This is in regards to wireless light switches i posted to two other forums. Surely someone here has some experience with the switches that is willing to share. So here is the meat. I have no experience with these switches but I am considering one for the purpose of adding a switch where running wire and adding a 4 way switch just is not the best option. I currently have a conventional 3 way circuit. If I go with a wireless switch, must I replace both wall switches with a receiver or will a conventional 3 way switch also work within this wireless circuit so that I only have to replace one conventional switch with a wireless receiver and simply add the wireless switch in a convenient location within radar distance from the receiver?
