Melcloud vs measured Shelly values

Hi,

Anyone else noted that Melcloud values seems to be very slightly off on air to air heat pump?
Today:
Shelly shows 4.63kWh
Air heat pump shows 5.1kWh

Week:
Shelly shows 20.38kWh
Air heat pump shows 21.8kWh

In real life this doesn’t matter in any way, but just posting this for devs in case there is some small offset on their calculations as I understood these bit weird values that melcloud gives.
