DirectQuery Auto Refresh Dashboard Every 60 Seconds

blackshep01 There are threads on here that have provided solutions such that you would display the report page and have a 3rd party extension refresh the page which should kick off a refresh. Another possible solution that may provide the best route is to use a "Push" dataset. This is essentially using the API's to create a dataset and when you push a refresh the dashboard tiles automatically update.

Another option that I just saw recently but don't know if it applies to your data source off hand would be using Microsoft Flow to Push the data, details here:https://powerbi.microsoft.com/en-us/blog/push-rows-to-a-power-bi-streaming-dataset-without-writing-any-code-using-microsoft-flow/
