I think initially it will be hard to support all features through the cloud server, i.e. it will be difficult to get every part of the app to work with cloud. Instead, like the current design of OG — some parts, like changing settings, still require local network; but other parts, such as starting a program, testing a value, checking current station status, will be available through cloud. You are correct that the app can read the firmware version to present the UI differently for different firmware (and this is what we do arleady).
