Changing a device address or an account setting does not have to mean deleting its Home Assistant integration and starting again. A broad set of integrations gains reconfiguration, covering connections such as ONVIF cameras, Harmony hubs, Roomba vacuums and Tesla Wall Connectors.
The available settings match each integration: some let you change the host address, while others also accept connection options or credentials. Where supported, a device identity check prevents accidentally replacing the original device with a different one. Existing pairing details are reused for connections such as IKEA TRÅDFRI and Lutron Caséta.
Cloud accounts get their own routes through the same process. August, Netatmo and ViCare support starting authentication again manually; Seafile accepts changed connection and account details. The options differ by service rather than exposing one identical form everywhere.
