How to create a partnership of 2 devices

Hi, i am new with smarthings but i have working with vera most two year with many devices different.

within vera functions is the ability to associate a device with other groups through achieving a 2-way communication .

Example: 2 dimmable switches from one side of the room and shuts off from the other and vice versa.

how to do this with Smarthings ?

Check out Rule Machine or there is another smartapp floating around “Trend Setter”. Best way to setup your logic…
