# 飞牛fnOS

> 飞牛fnOS is a Marketplace integration for Home Assistant. It has 125 installs sharing analytics, works locally and was last updated October 21, 2026.

飞牛fnOS is a Marketplace integration that connects Home Assistant to fnOS over the local network. It adds sensors for memory and disk usage, CPU temperature, load average, CPU utilization and device status, plus binary sensors for security status and disk wear warnings. Sign-in uses an fnOS administrator account, and a six-digit two-factor code is requested when the account has one enabled. The integration can ask fnOS to trust the Home Assistant device so later code prompts are fewer, and it offers a reauthentication step when the saved login expires. Polling intervals are adjustable separately for system data and for disk data, and shorter disk intervals may keep hard drives from entering standby. More than one fnOS system can be added under the same integration.
