The last release broke things for a couple of folks, as the new code requested config parameters in the Integration setup. However, as they were upgrading from a previous version, the new options were not present, so the Integration failed. See issue #24
There isnt a way to force the setup of an Integration after its initial install, even when upgrading - which would have fixed it for those people...
So this release reverts back to only defining the users credentials at Integration setup - as per previous releases, but includes an 'Integration setup' option to change the polling frequencies (its the cog in the Integration against the Hub). Note: changing polling frequencies was a feature request - but it is recommended to use the defaults (or less frequently) - this is discussed in the Disccussion section of the Repo.
If the new release still causes problems, the only solution is to delete the integration and then re-add it - once its been downloaded/upgraded from HACS, or manually.
I have updated the Readme instractions to that effect, and included the changes in functionality.
