Hi Marc and welcome,
This will only work when you create a support ticket along with it. Officially this is a users only forum.
But I guessume these peaks are not recorded as a special entity by the dongle itself, it only reports regular usage.
Concerning the peak tax:
Check the Piggy Bank app,
It’s aimed to control your power use regarding Norwegian and Belgium peak tariffs;
in short: it can turn off preferred electric devices when tariff, or power usage, or used energy exceeds defined thresholds;
The Power by the Hour app might be helpful as well.
