# wibox-daemon: reconstructing Fermax Wi-Box control and media transport

> wibox-daemon reconstructs Fermax Wi-Box IDS7938 communication in a Go service for door control and media access. Its protocol reference describes cloud userauth XML, UST MQTT discovery, an RB-UDP tunnel and local QUII. The daemon exposes HTTP controls and outputs H.264 video with optional G.711A audio.
