I have living room sealing ambilights with two segments. I want to control them independently. And it would be nice to have relay switch off when both segments are off and relay on when one, or both segments are on.  
I managed to figure out how to control segment with switch. And I can do it with two key wall mount regular switch. But relay stays on, when both segments are off. And if I switch off leds in app, then segmens are not reacting to switch.

Any ideas how to make it work with API?

you can’t with stock FW  
you can do it using Multi relay usermod, mark relays as external and then modify presets to include relay commands
