controls whether power is delivered to the electrical load, the adapter configured to be attached to a second yoke of a second electrical device that is mounted adjacent to the mechanical switch in a multi-gang wallbox, the adapter defining first and second openings;
• a control unit that is configured to be attached to the adapter, the control unit including a user interface and a wireless communication circuit, the control unit configured to translate a user input from the user interface into a control signal that controls the load control device, and to cause the wireless communication circuit to transmit the control signal;
• and
• a faceplate that is configured to be attached to the adapter, the faceplate having a faceplate opening that is configured to receive at least a portion of the user interface;
• a first set of screws that attach the second yoke of the second electrical device to the multi-gang wallbox;
• and
• a second set of screws that attach the adapter to the second yoke of the second electrical device,
• wherein when the mechanical switch is mounted in the multi-gang wallbox adjacent to a second electrical device, the first opening is configured to surround a bezel of the mechanical switch and the second opening is configured to surround a portion of the second electrical device, and wherein the second yoke of the second electrical device is configured to be drawn outward from the multi-gang wallbox when the first set of screws are loosened and the second set of screws are tightened.
