LedFX appears to only support LAN connections (all the examples are calling the API with a local IP address, at least). I won’t be able to build an app for that, since I need some kind of way to remotely debug the connection via the cloud. When I reverse engineer devices (or rather the Android apps from the manufacturers, not really the devices themselves), I can figure out most parts of the protocol without having the device (I can create an account, log in and see how the app requests its device list, and also replicate a real API response by modifying the response that the mobile app receives). This is way harder for LAN connections, as that often also needs discovery which you can’t easily clone or modify the responses from.
But maybe another developer can help you with this. There is a dedicated app requests topic also:
