I couldn't find any documentation if the Home Control App supports URL schemes... Does it? If not, is this something that could be added. I think it would be very useful.
URL schemes work like this. You enter a URL (in safari, or with an app like Launch Center or IFTTT), and it opens an app and does things within that app. So, you could have an URL like this: HomeControl://activateScene?name=Home or HomeControl://activateDimmer?name=outdoor&value=75. Basically its a way to activate a specific scene or light from outside the app.
Use cases I'm imagining would involve using the IFTTT app on my phone to automatically activate a scene when I arrive home or when I leave. By using URL schemes the IFTTT app is essentially able to tell the Home Control app to activate a particular scene.
