If you have EnderIO and project red - insulated redstone cables interact with most RF equipment and wireless sender/receiver can do the rest - not sure but you may need to connect the insulated redstone to a Stone (or other) block and direct the receiver to the block.
Thanks...actually I figured it out another way....redstone conduits that ride the EIO Conduit cable, where I want the shut-off point to be, then extend that RS Conduit to my top floor with a switch to control it being on/off.
