It can be done with line carriers like Leviton Home controls. You would need
to replace the existing switch with a receiver switch, then install a
transmitter switch anywhere you have or can install a 120 volt power supply

Hello,

I have an existing switch controlling a light circuit. I would like to
add a 2nd switch on the other side of the room. It is possible to do
this without changing the circuit to 3-way wiring and switches?

Thanks,
KJ
