About resetting the device
Notice
Risk of losing your data and configuration
- This process clears the data disk on your device. Unless you create a backup, you will lose all data and configuration settings.
- A device reset wipes the data partition. 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.
Resetting the device
The steps to clear the data disk differ, depending on whether you use a Raspberry Pi Compute Module 4 or 5 with your Home Assistant Yellow.
Prerequisites
- During this procedure, Home Assistant needs an Internet connection.
- You need Administrator rights to do this procedure
