Recovery mode
The Recovery mode integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] is an internal integration used by the Home Assistant Core.
You don’t have to configure it since it is automatically always available when Home Assistant needs it.
If, during startup, Home Assistant has problems reading your configuration, it will still continue to start using parts of the configuration from the last time Home Assistant did start.
When this happens, Home Assistant will start in Recovery mode using this integration. In this mode, no user configured integrations are loaded, but it does give you access to the Home Assistant frontend, settings and add-ons.
This gives you the possibility to correct the issue and restart Home Assistant to re-try.
