Convert a Hunter Fan (with light) from a wireless remote control to two wall switches

In the beginning wireless ceiling fan controls were simple things consisting of little more than a box of relays (or triacs, or whatever other kind of electrically controlled switch). They were grafted onto an ordinary non-remote-controlled unit either at the factory or as an aftermarket kit. It was easy to add or remove the remote control option.

Now it's more common that the fan is originally designed and built with the wireless unit. It's also more difficult to separate the two because the circuitry that makes the motor work has been migrated into the wireless control unit.

Supposing that the motor itself is still a plain AC motor like they always were it may be possible to achieve your goal. You'll have to figure out which of the motor leads are the correct leads to energize, and it's possible you'll need to add a capacitor to help the motor get started or for speed control. If you measure resistance between pairs of wires on the motor you can figure out which ones have an electrical path between them. You can try blindly energizing them and see what happens..

From here we get into motor control and control design, or into circuit analysis to figure out just enough of what's in that wireless controller for you to either replicate or modify/reuse. That's probably more into the electrical engineering stack than this DIY stack.
