I am looking for a solution for my outdoors (back deck) that will allow me to use dimmable LEDs along with a dawn-to-dusk feature. My existing exterior light fixtures have photosensors for the dawn-to-dusk feature so they automatically come on and off, but are not dimmable. I want the dawn-to-dusk feature with full brightness the majority of the time for security reasons, but I'd also like to be able to dim them when entertaining on the back deck during the evenings. Can I use Caseta with these existing photosensor fixtures, or do I need to replace them with exterior lights that don't have the photosensor?
