How do I wire a hard-wired wall switch and a remote for my ceiling fan/light?
Simplest answer is probably to get a second remote and velcro it to the wall, unless the controller is designed to also support a physical switch via a switch loop or the "toggle off and on again rapidly" signalling mechanism. Docs for the controller should answer that question; if they don't tell you how to also use a wall switch you probably can't -- or at least can't use it as anything but a master power switch.
