if you are lucky and there's an aircond/water heater switch next to it then you can tap the neutral wire.
else you are out of luck. need to pull from the top.

planning to use smart switch?

nah, lazy to change all switches and configure them 1 by 1
just got light sensor for back yard to turn on when dark
timer for front porch to turn on in the evenings
and a remote control switch for master bedroom so no need to walk to the wall switch


my home automation is done!

oh, still looking for a reliable motion sensor to turn on upstairs hall lights.
