Hi Adam,
Here is my submission for a dash app: Energy Management Dashboard.
There is an example of the app hosted on Digital Ocean: app.
The app can be part of the Energy & Utilities category, more specifically for energy management within a manufacturing site for instance. This is aimed at monitoring energy usage, keeping a stable consumption and identifying energy efficiency improvement.
The data source can be configured to an API (for now random data is used) via the api file. The app displays global site energy consumption (electricity only for now) and can be customised by adding measurement tags in a csv file where tags are used to query data from an API.
If you have any questions let me know!
