I've just noticed that the house loads as reported by the online app differ between V1 and the recent V2.
eg.V1 has my load (LoadYield) for November as 844KWh and V2 (Load) as 875.4KWh
Clearly there must be a reason for this, but it would be nice to know why the disrepency, as it will affect other figures, such as solar generation.
Edit: The mobile app appears to tally with V1.

V1 cloud/app is accurate, it uses the total increasing statistic that is maintained and managed within the inverter - the V2 isn’t using that, I think is using the 5 minute data samples aggregated to calculate the load totals - obviously close but with thousands of samples small rounding errors matter, something has changed recently i’m sure they used to match.
Ok, thank you. So, the mobile app is also currently incorrect then?

Ok strike what I said, I thought something had changed so spoke with one of my colleagues.
In the V2 app and V2 web, Fox now calculate load rather than use the load consumption register in the inverter - lots of reasons to do with some users that have corrupt registers and including external solar generation from 3rd party systems but the long and short of it, is that the new load calculation takes into account system losses, export and battery charge/discharge to produce the load value.
At this time of year when solar is minimal it would appear on a daily basis to be quite inaccurate (because you may charge the battery but not discharge the same amount), the monthly statistics are more reliable because that effect is minimised.
The V1 app and V1 website still use the inverter load register (as does my home assistant) and in my case it is far more accurate than the calculated load figure in the V2 app.
The best advice I would give you is to download the Energy Stats app by Al Priest (available on ios and Android), this produces the information using what the inverter is reporting which I would say for 99% of users is far more accurate.
