This guide explains how to factory reset Home Assistant Green.

Please be sure to backup before factory resetting if you wish to restore your current data on the new installation.

Important notes:

    • After successfully initiating the reset process, Home Assistant OS will be re-installed automatically
    • The LEDs start blinking
    • The Home Assistant Operating System now downloads the latest version of Home Assistant Supervisor and Home Assistant Core
    • Due to these downloads, it can take a while until Home Assistant becomes accessible again

Method 2: Factory Reset via SD Card (Advanced)

This method should only be used as a last resort. Only use this method if…

    • The reset button method above does not work

    • Home Assistant Green will not boot

    • You suspect your Home Assistant Green Internal Storage has become corrupted (you will need a SD Card)

    • The system is stuck in a boot loop

This process is not recommended for beginners unless advised by support – please see this excellent guide for Factory Resetting Home Assistant Green via SD Card.
