Perform this procedure if you want to perform a factory reset on your device.
Prerequisites
- Home Assistant Green
- microSD card
- Memory card reader for microSD (your computer might have an integrated card reader, otherwise use an external one)
- Computer with internet access
- You have created a backup and stored it on another system
Notice
Risk of losing your configuration
This process clears the data disk on your Green. Unless you create a backup, you will lose all data and configuration settings.
- A device reset wipes 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 device wipe 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.
- To avoid losing data and configuration settings, create a backup and define a backup location outside of your Home Assistant.
