@blr_p You were actually right all this time! Both of the meters I used report 3 metrics, Power, Current, Voltage and both use the same scaling factor.
To debug this, I plotted another graph with voltage*current*0.8 and this line was much lower than the line plotted with power as input.
So I went back and looked at the settings in HA and found this problem(i.e. the scaling factor for Power metric was completely wrong). The real usage of previous fridge was 1-2 units/day which does not seem too extreme to me since it's an old fridge that hasn't been serviced in a long time(plus the door seal is a bit imperfect) and the new fridge's real power consumption is 0.3-0.5 units/day
