   A pair of switches wired together to control a single light (or set of lights) from two locations, commonly found at the top and bottom of stairs.

   American English: 3-way switch
   British English: 2-way switch

   Setups with three control points are called 4-way and 3-way in the US and UK respectively.

     Anyway, I now have a way to control lights from two switches except instead of a wired XNOR switch, it's two WiFi devices sending messages to each other through an MQTT server.

     This seemed easier.

     2-way sounds logical because one normally goes in two ways on stairs.

     But, I think the reference to 3-way is about the wiring.

     @ryanc A fabric which stretches in one direction is said to have “two-way stretch”. A “two-way mirror” is only a mirror from one direction. Almost every instance of a term with “way” in it is mind-numbingly wrong.
