Focus development mainly on mobile app
I manage most of my daily activities from my mobile now days. The server should just basically control your devices and USB stick, and connects to the cloud or directly to your mobile app. No need there for a complicated GUI, only manage server options. Everything else should be handled from the mobile app: be able to control every aspect of the server app, add/remove devices, create and control scenes, etc.
The logic would be server side (i.e. local) but could be controlled over the cloud.
I can ABSOLUTELY follow this logic. I was just going to request the ability to quickly enable/disable a scene on the mobile side. But this suggestion is even better :)
