# AirTray: reconstructing an Elgin Air cloud client

> AirTray reconstructs an Elgin Air app client as a Windows system-tray controller for compatible air conditioners. It signs in with the owner's account, discovers registered devices, reads their state and sends temperature, mode and power commands through the cloud service. The author reports live validation on one authorized device and account.
