About factory reset

A factory reset clears the data partition of your device. It removes all user data as well as Home Assistant Core, Supervisor, and any installed add-ons.

The Home Assistant operating system stays on the system.

Once a factory reset is initiated, the data partition is marked as to be cleared on boot. Then, the system reinstalls the latest version of all Home Assistant components.
