My setup doesn’t require any re-authentication. However, I setup a rule that would do this on its own when it detected an issue. Not sure how often it runs, but it is seemless.
I don’t use their motion sensors with Hubitat, but I do use contact sensors and the integration is very good. I only very rarely have any issues, and when I do, opening and closing the door fixes it.
It is an excellent integration, but remember that it is not supported by Ring or Hubitat, so there is no guarantee of how long it will continue to work.
