[QUOTE="SPECIAL LOCATION, post: 553226, member: 250"] Not 100% what you describe is actually the norm? I see many different arrangements... However re your dimmer question.... without giving it a try to see what happens I don't know?.. However you do need to remembering that it is the light turning off that starts the fan timer... So the question is how low can you dim the lights for it to still work without the fan thinking the lights are off?? I think I have seen dimmers triggering fans in the past... But I am also sure I recall various problems with LED's still glowing when turned off due to sharing supplies with a timer fan? Dimmers and LED's can be a pain in the bum as it is.. Adding a timer fan as well onto the same equation could be just another can of worms.. If you can access the wiring above the ceiling but not down the walls.. could you fit a ceiling mounted motion sensor to trigger the fan, and leave your dimmer just doing the lights?? Or.. leave your switch just for the fan.. and get some smart lights you can dim from a phone App? [/QUOTE]
