I want to replace my current setup:  

• Insteon Switches (I would link, but the forum does not allow it)

• Four lighting zones
• Switch 1 at top of stairs turns on, off, and dims all zones
• Switches 2-4 turn on, off, and dims each individual zone

Here is my current wiring setup.   

I think that this is achievable using TP-Link switches and a Smart Action based on this article www.tp-link.com/us/support/faq/2567.

Would four HS220 switches for the four zones and a HS200 for S1 at the top of the stairs work? 

Would I wire it the same way as the Insteon Switches?
