[dennissiemensma]

Feature

These are integers in the DSMR-protocol, but not in Sweden not Luxembourg:

• phase_power_current_l1
• phase_power_current_l2
• phase_power_current_l3

Consider converting it to decimals, even though it will hit a lot and also cause a lot of trouble in keep it compatible with existing data, so it may not happen.

Reported in #1394 / #1533.
