The porch lights and porch fan (Separate fixtures) are wired to a single switch in one room. This single switch is part of a three way switch configuration that is located in another room. From the living room or the bedroom you can turn the light and fan on and off. If there a way to move the light to the switch in the living room and the fan to the switch in the bedroom so that the fixtures can update independently of one another? Basically eliminating the three way capability? Need the switch in bedroom to only operate the fan and other to only operate the light - each switch independent of one another.
It could be easy depending how it is wired.
If it is wired:
Switch ------------light ----------fan-------- switch -----main feed
Then the two travelers should pass through the fan and light.
In this arrangement, you could change the fan to be fed from traveler A and the right switch would control it. Then hot wire traveler B in the right switch, remove traveler A from the switch in the left switch and cap it, and leave the light on the switched hot and the left switch would control the light. Then each switch would control one item.
Investigate your wiring and let us know where the hot feed comes in.
Basically, you have several wires and can accomplish this but it will take some ingenuity and investigation.
