I know this is a late response to the post. But still, if someone in need of a good test automation dashboard based on just few api calls, ARES dashboard(built under Testastra and owned by ZenQ) is a much better option to try and its completely free. Also, its capable of showing current live execution and historical test automation insights.
ARES, is an acronym for Test Automation Results dashboard. It's a TestAutomation framework/tool agonistic solution, that simplifies the collection of Test automation results and their analysis via live dashboard, daily/weekly trends, frequent failures etc. Website: http://www.testastra.com/#ares
Below repo has some code samples, documentation and usage of ARES test automation dashboard:https://github.com/testastra/ARES
Hope it will be helpful !!
