@Riser : I never tested this but i think you can do that with RESTAPI from the Meraki and get the data in JSON format
https://developer.cisco.com/meraki/mv-sense/#!rest-api/enable-api
And on other hand in PowerBi
according to the content in the link that the API Reponses in JSON, you can get the data by using "Get Data"-->"Other"-->"Web". And then extend JSON to a table in query editor.
eg. http://jsonplaceholder.typicode.com/posts/1/comments
You can replace it with a link like "http://[school].myschoolapp.com/api/academics/department/?t=[token returned from previous step]" in your link.
Regarding refreshing, you can publish it to Power BI Service and schedule refresh. Let me know if it resolves
