Janitza energy readings are a factor of 1000 too high (reported via evcc-io/evcc#30671, affecting a UMG604-E).
Applys a
1000scaler fix to the energy opcodes only (Import*/Export*).Voltage/current/power/frequency/power-factor stay in their base units (V/A/W/Hz/-) and are unchanged.
Verified register addresses and units against the B-Series manual (
