b. turn the light on or off at the socket switch itself independent of the remote switch status edge switch,
c. able to use LED bulb
d. does not require a ground or neutral (regular old wire to the lamp.
This should not be hard - there is always power to the wire. A specalized relay can be connected directly to even an old lamp socket on the same lamp if need be - or at the plug :slight_smile
