Battery-powered retrofit remote control device

A remote control device configured to be mounted over an installed light switch, the light switch having a toggle actuator that extends through a faceplate opening of a faceplate of the installed light switch, the toggle actuator configured to control whether power is delivered to an electrical load, the remote control device comprising:

• a control interface comprising an intensity adjustment actuator;
• a base portion configured to support the control interface, such that the intensity adjustment actuator is moveable relative to the base portion, the base portion defining a rear surface comprising a toggle actuator opening that is configured to receive a portion of the toggle actuator when the remote control device is mounted over the installed light switch, the base portion comprising a plurality of fingers on opposed sides of the toggle actuator opening, the plurality of fingers configured to attach the base portion to the toggle actuator;
• a wireless communication circuit;
• and
• a control circuit responsive to the control interface and communicatively coupled to the wireless communication circuit, the control circuit configured to, in response to an actuation of the intensity adjustment actuator of the control interface, transmit, via the wireless communication circuit, a control signal that causes an adjustment of an amount of power delivered to the electrical load.
