To Reproduce
Steps to reproduce the behavior:

Enter in Webapp or Console:
CurrentSet 0.527
Result:

Debug:API:POST to api/cmnd
Debug:CMD:cmd [CurrentSet 0.527]
Error:EnergyMeter:Calibration incorrect - value is zero
Info:CMD:[WebApp Cmd 'CurrentSet 0.527' Result] Command found but returned error

The value seems to be "used somehow", see screenshot. If I enter a different value, the value in the screenshot changes as well. But after a reboot, the calibration is usually broken again.
