Model: KS230 KIT  
Hardware Version: V2
Firmware Version:

thank you in advance for the help 

 

this is a new construction 

 

i have 2 boxes 

 

box A has only 14-3 wires in it red-black-green-white

 

Box B has the 14-3 wires + 14-2 going to lights + 14-2 line (power) 

 

how can i wire the Kasa 3 way dimmer switch ? and is it possible to do in this setup

I'm afraid your current wiring won't be able to install the Kasa KS230KIT switch. To install the KS230 3-way switch, the load wire for controlling the lights and the load wire to the power source should be in different boxes.

 

The installation guide for the Kasa KS230KIT can be found below.
