/*:
 This is a concept re-implementation of the @Binding and @State property wrappers from SwiftUI

 The only purpose of this code is to implement those wrappers myself
   just to understand how they work internally and why they are needed,

 ⚠️ This is not supposed to be a reference implementation nor cover all
      subtleties of the real Binding and State types.
    The only purpose of this playground is to show how re-implementing
      them myself has helped me understand the whole thing better

Elgato Eve HomeKit Services & Characteristics

A work in progress collection of proprietary and as of yet undocumented HomeKit characteristics and their UUIDs used by Elgato Eve.

Based on the work by gomfunkel and 0ff. Characteristics and data dump for Door, Motion and Thermo thanks to @NebzHB.

More infos not yet incorporated in the comment section.

This list is not including all Eve accessories available and some services and characteristics still make no sense to me. If you have anything to contribute, please leave a comment. There is no guarantee that the information listed below is correct.
