I am hoping to control one set of lights via three switches where I would like, at least one of the three, switches to be a smart switch with dimmer capability.  I currently have the lights wired up with two 3-way switches, and one 4-way.  I say I have them wired up, but truthfully someone did this for me.  Can I simply purchase the KS230 KIT to swap out the two 3-way switches to achieve my goal?
