# SFR Box

> SFR Box is a built-in integration for Home Assistant. It has 386 installs sharing analytics and works locally.

SFR Box is a built-in integration that connects Home Assistant to an SFR router over the local network. It adds binary sensors for DSL, FTTH, WAN and VoIP status, including call history and phone hook state. Sensors cover DSL line details such as attenuation, noise, data rate, line mode, training, connection count and CRC errors, along with the network infrastructure type. Buttons are also provided for the box. Setup happens in the UI with the box's host address, username and password, and connection settings can be changed later without removing it. New devices appear automatically, devices that disappear are removed, and a diagnostics file can be downloaded for bug reports.
