This is a dual HOA switch for motion sensing outdoor lights. I used common (inexpensive) motion sensing lights with some modifications and designed a PCB to fit in a dual gangbox, so the digital HOA, complete with nice LED indicators, can be mounted easily on the house with a customized dual gangbox faceplate. Each light can be controlled by a combination of the two motion sensors, and each light has its own ON time that can be set from the switches on the dual HOA interface.
