In Germany price of kWh is often 4 digits, e.g. 27.13 EUR cent per kWh or 0.2713 EUR. Portal only supports two digits. For the report it would be better to support the exact price with 4 digits if you want a correct report.
FWIW, you can enter 4 digit price in the iOS app (Germany here)
This is needed for german users, I agree.
This would be a nice addition to the portal.
