Important to remember that restoring a local backup does not change your hub's platform version.
So sort of the third leg of this stool is the Hub Platform Version. Hubitat's built-in apps, integrations, drivers, etc., are provided in Platform version releases. They contain all apps, drivers, integrations, etc. E.g., if Rule Machine is upated to a new version or bugs in RM are fixed, or a new built-in driver or app is added, etc., those are delivered to your hub via a platform version update. For example:
So if you want/need to roll back to a previous version of a built in app, integration, driver, etc., you have to roll back to a previous platform version, which is done via the Hub Diagnostic Tool (Settings>Diagnostic Tool).
