KC868-32BS state from wall switch

[udayansarma]

How do I retain the state changes trigger from 12vdc wall switch that triggers the existing momentary relays? Please take a look at the existing relays and the wiring in the attached picture, all the yellow wires are triggers to those Finder relays. When I use the trigger from the 32BS controller both the apps and wall switches are in sync because the existing relays and triggers keep the wall switches in sync. But if I trigger via the wall switch, the app and the controller are not able to retain any state. Where the existing trigger wires (yellow for +ve and black for ground) should go to 32BS controller so the states between the controller, app and the wall switches are all in sync? 

Thanks much
