Power: These were calculated by a rule from voltage and current measurements since a long time and saved to persistence. It did wrong graphs with doing nothing. And so it was nessecary because the 2 year retention would be bad if i would change calculation to kw and saving to the historical data. So i deciced to enter a “W” in Unit and all was fine for me.

Ok, so looks like something normal/expected with new UoM stuff in OH4.

yeah, i got this from a former discussion with Rich Confusion about UOM on my energy-measurement in Wh displayed in kWh
