Hi,
always great if someone wants to contribute in hyperion.
SInce there is no official ios app for hyperion and the one in the app store is closed source i think you can't get information there.
The creator of the android app is in this forum as well. Perhabs you can drop him a PM.
If you are thinking about creating a application for hyperion.ng I am happy to help you. I can assist with questions about hyperion and the commands you have to send.
Just drop me am PM and we can look together into this. I wanted to learn something about react long time now, haha
I PMed you.
